Pipeline Control: Allows the user to “ Enable ” or “ Disable ” the transcode.
Input Stream URI: The user can configure the URI Input stream settings: “ Protocol ”, “ IP ”, and “ Port ”. The user must
select the protocol that matches the one used by the receiving equipment. The only available option within this model
is: “ UDP ”.
Decryption Mode: Sets the Decryption mode for transcoding. The only available mode within this model is: Technicolor
COM (AES 128) .
Output Resolution: Sets the output video resolution. Options are “ 480i60 ”, “ 480p30 ”, “ 480p60 ”, “ 720p30 ”, “ 720p60 ”,
“ 1080i60 ”, “ 1080p30 ”.
Output Video Encoding Format: Sets the output video encoding format. The only option available for this model is
“ MPEG-2 ”.
Output Video Bitrate: Sets the output video bitrate in Mbps. Options are “ 3 ” to “ 19 ”, incremented by “ 0.1 ” Mbps.
Output Audio Encoding Format: Sets the output audio encoding format. The only option available for this model is
“ Passthru ".
Output Audio Bitrate: Sets the output audio bitrate. The only option available for this model is “ Same ".
Output Stream URI:
The user can configure the URI Output stream settings: “
Protocol
”, “
IP
”, and “
Port
”. The IP can
be found on the QAM page of the COM's user interface. The Port number is derived from the “ Port ” formula on the
COM's QAM page.
Channel IP and Port: The Overview page lists the output IP and Port for each channel.
EdgeQAM Modulator: The IP address of the COM unit’s QAM modulator. The Clearview 4:2 transcoder must target
this IP in the IP portion of the “Output Stream URI”.
QAM PortBase and Port Formula:
This field indicates the base port to use for placing transcoded streams onto a particular
RF major/minor channel. Take the PortBase value for the RF channel and add the desired subchannel. For example, to
place a transcoded stream onto 23-1, the Output Stream URI port to use would be 16 (PortBase) + 1 (first subchannel
on RF 23). Therefore, use port 17.
Port Formula Example
: If the COM unit’s first RF channel is configured to be 23 and the CV 4:2’s transcoded
output should be placed on 23-1, the CV4:2 transcoder must assigned to port 17 in the Port portion of the
“Output Stream URI”.
Please see Figure 6.2c for details.
