H.264 is an industry standard for video compression, the process of converting digital video into a format that takes up less storage when it is stored or transmitted.
Video compression or video coding is an essential feature for applications such as CCTV Camera, digital television, DVD and Blu-Ray disks, mobile TV, video conferencing and internet video streaming. Standardising video compression makes it possible for products from different manufacturer encoders, decoders and storage media to inter-operate. An encoder converts video into a compressed format and a decoder converts compressed video back into an uncompressed format.
