Mpeg 2 what is it

Because the MPEG-2 standard provides good compression using standard algorithms, it has become the standard for digital TV.

It has the following features:. The list of systems which now or will soon use MPEG-2 is extensive and continuously growing: digital TV cable, satellite and terrestrial broadcast , Video on Demand, Digital Versatile Disc DVD , personal computing, card payment, test and measurement, etc. This is known as interaction, and is seen by many as the key discriminator between traditional video and MPEG At the moment, nobody is quite sure whether, when everything falls into place, the bulk of users will interact through their TV s or their Personal Computers - and exactly how much interaction the users want or will pay for.

The Moving Picture Coding Experts Group was established in January with the mandate to develop standards for coded representation of moving pictures, audio and their combination. The MPEG-2 standard has been extended by various groups including:. The MPEG-2 video compression algorithm achieves very high rates of compression by exploiting the redundancy in video information.

MPEG-2 removes both the temporal redundancy and spatial redundancy which are present in motion video. Temporal redundancy arises when successive frames of video display images of the same scene.

MPEG-4, on the other hand, utilizes its high rate of compression and smaller file sizes to provide high-quality video and audio across mobile networks.

MPEG2 uses a simple algorithm for compression of files and provides a superior image quality. For the compression of videos, MPEG2 discards the information in portions so that the image frame does not change. Then it only saves the portion where any new information is included. Thus, it has a straightforward algorithm in comparison to MPEG4. This was the time when the internet was picking up speed. Online videos were emerging, and the streaming of videos through the internet became popular.

MPEG2 was not compatible with portable devices, and thus, a need for a better standard came up. It was a format that was compatible with portable devices like mobile phones. It was also suitable for media players.

This is because of its sophisticated algorithm, unlike MPEG2. This also allows it to be a more versatile format as compared to MPEG2. MPEG4 provides the additional advantage of compressing the file in a way that the file size reduces.
