    Abstract: Techniques for transmitting overhead information to facilitate efficient reception of individual data streams are described. A base station may transmit multiple data streams on multiple data channels (or MLCs). The MLCs may be transmitted at different times and on different frequency subbands. The time-frequency location of each MLC may change over time. The overhead information indicates the time-frequency location of each MLC and may be sent as "composite" and "embedded" overhead information. The composite overhead information indicates the time-frequency locations of all MLCs and is sent periodically in each super-frame. A wireless device receives the composite overhead information, determines the time-frequency location of each MLC of interest, and receives each MLC at the indicated time-frequency location. The embedded overhead information for each MLC indicates the time-frequency location of that MLC in the next super-frame and is transmitted along with the payload of the MLC in the current super-frame.

    Abstract translation: 描述了用于发送开销信息以促进单个数据流的有效接收的技术。 基站可以在多个数据信道(或MLC)上发送多个数据流。 MLC可以在不同的时间和在不同的频率子带上传输。 每个MLC的时间 - 频率位置可能随时间而变化。 开销信息指示每个MLC的时间 - 频率位置,并且可以作为“复合”和“嵌入”开销信息发送。 复合开销信息表示所有MLC的时间 - 频率位置,并且在每个超帧中周期性地发送。 无线设备接收复合开销信息,确定感兴趣的每个MLC的时间 - 频率位置,并且在指定的时间 - 频率位置接收每个MLC。 每个MLC的嵌入式开销信息指示该MLC在下一个超帧中的时间 - 频率位置,并与当前超帧中的MLC的有效载荷一起发送。

    Abstract: Video images in, e.g., a multimedia stream (12) are scanned (14) prior to compression (16) for transmission to recognize symbols (17), such as graphics symbols and alpha-numeric characters. The types, positions, sizes, etc. of the symbols are recorded to render symbol information, and then the images are compressed with or without compressing the symbols, which may be removed from the images prior to compression if desired. The compressed video and symbol information are sent to a receiver, which decompresses the video, optionally transforms the symbols, and then inserts the symbols where indicated by the symbol information.

    Abstract translation: 在压缩(16)之前扫描(例如)多媒体流(12)中的视频图像以传输以识别诸如图形符号和字母数字字符的符号(17)。 记录符号的类型,位置,大小等以呈现符号信息,然后在压缩之前利用或不压缩符号来压缩图像,如果需要,可以在压缩之前从图像中去除图像。 压缩的视频和符号信息被发送到解码视频的接收机,可选地转换符号,然后插入由符号信息指示的符号。
