Abstract: Methods for adapting the sliding window of sliding window-based error correcting codes based on the coding structure of a compressed media stream are disclosed. In one aspect, a sender packetizes each frame of a media stream to be sent to a receiver into a set of frame packets. The sender also determines compression dependence of each frame and adapts a sliding window of a sliding window-based error correcting code based on the compression dependence of the frame. The sender encodes the frame packets into at least one associated parity packet according to the error correcting code with the adapted sliding window, and sends the frame packets and the at least one associated parity packet to the receiver.

Abstract: A powerful new class of methods for encoding digital data for reliable transmission over unreliable communication channels is described. With this method, the message bits are divided into multiple submessages and the bits in each layer are encoded using a standard error correction code to provide a plurality of subcodewords. A first linear transformation is applied to each of the subcodewords. The so-transformed subcodewords from the different submessages are then combined to form a first redundancy block to be transmitted. Additional redundancy blocks are generated by repeating this process on the same message but with jointly related nonidentical sets of linear transformations. The result is a set of codewords for each message which are then used to generate a transmitted waveform in one of several different ways, depending upon the application.

A first resource that is available to transmit a page is selected at the base station and the page transmitted from the base station via the first resource. The page is received at the user terminal via the first resource and a second resource that is available to transmit a page response is selected at the user terminal.
