Media box with live streaming
A Set-top-Box (STB) is a very common name heard in the consumer electronics market. It is a device that is attached to a Television for enhancing its functions or the quality of its functions. On the other side, the STB is connected to an external source of signal, like satellite, cable, terrestrial or internet. The STB processes the signal it receives, turns it into content, which is then displayed on the television screen or other display device. There are different types of STBs based on what kind of signals it can receive and what kind of processing it can do. The most widely used STBs are DVB STBs, which receive DVB (Digital Video Broadcast) transmission.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

3. Introduction
The current trend towards using the personal computer (PC) as an entertainment
system capable of displaying High Definition (HD) video, gaming, and graphics
content has allowed the PC to become the centerpiece of home media
entertainment systems. In its Chrome 400/500 Series graphics processors, S3
Graphics provides media-centric PC technologies which focus on the “digital
living” room and merge PC and consumer electronic (CE) multimedia
functionalities. Major content providers such as Hollywood movie studios and
game publishers are creating HD media which allow the user to take their
entertainment system viewing to the next level when using S3 Graphics’
solutions for PC-CE connectivity.
HDMI (High-Definition Multimedia Interface) carries high-speed, uncompressed
video and audio data streams across a single cable to simplify device-to-device
connections, and provide the additional benefits of HDMI, as described in more
detail below. HDMI provides a bridge across the PC-CE gap in cross-platform
adoption, which has allowed HDMI, the CE interface of choice, to make inroads
into the PC space, as hardware vendors like S3 Graphics incorporate the
technology into their advanced devices.

4. HDMI Background
The HDMI specification was developed for a variety of reasons:
• Existing HDTV connections, such as component video (YPbPr), were
sufficient for previous generation HDTV sets, but lacked the capability to
support higher frame rates, resolutions beyond 1080p, and greater color
depth per pixel, as High Definition quality increases with the introduction of
each new generation of consumer entertainment devices.
• HDMI digital signals carry more information at higher speeds than past
analog formats such as YPbPr or S-Video. Thus, more options exist as
new features are introduced to take advantage of the faster bit rates.
• The conversion of data from digital to analog back to digital is a lossy
process which degrades the quality of the resulting image, as was
previously done. As digital TV sets are the norm, it is better to keep data in
digital format from the beginning and avoid any digital-analog-digital
conversions to minimize the possibility of introducing errors into the data
stream.
• Previous connection options required separate cables for audio and video,
so cable clutter was inevitable. The HDMI connector design replaced
multiple audio and video cables with a single, high-bandwidth, user-
friendly cable (Figure 1).
Figure 1: Separate A/V cables (left), HDMI cable with A/V

• The industry shift to HD content utilizing Blu-ray™ discs and streaming
video-on-demand (VOD) had movie studios excited, but cautious at the
same time because of the lack of analog cabling IP/content protection
mechanisms that left them vulnerable to copyright infringement and
unauthorized distribution of protected IP/content. The HDMI standard
provides an answer to the industry’s concern by incorporating a high level
of content protection that ensures robust signaling and secure content
from source to destination, using the HDCP (High-bandwidth Digital
Content Protection) protocol. Because of the copy protection ensured by
HDMI, movie studios and game developers fully support this technology
as their CE connection of choice.

5. HDMI is an industry-supported high-speed uncompressed digital interface based
on TMDS (Transition-Minimized Differential Signaling). TMDS was also used as
the signaling for DVI, a predecessor of HDMI. Consequently HDMI is backward
compatible with DVI for interoperability with existing displays. The main
differences between the standards are that DVI carries only video data while
HDMI carries both audio and video data, and does so at a much higher data rate.
There is also a size difference between the two connectors (figure 2), making
HDMI more attractive in small form-factor (SFF) designs.
Figure 2: HDMI connector (left) compared to DVI connector (right)
The example in figure 3 shows a PC displaying a movie on an external device
through the HDMI interface. The system uses HDCP to provide a secure
connection from the Blu-ray disc player to the GPU, across the PCI Express bus,
and then out to the HDMI display device.

There are currently three types of HDMI connectors: Type A, Type B, and Type C.
Type A and C are used for single-link, lower resolution panel TMDS connections
and Type B is used for dual-link TMDS support for high resolution displays. The
Type B connector size is slightly larger than the Type A size because of the dual-
link configuration. The Type C (single-link) connector is a compact design,
targeted for mobile and SFF applications.

6. HDMI Specification
Since its introduction at the end of 2002, the HDMI specification has gone
through a few revisions to support the evolution of higher resolution displays in
the market. S3 Graphics Chrome 400/500 Series processors were designed for
compatibility with the baseline HDMI specification revision 1.3.
HDMI Topology
Figure 4 shows the basic topology of a single-link HDMI interface. There are
three unidirectional differential pair data signals and one differential pair clock
signal to carry audio, video, and auxiliary data. The Display Data Channel (DDC)
is a bi-directional signal used for device communication, configuration, and status
exchange between the source (transmitter) and sink (receiver) device. The
source will read the information located on the sink’s EDID ROM to obtain this
information. The Consumer Electronic Control (CEC) bi-directional channel is an
optional feature that enables the user to control multiple HDMI devices
connected together using a single remote control.

S3 Graphics WP017-B.0

7. The clock channel typically runs proportional to the video pixel rate and is used
by the receiver to recover the data on the three data channels. The pixel rate and
clock channel scale up as the resolution increases, from 25MHz to 165MHz.
When lower resolutions (with native pixel rates below the 25MHz minimum
frequency such as NTSC (13.5MHz)) are viewed, the TMDS link will use a pixel
repetition technique to effectively double the pixel clock to be within the clock rate
specification.
The HDMI link uses three operating modes to transmit data, audio, and control
(CEC/DDC) data: Video Data period, Data Island period, and Control period. The
Video Data period is the period during which the active pixels for an active
display line are sent to be displayed at the receiver. The Data Island period is
analogous to the horizontal/vertical blanking period in analog displays, i.e., the
period during which auxiliary data can be sent. In HDMI auxiliary and audio data
packets are sent during the Data Island period. A Control period is required
between any two periods that are not Control Periods.
At the transmitter, video data is converted from 8-bits to 10-bits (DC-balanced)
and sent across each channel at a rate of 10-bits per clock period. The pixel
format is in RGB 4:4:4, YCbCr 4:4:4, or YCbCr 4:2:2 and will be encoded by the
transmitter based on the source data format and receiver support capabilities.
Devices are required to support at least 24-bits per pixel.
Audio is transmitted at the video clock pixel rate since video dominates the
bandwidth of the HDMI interconnect. Since the video clock rate is different from
the audio rate, the audio data goes through a process called Audio Clock
Regeneration (ACR) at the receiver to recreate the correct audio sample clock at
the receiver.
Auxiliary data is sent across the TMDS channels in an InfoFrame packet format.
Auxiliary Video Information (AVI) InfoFrames tell the receiver the capabilities of
the transmitter (for example. pixel encoding or enhancement support). Audio
InfoFrames describe details about the audio data format and rate so the receiver
can synchronize itself with the incoming audio data.

9. Audio/Video Encoding
Previous generations of graphics processors only needed to process video
(display) data. With the growth in popularity of HDMI, S3 Graphics has developed
methods for incorporating HDMI audio as well as visual data within the same
data stream, to provide compliance and full support for current and future HDMI
specifications. At first glance the idea of providing an audio source to the display
seems non-trivial. The main problems with this type of architecture are that the
structures of audio and video data are completely different and they are located
at different software stacks in main memory. In addition, the processing of audio
data requires a fixed function unit (audio CODEC) to convert the audio data to a
usable form, and any timing skew errors can create lip sync problems, similar to
those that appear in poorly dubbed movies.
Two methods can be used to facilitate the embedding of audio along with the
video stream. The first method utilizes an external chip (HDMI transmitter) that
will sync and embed the audio data provided to it by the system audio output and
the video data provided by the GPU. Once the data is multiplexed together, the
transmitter can output the HDMI signal. This technique is sufficient for basic
HDMI use; however, as the data rate increases, the synchronization between
audio and video could become a problem, since audio typically takes less time to
process than video. Audio is also transmitted during the video blanking (Data
Island) interval, so it has a small sampling window during which it can be
manipulated to prevent timing mismatches with the video.
The best quality HDMI audio/video synchronization is available only when the
audio and video data originate from the same source. With the second method
HDMI transmitter functionality is moved into the same chip that is used to
process both audio and video. S3 Graphics has taken this second, more efficient
route in the Chrome 400/500 Series GPUs by designing a Unified Audio
Architecture (UAA) with an embedded audio controller supporting Dolby® 5.1/7.1
digital surround sound and HD Audio. Both the hardware and the software
support are fully compliant with audio industry standards as well as with the
conventions for PCI Configuration space and Microsoft compatibility guidelines
for Windows® operating systems, including Windows Vista®. Utilizing the S3
Graphics advanced ChromotionHD 2.0 video processing engine, Chrome
400/500 Series processors match video and audio signals to output full resolution
premium HD content for the best visual and surround sound audio quality.
HDCP (Content Protection)
HDCP encrypts HD digital content as it is transmitted from a digital video source
to a sink capable of decrypting the HDCP-protected content for viewing. The
connection (for example, watching HD movies on a digital HDTV connected to a
S3 Graphics WP017-B.0
HDMI for Chrome 400/500 Series Processors 11/17/2008
Page 9 of 10
10. PC) is authenticated with a unique session key that creates a secure point-to-
point connection. This connection is constantly monitored to ensure the
connection is not compromised or bypassed for unauthorized users to view or
copy. If the connection is deemed insecure, HDCP will revoke the session key
and users will not be able to play content at the full HD level. Each device has 40
unique 56-bit secret keys (Device Private Keys) and an identifier (KSV) that is
40-bits long. During authentication the transmitter will request the KSV of the
receiver and determine if it is valid. If the KSVs are valid then the transmitter and
receiver each create a 56-bit shared secret value using the other device’s KSV.
Based on the decoding of the shared secret value, each device can determine if
the connection is legal. If a connection is deemed illegal, a user can still view
media content, but at a very low level quality equivalent to your basic Standard
Definition video. If the connection is between two HDCP devices, then the high
quality of full HD output can be experienced theatrically. The S3 Graphics
Chrome 400/500 Series has an internal keystore ROM and logic to encrypt the
HDCP keys and decrypt the HDCP encryption on the fly.
The secure connection HDMI offers gives HD content providers, such as movie
studios and game developers, the confidence to create enhanced multimedia
content for both consumer and PC markets for the best user immersive
experience. In the past, content providers had copyright protection issues,
especially from PC based devices, so little HD media was made available for the
PC user. As the PC becomes more entertainment centric and capable of
providing reliable content protection, the PC will be viewed as another CE device
in the digital living room by content creators. Thus, they will be in a position to
create new and exciting media not only to extend their market reach but also
provide the PC consumer with more HD content options.
Conclusion
HDMI is a forward looking and expanding technology capable of supporting
market shifts and evolving adaptive standards. As the PC becomes part of the
digital entertainment environment, HDMI support becomes an essential
component of this paradigm shift.
S3 Graphics Chrome 400/500 Series processors provide support for HDMI audio
and video and can be designed into PCs as well as other CE devices. With a
Unified HD Audio and Dolby® 5.1/7.1 digital surround sound architecture coupled
with the ChromotionHD 2.0 video engine and integrated HDCP support, Chrome
400/500 Series processors are able to efficiently process audio and video,
providing a seamless High-definition Multimedia Interface -- the way it was
envisioned to be. The user experience has now truly become Hi-Def™.
