Introduction
The BBG-1090-TRX-MPEG has the following features:
•
Multi-Standard transcoder (MPEG-2 and H.264), with support for both SD (Standard
Definition) and HD (High Definition) content. Up to 4 simultaneous transcoding
instances are supported per board.
•
Resolution resizing support.
•
Audio pass-through support.
•
Audio transcoding support: MPEG-1 Layer II, AAC-LC and Dolby AC-3 inputs, and
MPEG-1 Layer II and AAC-LC outputs.
•
2 ASI input ports and 2 ASI output ports. All ports support the full ASI line rate of 213
Mb/s.
•
2 Ethernet ports with 100/1000 Mb/s support, capable of transmitting and receiving at
line rate.
•
Up to 8 simultaneous transmit and receive streams per Ethernet port.
•
RTP support for Ethernet transmission/reception
•
Advanced redundancy features.
•
Internal program replication – individual programs can be routed to multiple outputs.
•
Internal MPTS (Multi-Program Transport Stream) multiplexing and demultiplexing.
•
(P)SI parsing and generation; ATSC table parsing.
•
MPTS to SPTS Splitting support.
Typical application scenarios for the unit are:
•
Contribution and Distribution: optimizing legacy MPEG-2 equipment for backhaul
transmission.
•
IPTV ingest of legacy content.
•
IP and ASI protection switching.
Product Overview
The core of the unit is a switch that can select individual programs from transport stream inputs
and connect these programs to transport stream outputs. This switch works as an intelligent
demultiplexer for transport stream inputs, and an intelligent multiplexer for transport stream
outputs. Additionally, individual programs can be routed to one of 4 transcoder instances to be
processed prior to being connected to an output. A transcoder instance can change the
compression format (between MPEG-2 and H.264), the bit rate, frame rate, and/or resolution of
the stream, as well as change the audio compression format and bit rate.
The following inputs are available:
