Abstract: There is provided a network device comprising at least one processor, and a memory storing instructions which when executed by the at least one processor configure the processor to perform a method. The method comprises segmenting packets of an original data stream into at least two partial data streams, and transmitting the at least two partial data streams to a downstream receiver configured to consolidate the at least two partial data streams based on the sequence numbers of the original data stream to reconstruct the original data stream. Each of the at least two partial data streams has an identifier in a header. The at least two partial data streams maintain sequence numbers of the original data stream.

Abstract: The present invention provides systems and methods for providing on-demand datacasting. A system according to an exemplary embodiment of the present invention comprises a rate generator for controlling the rate at which data signals are combined with audio/video signals. The system may also include a system controller for controlling the rate of the rate generator. The system controller may also monitor the complexity of the audio/video signals, calculate an average complexity of the audio/video signals, calculate an average complexity of the audio/video signals and determine whether the average complexity is greater than the typical complexity of audio/video signals. The system controller may adjust the rate of the rate generator based on the determination of whether the average complexity of the audio/video signals is greater than the typical complexity of audio/video signals.

Abstract: A temporally-pipelined predictive encoder/decoder circuit for encoding or decoding an input signal containing a sequence of data frames received at a particular frame rate and frame data rate into an output signal having an equal frame rate employs a plurality of N predictive encoders/decoders. An input buffer may be used to extract the information for each data frame in the input signal and supply such information to a corresponding one of the encoders/decoders at rate of 1/N of the particular frame data rate. Each encoder/decoder generates corresponding encoded/decoded information as it is received as well as provides digitized frame information to the encoder/decoder processing the next received image frame. The encoded/decoded information is provided to corresponding frame buffers which temporarily store such information.
