Video Compression as Fast As Possible
We need to compress video
Video compression technologies are about reducing and removing redundant video data so that a digital video file can be effectively sent over a network and stored on computer disks.Uncompressed video (and audio) data are huge.
The high bit rates that result from the various types of digital video make their transmission through their intended channels very difficult.
Lossy methods have employed since the compression ratio of lossless methods (e.g., Huffman, Arithmetic, LZW) is not high enough for image and video compression, especially when the distribution of pixel values is relatively flat.
The following compression types are commonly used in Video compression:
- Spatial Redundancy Removal - Intraframe coding (JPEG)
- Spatial and Temporal Redundancy Removal - Intraframe and Interframe coding (H.261, MPEG)
