摘要： The present invention relates to a method of and a device for decoding a set of encoded frames at a first resolution (SD) so as to produce a set of output frames at a lower resolution (QCIF). Said device comprises: a partial decoding unit (DECp) for producing a first residual error field at a second resolution lower than the first one and a second residual error field at a third resolution lower than the first one based on the encoded frame; —a first predicting unit (PRED1) for producing a first motion-compensated field based on the first residual error field, on a first reference field (Fix1) and on a second reference field (Fix2); a first adder for combining the first residual error field with the first motioncompensated field so as to obtain a next first reference field (Fiy1); —a second predicting unit (PRED2) for producing a second motion-compensated field based on the second residual error field, on the first reference field and on the second reference field; a second adder for combining the second residual error field with the second motioncompensated field so as to obtain a next second reference field (Fiy2), the next second reference field corresponding to an output frame.

摘要： The invention relates to a method of modifying data in an encoded data signal 125 corresponding to successive pictures divided into sub-pictures, for providing an output modified data signal 126. In particular, this invention can be used for the insertion of an additional data signal 127 into a compressed video signal 125. The proposed schemes according to the invention are based on a transcoder arrangement including at least partial decoding means and partial re-encoding means. This method leads to a cost-effective solution compared to the prior art comprising a minimum number of functional sub-steps, in particular including a unique motion compensation sub-step 205, taking advantage of simplifications and combinations between different sub-steps.

摘要： A switching device SW allows to switch from a first compressed data input stream IS1 to a second compressed data input stream IS2, resulting in a compressed data output stream OS. This switching device comprises a buffer system BS intended to store the data contained in the first and second input streams, and control means CONT which controls the storage of the input streams in the buffer system in order to switch, at a switch request SWR, from the first input stream to the second input stream, using a commutation device COM. A transcoding system TS is intended to receive the data stream at the output of the commutation device and to provide the output stream in a seamless way. The use of a transcoding system allows to avoid an underflow or an overflow of the buffer of the decoder that will have to decode the output stream. Moreover, said transcoding system allows to encode the output stream at a bit rate R, where R may be different from the bit rate R1 of the first input stream and the bit rate R2 of the second input stream.

The method includes selecting a master station, which becomes responsible for building and broadcasting at least one service information table (such as the tables defined in MPEG or DVB), and communicates with the (N−1) to the other stations, known as slave stations, in a limited number of situations corresponding to modifications of the content of the tables and according to a specific table management, where the master station is always in one of three states that are either a waiting state, or a building state, or a transferring state, and specific communication rules for the slave stations and the master station.
