The new codec will reduce by half the size of video files at high resolutions


17/08/2012

A new international standard for video compression has been presented today. It was released by the influential expert group Moving Picture Experts Group (MPEG), which met in Stockholm in July. MPEG was established by organizations such as the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC). At the meeting, attended by 450 experts from 26 countries, representing industries such as telecommunications, computers, TV and consumer electronics. The future of these industries depends on the decisions of MPEG, because the standards are of utmost importance.

"Codec High-Efficiency Video Coding (HEVC) was the main topic of the meeting, the results of which were released Draft International Standard, which will significantly increase the compression efficiency compared to AVC, especially for higher resolutions, where the savings are, on average, 50 percent, "- according to the participants of the meeting.

As for video, virtually all digital terrestrial, cable and satellite transmission facilities, video codecs are used that have been standardized group of MPEG. The new standard, released this week, is designed to reduce the load on the transmission media, by reducing the size of video files. Standard High Efficiency Video Coding, will compress the video twice as effective as compared to the current standard of H.264/AVC. It will become available for use in commercial products in the next year.

Most of the new format will benefit mobile networks, where the size is of paramount importance. Telecom operators will be able to provide a wider range of video services than those available today.

"You can halve the bit rate (the amount of data transferred per second) while enjoying the same quality video, or double the number of television channels in the same bandwidth, which will have a huge impact on the industry," - said Per Frodzhd of Ericsson Research.

He was a key figure in this meeting as the chair of the Swedish delegation MPEG. By the nature of its business, Ericsson is working closely with MPEG. Frodzhda Group works with MPEG compression format on the new 3-D video, which will do without 3D glasses. According Frodzhda, this technology can be standardized in 2014.

Another CEO of Ericsson said that the main purpose of his company, is a video compression for mobile telephony.

Of all the data transmitted over networks, most of the accounts for the video. According to statistics obtained from the survey conducted this year, in all countries, the video is a leader in the number of the transmitted traffic for mobile networks, taking share of 50 percent, and in some networks, close to 70 percent.
