Video Over IP

Video Over IP



Video Over IP makes it possible to access up-to-the-second images at any time from any computer or any Video supported IP phones anywhere. The Internet can be used as the carrier for the information.



With VoIP, calls are converted into packets of data. The packets travel like any other type of data, such as e-mail, over the public Internet and/or any private Internet Protocol (IP) network.

Video Over IP systems use a standard video codec to compress video content to a bitstream and then use an IP network to deliver that bitstream over network infrastructure in a stream of IP packets. Modern codec standards such as H.264 (MPEG-4 Part 10) enable compression of standard definition (SD, or broadcast quality) and high definition (HD) video at over 50% gains in compression efficiency over earlier standards such as MPEG-2.



Video Over IP Codecs



H.263:- H.263 is a video compression standard originally designed as a low-bitrate compressed format for videoconferencing. It was developed by the ITU-T Video Coding Experts Group (VCEG) .



H.264:- H.264 is an emerging video coding standard proposed by the Joint Video Team (JVT). The new standard is aimed at high-quality coding of video contents at very low bit-rates. H.264 uses the same hybrid block-based motion compensation and transform coding model as some existing standards, such as H.263and MPEG-4 .



IP video simplifies and consolidates video storage media, making video data available for retrieval and transmission from any location on the network and viewable in a standard media player on a PC or any IP phone that supports video call with a decoder attached.
