signals, the 37-pin micro-D connector allows for up to four stereo pairs, with an
option clock output for synchronization. The remaining channels are only avail-
able as embedded audio in the HD or SD Encoders.
NOTE
The audio cables used in the MPEG-2 Encoder Plus and in the
MPEG-4 AVC Encoder are compatible with this module.
Real-Time MPEG-4 AVC Ultracompression Single-slot Encoders
The single-slot Ultracompression encoders are a denser version of the dual-slot
module, with improved functionality. The advantages for a single-slot encoder are:
•
Fits in a single slot, so 8 of them can be fitted in one iPlex chassis.
•
Improved video quality compared to the dual-slot encoder.
•
Up to 8 stereo audio pairs can be encoded by each card, regardless of encoding mode.
Media Processor (DSP 4PAC) Submodule
The Media Processor, or DSP 4PAC submodule is a high performance, program-
mable platform for the video headend platform. Software is licensable from
TANDBERG Television to give the Media Processor a wide range of functionality,
including MPEG-2 to MPEG-4 AVC Transcoding. The Media (DSP 4PAC) Pro-
cessor Submodule uses four DSPs to give it the performance needed to meet these
applications' demands. And because it is programmable, the Media Processor's
functionality can be changed as your requirements change, reducing future
expenses.
DSP 6-PAC Transrating Submodule
The DSP 6-PAC Transrating Submodule is a plug-in module that provides the per
stream video processing capability needed for rate shaping and rate reduction.
Each DSP submodule provides transrating capability for up to six individual video
programs.
Real-Time MPEG-4 AVC Ultracompression Transcoder
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. This is a dual-slot transcoder.
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.
