MPEG Layer
The MPEG-2/DVB layer is specified in ISO/IEC IS 13818 “Generic Coding of Moving
Pictures and Associated Audio”. The main functionality of this layer is to transform
MPTS (Multi-Program Transport Streams) into a number of SPTS (Single-Program
Transport Streams). A transport stream carrying multiple programs is in this way
split into a number of ‘mini’ transport streams, each carrying a single program. This
ensures that the video can be passed through limited bandwidth links such as ADSL
further down the transmission path.
