New H.266 twice as efficient as H.265! (The Sequel Thread)

Video data is expected to account for over 82 percent of the global Internet traffic by 2022, and with the proliferation of 4K and 360-degree video, better video codecs are needed to reduce the bandwidth and space requirements of your favorite content. That's where Versatile Video Coding (VVC) comes in, which is able to achieve the same subjective quality as HEVC at only half the bitrate.

The Moving Pictures Expert Group has three different video codecs lined up for release this year: Low Complexity Enhancement Video Coding (LCEVC), Essential Video Coding (EVC), and Versatile Video Coding (VVC).

The first is part of the MPEG-5 standard and is designed for live streaming on services like YouTube and Twitch. To that end, LCEVC acts as an add-on codec that takes an existing one like AVC or HEVC and improves the encoding speed. It does so by taking a base image encoded at a lower resolution and adding detail and sharpness by combining that with two layers of encoded residuals. Preliminary tests also showed improvements in decoding efficiency, which could lead to better battery life on mobile devices.

I have been around for a long time, now it is h266 before that h265 before that h264.... On internet forums (and I don't mean you) every new generation armchair video experts pretend it will make a big difference.

like the article you posted says "is able to achieve the same subjective quality as HEVC at only half the bitrate." it is never about improving PQ/AQ but making files/bitrate smaller when you allow to lose some quality. It is good for streaming companies (less costs) but meaningless for consumers since we pay for content not bits.

Hmmm Visually lossless. Now we have another marketing spin.

I never heard of compression being involved where something doesn't becomes artificial.

MPEG Founder Declares ‘Death’ of Standard

And yet, the signal sent out by OTA TV stations is still MPEG-2. AND some are still 720p.

I don't understand how, in 2020, that's still "a thing." It baffles me.

Those are the specs for ATSC 1.0.

ATSC 3.0 is just coming on line. No tuners in TVs though or external tuners yet. Will be an unveiling at CES 2021

Real easy, H.262 is specified by ATSC 1.0, that is the codec used by all tuners and TV sets that meet the ATSC 1.0 specs. The H.262 decoders are built into silicon therefore can not be changed.

ATSC 3.0 has these codecs:

• H.265/MPEG-H HEVC
• H.264/MPEG-4 AVC
• H.262/MPEG-2 Part 2
• VC-1
• AVS

ATSC 3.0 is voluntary by the broadcaster so who knows when and how many will upgrade from 1.0 to 3.0. Map here.

SiliconDust may have one out soon, some info here.

Qualcomm Expects to Deploy VVC in 2021

SAN DIEGO—Qualcomm has said it expects to begin commercial deployment of the new Versatile Video Coding standard next year.

The new standard, which was finalized last week, will be able to efficiently transport high-resolution content, such as 4K or 8K media, through mobile networks. It also supports HDR content and 360-degree videos.

“By 2022, 82% of internet traffic will be video. In our connected world of Netflix, Zoom calls and video sharing, video compression is an extraordinarily important technology area that people around the world rely on every day,” said Marta Karczewicz, vice president of technology, Qualcomm Technologies.

“Qualcomm Technologies is extremely proud of the great work our inventors and engineers have done in creating the core technologies that went into the VVC standard and driving the standard to completion in the middle of a global pandemic,” added Jim Thompson, executive vice president, engineering and chief technology officer, Qualcomm Technologies, Inc.

“Qualcomm is an IP leader across so many different fields of technologies that facilitate people’s connected experiences on a daily basis. We change the way the world connects, computes, and communicates, and we’re excited to enable the new possibilities of video streaming VVC offers the world.”
