Ericsson has developed a new video codecs called High Efficiency Video Coding (HEVC) or H.265 which is claimed to use only half the bit rate of the currently used video standard H.264( which accounts for almost 80% of the internet video). Video codecs are used in the digital world to encode data for transmission and decode it for playback.
High Efficiency Video Coding (HEVC)
The current generations electronic devices like Smartphones, Tablets, Televisions displays etc comes with a very high resolution which requires high internet bandwidth to get the full capability of the display while watching videos on the internet. To stream a video in next generation 4K displays(with 4K resolution) it requires 4 times the bandwidth compared to bandwidth required to watch Full-HD video.
With the upcoming video codec High Efficiency Video Coding (HEVC) or H.265 it is possible to watch a Full-HD video with the same bandwidth which is required for watching a HD video in H.264 format. Also this format can support video resolution upto 8K(8192×4320).
Once this format comes into standard, it will become possible to see high quality videos with less bandwidth and which in-turn means it requires less hard disk space for storage.
