DVB - Especificaciones 8K - 2021

The 数字视频广播 steering board has updated several of its specifications to support the delivery of 8K UHD video services.

These specifications, which extend existing support for the HEVC codec, are the first step in a series of key enhancements planned for the DVB video encoding specifications. In doing so, DVB intends to continue to provide the “most comprehensive and flexible” set of tools for the delivery of next-generation television services over broadcast and broadband.

HEVC (High Efficiency Video Coding), also known as H.265, is a standard that offers 25% to 50% more data compression at the same level of video quality as its predecessor MPEG-4/AVC. It is already used in several markets around the world. Until now, DVB specifications included HEVC compliance points only for up to 4K resolution.

The updated DVB specification covers the delivery of 8K UHD in both 播送 (transport stream) and wideband (DVB-DASH). The updated documents are the DVB specification for video and audio coding, the DVB-DASH profile for video streaming and the DVB-SI specification for delivery of service information, which will be released over the next few days. The three updates also include some bug fixes.

In the long term, DVB notes that the delivery of 8K video to end users will benefit from “even more efficient” video codecs. To this end, the organization has already launched several initiatives to further explore next-generation video codecs
