RGB Networks and Tandberg Television have jointly launched an advanced integrated ad insertion solution which enables telecoms carriers seamlessly insert local ads into high-definition MPEG-4 AVC video programs
The solution features RGB's carrier-class Modular Video Processor (MVP) which performs frame-accurate ad splicing into MPEG-4 AVC streams encoded by Tandberg EN8090 series MPEG-4 AVC HD encoder.
Television programming and broadcast movies are increasingly being delivered in the popular MPEG-4 AVC format which offers tremendous bandwidth advantages compared to MPEG-2, particularly for HD programming. Splicing MPEG-4 AVC encoded transport streams is not the same as splicing MPEG-2 streams due to the more complex MPEG-4 AVC encoding structure. This requires intelligent video processing by the encoder and the splicer to support seamless frame-accurate ad insertion at the splicer.
Working as an integrated solution, the Tandberg EN8090 encoder adds the SCTE-35 cue tones to the MPEG-4 AVC programs which are then detected by the MVP and used to seamlessly and accurately insert local ads into the programs. Seamless and accurate splicing is a critical aspect of the ad insertion process, without which ad spots can run short or overlap the broadcast content, causing serious consequences, such as picture freezes from buffering problems at the set-top box level.
