Abstract: A radio communication system includes a primary station which is arranged to transmit a series of data packets to a secondary station which operates according to an ARQ scheme for acknowledging correct reception of each packet. The primary station transmits error correction information relating to any packets that are not received correctly, thereby enabling the secondary station to extract correctly the data. The data packets are transmitted via a plurality of logical channels, so that an error in transmission of one packet does not hold up transmission of packets in other channels. Transfer of data transmission from one primary station to another is done by transferring each channel when correct reception of a data packet on that channel has been acknowledged, thereby avoiding the extra signaling required in transferring logical channels in which a data packet has been received in error and the error correction transmissions have not been completed.

Abstract: A video compression process speeds the optimal choice of quantizers for compressing a data stream by setting up the optimization problem as a path-optimization problem in configuration space and finding the lowest cost path through the configuration space. The process begins with a starting node (or “state”) and propagates least-cost waves through the space until a path is completed to the end. The process may continue using uncompleted paths while their costs are less than the end state, beginning with the lowest cost incomplete path, until an improved path is found. The process may further continue, for a time constrained process, until time runs out or all useful possibilities are exhausted.

Abstract: An interpreter uses a symbol table containing information for resolving symbolic references in instructions. Memory is provided for storing symbolic reference-result associations, the result of the association having resulted from resolving the symbolic reference of the association for an instruction. The memory is organized in groups of locations, each for results for a different category of instructions. During execution of a particular instruction, that group is consulted which is assigned to the category to which the particular instruction belongs. If that group contains an association for the symbolic reference in the particular instruction. If there is such an association, the result from the association is used as operand data for executing the particular instruction. If there is no such association, the particular symbolic reference is resolved by means of the symbol table.

Abstract: An integrated circuit accesses first encrypted data stored in an external random access memory and accesses second encrypted data stored in an external read-only memory. The external random access memory and the external read-only memory are external to the integrated circuit. When accessing a first portion of the first encrypted data stored in the external random access memory, a first algorithm is used to decrypt the first portion of the first encrypted data. When accessing a first portion of the second encrypted data stored in the external read-only memory, a second algorithm is used to decrypt the first portion of the second encrypted data. The second algorithm is different than the first algorithm.

Abstract: A recording apparatus includes quality test and feedback features for recording speech information of a dictation and subsequently transfers the recorded speech information to a speech recognition device for off-line speech recognition. A recorder records speech information in a recording mode. A transfer unit transfers recorded speech information to the speech recognition device in a transfer mode. The speech recognition device recognizes text information to be assigned to the transferred speech information, the quality of recognized text information depending on the quality of the received speech information. A speech quality tester tests whether the quality of the speech information received in the recording mode is sufficient for obtaining a predefined quality of the recognized text information when the speech information is processed by the speech recognition device.

Abstract: The present invention relates to a device for processing blocks of coded data included in a sequence of coded digital images (ES) according to a block-based coding technique, said device comprising a post-processing circuit DFD (33). Such a device effectively corrects the blocking artifacts while minimizing the bandwidth used, the decoder directly transmitting decoded data blocks (B) to the post-processing circuit. In addition, such a device introduces no or little drift during the decoding since the decoder continues to use reference images (RB) during a motion compensation step. This is because the reference images are no longer the decoded images but the completely processed images as the post-processing circuit is situated in the decoding loop.
