Abstract
Encoding a real-time and non-real-time video stream, encapsulating the encoded video stream along with the decoding software corresponding to the encoding program into active packets at the Application and Services layer, and transmitting active the packets to the receiving terminal, which then supplies the receiver with the necessary decoding software to play any type of encoded video stream without having the associated decoding software pre-loaded.
Claims11
A method for transieving a compressed data file from a transmitter to a receiver, said method comprising the steps of
- determining at the transmitter a decoding program for the compressed data file,
- independently partitioning at the transmitter the compressed data file into data sub-files and the decoding program into decoding sub-programs,
- propagating from the transmitter to the receiver a sequence of the sub-files and the sub-programs,
- detecting at the receiver the sequence to determine the sub-files and the sub-programs, and
- at the receiver combining the sub-files to reproduce the compressed data file and combining the sub-programs to reproduce the decoding program.
A system for transceiving a compressed data file over a path, said system comprising
- a transmitter including
- an encoder deducer for determining a decoding program for the compressed data file,
- partitioning means, coupled to the encoder deducer, for independently partitioning the compressed data file into data sub-files and the decoding program into decoding sub-programs, and
- propagating means, coupled to the partitioning means and the encoder deducer, for generating and propagating onto the path a sequence of active packets composed of the sub-files and the sub-programs, and
- a receiver including
- a detector, coupled to the path, for detecting the active packets to determine the sub-files and the sub-programs,
- combiner means, responsive to the detector, for combining the sub-files to reproduce the compressed data file and combining the sub-programs to reproduce the decoding program, and
- a decoder, coupled to the combiner means, for decoding the reproduced compressed data file with reproduced decoding program.
