To display the video from the air or cable TV video is transmitted in a standardized format SD or HD. In order to reduce the amount of transmitted information used codecs. The H.264 codec is designed for exactly that.
H.264 codec was developed in 2003 for video compression without significant loss of quality (lossy) compressed storage file on the recording medium or transmission to the viewer for viewing on the web. H.264 codec allows to shrink the video standard Full HD and later can transmit compressed video.
HEVC new codec developed in 2013 and its main purpose to compress video formats UHD 4K super high definition, the second designation codec H.265. Why is there such a need, without uzhaty source file codec is difficult to transfer a file on-line over the Internet, connect to 100Mbps that is not enough. Thanks to the new encoding algorithm HEVC codec compresses video 2 times more than the previous H.264 codec
Decipher the notation 2K H.264 60P
- 2K TV decodes video standard 2K (2048x1556)
- TV features an integrated codec H.264, modification under 2K
- 60P, the frame rate is 60 frames per second.
There may be variations 4K, 30 frames per second.
Similarly, you can decrypt and designation codec HEVC.
TV with a screen HD, Full HD and higher, there is a standard H.264 codec, many manufacturers about its presence does not indicate it as a matter of course.
HEVC without it you can not watch video on the TV format 4K UHD and he, too, is the standard codec HEVC have in TV with a screen UHD. The codec can be used not only in the TV, as well as on other devices such as media players.
Example of use HEVC codec media player: video streaming 160Mb second standard 4k enters the decoder which is decoded using the algorithm HEVC video signal 4K 60fps and 10bit color depth is output media player where the content encryption protocol HDCP 2.2 to prevent not authorized video recording and already encrypted signal is output HDMI 2.0
