Abstract: Transmission system for transmitting and receiving, and subband encoding methods for generating for transmission, digital signals containing modulated bit allocation information; and record carriers containing such a signal. The transmission system include a transmitter which encodes in accordance with the subband encoding method a wide-band digital signal into subband signals which are each made up of successive signal blocks having a predetermined number of samples of that subband signal. The samples in the signal blocks of the subband signals are quantized to produce quantized samples in the signal blocks, and bit allocation information denoting how many bits the samples in the signal blocks are to be quantized by is generated. The bit allocation information (or a portion thereof) is modulated to obtain modulated bit allocation information.

Abstract: Transmission system, and transmitter and receiver for use in the transmission system for transmitting and receiving digital signals containing modulated bit allocation information. The transmitter encodes a wide-band digital signal into subband signals which are each made up of successive signal blocks having a predetermined number of samples of that subband signal. The samples in the signal blocks of the subband signals are quantized to produce quantized samples in the signal blocks, and bit allocation information denoting how many bits the samples in the signal blocks are to be quantized by is generated. The bit allocation information (or a portion thereof) is modulated to obtain modulated bit allocation information. The quantized samples in the signal blocks and the modulated bit allocation information are included in a digital signal applied by the transmitter to a transmission medium. The receiver receives a replica of the digital signal applied to the transmission medium.

Abstract: A device for reproducing music includes a non-volatile memory for storing, for two or more magnetic record carriers (2), a start position signal for a favorite piece of music on each one of these record carriers. The device further including an address signal generator (29) for generating an address signal in conformity with the record carrier inserted into the device, and an operating circuit (39) for generating an activation signal upon operation of the operating circuit. If a user has listened to a record carrier, an FTP mode can be switched on by operating the operating circuit (37), while the memory (25) is adapted to supply the start position signal at an output (37) in response to the address signal, the start position signal being stored in the memory for this one piece of music on the record carrier inserted into the device.

Abstract: When recording n pieces of music on a magnetic record carrier (3), two groups of pieces of music are formed. A first group of g.sub.1 pieces of music is recorded on the A-side of the record carrier and a second group of g.sub.2 (=n-g.sub.1) pieces of music is recorded on the B-side. The groups are selected such that the total time duration of each of the two groups T.sub.tot (g.sub.1), T.sub.tot (g.sub.2) is nearest to half the total time duration of all the n pieces of music (T.sub.tot /2).

Abstract: A cassette comprises a housing which accommodates a magnetic tape partly wound on two reel hubs. A main wall of the housing has two openings which are coaxial with the reel hubs to allow the passage of reel spindles of a drive apparatus. The cassette further comprises a slide cover for covering the openings, which slide cover comprises blocking members which can cooperate with the reel hubs to inhibit their rotation. For this purpose the wall with openings has diametrically opposed recesses or cut-outs to allow the blocking members to engage with inner teeth provided in the reel hubs.
