video on their device using DivX, which includes DRM, and Rovi is releasing an SDK and certification test kit for HEVC this year for Blu-ray players, TV sets, mobile phones, etc. “Point-to-point satellite
transmission also could be an early adopter segment — but that assumes encoder and decoder pair readiness. While the encoding side is always ahead of the game and widespread
deliverable, I expect the overall H.265 transition to move faster than H.264 did,” he added. Nann expects first commercial deployments of HEVC in ‘closed’ applications such as contribution, and for distribution through OTT and mobile services. “Contribution may be able to adopt HEVC relatively quickly (compared to distribution applications) as they can be implemented with
problem today and the client device will easily be updated to support HEVC, either because it is a device that users replace frequently (smartphone) or because it is flexible to support HEVC as it is (PC). This means OTT delivery of live and on demand content, especially over wireless networks, is likely the first economically viable use case,” added Benoit Fouchard, chief strategy officer, ATEME.
“Contribution applications will come later, and require more robust a complex implementations of the standard than what can be offered by compression vendors at this time.”
Terrestrial imperative
“Terrestrial broadcast will likely be last for actual distribution, but some internal applications (particularly around news gathering and satellites) may be adopted sooner,” said Pallett. “In Italy and for DTTV,
regulation states that all TV screens will have to support HEVC decoding from 2015 in order to switch from MPEG-2/ MPEG-4 to HEVC in a 2018- 2020 time frame,” added Gallier. “There are important discussions in every country about the reallocation of the frequency spectrum between mobile and DTTV applications. This really puts a lot of pressure on DTTV frequencies and consequently on bandwidth requirements,” for which HEVC will be an answer, but it will take time. To complete the HEVC
distribution chain for different
applications will require a combination of new technologies and market drivers, explains Wymbs. For satellite these will be: HEVC encoder uplinks, new/updated STBs or SmartTVs, real adoption of 4K Ultra HD; for cable: HEVC-compatible consumer devices or software encoders, HEVC encoders, strong competitive and market push to 4K adoption; for Telco/IPTV: large capital investment to replace or update legacy MPEG-2 and H.264 STBs and potentially service splits based on targeted customers; for Mobile/Wireless: updated mobile devices and infrastructures; for OTT: “disruptive video delivery companies to stake an early mover advantage in 4K and a concerted push toward proving the long-term economics of OTT over mobile and Wi-Fi networks,” he said. Although cable and satellite will depend on the availability of STBs, “those who don’t go down the HEVC path will be at a competitive disadvantage,” added Grab. The enabling technologies
