摘要： The present invention provides a data processing method and apparatus capable of shortening the processing time required when editing previously encrypted track data. An example of a transfer of audio track data between a portable player and a storage device is provided. The track data is comprised of one or more parts, each of which in turn is comprised of a series of data blocks. Each block of the track data is encrypted prior to transfer using a block key. The block keys are determined in such a manner that subsequent editing of the track data which results in redistribution of the parts does not require full decryption of the data.

摘要： A lossless encoder and decoder are provided for transmitting a multichannel signal on a medium such as DVD-Audio. The encoder accepts additionally a downmix specification and splits the encoded stream into two substreams, such that a two-channel decoder of meagre computational power can implement the downmix specification by decoding one substream, while a multichannel decoder can decode the original multichannel signal losslessly using both substreams. Further features provide for efficient implementation on 24-bit processors, for confirmation of lossless reproduction to the user, and for benign behaviour in the case of downmix specifications that result in overload. The principle is also extended to mixed-rate signals, where for example some input channels are sampled at 48 kHz and some are sampled at 96 kHz

摘要： On a data recording medium which is divided into sectors and can be accessed on the sector unit basis, when encoded data is divided every predetermined length, a header is added, the data is packetized, a header is further added to the packet to thereby form the pack data, and the resultant data is recorded, if the stuffing is necessary, the stuffing data is inserted to the last of a data area of the packet. Thus, a length of pack header can be fixed. There is no need to provide a padding packet. A situation such that a PES header is encrypted is prevented and no problem occurs when encryption is performed.

摘要： In one aspect of the invention, a stream is divided into two substreams, the first substream providing information relating to a ‘downmix’ signal obtained by matrixing and containing fewer channels than an original multichannel digital signal, and the second substream providing additional information allowing the original multichannel digital signal to be losslessly recovered by a decoder. In a preferred implementation, an encoder furnishes the downmix signal using a cascade of one or more primitive matrix quantizers, each of which implements an n-by-n matrix, followed by selection of the m channels required for the downnix. In a second aspect, a lossless compression system includes a dither seed in the encoded bitstream. The dither seed is used to synchronize a pseudo-random sequence generator in the decoder with a functionally identical generator in an encoder. In a third aspect, encoders and decoders contain uncommitted primitive matrix quantizers, the encoder having logic that accepts a downmix specified as a matrix of coefficients, allocates a number of primitive matrix quantizers to furnish the downmix and optionally allocates a further number to provide matrixing to reduce the data rate.

摘要： A system for selection by a user and delivery to the user over an internetwork transmission channel of selected audio data files at a delivery rate of at least twice the delivery rate for normal, audibly perceptible playback of an audio data file. The user registers the user's selection of audio material with a central library of audio and/or text data files, and a digitized and optionally compressed omnibus file containing the user's selections is prepared and transmitted to the user at a high data transfer rate. The user receives downloads the selected data files to a personal computer or to a portable storage and playback unit (SPU) that may store and play back digitized text or audio data, using a docking station. The user carries this SPU until the user has an opportunity to audio process and play back the text or audio data files in audibly perceptible form.
