摘要： An audio system comprises an audio source terminal 11 and a audio playback terminal 13, connected to each another by a wireless data link 14. The source terminal 11 comprises a source computer 15, and a cellular modem 17. The playback terminal 13 comprises a playback computer 19 having an internal processor 23 and an audio processor 24. Connected to the processor 23 is a cellular modem 21, an audio transducer 25, and a user control 27. Data relating to audio components, representing different services, is stored at the source terminal 11 where it is spatially processed and transmitted to the playback terminal. At the same time, each individual audio component is transmitted at a lower bit-rate than the spatially processed data, to the audio source terminal 11, whereafter it is spatially processed. Although the low bit-rate transmission causes a loss of audio quality, the positional data remains unaffected. Accordingly, when played, the combination of a high quality signal with low three-dimensional audio positional accuracy, and a set of low quality signals with high three-dimensional audio positional accuracy, results in restoration of the human perception of three-dimensional position to the degraded three-dimensional audio signal.

摘要： Logical connections between nodes in a network can be established by the following steps: generation of an identifier by each group of logically connected nodes in the network; exchange of identifiers between physically connected groups of logically connected nodes; and establishment of logical connections between physically connected groups of logically connected nodes for which the exchanged identifiers differ. Repeatedly carried out, these steps can allow a network without logical loops to be built up from individual nodes.

摘要： A method and apparatus is provided for connecting an optical source to a multimode optical fibre in a multimode optical fibre communications system. A single mode fibre length is provided such that optical radiation admitted from an optical source at one end of the single mode fibre length is provided to a multimode optical fibre at the other end of the single mode fibre length. This method and apparatus is used in a duplex patchcord for connecting an optical transceiver to a pair of installed multimode fibres. The second fibre in the patchcord is a multimode fibre for passing optical signals to the optical receiver of the transceiver.

摘要： Three-level (ternary) line codes are provided for use in transmitting binary data at high data rates (e.g. 100 Mbits/s) over twisted-pair cable, without producing excessive radiated emissions at frequencies above 30 MHz. A running digital sum (RDS) is computed for a stream of ternary symbols as it is encoded; if this RDS reaches a predetermined limit, the polarity of the next following non-zero symbol is determined so as to change the RDS towards zero. In addition, if the binary data stream and the RDS satisfy another predetermined criterion, such as the RDS having a particular polarity when two or more 0 symbols have occurred, then the next non-zero symbol is determined so as to have the opposite polarity; otherwise the next non-zero symbol has the opposite polarity to the preceding non-zero symbol. The RDS limit and the predetermined criterion can be selected to obtain a desired power spectral density for the ternary signal propagating over the twisted-pair cable.

摘要： Codeword synchronization and scrambler synchronization in a block-coded serial communications link are accomplished by (i) substituting a specific comma control codeword for a selected codeword value occurring in the output of a scrambler receiving an input data stream, and (ii) using selected polarity-independent bits of the block-coded scrambled bit stream to convey samples of the scrambler state. Inversion of received control codewords indicates polarity inversion somewhere along the link, enabling automatic polarity correction to be applied.

摘要： In a method for encoding payload bits for transmission over communications link, data and control information are assembled into n-bit data words, where n is an even number and words for control information are constrained to have zero disparity (equal numbers of binary zero and one digits). The n-bit data words are then encoded into n+2-bit code words by adding a two-bit label; for words carrying control information the label has a value of 10. For other data words the disparity is evaluated; if it is zero, the label bits are 01; if the disparity is non-zero and opposite in sense to the running digital sum of the code words transmitted already, the label bits are 11; otherwise, the data word is inverted, and the label bits are 00.
