摘要： For indicating lost segments (LS) across layer boundaries an application encoder (AE) generates independently accessible symbols (Sym) , these symbols (Sym) are aggregated by symbol aggregation means (SA) into a packet payload, the aggregated symbols in the packet payload are transported in a defined packet structure (P1) whereby the packet structure (P1) is defined by anyone of at least one packet header, a block- check sequence, and a payload of variable length of aggregated independent symbols, these packets are transported over a channel by a packet transmitter (PT) segmenting the packets into different segments (S2) by segmentation means (SE), a segment receiver (SR*) included in a first entity has the ability to detect whether a certain segment is lost and also knows the length of the lost segment, the segments are aggregated in the first entity to form at least one packet conforming to the packet stream, the one or more packets are delivered to a packet receiver (CPS) in another, second entity by means of a normalized interface (Nil) between the two entities which allows to pass packets according to the specified format from the first entity to the second entity, a symbol parser entity (CPS) recovers the symbols and passes the individual symbols (Sym) to an application decoder (AR), whereby either correct symbols or erased symbols can be forwarded to the application decoder, the segment receiver (SR*) in the first entity inserts a certain pattern at the position where the lost or defective segment would be which indicates the loss or defect of segment and the length of the lost or defect segment in the aggregated packet, the packet receiver (CPS) in the second entity knows the format, the syntax and the semantics of the inserted pattern, means in the second entity search for specific patterns in the received packet (RP1*) and interpret each found pattern to recover all reliable non-lost information within the packet, and a symbol parser (CPS) in the second entity recovers from the recovered non-lost information of each received packet (RP1*) individual symbols (Sym).

摘要： A determination of indexes allocated to error correcting symbols is provided. Encoded code symbols are generated by means of a generator matrix of a block code from number of source symbols and the encoded transmission errors occur in the received code symbols, the indexes of the error correcting symbols are determined by unambiguously identifying the area of the encoded code symbols by means of first and second parameters, which can be requested in the form of at least one error correcting symbol by the receiving device from the transmitting device for reconstructing the source symbols in an error-free manner.

摘要： Signaling the sending of source blocks within multiple physical layer blocks is done for both streaming and object delivery applications, using minimal additional overhead, and in some cases no overhead, to signal interleaved source blocks within a physical layer block, signaling how symbols are related to the source blocks from which they are generated, and signaled sending and indications of prioritized data for source blocks. Organizing and sending streams over one more channels can be done to improve the quality of delivered streams, while minimizing or improving the needed amount of channel resources and receiver power resources needed.

摘要： There have been proposals to extend the MPE protocol to support different FEC schemes on the MPE layer. Examples of these proposals include: TM-SSP0178 describing a multiburst sliding encoding scheme based on Reed-Solomon (RS) codes, TM-SSP0199r1 describing a block-based encoding scheme based on multi-stage chain reaction (MSCR) codes, and TM-SSP0222 describing a multiburst sliding encoding scheme based on MSCR codes. A framework for harmonizing and integrating those techniques is described herein.

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 of transmitting encoded digital signals and decoding the digital signals at a receiver. During source encoding, the signals are divided into a plurality of subunits. Each subunit is assigned one of a plurality of differing levels of significance. The subunits are hierarchically ordered in a data frame according to their levels of significance. The subunits are then channel encoded utilizing a variable rate code. The rate increases for increasing levels of significance. At the receiver decoder, a subset of the subunits are correctly decoded to produce a correct portion of decoded data. The correct portion is defined by a position of a first error in the data frame. The position of the first error in the data frame is dependent upon at least one of the encoding rate, channel quality, and decoding complexity. The digital signals are then reconstructed using only the correct portion of decoded data.
