Typical bit rates — Embedded Audio
The VN-Matrix 300 supports the transport of the Ancillary data that is embedded in the
video transport.
The ancillary data contains audio, timecode, closed caption and other user specific
information. The VN-Matrix 300 supports the transport of audio data only.
Audio overview:
z Available in blocks of 4 channels.
z Audio Bit rate
z
For HD and 3G sources, the audio bit rate is approximately 4 Mbs for each channel
in the group. The total bit rate for each group is approximately 16 Mbs.
z
For SD sources, the audio bit rate is approximately 2 Mbs for each channel in the
group. The total bit rate for each group is approximately 8 Mbs.
z
Forward error correction may be applied to correct the network problem.
z
FEC is required to correct for packet drops on the network.
z
FEC is only added to Audio only
z
Implements the recommendations defined of PRO-MPEG COP3
z
FEC can add up to 50% bit rate overhead.
