Zusammenfassung:A video encoding system in which pixel data is decomposed into frequency bands prior to encoding. The frequency bands are organized into blocks that are provided to a block-based encoder that encodesthe blocks and passes the encoded blocks to a wireless interface that packetizes the blocks for transmittal over a wireless connection. The encoder may categorize the encoded frequency bands into multiple priority levels, and may tag each frequency block with metadata indicating the frequency band represented in the block, the priority of the frequency band, and timing information. The wireless interface may then transmit or drop packets according to the priority levels of the encoded frequency blocks in the packets and/or according to the timing information of the frequency blocks in the packets. 本发明公开了一种视频编码系统,其中在编码之前将像素数据分解成频带。该频带被组织成块,该块提供给基于块的编码器,该基于块的编码器对该块进行编码并将所编码的块传递到无线接口,该无线接口对该块进行分组以通过无线连接进行传输。该编码器可将所编码的频带分类为多个优先级级别,并且可用指示该块中表示的该频带、该频带的该优先级和定时信息的元数据来标记每个频率块。然后,该无线接口可根据该分组中的所编码频率块的该优先级级别和/或根据该分组中的该频率块的该定
