摘要： A method and system for improved error resiliency in Internet protocol Television (IPTV) are provided. Received media stream is encoded in a real-time protocol. The RTP media stream is then reordered in a homogeneous arrangement (e.g., video packets together, audio packets together) such that each RTP packet, which contains video contains data from a single video frame. Furthermore, each RTP packet contains a RTP header extension, which specifies the priority of the data. Audio frame and intra-coded frames (I-frames) are marked as highest priority frames, predictably coded frames (P-frames) are marked as high priority frames, bidirectionally coded frames (B-frames) are marked as lower priority frames with anything else occupying the lowest priority. The media stream is forwarded to the plurality of users, in accordance with the priority of each packet. A subscriber's device requests retransmission of any missing packets.

摘要： A controller in a video headend or other transmission element of a signal distribution system is operative to detect a condition in which unicast transmissions of a given content stream to a plurality of terminals meet a specified threshold. The controller starts a multicast transmission of the given content stream in response to the detected condition, and transitions at least one of the terminals to the multicast transmission. In one embodiment, the controller identifies at least one of the terminals as a terminal that will receive the multicast transmission of the given content stream in place of its unicast transmission prior to one or more of the other terminals receiving the multicast transmission. The controller stops the unicast transmission to the identified terminal if that unicast transmission has already been started, starts the multicast transmission, switches the identified terminal to the multicast transmission, and subsequently transitions one or more of the other terminals to the multicast transmission. The identified terminal may be a leading terminal or a trailing terminal.

摘要： A method and apparatus are disclosed for controlling a buffer in a digital audio broadcasting (DAB) communication system. The transmitter predicts the number of encoded frames, Fpred, in the buffer having a limited level and transmits the value, Fpred, to the receiver with the frame. If the transmitter determines that the decoder buffer level is high, the frames being generated by the encoder are small and additional bits are allocated to each frame for each of the N programs. Likewise, if the transmitter determines that the decoder buffer level is becoming low, the frames being generated by the encoder are big and fewer bits are allocated to each frame for each of the N programs. The transmitted predicted buffer level, Fpred, can also be employed to (i) determine when the decoder should commence decoding frames; and (ii) synchronize the transmitter and the receiver clock using feedback depending on the compared level of the decoder to the actual level to Fpred.

摘要： A method and apparatus are disclosed for controlling a buffer in a digital audio broadcasting (DAB) communication system. The decoder buffer level limits are specified in terms of a maximum number of encoded frames (or duration). The transmitter can predict the number of encoded frames, Fpred, in the decoder buffer and transmit the value, Fpred, to the receiver with the audio data. If the transmitter determines that the decoder buffer level is becoming too high, the frames being generated by the encoder are too small and additional bits are allocated to each frame for each of the N programs. Likewise, if the transmitter determines that the decoder buffer level is becoming too low, the frames being generated by the encoder are too big and fewer bits are allocated to each frame for each of the N programs. The transmitted predicted buffer level, Fpred, can also be employed to (i) determine when the decoder should commence decoding frames; and (ii) synchronize the transmitter and the receiver. The receiver fills the decoder buffer until Fpred frames are received before commencing decoding frames when the decoder first starts up or possibly when a new audio program is selected. The transmitter and receiver clocks may be synchronized by adjusting the clock at the receiver by using a feedback loop that compares the actual level of the decoder buffer to the predicted value, Fpred, received from the transmitter (a higher number of encoded frames in the buffer indicates that the clock of the receiver is too slow and should be increased, and a lower number of encoded frames in the buffer indicates that the clock of the receiver is too fast and needs to be slowed down).

摘要： A wireless telephone with record and playback capability is disclosed. The telephone has an operation module, which transmits near-end signals and receives far-end signals, and a record module which writes transmission packets formed from the near-end signals in a first location of a memory and reception packets formed from the far-end signals in a second location of the memory. A playback module reads the transmission packets and the reception packets from the memory, and decodes the transmission packets into transmission speech samples and the reception packets into reception speech samples using transmission and reception decoders, respectively. Further, the playback module has a mixer to mix the transmission speech samples with the reception speech samples to form mixed speech signals for playback on a speaker. The playback module also includes a voice activity detector which outputs a skip signal to the transmission and reception decoders in response to detection of either voice in the transmission speech samples or silence in the reception speech samples. In response to the skip signal, the transmission and reception decoders discard a current transmission packet and a current receive packet and read a next transmission packet and a next reception packet from the memory.
