Efficient Chroma Intra Prediction in H.266/VVC

Let’s talk about Efficient Chroma Intra Prediction

As an expert in video compression technologies, I understand the importance of efficient chroma intra prediction in the context of H.266/VVC (High Efficiency Video Coding/ Versatile Video Coding). Chroma intra prediction plays a crucial role in reducing redundancy within video frames, leading to better compression ratios without compromising visual quality. By leveraging predictive coding techniques specifically tailored for chroma components, H.266/VVC aims to significantly improve video compression efficiency compared to its predecessors.

Chroma intra prediction involves predicting the chroma (color) components of a video frame based on neighboring pixels within the same frame. Unlike inter prediction, which utilizes motion estimation to predict future frames, intra prediction relies solely on information contained within the current frame. This makes it particularly important for achieving high compression efficiency in scenarios where inter-frame prediction is not feasible or effective, such as still scenes or sudden scene changes.

The Importance of Chroma Intra Prediction in Video Compression

Efficient chroma intra prediction is crucial for achieving substantial bitrate savings in video compression. By accurately predicting chroma components, redundant information can be efficiently removed, resulting in smaller encoded video streams without perceptible loss of quality. This is especially significant for applications with bandwidth constraints, such as streaming services, where minimizing data transfer without sacrificing visual fidelity is paramount.

H.266 / VVC codec approved for 4K and 8K video compression

H.266 / VVC codec approved for 4K and 8K video compression

H.266 / VVC codec approved for 4K and 8K video compression
The Fraunhofer Institute for Telecommunications has announced the approval of a new video codec.

H.266 / VVC was developed with the need for ultra-high definition content in mind and is intended to be the successor to the popular H.264 / AVC and H.265 / HEVC standards, used by more than 10 billion devices. to handle more than 90% of the global video volume.

H.266 / VVC (Versatile Video Coding) provides highly efficient transmission and storage of all screen resolutions (from SD and HD to 4K and 8K), supports High Dynamic Range (HDR) video and video 360 degree panoramic … Supports YCbCr color space with 4: 4: 4 and 4: 2: 2 color conversions, color depth from 8 to 16 bpc, and auxiliary channels for data such as depth and transparency.

It is claimed that compared to H.265 (HEVC), the new standard will demonstrate a significant increase in compression ratio and allow a 50% lower bit rate to be used for streaming video with the same quality. For example, if a 90 minute video in UHD quality in H.265 required 10 GB of data transfer, then H.266 will fit in 5 GB while maintaining the same quality level. In comparison, the AV1 format in terms of compression efficiency outperforms HEVC by an average of 17% (at a high bit rate by 30-43%).

The standard has been created for 5 years by the MPEG (ISO / IEC JTC 1) and VCEG (ITU-T) working groups with the participation of Apple, Ericsson, Intel, Huawei, Microsoft, Qualcomm and Sony. The MC-IF (Media Encoding Industry Forum) was established to license overlapping patents, with more than 30 companies and organizations owning the intellectual property used in H.266 / VVC.

The cost of increasing compression efficiency is a significant complication of algorithms, leading to increased computational resource requirements (up to 10 times for encoding and up to 2 times for decoding compared to H.265). Unlike the AV1 video encoding format, the use of H.266 / VVC in your products requires a royalty fee. A reference implementation of an encoder and decoder for H.266 / VVC is expected to be released in the fall.

New standard for digital video compression twice as efficient as HEVC

New standard for digital video compression twice as efficient as HEVC

German engineers who once developed the popular MPEG-3 audio coding format, as well as AVC and HEVC, which allowed video to be compressed to fit on a smartphone, announced a new standard for VVC compression, which could become a critical element in the era of ultra high definition video.

Compressed video today represents 80% of global Internet traffic. New standard presented by the Institute of Telecommunications. Fraunhofer, provides improved compression that will reduce file size by 50% compared to the older H.265 / High Efficiency Video Coding (HEVC) format. In other words, the H.266 / VVC standard will provide faster file transfers with the same quality. It supports all video resolutions from SD and HD to 4K and 8K, high dynamic range video, and 360-degree video.

“Today it is increasingly difficult to distinguish a voice robot from a human”
By reducing data requirements, VVC is making video streaming over mobile networks more efficient, according to the Institute’s website.

For example, if HEVC required approximately 10GB of data for 90 minutes of UHD recording, then with VVC you only need 5GB while maintaining the same quality. The new format is especially suitable for 4K and 8K broadcasts on flat screen televisions.
As with each of the previous protocols, VVC will require new encoding chips that are already in development. Apparently this is being done by the Institute’s partners: Apple, Ericsson, Intel, Huawei, Microsoft, Qualcomm and Sony.

To avoid previous licensing problems, the developers will authorize the use of the new standard on FRAND principles (fair, reasonable and non-discriminatory use), which will be enforced by the Media Coding Industry Forum (MC-IF). The first VVC-compliant encoding program will be released this fall.

H.266 / VVC (video compression standard)

VVC (H.266) CODEC

A new standard for video compression without quality loss appeared
On July 7, 2020, the Fraunhofer Heinrich Hertz Institute research organization introduced a new video compression standard: H.266 / VVC. The codec created will reduce the size of video files in half, while ensuring fast data transfer between devices.

H.266 CODEC

Fraunhofer HHI explained that the new solution focuses on efficient data compression while maintaining original quality. The codec is capable of performing tasks twice as efficiently as the HEVC solution, which was introduced in 2013. The codec does an excellent job of handling ultra high definition video (4K, 8K, 360 degree video) as well as with more common formats (480p, HD (720p) and FullHD (1080p)).

A new video compression standard has been released. The size is reduced by half without loss of quality.
For example, the HEVC codec above would require 10GB for 90-minute long UHD video. The VVC codec will compress video down to just 5GB. H.266 / VVC is also well suited for text, graphics encoding, the solution supports adaptive resolution switching, 10-bit and HDR. H.266 / VVC was developed in partnership with Apple, Intel, Huawei, Ericsson, Qualcomm, Sony, and Microsoft.

Fraunhofer HHI intends to create a uniform licensing model for patents related to basic codecs, adhering to the FRAND principle (“fair, reasonable and non-discriminatory”). Fraunhofer HHI will present a list of the first applications that support encoding and decoding using the H.266 / VVC standard in Autumn 2020. It is assumed that before 2021-2022, hardware solutions that support the new standard, although chip development aimed at accelerating H.266 at the hardware level is actively underway by July 2020.

New H.266 / VVC codec will cut video file sizes in half without losing quality

New H.266 / VVC codec will cut video file sizes in half without losing quality

H. 266 VVC

According to analyst estimates, compressed video data today represents up to 80% of all global Internet traffic, and software developers pay close attention to the quality of processing and transmission of “heavy” content on mobile networks. Germany’s Fraunhofer Institute for Telecommunications has introduced a new video encoding standard: according to the developers, it can cut the amount of transmitted data in half without losing image quality.

H. 266 (VVC)

The codec, whose specification spans more than 500 pages, was created with the popularity of streaming video in 4K and 8K resolutions in mind. It took specialists several years to develop it together with Apple, Ericsson, Intel, HUAWEI, Microsoft, Qualcomm and Sony. The new compression standard is called Versatile Video Coding. It promises to reduce the bit rate and size of video files by about 50% without a noticeable difference in image quality compared to its predecessor (H.265).

H.266 / VVC, according to its creators, makes video transmission on mobile networks more efficient. For example, the old standard requires approximately 10 GB of data to transfer 90 minutes of 4K video, while using the new technology only requires 5 GB of bandwidth. In addition, the codec is suitable for all types of moving images, including 360-degree panoramas and screen capture with live simulcast. Other benefits of H.266 include adaptive resolution switching, as well as support for HDR and 10-bit color depth.

Based on preliminary test results, the efficiency of the new codec turned out to be superior to that of the previously introduced AV1, which was competing with H.265 due to open source code and the lack of a licensing system. Additionally, H.266 has shown significant bitrate savings compared to HEVC, especially when it comes to 4K content. The first software solutions capable of taking advantage of VVC encoding and decoding are expected to appear this fall.

New H.266 codec – same quality, half the file size

New H.266 codec – same quality, half the file size

H.266 Codec

Fraunhofer’s company HHI, which created the H.264 and H.265 video codecs, without which today it is difficult to imagine the production of video content, has introduced an updated video encoding algorithm: H.266. The company didn’t get smart with the names and just added one, but under the hood we’re waiting for changes that they’ve been asking for for a long time, that is, the new codec provides half the amount of data while maintaining image quality. at the level of previous codecs.

After its completion, it means H.266 standard to halve the video size | Eg24 News

Video resolution and bitrate are growing day by day, today you will not surprise anyone, for example, with the ability to shoot 4K, rather you will surprise with the absence of such a mode, 8K is on the way, and then scary Think about it, since terabytes of data snowballs, you only have time to swap out the hard drives …

The image does not demonstrate the capabilities of the codec, just an image for a change 🙂

The industry needs a new video encoding algorithm and the H.266 codec came in handy. This algorithm is also called Versatile Video Coding (VVC), that is, a universal video codec. The new standard provides improved compression, reducing the amount of data by approximately 50% while increasing the data transfer rate by the same amount as the previous H.265 (HEVC) standard. Most importantly, without sacrificing image quality.

The H.266 / VVC codec allows you to work with video in all resolutions, from SD and HD up to 4K and 8K, it supports video with high dynamic range and omni-directional 360 ° video, which, although in small steps, continues to gain popularity among users.

Fraunhofer HHI spent more than three years working on the codec, and the description of the H.266 / VVC standard has more than 500 pages of small text, and industry monsters like Microsoft, Apple, Sony, and Intel participated in the work. Benjamin Bross, director of Video Coding Systems, called the launch of the new codec a “quantum leap in encoding efficiency.”

In its press release, Fraunhofer HHI says that while a 90-minute video encoded in H.265 / HEVC is about 10GB, the same video with the new codec will only take up 5GB, and this is the same image quality. “Since H.266 / VVC was designed with ultra-high definition video content in mind, the new standard is especially useful for 4K and 8K video transmission,” the press release says. Also, the codec will support all formats from 480p onwards.

Some experts predict the imminent decline of the era of dominance of the JPEG standard for photographs. So the HEIF image compression format, which Apple implemented on the iPhone, is based on the H.265 / HEVC codec and is used, for example, in the new Canon 1D X Mark III SLR camera. In the same way, the widespread adoption of the H.266 / VVC codec may well lead to the popularization of the “VIC” format for photographs.

The H.265 (HEVC) standard has started to gain popularity recently, and the main problem of its use was quickly clarified: the amount of data that needs to be transferred in some way, stored somewhere, and processed in some multi-core processor systems. Processor and storage manufacturers are, of course, delighted, but the introduction of the new format is quite timely, obvious, and expected by many users and developers alike.

The implementation process itself depends on the hardware manufacturers that could record data using the new codec and on the software manufacturers that could process this highly recorded data. Experts predict the emergence of a new codec by the end of 2020. This process can be greatly accelerated, as recently online streaming has gained particular popularity, and no one will refuse to stream high-quality, high-bit-rate videos, for example, 8K or 4K, and at high speed.

H.266 / VVC video format introduced: same quality as H.265 / HEVC when compressed 2x

H.266 / VVC video format introduced: same quality as H.265 / HEVC when compressed 2x

The Fraunhofer Institute fo H.266 r Integrated Circuits in Germany, which developed the popular MP3 (MPEG-1 Layer 3) audio encoding format, as well as AVC and HEVC, announced a new video compression format: H.266 / VVC, or Encoding. versatile video player. Someday it should completely replace the current H.265 / HEVC.

H.266

The new H.266 claims twice the video stream compression efficiency with the same level of quality as H.265. As noted in the institute, in the case of 90 minute 4K video when using the H.265 / HEVC codec, approximately 10GB of data will need to be transferred, while H.266 / VVC provides identical video quality with half the volume of data.

“By reducing the [volume of] data requirements, H.266 / VVC makes video transmission on mobile networks (with limited traffic) more efficient. For example, the H.265 / HEVC standard above requires approximately 10GB of data for 90 minutes of recording in UHD resolution. The new H.266 / VVC will require only 5 GB while maintaining the same quality, ”said the Institute.

The Institute highlights that the new standard has been developed specifically for 4K (3840 × 2160) and 8K (7680 × 4320) ultra-high definition video, and is especially suitable for transmitting the corresponding signal to flat-screen televisions. The Institute also calls H.266 / VVC the “ideal solution” for all types of moving images, from high-resolution 360-degree panoramic images to screen sharing.

The most widely used codec now is H.264 / AVC, although the H.265 / HEVC standard has been around for quite some time. To avoid previous licensing problems, the developers will authorize the use of the new standard under FRAND (fair, reasonable and non-discriminatory terms), which the Media Coding Industry Forum (MC-IF) will enforce. The first VVC-compliant encoding program will be released in the fall. Hopefully the new H.266 / VVC will not follow the same fate as H.265 / HEVC and will be accepted by the market faster.
