Patent number: 7693188Abstract: A method and system are provided for remultiplexing program bearing data. The remultiplexing method and system are applicable to MPEG-2 compliant transport streams carrying video programs. Remultiplexing functions may be distributed across a network. The remultiplexer can furthermore optimize the bandwidth of transport streams by replacing null transport packets with transport packet data to be inserted into the output transport stream. Remultiplexing and program specific information can be seamlessly dynamically varied without stopping, or introducing a discontinuity in, the flow-of outputted transport packets.Type: GrantFiled: November 3, 2003Date of Patent: April 6, 2010Assignee: Ericsson Television Inc.Inventors: Robert Robinett, Regis Gratacap, William Slattery

Patent number: 7620073Abstract: An apparatus comprising an input capable of receiving a bandwidth optimized transport stream is provided. The bandwidth optimized transport stream can be produced by receiving a transport stream of variably compressed program data bearing transport packets and one or more null transport packets. One or more of the null transport packets is selectively replaced with another to-be-remultiplexed non-null data bearing transport packet. Independently of determining an amount of information carried by a program data bearing transport packets from time to time in the received transport stream, at least one selected program bearing transport packet is scheduled for output in an output remultiplexed bitstream.Type: GrantFiled: December 9, 2004Date of Patent: November 17, 2009Assignee: Tandberg Television Inc.Inventors: Robert Robinett, Regis Gratacap

Publication number: 20050105486Abstract: A method and system are provided for remultiplexing program bearing data. The remultiplexing method and system are applicable to MPEG-2 compliant transport streams carrying video programs. A descriptor based system is used for scheduling the timely output of transport packets wherein each descriptor records a dispatch time as well as a receipt time for each transport packet. The receipt time is used for estimating program clock reference adjustments, but final program clock reference adjustment is performed in hardware in relation to the precise output timing of each transport packets. A descriptor and transport packet caching technique is used for decoupling the synchronous receipt and transmission of transport packets from any asynchronous processing performed thereon. The descriptors can also be used for managing scrambling and descrambling control words (encryption and decryption keys). Remultiplexing functions may be distributed across a network.Type: ApplicationFiled: December 9, 2004Publication date: May 19, 2005Inventors: Robert Robinett, Regis Gratacap
