Produced over 64 million STBs; launched and owns 6 satellites;

Participates in DTV standards developing (EchoStar participating IMPALA committee- www.impala.org, which created MHEG standard)

Challenges in Digital TV area

Development/ Standardising markets Developing of Embedded Systems in as short time as

possible. Standardising markets is developing of standards

addressing markets’ needs. The goal is to reduce operational costs on developing embedded systems.

Test Pay-TV service providers have millions of users. Each

call of a user to call centre of a provider costs some money. So price of bug is huge.

Security This issue is common for whole industry. Pay-TV

providers are using conditional access systems to avoid breaching of copyright of their content.

What is STB?

STB 8 years ago SD Zapping through the

channels Electronic program

guide Security

STB Now HD (3d) DVR (Time shifting) Sling (Place shifting) 2 TVs support (4 video/audio

streams management in RealTime) 2 Remotes support (ZigBee, IR,

UHF) Wireless/integration with Home

devices (TV, StereoSystem, Modem)

Internet access, Applications on STB, Games.

Conclusion

Outlined area of interest of the DTV engineering Happy fruitful conference for the organizers Wishing the best to the other participants with their presentations Industry – to get closer to universities and research communities Research communities and university – to get closer to industry Everyone - Enjoy Moscow
