Disclosed herein are a digital signal processing apparatus, a digital signal processing method, an information center, and a data delivery system capable of judging reliably whether digital signals such as music data recorded on a storage medium have been legally purchased by a customer from a legitimate vendor so that only when the digital signals are judged to be legitimately purchased data will a new service be offered to the customer.

Digital signal processing apparatus, digital signal processing method, information center, and data delivery system

A digital signal processing apparatus, a digital signal processing method, an information center, and a data delivery system are capable of judging reliably whether digital signals such as music data signals recorded on a storage medium have been legally purchased by a customer from a legitimate vendor, so that only when the digital signals are judged to be legitimately purchased data, will a new service be offered to the customer.

A reproducing apparatus and method is provided. The reproducing apparatus includes a detection device, a list preparation device, and a reproduction device. The detection device is configured to detect acquisition of first page information. The list preparation device is configured to prepare a list of content identification information collected at least from the first page information and from second page information linked from the first page information when the detection device detects the acquisition of the first page information, the content identification information being such as to indicate where streaming content data is availably located. The reproduction device is configured to reproduce the streaming content data upon acquisition, the streaming content data corresponding to the content identification information in the list prepared by the list preparation device.

Reproducing apparatus, reproducing method, and reproducing program

A data distribution system that includes a distribution center apparatus for dividing digital content data into segments of multiple frequency bands, and converting the segments of digital content data into encoded data having compressed blocks, each block having a predetermined length unit and constituted by at least bit distribution information, normalized data and quantized data. The encoded data is transmitted so as to superimpose, if an empty portion exists in each of the blocks, a part or all of an identifier for identifying a provider of the digital content data onto the empty portion.

Data distribution system, terminal apparatus, distribution center apparatus, high-efficiency encoding method, high-efficiency encoding apparatus, encoded data decoding method, encoded data decoding apparatus, data transmission method, data transmission apparatus, sub information attaching method, sub information attaching apparatus, and recording medium
