Abstract: Systems, devices and processes reduce the amount of memory or disk space needed to store encoded video content used in adaptive video streaming by eliminating certain portions of the recorded program from one or more copies of the encoded program. Content occurring before or after a scheduled start of a program, for example, can be retained in only a subset of the encoded copies so that the program content is available to be streamed, but only at certain video qualities. Commercials or other less popular portions may also be eliminated in one or more encoded copies. By eliminating the less-likely-to-be-viewed portions of the content from some (but not all) of the encoded copies, the total amount of storage space needed to store the encoded program is reduced without compromising the ability to play back all portions of the recorded program.

Abstract: Original transmitters of television broadcast content, such as national broadcasters, may tunnel various data such as SCTE-35 messages through a special closed captioning service before handoff to their local affiliates. The tunneled SCTE-35 messages may thus survive the re-encoding of both the local broadcaster to an over-the-air (OTA) retransmission, and re-encoding by any subsequent cable or satellite television providers as well. An uplink center and television service provider (e.g., a cable or satellite system) may receive the transport stream from the local broadcaster, may strip out the tunneled SCTE-35 messages from extra closed captioning streams at the uplink, re-create the SCTE-35, and then process it at the uplink of the satellite system, for example, by performing ad insertion, re-muxing the SCTE-35 for the satellite broadcast, and/or modifying it and sending it over the satellite broadcast on a separate PID to the set top boxes for those STBs for ad insertion.
