Unicast Source Filter:
This control allows the user to enable or disable Unicast Source filtering. This
control works similar to IGMP v3 SSM.
Unicast Source IP Address:
This control allows the user to enter a source IP address of a unicast
stream. The decoder will not accept the input unless the source IP matches in the unicast stream (if
enabled).
Unicast Source UDP Port Number:
This control allows the user to also filter by the UDP port of the
incoming unicast stream. The decoder will not accept the input unless the UDP port matches in the
unicast stream (if enabled).
Manual PID Control
Video PID:
This parameter allows the user to set the Video Packet ID (PID). The video PID allows
the decoder to sort the video packets in the transport stream to organize them for output.
PCR PID:
This parameter displays the Packet ID of the Program Clock Reference (PCR) of the
program being output. The value of the PCR is used to generate a system timing clock in the
decoder. This clock provides a highly accurate time base that is used to synchronize audio and video
elementary streams.
Private Data PID:
This parameter displays the control data output PID. Private/control data can be
sent directly to 3080UEP-H264HD-IPASI control IP Port, the data is then captured and embedded
into the encoder output on a Private Data PID. The 7882DEC can extract data from this Private Data
PID and output it as a UDP packet on its own control port.
VANC PID <1-4>:
This parameter allows the user to specify the SMPTE2038 PID. This PID is
required to reconstruct Vertical Ancillary data from the SMPTE2038.
Audio PID <1-8>:
This parameter allows the user to set the Audio Packet ID (PID) for the associated
audio stream.
