Template management¶
Templates in Catena SE are the main way to define shared processing rules for TV channels: transcoding, archive (DVR), authorization, segmentation settings for HLS and DASH protocols, and so on. A template has no per-channel settings for the source (Input) or multicast push (Push) — those are set on the channel. You configure “how to process” once in the template and apply it to multiple channels.
The steps are:
- Create a template
- Configure transcoder and archive in it
- Create a channel, set its source and select this template
- Confirm on the channel list that the channel has transcoder and archive
1. Create a template¶
Go to the Templates section. Enter the template name (e.g. tv) and click the create button.
After creation, the template edit page opens.
2. Configure transcoder and archive¶
On the Transcoder tab, enable the transcoder and add video tracks (e.g. 1080p, 720p, 360p with the desired bitrates). You do not need to save yet.
On the Archive (DVR) tab, enable archive recording and set the retention period (e.g. number of days) if needed. Click Save.
3. Create a channel with this template¶
Go to the Channels section and create a new channel (e.g. template-demo). On the Inputs tab, add a source — e.g. multicast udp://239.0.10.1:1234. On the Basic tab, select the template you created (tv) in the template field. Save the channel.
The channel inherits transcoder and archive from the template; the source and other per-channel settings are defined on the channel itself.
4. Channel list: transcoder and archive¶
Return to the channel list. For a channel using a template with transcoder and archive, the list shows the corresponding indicators (transcoder, archive).
