4.2.3 Egress Configuration
Figure 4-5. Egress Configuration page
The MENCAP 50 Egress Configuration page has the following configurable parameters:
Egress rates
The MENCAP 50 supports egress clock rates from 100 Kbps to 85 Mbps (188-
Byte mode only) in steps of 1 bps (accuracy better than +/- 1 Kbps). The egress
rate may be set up for 204-byte mode, but the egress rate is limited to 67.2 Mbps.
The limitation of 204-byte mode is due to the additional 16-bytes for Reed
Solomon that is included at the end of the frame, resulting in more overhead in
the transport stream.
188-byte/204-byte Framing
The MENCAP 50 supports both 188-byte and 204-byte framing mode. When
selecting 204-byte framing mode, the 16 bytes of the MPEG-2 packet are padded
with zeros (0x00).
