H.264 codec is capable of producing compressed video streams with 80 Mb/s bandwidth, limited to 8-bit resolution. Therefore, the number of transmitted pixels is reduced. Compression algorithms that use this method discard low-amplitude, high-frequency components to facilitate signal compression, and thereby reduce bandwidth. The DCT expresses data points in terms of cosine functions at different frequencies. It also utilizes difference coding and is quickly becoming the industry standard for CCTV video compression. It uses interframe predictive coding to reduce video data between a series of frames. ![]() ![]() Like JPEG, MPEG-4, and MPEG-2, H.264 is a discrete cosine transform (DCT)-based codec. H.264 is another name given to MPEG-4 Part 10 and is also known as advanced video coding (AVC). Young, in The Science and Technology of Counterterrorism, 2015 11.16.3 H.264
