Abstract: A method and apparatus for flexibly and reliably processing one or more MPEG signals from at least one source. The method provides for synchronizing (28) decoded streams (36) to a reference clock, for playing multiple streams simultaneously or for transitioning (24) between streams in a seamless manner. The output streams can have varying formats and can include both video and audio. The structure and method further provide for the capability of skipping B frames to reach a desired reference frame quickly and to edit the MPEG streams regardless of GOP size.

Abstract: Disclosed is a device and method for finding the sync pattern in a fixed-length packetized bitstream (e.g. an MPEG2 transport stream). The device comprises means for accumulating a histogram of occurences of the sync pattern, and identifies the start of a packet depending on said histogram. An embodiment comprises a match table which is addressed by modulo-K counter (K is number of bytes in packet). Upon receiving a sync pattern, the corresponding table entry is incremented, otherwise the entry is set to zero or remains unaffected (faster embodiment). As soon as a table entry acquires a predetermined number N, a packet start signal is issued.

Abstract: A client device (100) receives a first set of one or more segments of streamed content in a unicast transmission mode. Further, the client device (100) receives a synchronization stream indicating, separately from the streamed content, a timing of segments of the streamed content transmitted in a multicast transmission mode. Based on the indicated timing, the client device (100) controls switching to receiving a second set of one or more segments of the streamed content transmitted in the multicast transmission mode.

Abstract: A method is provided for delivering a streaming media asset to a client device. For the method, a request is received over a communication network from a client device for playing a media asset in accordance with a streaming media technique. Prior to fully authorizing the client device to play the media asset, the client device is provided with access to a first cryptographic key that decrypts a subset of the media asset so that the client device is able to render the subset of the media asset before completion of the authorization. The subset of the media asset is less than all of the media asset. Subsequent to successfully fully authorizing the client device to play the media asset, the client is provided with access to at least one additional cryptographic key that decrypts a remainder of the media asset.

Abstract: A video or multimedia distribution system receives multiple video streams and transcodes them into a single stream of UDP packets with each of the plurality of video data packets for respective ones of the video streams being assigned a port number corresponding to the respective video stream. The UDP packets are routed to a plurality of Access Points (APs) for transmission. A User Equipment (UE) communicates with the APs and selects one of the video streams for viewing on the UE by selecting the port number corresponding to the desired video stream. A first processor in the UE identifies and stores UDP packet data having the selected port number and a second processor retrieves and plays the video stream on a display. The UE can "change channels" to view other video streams by changing the port number to the port number of the desired video stream.

Abstract: An aircraft in-flight entertainment system includes a plurality of seat electronic units (SEUs) that are daisy chained through a packet data network (PDN) loop to a content server containing media content. The SEU includes a power supply, a communication switch, a processor, a communication interface, and a power control circuit. The power supply supplies power to the communication switch, the processor, and the communication interface. The communication switch selectively routes packets containing media content through the processor and the communication interface to the video display unit, or through a segment of the PDN loop to a downstream electronic unit. The power control circuit responds to the power supply supplying less than a threshold level of power by supplying power to the communication switch from the segment of the PDN loop connected to the upstream electronic unit and/or the downstream electronic unit.
