Abstract: Implementations relate to systems and methods for encoding block data to deliver content to a mobile wireless or other device. Content, such as audio, video or textual content, can be generated for broadcast in source blocks that are decomposed into a set of high priority blocks and a set of low priority blocks. Forward error correction is performed on the set of high priority blocks and set of low priority blocks to generate a set of repair symbols for use in reconstructing aggregate transmission blocks of content. The set of low priority blocks and set of repair symbols for a subsequent period can be shifted or inserted into an aggregate transmission block of a prior period. When a request to change channels is received, the decoding of the high priority block corresponding to the content of the new channel can begin before subsequent aggregate transmission blocks are received.
Abstract translation: 实现涉及用于编码块数据以将内容传送到移动无线或其他设备的系统和方法。 可以生成内容，如音频，视频或文本内容，以在源块中广播，这些源块分解为一组高优先级块和一组低优先级块。 对一组高优先级块和一组低优先级块执行前向纠错，以生成一组修复符号，用于重构聚合传输内容块。 用于后续时段的低优先级块集合和修复符号集合可以被移位或插入前一时段的聚合传输块中。 当接收到改变信道的请求时，对应于新信道的内容的高优先级块的解码可以在接收后续的聚合传输块之前开始。

Abstract: Embodiments include systems and methods of improving processing in a decoder in a multimedia transmission system. Multimedia data may include one or more of motion video, audio, still images, or any other suitable type of audio-visual data. One embodiment includes a system and method of parsing fixed and variable length codes from a bit-wise stream of multi-media data by maintaining and reading the data in a processor aligned (e.g., word aligned) way. Another embodiment includes a system and method of decoding variable length codes, particular as received from such a variable length code using multiple levels of decoding tables to speed up decoder table lookup.

Abstract: A method for estimating a feedback channel for a wireless repeater uses frequency domain channel estimation on samples of a pilot signal and samples of a receive signal. The pilot signal samples may be delayed to align the largest channel tap to a given reference time. A time domain feedback channel is generated by retaining both the causal taps and the non-causal taps of the channel estimate.
