While a joint collaboration team on video encoding (JCT-VC) is working hard to define the specifications of the standard, Bievres, France-based ATEME unveils a prototype HEVC encoder at IBC 2012 held here in Amsterdam, the Netherlands.
During the demonstration, ATEME, a video compression solution provider, compresses 4K image data using its HEVC encoder and transmit them at an average data bit rate of 15 megabit per second, 15Mbps.
“We are putting new algorithm for the same code, said Aboobucker-Siddique MouhamadSald, support technician with ATEME
According to him, the show floor demo shows that the 4K video images of 3840 x 2160p are shot by Sony’s famous F65 4K camera, or RED’s 4K Epic camera in a 60 Hz frame rate and then are being encoded in CBR, or constant bit rate mode with ATEME’s HEV encoder machine.
The encoded and compressed 4K image date is transmitted from a broadcasting server all the way through a home set-top-box to Toshiba’s native 4K TV at a speed of between 11 and 17 Mbps, or megabit per second.
HEVC is one of the most crucial technology building blocks, which the TV industry thinks is the most instrumental in bringing the 4K TV era closer to reality.
As the 4K picture carry more than 8 million pixel information, however they will for sure threaten to strain the current broadcasting and IP network bandwidth to the limit, resulting in bandwidth crunch.
Were it been for a new generation of compression technology like HEVC or AVC Ultra, there will be few network bandwidth available to accommodate the bandwidth-guzzling 4K pixel bitmaps.
The standard setting body JCT-VC stipulates that the HEVC should double the data compression ratio, compared with H.264, the most prevalent compression technology for 2K full HD images.
The measure of the data compression ratio is usually defined in the data bit rate of Mbps, or megabit per second. The lower the data rate is, the better the compression ratio is. The well-known MPEG2 boasts a date rate of 20Mbps.
ATEME is scheduling the rollout of HEVC encoder for Oct. 2013.
