TSB
- The Media Server requests the DVR Manager to share a TSB corresponding to a SourceId, if no TSB is available the QAM Source is queried for an instance with the same SourceId.
- DVR manager creates a TSB ID along with DVR Sink and connects the QAM Sources to the DVR Sink.
- DVR manager shares the QAM Source instance with the media server.
- Media Server connects the QAM Source to the HN Sink, the media data goes through from Media Server to the Media Client device.
- A TSB is a recording with a special property called maximum duration. When maximum duration reached during TSB, a sliding time window will be applied for recording.
- The clear SPTS from QAM Source is AES encrypted by the DVR sink before it’s saved in the HDD.
