Analog and Digital Triax Systems
5
– Triax cable is ideal for high cross-talk environments such as antenna-,
radar-, and broadcast systems.
– Triaxial connectors and cable assemblies are used where very low-
and high level RF signals are transmitted simultaneously through
cables which are bundled or located in high energy fields caused by
radar or transmitters.
– The voltages transported through the triax cable can be quite high
(up to 180V DC or 250V AC on some systems) to allow long distance
power transfer (resistance can be 5-30 ohms per kilometer).
– Because of high voltages on the cable, there are various special
precautions that are taken in account to monitor earth leakage etc.
to prevent electric shock under fault (damaged cable) conditions.

Digital Triax system
– In digital Triax system Component Digital video (plus other signals) running down the cable in digital from.
Analog Triax system
– In analog Triax system each signal is modulated on a different carrier signal so they do not interfere with
each other (Isolated shields allow the triax to provide multiple functions over one cable through
multiplexing techniques).
– This allows the signals to be combined together and transmitted through the same wire.
– Since only one wire is used in a Triax cable, this allows a wide diameter, low loss wire to be used.
– Using a wide diameter wire naturally results in longer transmission distances without a signal level drop.
– The core provides both power and signal connections, with the return for the power being provided
through the inner screen.
– The outer sheath is commonly used as a protective earth conductor.

Analog Triax Systems
Transmission distances have been measured up to 1700 metres, typically 1500 metres, depending
on camera and CCU, using the combined triax HD pro+ system.

– The screening factor is the ratio of the longitudinal E.M.F. (Electric and magnetic fields) induced in a
copper circuit in the presence a screen, compared to the induced voltage in the absence of a screen.
– The high-quality screening ensures an exceptionally high noise-immunity in an electromagnetic
environment without emitting interferences on other systems.
Screening Factor
The higher the screening factor, the
better the noise-immunity of the cable.

SMF (Single Mode Fiber)
– The relatively small core found in singlemode fiber only allows one path of light directly down the center of the core.
⇒ This keeps the signal intact for up to 100 km and beyond.
MMF (Multi-Mode Fiber)
– The term multimode comes from the fact that light can travel in more than one path through the core of this fiber.
⇒ The relatively large core allows light to travel both straight down the center or to bounce from side to side in a zigzag pattern.
⇒ Up to 300m (at 10 Gb/s to 100 Gb/s data rates), Much less bandwidth, Easier to work with in terms of flexibility and robustness
Fiber Cables Types
MMF Grades (OM3 & OM4) (Optical Multi-mode)
• OM4 <3.0 dB/km (more widespread)
• OM3 <3.5 dB/km (more popular with the advent of 40 GbE and 100
GbE networks)

SFP (100 Mb/s to 8 Gb/s)
SFP+ (10 Gb/s)
– Data rates up to 16 Gb/s (For broadcasting and media IP routing for 10 GbE connectivity)
– Multiple different variants (and vendors) that are not all interoperable

– The ferrule is a small cylinder used to mount the fiber and acts as the alignment mechanism. The end of
the fiber is located at the end of the ferrule.
– The fiber comprises 2 layers: the cladding and the core.
⇒ The cladding is a glass layer surrounding the core, which prevents the signal in the core from escaping.
⇒ The core is the critical center layer of the fiber and the conduit that light passes through.
Fiber Connector
Particles closer to the core will have
more impact than those farther out.

Wavelength Multiplexing Systems
33
Multiplexing
– “Multiplexing” is a technology that allows multiple signals with different wavelengths to be transmitted
together over a single optical fiber.
– Three general types of multiplexing — WDM, CWDM and DWDM — offer increasing signal-carrying
capacities, as described below
1- Wavelength Division Multiplexing (WDM)
– WDM is the simplest form of multiplexing and uses two wavelengths of 1310nm and 1551nm (Allows 2
signals to be multiplexed).

34
2- Coarse Wavelength Division Multiplexing (CWDM), Standard: ITU G695
– CWDM systems use 8 wavelengths (20nm grid) primarily between 1471nm and 1611nm.
– It is also possible to add 8 more between 1271nm and 1451nm to allow a maximum of 16 wavelengths to be carried as a
single multiplexed transmission.
– The E- and U/XL-bands have typically been avoided because they have high transmission loss regions.
Center wavelengths of CWDM
O-band: Original band
E-band: Water peak band
S-band: PON (passive optical network) downstream
L-band: Low attenuation
C-band: Lowest attenuation

35
2- Coarse Wavelength Division Multiplexing (CWDM), Standard: ITU G695
– Canare’s CWDM optical converter uses a DFB (distributed feedback) laser, which offers a much tighter spectrum than FP
(Fabry-perot) lasers.
– Up to 16 different wavelengths fall within 1271nm and 1611 nm in 20nm intervals.
– The wavelengths in the 20nm grid between 1391nm and 1411nm are not used because their proximity to the water peak
results in too much attenuation.
Optical Fiber Transmission Loss Characteristics
O-Band: 1270nm to 1370nm
E-Band: 1371nm to 1470nm
S-Band: 1471nm to 1530nm
C-Band: 1531nm to 1570nm
L-Band: 1571nm to 1611nm

36
3- Dense Wavelength Division Multiplexing (DWDM)
– The differences between CWDM vs DWDM lie in channel
spacing, transmission distance, modulation laser, costs,
etc., which has reflected in their practical applications.
– CWDM systems use 8 wavelengths (20nm grid) primarily
between 1471nm and 1611nm.
– PacketLight’s DWDM over CWDM solution enable to
increase the exiting CWDM network capacity by
inserting into any of the of the 4 CWDM wavelengths -
1531nm, 1551nm, 1571nm and 1591nm - a set of
additional 8 DWDM wavelengths, separated from each
other by 0.1nm.

37
3- Dense Wavelength Division Multiplexing (DWDM), ITU G694 Standard
– In practice, DWDM frequency is usually converted to wavelength.
– DWDM typically has the capability to transport up to 80 channels (wavelengths) in what is known as the Conventional
band (C-band) spectrum, with all 80 channels in the 1550 nm region.
– Allowing huge amounts of data to travel in one single network link, DWDM is ideal for long-haul transmission as the
wavelengths are tightly packed together.
Conventional band (C-band) spectrum
• ITU G.694.1 standard DWDM region is from
1528.77nm to 1563.86nm that resides mostly within
the C band (C-Band: 1531nm to 1570nm).
• DWDM can have 100GHz (0.8 nm) wavelength
spacing for 40 channels, or 50GHz (0.4 nm)
spacing for 80 channels.

38
Single Fiber vs Dual Fiber
– Single Fiber Transmission
• Single fiber transmission method, namely, is a kind of bi-directional
communication over one single fiber.
• This system utilizes two identical sets of wavelengths for both directions over a
single fiber.
• Individual channels residing on the single fiber system may propagate in either
direction.
– Dual Fiber Transmission
• The dual fiber transmission method is comprised of two single fibers—one fiber is
used for the transmit direction and the other is used for the receive direction.
• In a dual fiber transmission system, the same wavelength is normally used in both
the transmit and receive directions.
• The second fiber may serve as
 a backup fiber as in a redundant system
 it may provide an optical path in the opposite direction.

Reasons for Migrating to Fiber Optics
39
– Trunk lines carry many different kinds of signals—
video, synchronization, audio, control, power
supply—and consequently they’re usually
comprised of numerous different types of cables.
– But, converting these disparate signals into
optical signals and transmitting them using fiber
optic cables greatly reduces the need for so
many specialized cables.
– Converting trunk lines to fiber optics makes it
much easier to design and upgrade equipment
and systems, because once laid these lines can
be used with considerable flexibility. Example of an Optical Fiber Trunk Line
Fiber optic systems are used in signal transmissions within a single
broadcast station, or between a main building and an annex building.

Important Fiber Optic Line Considerations
40
1- Minimum Light Receiving Power
– In optical transmission, transmission quality is evaluated by the relationship between “light receiving
power” and “error rate.”
– Error rate is dependent upon the signal to noise ratio (S/N), but since the noise level is thought of as being
at a set level independent of the signal strength, the strength of the signal (light receiving power) at the
receiver influences S/N considerably, in turn affecting the error rate.
– Therefore, to maintain a specified transmission quality, it is necessary to design light receiving power to be
above the minimum light receiving power of the receiver.
Wavelength= 1310 nm
Wavelength= 1200-1620nm

41
Wavelength= 1310 nm
Wavelength= 1200-1620nm
1- Minimum Light Receiving Power
– Red graph: we can estimate that to get an error rate of
2 × 10−18
(to ensure a probability of 1 for transmission
errors during 10 years of continuous operation), the light
receiving power of the OE-151 must be set greater than
-24.3dBm assuming the signal source and EO-100B are
connected by a coaxial cable 1 meter in length (SMPTE
connection standard).
– Blue graph: we can estimate that If the signal source
and EO-100B are connected by a coaxial cable 190
meters in length, then the OE-151 light receiving power
must be more than -23.6dBm, from which we can see
that the light receiving power deteriorates by about 1dB
as compared with the connection standard.

190m

42
2- Loss Budget (LB)
– Loss budget is the difference between the optical power output (P1)
from the EO converter and the light reception sensitivity (P2) of the OE
converter. Example
– In EO/OE system design, following parameters have to be calculated
so that they are less than the loss budget (LB) of the optic link.
⇒ cable attenuation loss
⇒ connector insertion loss
⇒ fusion splice connection loss
⇒ Mux/Demux insertion loss
– For HD/SD-SDI system, since the Mux/Demux loss is greater than that of
the fiber attenuation loss, it would be essential to consider such loss
elements when you configure the system.

− With its unmodulated, uncompressed, and
widest band-transmission capability, optical
fiber transmission offers a range of benefits for
HD content creation.
– Optical transmission systems send the raw
signal data converted into light, while triax
systems electrically modulate the signal,
resulting in generation of noise.
– The electric-to-light and light-to-electric
conversion of an optical transmission system
does not generate any noise.
– The optical fiber cable itself is a very thin and
flexible glass fiber, which is just as easy to
handle as a conventional triax cable.
Hybrid Fiber-Optic Camera Cable Specifications

47
– The hybrid fibre optic cable and connectors are more expensive than Triax cabl.
• In fact the difference in price between digital-grade RG-11/U triax cable and the hybrid fibre optic cable is very
small (both around £3 - £6 per metre depending on quality).
• The cost of a pair of triax connectors is around £100.
• The cost of a pair of SMPTE hybrid Fibre Optic connectors, including fibre optic contacts, is around £170.
– The termination of this type of cable is more complex, and time consuming.
• The termination + test cost of a pair of triax connectors is around £110, and the cost to terminate + test a pair of
SMPTE Hybrid fibre optic connectors is around £250.
– The termination tooling required is much greater.
• The tooling required to terminate hybrid connectors using the standard epoxy and polish contact is approximately
£14K (comprising Polishing machine/jig @ £11,500, curing oven @ £500 and general tooling £2000 approx).
– The test equipment necessary to ensure that all is working correctly is more expensive.
• The Fibre Optic test equipment costs approximately £13K (Loss test set, video inspection scope, OTDR (optical time-
domain reflectometer), Return Loss meter).
– Contacts get dirty easily and are difficult to keep clean.

– Where the cameras are powered over the hybrid cable from the CCU, distances of over 2 km are
commonplace.
– The distance in this case is only limited by the voltage drop in the electrical power part of the hybrid cable
assembly.
– In the event that distances greatly in excess of 2km are required special 12mm diameter “long haul”
cable, with double the number of power conductors is available.
– Some HDTV camera manufacturers have decided to go almost exclusively for fibre-based systems (e.g.
Sony, Ikegami) and, using locally powered cameras, the digital HDTV signal can be sent well over 20km of
single mode fibre, without the need for a repeater.
External Power

54
Fiber-optic is future-proofing
– With regard to installations, equipping new studios, OB vans or sporting venues solely with triax limits the
possibilities of the type / manufacturer of camera systems which could be used.
– The single mode fibres used in the ARIB / SMPTE hybrid cable specification have a very high bandwidth
(>100GHz.km) which is much greater than required for today’s HDTV systems
⇒ Excellent Level of “Future-proofing“.

Hybrid Fiber-Optic Camera Cable Specifications, SMPTE 311M
– The primary English language specification for HDTV broadcast cables is SMPTE 311M -1998, with 6 main
manufacturers of the cable but each with varying properties. Some are more suited to indoor applications
and some to the harsher outside broadcast environment.
⇒ For outside broadcast, tensile strength, crush resistance, abrasion and tear resistance and repeated
bend/twist capability are all critical features.
⇒ For in building use greater flexibility and flame / smoke retardence are required.
– Factors that affect cable reliability are:
• Extent of braid coverage - SMPTE states 82% which is probably too low for OB.
• Fibre material - e.g. pvc jacketed vs. nylon jacketed.
• Cushioning material - polypropylene vs. cotton
• Cable manufacturing construction. Fibre is delicate and excessive movement within the cable can result in micro-
bending of fibre and signal failure - good cable construction and materials is essential for reliability.

58
Field Termination Approaches
– If an O.B cable gets damaged, the best solution is to run out a spare factory terminated cable.
– The tooling required to terminate hybrid connectors using the standard epoxy and polish contact is
approximately £14K (comprising Polishing machine/jig @ £11,500, curing oven @ £500 and general tooling
£2000 approx).
– There are occasions when “field termination” might be needed, which can be provided by fowling
options:
1) pre-terminated contacts (cleave and crimp pre-terminated contacts)
2) fibre splicing (fusion splice)
− For both the pre-terminated contact and fusion splice options it is beneficial to have fibre optic test
equipment available as outlined above, though not absolutely necessary.
Price Date: 2007

59
1- Cleave and crimp pre-terminated fibre optic contacts
− The tooling used for this repair is much less expensive (approximately £2000), and a single quick-repair
connector can be fully terminated in approximately 45 minutes.
− The crimp and cleave style contacts have a relatively short life and should really only be used as a “get
out of trouble” repair, not a permanent solution.
− The cable should be fully re-terminated when time permits, either in-house with the full tooling and trained
personnel or by sending the cable to a suitable termination house for repair.

2- To fusion splice fiber cable to factory made patch cords
− By means of a portable automatic fusion splicer it can be field terminated, making it suitable for projects
where application constraints prohibit the use of pre-terminated camera cables.
− This requires a fusion splicer costing around £8000.
− Fusion splices combine the best of pre-terminated contacts and continuous fibre connectors.
− Spliced fibre connections, protected by LEMO's 3K.93C connector shells, have negligible insertion loss, and
are not affected by temperature extremes.

Fusion Splicing for LEMO's Fibre Optic Connectors and Cables
− On-site fusion splicing eliminates the difficulty of polishing.
− The pre-polished fibre contacts are tested and inspected to ensure
100% compliance.
− Use splicing technology with cables, patch panels and bulkhead
mounted connectors.
− Pull cable through conduit to required lengths (or laid-in cable)
and terminate on-site rather than pre-ordering complete cable
assemblies with estimated lengths.
− This eliminates waste and the potential for damaged connectors.
− Use this system to splice other standard 125μm fibres with 250μm
and 900μm coatings.

Water Ingress and Cleaning
– Proper termination of the cable is essential to prevent water ingress and/or damage to fibre within the
connector.
– Secure water proof end caps are essential to prevent dirt and water getting in to the unconnected ends.
– Any connector that is filled with water will have problems if it is used to handle power.
– In some cases hybrid cable assemblies have somewhat unjustly earned a reputation for being unreliable.
In fact most problems that arise can be attributed to the fibre optic ferrule endfaces becoming dirty.
 The first rule is “inspect the endface and if it isn’t dirty don’t touch it”.
 If the fibre is dirty it needs to be cleaned
 The cleaning process is simple and quick, with minimal tooling required.

LEMO 3K.93C.Y Series Connector

90
– The 3K.93C.Y Series connector was designed in 2017.
– The new design has less components and offers innovative features- including the FS contact. The FS
contact is a re-design of the original F2 contact developed in 1992.
– The simplified FS contact has a reduced number of components and fits into a new connector shape.
– The downside is no component or spare part is compatible with the previous LEMO connector version.
– The new insulator is made in two sections and the sideways insertion of the optical contacts prevent any
push-back on the optical contacts.
– No more optical extractor are required to remove these contacts.
Advantages:
⇒ New design allows easy fibre length adjustment.
⇒ No more half shells are required.
⇒ Increased space for the fibres to move “more” freely in the connector.
⇒ Reduced curing time for the optical contacts (new design allows epoxy to cure within 20 minutes).
⇒ Simplified potting of the rear of the connector, offering extended resistance.

TMDS (Transition Minimized Differential Signaling)
− The color information is coded as 10-bit resolution by the so-called
TMDS® encoder for bandwidth minimization and DC balancing.
− TMDS Clock is 1/10 bit transfer rate.
− It uses current drive to develop the low voltage differential signal
(LVDS) at the receiver side of the DC-coupled transmission line.
− The link reference voltage 𝐴𝑉
𝑐𝑐 sets the high voltage level of the
differential signal.
− The low voltage level of the differential signal is determined by the
– current source of the transmitter
– termination resistance at the receiver
− The termination resistance (𝑅𝑇) and characteristic impedance of
the cable (𝑍0) must be matched.

126
HEC (HDMI Ethernet Channel)
It provides a 100Mbit/s bi-directional link. TMDS
TMDS (Transition Minimized Differential Signaling)
• An encoder for bandwidth minimization and DC balancing.
• It interleaves audio, video, and auxiliary data.
• During the video data period, the pixels of an active video line are
transmitted and during the horizontal and vertical blanking intervals,
audio and auxiliary data are transmitted within a series of packets.
• The control period occurs between video and data island periods.
DDC (Display Data Channel)
• It is a simple communication channel based on the Inter-
Integrated Circuit (𝑰𝟐𝑪) Protocol spec that enables the display to
communicate its supported display modes and enable the host
to adjust parameters such as brightness and contrast.
• The DDC carries two kinds of data: HDCP and EDID.
• EDID is the data that a display device sends to a source device.
ARC (Audio Return Channel)
It is an audio link meant to replace other
audio cables between for example the TV
and a speaker system.
CEC (Consumer Electronics Control)
• It is used to pass user controls to all interconnected electronic
devices.
• It provides high level control functions between all of the
various products in a user's environment.
• It allows the user to control up-to ten enabled devices
connected through HDMI.

DDC (Display Data Channel)
− A pair of wires in HDMI interface.
− The DDC connects multiple devices on the same pair of wires.
− The protocol chosen by the DVI and HDMI to manage this multi-device two-way communication is 𝑰𝟐
𝑪.
− The DDC carries two kinds of data:
• EDID (Extended Display Identification Data) is the data that a display device sends to a source device
about its resolution, refresh rate, colour space, audio format and so on, so that the source device can
generate the required signal to match (It enable automatic detection of the monitor’s capability).
• HDCP (High-bandwidth Digital Content Protection) is the copyright data. First, the source device
requests the key from the display device and validates it. Then, the source device sends the
encrypted AV content over four TMDS pairs and the decryption key over the DDC.

− High-bandwidth Digital Content Protection encrypts data over HDMI.
− HDCP helps bring high-definition digital content to consumers by providing copy protection over HDMI
− Developed by Intel Corporation to prevent copying of digital audio and video content as it travels across
HDMI, DVI etc.
− Supported by the majority of CE manufacturers, government and content providers.
− Emphasizes that HDMI is a smart cable

HDMI TMDS Clock to Pixel Relationship
− The color information is coded as 10-bit resolution by the so-called transition minimized differential signaling
(TMDS®) encoder for bandwidth minimization and DC balancing.
− TMDS Clock is 1/10 bit transfer rate
8 Bit Per Component Example:
• 8 bits per color = 24 bits per pixel
• Each 8 bit color value is coded as a 10-bit TMDS code, mapped to one Tx lane
• TMDS clock runs at 1/10 the serialized bit rate, so …
• 1 TMDS clock = 1 pixel
− For 1600x1200@24bpp, 60Hz refresh, pixel clock ~162MHz
− TMDS Clock = 162MHz; Bit rate per lane = 1.62GT/s
133

Low Voltage Differential Signal (LVDS) Driver.
− The differential signal helps to cancel noise and allows the use of lower voltages for signaling.
− Ultimately allowing for higher data rate.

HDMI Cable Limitation
– HDMI is a fragile interface, not least because of the difficulties of manufacturing twisted-pair HDMI cable
to the fine tolerances required to handle the extraordinary bandwidth requirements of the HDMI signal.
– The primary limiting factor is cable length.
– 15m is generally considered the maximum reliable length, but in practice with higher resolutions and
frame rates, this limitation is much shorter.
– Several methodologies such as following approaches have been employed to reduce the error rate of
longer cable length.
• Improved cable deign and characteristics
• Active repeaters (error correction)
• Fiber optic encoder/decoder (replacing the cable altogether)

139
HDMI Cable Limitation
– The “Eye Pattern” is what the [TMDS] digital signal looks like on an oscilloscope.
– The traces of many 1s and 0 overlap together on the oscilloscope to form a pattern that resembles an eye
shape.
– The longer the cable length, the poorer the data signal will become.

What is a USB Type-c (2013)?
− USB 2.0 (up to 480 Mb/s): the main drawback is low currents (not more
than 500 mA), which often caused problems when connecting
external drives.
− USB 3.0 (Blue USB, up to 5 Gb/s, 8-pin): maximum current is 900 mA.
• Such a small current of 900 mA to power the laptop battery at 8000-
10000 mAh is clearly not enough).
• More demanding power accessories began to appear on the market.
• The manufacturers’ tendency to make devices thinner and more
compact forced them to abandon ports such as HDMI, Thunderbolt,
classic USB, Ethernet.
− USB Type-c: 24-pin in USB 3.1 Type C (to provide normal power supply).
171
USB, Universal Serial Bus
• 4 pairs of contacts provide power and ground
• 4 contacts are responsible for data transmission at
speeds less than SuperSpeed
• 8 pins transmit data at high speeds SuperSpeed
• 2 pins auxiliary
• 1 contact is responsible for data configuration
• 1 pin provides +5 Volt power for active cables
• 2 pins determine cable orientation (which side is
inserted)

172
• USB-C is the latest connector type developed by the USB
Implementer’s Forum (USB-IF).
• In their effort to consolidate many different capabilities
previously reserved for specific cables, into one standard
connector type, USB-IF’s new and rapidly evolving

Thunderbolt Technology
− Thunderbolt is the brand name of a hardware interface developed by Intel (in collaboration with Apple)
that allows the connection of external peripherals to a computer. Originally codenamed Light Peak.
− Thunderbolt is a high-speed protocol that can dynamically adjust data and video bandwidth depending
on the device and/or application.
− Intel developed Thunderbolt with Apple, and perhaps not coincidentally, OEM systems based on rival
AMD’s (Advanced Micro Devices) CPUs have never had this technology.
− AMD officials dismissed the need for Thunderbolt, even though officials indicated that they could ship
Thunderbolt controllers without the need to integrate them.

180
• Ice Lake is Intel's codename for the 10th generation Intel Core mobile processors (CPU).
• Tiger Lake is Intel's codename for the 11th generation Intel Core mobile processors (CPU).

181
Thunderbolt 3 includes USB 3.1

182
− Thunderbolt combines PCI Express (PCIe) and DisplayPort (DP) into two serial signals, and additionally
provides DC power, all in one cable (Dual-protocol (PCI Express and DisplayPort)).
− This two fundamental I/O protocol is combined in Thunderbolt technology within a single meta-protocol.

− Thunderbolt technology is based on a new architecture with full-duplex
links. Thunderbolt port is capable of providing the full bandwidth of the
link in both directions.
− The Thunderbolt protocol physical layer is responsible for link
maintenance including hotplug detection, and data encoding to
provide highly efficient data transfer.
− The heart of the Thunderbolt protocol architecture is the transport layer.
− DisplayPort and PCI Express protocols are mapped onto the transport
layer.
− Mapped protocol packets between a source device and a destination
device may be routed over a path that may cross multiple Thunderbolt
controllers.
184

− At the destination device, a protocol adapter recreates the
mapped protocol in a way that is indistinguishable from what
was received by the source device.
− Thunderbolt technology-enabled product devices appear as
PCI Express or DisplayPort devices to the operating system of the
host PC. So available standard drivers are capable of using
them.
− Host-side Thunderbolt controllers have one or more DisplayPort
input interfaces, a PCI Express interface along with one or more
Thunderbolt technology interface.
− A single chip, the host-side controller enables system vendors to
easily incorporate Thunderbolt technology into their designs.

HD In Practice
Camerawork
− Four times the resolution, Five times the pixels.
− Tight focus is really important.
− Tracking shots need careful focus control.
− Focus aids help a lot (viewfinder detail and crispening).
− Use skin detail, Requires good makeup.
Camera craft
− HD cameras have a different color gamut.
− Some customers find an improved red response.
− Greater care in handling human flesh tones.
(Also affects makeup)
− Viewfinders present particular challenges
− Viewfinder lag may require a degree of forward thinking.
− Resolution may not be good enough.
208

HD In Practice
Editing in HD
− Greater storage required.
− Higher bandwidth input/output required.
Lighting
− Increased lighting levels provide greater depth of field.
− HD has a greater sense of 3D without a narrow depth of field. We no longer need to use a shallow
depth of field to help create the 3D image.
− With HD a too shallow depth of field looks out of place.
− On HD productions we light to a higher level than is usual for our standard definition studios in order to
obtain a deeper depth of field.
209

HD In Practice
Makeup
− Broadcasters are realizing that makeup is important
• Increased resolution shows up facial features much more.
• The greater visual detail achievable requires a more evenly distributed make-up application method
for faces.
− Actors, presenters, and other on-screen talent
