    摘要: Method and apparatus for encoding a protocol data unit (PDU) stream is described. In one example, packets of the PDU stream are outer coded to produce a symbol stream. The symbol stream is formatting to produce trellis groups. The trellis groups are formed into blocks of M×N groups. For each of the blocks, M groups are processed using N trellis encoders to produce N trellis encoder outputs. Each of the N trellis encoder outputs is mapped onto a quadrature amplitude modulation (QAM) constellation to generate N QAM symbol streams. In another example, a single shared trellis encoder is used and channel bond grouping is performed on the encoded QAM symbols.

    摘要: Method and apparatus for using long FEC codes in a content distribution system is described. One aspect of the invention relates to encoding frames of content. Each frame is partitioned into un-coded bits and bits to be encoded. For each frame, an FEC code is applied to the bits to be encoded to generate a codeword. Groups of bits from the codeword are divided among a plurality of channels. Symbols formed from the groups of bits and the un-coded bits are mapped to a constellation for each of the plurality of channels. The symbols are modulated across a respective plurality of bonded channels for transmission.

    摘要: A method and system for enabling trick plays during a variable bit rate (VBR) playback of a media file transmitted to a user media device as a constant bit rate (CBR) flow includes determining a plurality of access points within the media file. The media file is configured to be played back from each of the plurality of access points. A minimum buffer value is calculated for each of the plurality of access points. The minimum buffer value identifies a minimum amount of the media file to transmit to the user media device before beginning playback of the media file from each of the plurality of access points to substantially ensure that the media file is configured to be played back from each of the plurality of access points continuously and uninterruptedly at a variable bit rate.
