Video compression refers to reducing the quantity of data used to represent digital video images, and is a combination of spatial image compression and temporal motion compensation. Video compression is an example of the concept of source coding in Information theory. This article deals with its applications: compressed video can effectively reduce the bandwidth required to transmit video via terrestrial broadcast, via cable TV, or via satellite TV services. Most video compression is lossy — it

Scalable Video Coding (SVC) is the name given to an extension, Annex G, of the H.264/MPEG 4 AVC video compression standard. H.264/MPEG 4 AVC was developed jointly by ITU T and ISO/IEC JTC 1. These two groups created the Joint Video Team (JVT) to develop the H.264/MPEG 4 AVC standard. The objective of the SVC standardization has been to enable the encoding of a high quality video bitstream that contains one or more subset bitstreams that can themselves be decoded with a complexity and

There are two different video file formats known as Flash Video: FLV and F4V. The audio and video data within FLV files are encoded in the same way as they are within SWF files. The latter F4V file format is based on the ISO base media file format and is supported starting with Flash Player 9 update 3. Both formats are

Adobe Flash (formerly Macromedia Flash) is a multimedia platform used to add animation, video, and interactivity to Web pages. Flash is frequently used for advertisements and games.

A videophone is a telephone with a video screen, and is capable of full duplex (bi directional) video and audio transmissions for communication between people in real time. It was the first form of videotelephony, later to be followed by videoconferencing, webcams, and finally telepresence. At the dawn of the technology, videotelephony also included image phones which would exchange still images between units every few seconds over conventional POTS type telephone lines, essentially the same as

A container or wrapper format is a meta file format whose specification describes how data and metadata are stored (not coded). A program able to identify and open a container file might not be able to decode the contained data. This may be caused by the opening program lacking the required decoding algorithm, or the meta data not providing enough information. By definition, a container format could wrap any kind of data. Though there are some examples of such file formats (e.g. Microsoft
