    摘要: A method of protecting data with application layer forward error correction in a communication system, wherein the communication system includes first devices with legacy receivers and second devices with FEC-enabled receivers, operation of the legacy receivers is not affected by the application layer forward error correction, and the method includes: determining a duration period; assembling packets of source data into source blocks corresponding to the duration period, each source block comprising a number of packets of source data; encoding the source blocks to generate encoded blocks, each encoded block comprising a number of packets of repair data; and transmitting the packets of repair data.

    摘要: A coding method codes a sequence of digitized images with a plurality of macro blocks in error-prone networks in which case the macro blocks in a section of the image are coded in a first intra-coding mode depending on predetermined criteria. In addition, the macro blocks in a section of the image are coded in a second intra-coding mode or in an inter-coding mode in which case in the inter-coding mode for the macro blocks, movement vectors are selected from the number of accessible reference images. The selection from the number of accessible reference images is limited in such a way that referencing takes place from image areas that were not subjected to the first intra-coding mode at a later stage.

    摘要: A method and corresponding apparatus first encodes digital data by grouping the data into a data segment. A particular length of the data segment is placed into check information encoded within the data segment. The encoded data segments are then transmitted from a first computer to a second computer that receives and decodes the data segments. The second computer decodes the received data segments dependent on the particular length information that was placed in the check information during encoding of the data segment. Decoding dependent upon the particular length information provides dependable synchronization and improved resistance to the introduction of errors, accordingly.
