METHOD AND APPARATUS FOR PROVIDING A DYNAMIC ERROR RECOVERY MECHANISM FOR TRANSMITTING MEDIA OBJECTS, METHOD AND APPARATUS FOR SEQUENTIALLY ASSIGNING A CONTROL PACKET TO A PLURALITY OF DATA PACKETS CORRESPONDING TO A MEDIA OBJECT, AND APPARATUS FOR DETERMINING TRANSMISSION ERRORS IN A BROADCAST ARCHITECTURE

摘要

A system and apparatus for assigning a sequential control packet (in a sequential series) to a group of MPEG-2 compliant program packets for error recovery of a media object. The invention parses the media object into a series of program packets (204, 206) for transmission via a transport stream. A control packet (202) is then inserted into the transport stream as to correspond to a quantity of program packets, where a counter (220) of the control packet (202) is sequentially numbered. An additional control packet (210) is interleaved in the transport stream after a second quantity of program packets are parsed. Optionally, the control packets are received by a receiving device that issues a command in response to missing control packet, when there is a gap in the sequential numbering of received control packets.
