Abstract: A system and method for multimedia data transmission including pooling, by a computer, at least first and second multimedia data streams together in a single channel, wherein each stream defines a respective sequence of frames and each frame includes at least a base layer and at least one enhancement layer; dynamically establishing, by the computer, first and second bit rates respectively associated with the first and second streams; and transmitting, by a transmitter, the at least first and second streams on the channel.

Abstract: A system and method for partitioning a bandwidth of a single channel among plural multimedia streams in a time varying manner. The partitioning is undertaken by dynamically establishing first and second bit rates respectively associated with first and second multimedia streams.

Abstract: A multimedia stream is compressed in parallel by plural encoders, the compressed stream outputs of which are dynamically evaluated for merit. A best one of the compressed streams is transmitted, along with information regarding the particular compression algorithm that was used, so that the receiver's decoder can decompress the stream for presentation.

Abstract: Method and apparatus for detecting cargo state in a delivery vehicle. A method is provided for determining a cargo state in a delivery vehicle. The method includes sensing a cargo state change, and determining whether or not the delivery vehicle is in motion. The method also includes storing the cargo state change if it is determined that the delivery vehicle is not in motion.

Abstract: A communication transaction or use case is broken down into constituent parts having different class of service (COS) requirements. The parts are matched to different links or channels having respective COS characteristics and communicated over the links or channels, and then aggregated at the receiver.

Abstract: Video images in, e.g., a multimedia stream are scanned prior to compression for transmission to recognize symbols, 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: A multimedia data stream is partitioned into two or more parts based on importance, e.g., a first part might represent more significant bits in groups of bits representing pixel colors in a video frame, while a second part might represent the less significant bits in the groups. The more important part of the stream is amplified more than the less important part of the stream.

Abstract: A broadcast multimedia data stream is partitioned into two or more parts based on importance, e.g., a first part might represent more significant bits in groups of bits representing pixel colors in a video frame, while a second part might represent the less significant bits in the groups. The more important part of the stream is error correction coded at a lower rate or using a more powerful coding technique (i.e., with more error correction coding) than is the less important part of the stream.
