Of specialised instruction sets to provide the bit manipulations Software-based MPEG-2 players, which usually require the support The various types of MPEG-2 decoder may be broadly classified For non-realtime, converting stored analogue / digital clips into an MPEG-2 video clip library, less expensive (but slower) equipment may be used. For real-time transmission, such as encoding the output of a video camera, this may necessitate expensive equipment. The ability to maintain picture quality with rapidly moving scenes and complex pictures will depend upon the algorithms and processing power of the encoder. There are many options when encoding a video picture into an MPEG-2 bit stream. In many ways, the encoder is the key item.
