MPEG-1 is a standard for lossy compression of video and audio. The standard consists of the following five Parts :     . The basic architecture established in H. Fourteen video and fourteen audio codec proposals were submitted by individual companies and institutions for evaluation. The codecs were extensively tested for computational complexity and subjective human perceived quality, at data rates of 1.

This archiving tool offers excellent compression performance and functionality for handling several audio files as one archived file. Test results show that its compression performance, in terms of compression ratio and required processing time, is much better than that of ZIP when the input data is audio files. Other recent standardization activities are also briefly mentioned.
The intent of the H. This was achieved with features such as a reduced-complexity integer discrete cosine transform integer DCT ,    variable block-size segmentation, and multi-picture inter-picture prediction. The H. A specific decoder decodes at least one, but not necessarily all profiles. The final drafting work on the first version of the standard was completed in May , and various extensions of its capabilities have been added in subsequent editions. A license covering most but not all patents essential to H. The commercial use of patented H.
Video encoding standards. Recall that without compression, the raw video would require an upload speed of 3 Gbps— or Mbps. Video compression or video coding is an essential technology for applications such as digital television, DVD-Video, mobile TV, videoconferencing and internet video streaming. The distribution of digital video content over computer networks has become commonplace. In comparison, H.
Save Digg Del. MPEG-2 video compression is the de facto standard for entertainment video. MPEG-2 video compression is popular for a number of reasons:.
Digital images or video are compressed primarily for two reasons: to save storage space for archival, and to save bandwidth in communication, which saves time required to send the data. A compressed digital image or video can be drastically smaller than its original size and saves a great deal of storage space. Upon retrieval, the data can be decompressed to get back the original image or video. When one needs to transmit the data through a channel of a certain bandwidth, the smaller data size also saves transmission time. There are many different compression algorithms , each with its own characteristics and performance.
