In-stream controls for national video distribution
Systems and methods are described for delivering regional content for a lineup over a national network. A content provider may select a particular regional broadcast for inclusion in a regional service lineup. The content provider may be able to broadcast multiple, or even all, services nationally. At regional distribution centers, a multiplexer may select only those services that are desired for the region in response to in-stream signals. In some instances, a single region-specific version of a given service may be selected from multiple versions broadcasted nationally. The regional lineup, including the selected services, can then be multiplexed and transmitted to customers throughout the region.
1. A method comprising:
receiving, by a first multiplexer, a plurality of alternative video feeds for a single slot in a regional service lineup, wherein each alternative video feed of the plurality of alternative video feeds comprises multiplexing instructions indicating whether that alternative video feed is to be multiplexed in the regional service lineup;
determining, by the first multiplexer and based on the multiplexing instructions, a first alternative video feed of the plurality of alternative video feeds for inclusion in the regional service lineup; and
transmitting, by the first multiplexer, the regional service lineup comprising the determined first alternative video feed.
2. The method of claim 1 , wherein the regional service lineup comprises:
one of the plurality of alternative video feeds and a plurality of other video feeds.
3. The method of claim 1 , further comprising:
monitoring the determining of the first alternative video feed; and
storing a description of the monitoring in a log.
4. The method of claim 1 , wherein the plurality of alternative video feeds comprise Internet Protocol feeds, and wherein transmitting the regional service lineup further comprises transmitting via quadrature amplitude modulation (QAM).
5. The method of claim 1 , wherein the multiplexing instructions comprise in-stream messaging, the method further comprising:
selecting, based on the determining, the first alternative video feed for inclusion in the regional service lineup.
6. The method of claim 5 , wherein the in-stream messaging comprises a Society of Cable Telecommunications Engineers (SCTE) 35 protocol command.
7. The method of claim 6 , wherein determining the first alternative video feed comprises comparing a region identifier provided by a scheduler with the SCTE 35 protocol command.
8. The method of claim 7 , wherein the first alternative video feed has a constant bitrate less than or equal to a minimum bitrate of another video feed of the plurality of alternative video feeds with a variable bit rate.
9. A method comprising:
determining, by a computing device, a plurality of broadcasts for a single slot in a regional service lineup, wherein each of the broadcasts corresponds to one of a plurality of geographic regions;
inserting, by the computing device, codes into the plurality of broadcasts, the codes configured to instruct a multiplexer to select one or more broadcasts from among the plurality of broadcasts for inclusion in the regional service lineup in one of the plurality of geographic regions corresponding to the multiplexer; and
transmitting, by the computing device, the selected one or more broadcasts of the plurality of broadcasts.
10. The method of claim 9 , wherein the regional service lineup comprises:
one of the plurality of determined broadcasts and a plurality of other broadcasts.
11. The method of claim 9 , further comprising:
monitoring the determining of the plurality of broadcasts in real time; and
storing a description of the monitoring in a log.
12. The method of claim 9 , wherein the plurality of broadcasts comprise Internet Protocol feeds, and wherein transmitting the regional service lineup further comprises transmitting via quadrature amplitude modulation (QAM).
13. The method of claim 9 , wherein the codes comprise in-stream messaging, the method further comprising:
selecting, based on the codes, the one or more broadcasts for inclusion in the regional service lineup.
14. The method of claim 13 , wherein the in-stream messaging conforms to Society of Cable Telecommunications Engineers (SCTE) 35 protocols.
15. The method of claim 14 ,
wherein the inserting codes comprises inserting a region identifier in the in-stream messaging.
16. The method of claim 15 , wherein:
one of the plurality of determined broadcasts has a constant bitrate less than or equal to a minimum bitrate of another broadcast of the plurality of determined broadcasts with a variable bitrate.
17. A method comprising:
receiving, by at least one signal inserter, a plurality of alternative video feeds for a single slot in a service lineup; and
inserting, by the at least one signal inserter and based on an instruction from a scheduler, in-stream signaling into the plurality of alternative video feeds to cause at least one multiplexer to determine content based on the in-stream signaling.
18. The method of claim 17 , wherein the instruction from the scheduler comprises an Event Signaling and Messaging (ESAM) instruction, and
wherein the in-stream signaling comprises Society of Cable Telecommunications Engineers (SCTE) 35 protocols.
19. The method of claim 17 , further comprising determining, by the scheduler, a schedule and a database of downstream devices, wherein the downstream devices comprise the at least one signal inserter and the at least one multiplexer.
20. The method of claim 17 , wherein the inserting comprises inserting a region identifier in the in-stream signaling.
