This document provides an overview of the development of DVB-H (Digital Video Broadcast - Handheld), a digital television broadcast standard for handheld devices. It describes how DVB-H was created to address the need for mobile TV by modifying DVB-T to include features like time-slicing for power savings, additional error correction, and signaling improvements. Key aspects of DVB-H like its use of MPEG transport streams, IP-based service information, FLUTE and RTP for content delivery are summarized.
DVB is a set of standards that define digital broadcasting using existing satellite, cable, and terrestrial infrastructures.
The term digital television is sometimes used as a synonym for DVB
At DVB Wolrd 2015, Copenhagen March 24th 2015, Mr. Kenneth Wenzel from Open Channel in Denmark shared the experiences gained, from being the world’s first to deploy and trial digital radio based on the new DVB-T2 profile T2 Lite.
The presentation proved the superiority and robustness of T2 Lite for digital radio, instead of DAB+, which is widely regarded as obsolete today.
Hong Kong’s independent regulator issued July 13th 2017 an amended mobile TV license to HKMTV, which allows it to change its transmission technology from CMMB to DVB-T2 Lite. The new transmission standard will be implemented within 12 months.
In areas where there are multiple original networks (Original Network IDs) as Copenhagen, where you can receive DTT signals from both Denmark (red) and Sweden (green), the DVB-T2 device (NorDig IRD) shall first sort/list all services from Denmark (Original Network ID = 0x20D0), before sorting/listing the next original network, here Sweden (Original Network ID = 0x22F1).
Within DVB’s SI code allocation (ETR162), there is normally an un-written code of practise for digital terrestrial networks that the original network id has been allocated by the DVB office to the value of 0x2000 plus the country’s ISO 3166 Country code value.
This is true for all countries, except three countries DTT network:
› Swedish DTT (0x22F1), Hungarian DTT (0x22C7) & Portugal DTT (0x22C8)
Open Channel has applied for permission to conduct a 3-year DRM+ trial on the FM band in Copenhagen from April 2019.
DRM+ (Mode E) is a new digital radio broadcasting standard above 30 MHz up to 240 MHz.
DRM+ provides bitrates between 37.2 and 186.3 kbit/s depending on robustness level, using QPSK or 16QAM modulations and 100 kHz bandwidth.

Space-based solar power (SBSP) is the concept of collecting solar power in space (using an "SPS", that is, a "solar-power satellite" or a "satellite power system") for use on Earth.It has been in research since the early 1970s. SBSP would differ from current solar collection methods in that the means used to collect energy would reside on an orbiting satellite instead of on Earth's surface.

How can your business benefit from going serverless?Adrian Hornsby
Serverless architectures let you build and deploy applications and services with infrastructure resources that require zero administration. In the past, you had to provision and scale servers to run your application code to install and operate distributed databases and build and run custom software to handle API requests. Now AWS provides a stack of scalable fully-managed services that eliminates these operational complexities. In this session, you will learn about the basics of serverless and especially how your business can benefit from it.

Self-Driving cars. Commercial drones. Smart cameras. Movie and music creation. Powerful & intelligent robots. Over the past few years, a new revolution has brought AI almost to the level of science-fiction. However, most companies are not worried about far-off futuristic applications of AI, they want to know what AI can do - today - for their organisations. Distinguishing the hype from reality can be a bit confusing, especially when you consider the attention that AI gets from the media and commentators. So, how can your organisation get started and put AI to work for you? That is the question I will answer in this talk. From greater customer intimacy, increasing competitive advantage and improving efficiency, I will discuss and show how AI can be used today and help the organisation in more impactful ways.
Chaos Engineering: Why Breaking Things Should Be Practised.Adrian Hornsby
As presented at the AWS London Summit 2018
With the rise of micro-services and large-scale distributed architectures, software systems have grown increasingly complex and hard to understand. Adding to that complexity, the velocity of software delivery has also dramatically increased, resulting in failures being harder to predict and contain.
While the cloud allows for high availability, redundancy and fault-tolerance, no single component can guarantee 100% uptime. Therefore, we have to understand availability but especially learn how to design architectures with failure in mind.
And since failures have become more and more chaotic in nature, we must turn to chaos engineering in order to identify failures before they become outages.
In this talk, I will deep dive into availability, reliability and large-scale architectures and make an introduction to chaos engineering, a discipline that promotes breaking things on purpose in order to learn how to build more resilient systems.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

10. How did it all started ...
• DVB-M (CM) Group formed based on reports
– launch in 2002 (Juha Salo, Nokia)
• Requirements accepted by CM mid-2002
– Co-existence with Mobile Phones
– Indoor scenarios
– Single antenna reception
– Reduced power consumption
• DVB-M (TM)
• Evaluate DVB-T for those requirements
11. DVB-T in short ...
• December 1995, DVB publish the DVB-T standards
(EN 300 744)
•

12. DVB-T in short ...
• Terrestrial Digital Television Standard
• One-to-many broadband wireless data transport
– Video, audio, data (also IP, late addition)
– Scalable (cell size up to 100km)
– Huge capacity (54 channels, 5-32Mbit/s)
• Lead to the ASO (analog switch off)
• MPEG-2 transport stream based (flexible)
• OFDM multi-carrier modulation (2k and 8k mode)
– Carrier modulation QPSK, 16QAM, 64QAM
• All in all, DVB-T is pretty good and flexible
• So what is wrong really ??
13. DVB-T in short …
• OFDM, multi-carrier modulation (2k and 8k mode)
• Each sub-scarrier is modulated with conventionat
schemes (QAM)
2k: larger inter-carrier
→ Tolerance Doppler
8k: small inter-carrier
→ large symbole duration
→ maximum echo delays

15. So why not DVB-T ??
• Designed for rooftop reception
• No power saving mechanism
• Inadequate impulse noise protection
16. How did it all started ...
• DVB-H (TM)
– Call for technology (Jan/Feb 2003)
– 12 responses
– 3 concept formed in April
– Final concept in August
– Standard accepted by TM in January 2004
– By ETSI in the end of 2004
» Now we have a new physical layer standard for
mobile devices
17. How did it all started ...
• DVB-CBMS (TM)
– Nokia’s initiative to ‘complete’ the work
• All layers need to be standardized
– 2003: early specifications of the interface to the
terminal for early trials
– 2004: detailed technical requirements for an
quot;IPDC in DVB-Hquot; system
• Call for technologies started in autumn 2004
• First standards to TM in fall 2005
• DVB-IPDC to ETSI in 2006/2007
18. What really is DVB-H for ??
• DVB-H aims at providing digital TV reception to
mobile devices
• Combines traditional TV broadcast standards
with element specific to handheld devices
– Smaller screen
– Mobility
– Antennas
– Indoor coverage
– Reliance on battery power
19. What is DVB-H ??
• Transmission of data mainly done as IP frames
– Internet Protocol
• New video compression scheme (h.264)
– For lower bitrate and smaller screen size
– Approx. 390 Kbit/s per stream (mpeg2 was 3-4 Mbit/s)
• More suitable for broadcasting to mobile
environment
20. New features of DVB-H ..
• Time-slicing
• power saving and frequency handover
• MPE-FEC
• additional protection of the data link layer
• New 4k mode:
• trade-off between cell size and mobile reception
capability (Doppler and echo delays)
• New signaling scheme
• modified TPS bits and additional mpeg PSI/SI
tables (INT)
21. Time-slicing
Service 1
Capacity
Channel
Service 2
Service 3
Service 4
Time
• In DVB-T, services are multiplexed on the TS level at very high
frequency
• Service almost sent in parallel
• Very hard for decoder to only focus on one stream (specific TS packets)
• All data must be received, leading to high power consumption
• 8k, 16QAM ½ 1/8, 11.06Mbit/s
• 7412 TS packets/OFDM symbol, 1 symbol = 1008us
• 1 TS packet every 136us
22. Time-slicing
Burst
Off time
Capacity
Channel
Time
• IP service organized so that each services use
the full channel capacity one after another
– Burst transmission
– Seamless frequency handover
– Longer initial tunning delay
23. Time-slicing
• The off-time period provides up to 90% of power saving
• The receiver has to know when the next interesting
burst (service being consumed) is arriving
– Real-time signalling
– PSI/SI not sliced

Time
• Time-slicing permits the monitoring of neighboring cells during off-
time
• In DVB-T, would need 2 frontends
25. MPE-FEC
• Multi-Protocol Encapsulation with Forward Error Correction
– Reed-Solomon coding on IP datagrams
• Higher error resistance
– Virtual interleaving, FEC placed in separate sections
– Receiver can ignore FEC sections

27. 4k mode
• 4k: 3409 carriers
• Compromised between 2k (1705 ca.) and 8k (6817 ca.)
• Increased mobility by two compared to 8k
• SFN cell size double compared to 2k
• 4k is an option, 2k and 8k can be used for specific
environment (rural, dense city)
28. Signaling with TPS-bits
• Physical layer extensions
• Reserved information channel with tunning
parameters (Time-slice, MPE-FEC, Cell ID, ...)
• Very robust signalling scheme allowing TPS
lock even with very low C/N values
• Faster to access signalling than demodulating
and decoding the PSI/SI or the MPE sections
30. Service Information
• Main difference between DVB-T and DVB-H
• DVB-H does not utilize all the service
information table defined by DVB (PSI/SI)
• DVB-H uses IP based Information system,
“service guide” rather than the traditional PSI/
SI from DVB
35. DVB-H delivery mechanisms
• File Delivery over Unidirectional Transport
(FLUTE) protocol
– File download (download first, then consume)
• Real-time Transport Protocol (RTP)
– Streaming (consume while downloading)
– Without RTCP report (broadcast)
36. FLUTE
• Asynchronous (non-real time) broadcasting of
audio, video, and data files
• Download and store at the receiver for future
playback
– IETF RMT WG
– RFC 3926
“FLUTE is a protocol for the unidirectional delivery
of files over the Internet, which is particularly suited
to multicast networks. The specification builds on
Asynchronous Layered Coding (ALC), the base protocol
designed for massively scalable multicast distribution.”

39. RTP- Real-Time Transport Protocol
• RTP provides end-to-end network delivery
services for the transmission of real-time data
• RTP is network and transport-protocol
independent, though it is often used over UDP.
40. RTP- Real-Time Transport Protocol
• Use SDP file extracted from ESG to get tune in
and decoding information necessary for the
player to understand and decode the RTP
stream and its payload
