Coded Elementary Stream
Overview
The compressed output streams from the module are in the form of MPEG-2 transport
packets that have been encapsulated into a transport stream packet.
Supported Profiles
The SD/HD MPM1 Transcoder supports the following profiles:

Output Bit Rate
The output rate of the transport packets is derived from the 27 MHz reference clock and is
accurate to within 1 kbps of the configured transport bit rate.
The output video bit rate of the MPM is configurable within ranges dictated by the operating
mode. These ranges are listed in the MPM1 Feature Summary page. The configured video
rate means the transport stream rate.
The module supports bit-stuffing to maintain configured bit rate if the operating mode
requires it.
The output of a module never exceeds the configured bit rate (or bit rate ceiling).
