CHAPTER 1: INTRODUCTION
The MVD600 is an integrated H.264/AAC Decoder, targeting low-resolution TV-like
broadcast services for mobile receivers via terrestrial transmission.
It receives compressed H.264/AAC data being encapsulated in a MPEG-2 Transport
Stream from a ASI interface. A demultiplexer, together with an automatic program
detection & selection mechanism extracts audio/video data from the bit stream to
the audio/video decoder.
The decoder architecture, consisting of a single video decoder and a dual audio de-
coder allow to decode video simultaneously to two independent audio tracks, to
meet the specific audio requirements (ARIB) in the Japanese market.
Decoded video is formatted for output onto SDI interface. Audio is formatted and
embedded into SDI as well as output directly onto AES interface.
Main building blocks within the MVD600 are an embedded processor module (XS-
cale) and a FPGA with own external memory system, operating as a co-processor.
A real-time Operating System (eCos) allows to perform demultiplexing, audio and
video decoding under real-time constraints in software. Decoded audio and video
frames are stored in FPGA’s memory for formatting, scaling and output, which is
performed by the FPGA.
The firmware of the MVD600 can be updated in the field by software via the Ether-
net port. An operator can control the MVD600 from the front panel or via the RS232
control port from a PC with a terminal program.
Packaged into a stainless steel housing with excellent EMC properties, using a ro-
bust AC/DC converter and forced internal air-flow finally turn the MVD600 into a
reliable solution for broadcast applications.
