8VSB/ASItoASI/CompositeReceiverDecoderCardaG4803
Sencore’s aG4803 is a receiver decoder card
with multiple channel, high-density, multi-
format decoding capabilities. The 8VSB/ASI to
ASI/Composite receiver decoder card enables
providers to receive ATSC broadcast signals
and output those signals via ASI and Composite
Video.
This series of receiver decoder cards are used
within the openGear™ chassis. With the open
architecture of the openGear™ system, the
multi-format decoding functionality of Sencore’s
award winning Modular Receiver Decoder (MRD)
can be easily integrated with a wide range of
solutions available from multiple companies each
specializing in their own technologies.
