Channel Setup requires admin-level privileges. Use the options in this section to name and edit output channels, configure IP streaming, channel program guide properties, continuity (default programming that fills gaps), and decoder port properties for any related ProVue Decoders.
To manage channels, click on the Channels option in the Config tab. The application displays the Channel Setup page with a list of all channels on this system, along with the channel Type, Bitrate, and Current Settings for each channel.
Click on the channel name or edit icon to edit a specific Channel.
The application displays the Edit Channel screen.
The following fields are editable. To cancel any unsaved changes and return to the Config page, click the Cancel button at the bottom of the screen.
- Name – Enter a short, descriptive name for the channel.
- Description – Enter a longer description about the channel that will distinguish it from the others at your installation.
- Destination IP Address – This is initially blank or set to a local IP address. Enter the IP address of the device where you want the IP output transport stream to play.
- Destination UDP Port – Enter a port number not used by any other streaming applications that may send networked data to the video server.
- Program Map Table – This feature is for advanced users. Depending on your program map table the files and transport stream sources that play from your server will be remapped to new PIDs and filtered so that certain elements are passed through. Select from several predefined PMT options or make your own in PMT Tables manager, found under Config –> Channels –> PMT Tables.
- Stream Stitching – Normally, the server processes file and stream transitions in the compressed domain to ensure full Transport Stream and Buffer compliance for IP output. Stitched transitions may remove a small number of frames at the end of a transition to ensure buffer compliance. If your system uses TelVue ProVue decoders for baseband output and/or graphics, and you do not require a strictly compliant native IP Transport Stream output, setting streaming stitching to ProVue Optimized will result in tighter, optimized transitions.
- Displays all ProVue Outputs associated with this channel and their formats. If two are displayed, then the output of this channel will be simulcast from both output ports simultaneously.
- Bit Rate – You can select a bitrate standard, or enter your own choice for the bit rate. The bitrate you select or enter is displayed in the box. Files that exceed this rate as their total mux rate cannot be played on the channel. The options you can pick from for a pre-defined bitrate standard include:
- CableLabs SD: 3.75 Mbps
- CableLabs HD: 19 Mbps
- ATSC: 19.396285 Mbps
- Support Variable Mux Rate – Check this box if you want to allow variable mux rate Transport Streams.
- Website Guide Details – Check this box if you want to display the program details link in the automatically-generated website program guide.
- TV Guide Station ID – If your installation submits schedules to TV Guide in X-List format, enter your station ID.
- Enabled – Check this box to configure 2 selected network interfaces to send all IP Output traffic to the destination IP address regardless of routing table rules. To enable NIC Redundancy, exactly 2 interfaces must be selected per channel. NIC Redundancy can be used for applications that require high availability and have redundant streaming paths downstream of the HyperCaster.
- Switch Input – (For systems with a switch) Select a switch input for this channel from the drop-down list, if applicable.
- Switch Output – (For systems with a switch) Select a switch output for this channel from the drop-down list.

When you have finished entering attributes for this channel, click the Save button at the bottom of the section.
Set Multicast TTL
If you are multicasting any of your channels, you can configure the Multicast TTL (Time-To-Live) by going back to the Config Tab –> Channels Section –> IP Multicast TTL.
Enter the number of router hops the system should attempt when forwarding a multicast packet and click the Save button. Entering 0 has the same effect as pressing the Cancel button. The change will take effect next time the server is rebooted.
