iPlex Installation and Hardware Specification Guide
The DSP 6-PAC Transrating Submodule provides the per stream video processing
capability needed for rate shaping and rate reduction. Each DSP 6PACsubmodule
provides transrating capability for up to six individual video programs: each 6PAC
hosts 6 transrator input ports and 6 transrator output ports. Because there are no
cable connections or indicators required, the DSP 6PAC submodule requires a
blank faceplate.

The MPEG-4 AVC Ultracompression Transcoder provides real-time transcoding
from MPEG-2 to H.264. H.264 Video provides a better quality as well as 40-60%
lower bitrates compared to MPEG-2. The transcoder also provides full live video
compression up to HD.
The MPEG-4 AVC Ultracompression Transcoder accepts both SD and HD Video
Format inputs. It provides six Audio channels and Dual Mono Split with a repli-
cated channel. The Codec transitions between the two channels seamlessly (except
possibly for a signal level discontinuity) and without a restart.
Video stream is always transcoded. Audio streams in the input program can be
selected for pass-through or transcoding. For transcoding, either two stereo pairs
or one 5.1 channel is supported.
The output of MPEG-4 AVC Ultracompression Transcoder contains two pro-
grams:
•
The first program contains the main video and all the transcoded audio streams and passed
through streams. The program number for the first program is the same as the program
number of the input source.
•
The second program contains the PIP video. The PIP program number is one plus the main
program number. The PMT PID for PIP is dynamically generated to be a unique one.
