SYSTEM AND METHOD FOR INTELLIGENT PACKET REPLACEMENT FOR MOTION PICTURE EXPERT GROUP TRANSPORT STREAM SPLICING

摘要

An apparatus to splice MPEG transport streams in a communications network comprises an input to receive a first transport stream and a storage unit storing a second transport stream. A packet replacement module is coupled to the input and the storage unit. The packet replacement module receives the first transport stream from the input and the second transport stream from the storage unit and categorizes the packets into a first packet type and a second packet type and storing them into a buffer. The packet replacement module replaces packets of the first packet type from the first transport stream with packets of the first packet type from the second transport stream and replaces packets of the second packet type from the first transport stream with packets of the second packet type from the second transport stream, producing a spliced transport stream.

1. An apparatus to splice MPEG transport streams in a communications network, the apparatus comprising:
an input to receive a first transport stream comprising packets; a storage unit storing therein a second transport stream comprising packets; a packet replacement module coupled to the input and the storage unit, the packet replacement module receiving the first transport stream from the input and the second transport stream from the storage unit, the packet replacement module categorizing packets from the first transport stream and the second transport stream into a first packet type and a second packet type and storing them into a buffer; the packet replacement module replacing packets of the first packet type from the first transport stream with packets of the first packet type from the second transport stream, and replacing packets of the second packet type from the first transport stream with packets of the second packet type from the second transport stream wherein the first transport stream and the second transport stream are merged into a spliced transport stream.
