Description
Priority 2 activities will only be initiated on the explicit request of at leastone delegation.
Objective:
Develop a DTH demonstrator with Ultra High Definition TV (UHDTV), Scalable High Efficiency Video Coding (S-HEVC) and Variable Coding Modulation (VCM)
Targeted Improvements:
The combined use of SHVC and VCM could provide between 20% to 30% bandwidth usage efficiencies.
Description:
The definitions of the HEVC video codec and its scalable extension S-HEVC have now been standardized. They enable a progressive increase video quality by sending only delta information on top of an existing base video signal. S-HEVC is backwardly compatible with MPEG-4 AVC video codecs, which are currently in wide spread use. Combined with VCM, SHEVC would allow to optimise satellite bandwidth usage while maintaining high service availability. The activity could be an enabler for UHDTV broadcast, augmenting HDTV, making an efficient use of the available satellite capacity. The activity shall study, design and build a demonstrator, showing in particular backward compatibility on top of an existing service. Conditional Access System / DigitalRight Management aspects shall also be addressed.
