Decoding


In principle the MPEG standard defines only a data format and the directly associated functionality of the decoder. The implementation of the encoder is free and offers a wide range of options to achieve the best possible quality depending on the available computer power and time.


The actual MPEG coding represents a process with strongly asynchronous characteristics. Real time conditions can be achieved only by extensive dimensioning of the encoder components or alternatively by quality losses.


The selection of the procedures have a determining influence on the necessary decoding power. For prediction and interpolation the reference pictures have to be accessible within the memory.
