SDV TS Redundancy

Hot/Hot and Hot/Warm redundancy selections are the methods available for determining
transport stream failover. Hot/Warm is typically expected to be used for SDV input
streams. Both of these modes use the unicast and/or multicast timeout values to
determine a loss of input stream (loss of input stream determines when a failover to the
secondary occurs).
•
Hot/Hot – a primary and secondary input stream are both opened at the same time.
This means the APEX is receiving twice the amount of input data as it is processing
(primary is received and processed, secondary is received, counted, then discarded).
The APEX monitors both primary and secondary input streams, checking for a loss of
input stream. The unicast and multicast timeout values are used for determining a
loss of input stream. A failover occurs when the Primary input stream is determined
to be missing but the secondary input stream is not missing. Once a failover to a
secondary occurs, there is no mechanism to fallback to the primary.
•
Hot/Warm –only 1 of the redundant input streams is opened at any one time. Either
the primary or secondary input stream is received, but not both. This reduces the
overall amount of input data the APEX is receiving. For this redundancy type, the
APEX uses the unicast or multicast timeout values to determine when to failover. A
failover occurs when the Primary input stream is determined to be missing for the
unicast or multicast timeout period. Once a failover to a secondary occurs, there is
no ability to fallback to the primary.
In both RTSP and MHA modes, the ERM is notified of all loss of input streams and
notified of all failovers to the secondary input stream.
