Abstract: A server system in the form of an automatic vending machine is disposed in a store. A distributor has a main server. A reproducing and connecting device is disposed in a home. The server system and the main server are connected through a bi-directional dedicated line and whole music information (music data and additional information) is transmitted therebetween. The main server 2 and the reproducing and connecting device are connected through the Internet. Additional information of music information is transferred from the main server to the reproducing and connecting device. The user searches for a song that he or she will buy corresponding to the additional information and decides to buy the selected song. In the store, the user can record a song that he or she has decided to buy corresponding to buying information to a record medium.

Abstract: Digital audio data which have a predetermined packet structure are divided into units including a predetermined number of bits; each unit of the divided digital audio data is converted into specific data to be encoded; the encoded data are arranged in blanking intervals of video data; the digital audio data are transmitted as well as the video data using a transmission line for the video data, and the video data and the audio data may be simultaneously and favorably transmitted, adopting an existing video-data transmission format such as the DVI standard.

Abstract: This invention provides a data transmission method and a data receiving method which enable audio data to be multiplexed into video data and be transmitted using a DVI standard cable or the like satisfactorily with a simple configuration. From a data transmitting end, a superimposed video/audio data signal in which audio data are superimposed over a video blanking interval of video data in superimposition timing that is generated using a video blank sync signal and a pixel clock, are transmitted to a data receiving end through the DVI cable, together with the video blank sync signal and the pixel clock.

Abstract: The present invention is relative to a video signal transmitting/receiving system in which digital video signals are transmitted from a transmitter (30) to a receiver (50) using a line (9) as a transmission channel. The transmitter (30) converts the video signals to be transmitted to a bit string longer in data length than a pixel making up the video signals, allocates a plural number of the bit strings to a blanking period during which pixel data in the pixel string is not transmitted and, using these bit strings, transmits the same superposed data a plural number of times. The receiver (50) extracts the specified bit strings indicating the blanking period from the received data and performs majority processing on the results of demodulation of the extracted bit strings to decide on output data. This reduces errors in reception of supplementary data to simplify the circuit structure as well as to ameliorate the error rate.

Abstract: An error-correction coding method and an error-correction decoding method utilize error detection and error correction for an audio signal when a video signal and the audio signal are multiplexed and transmitted by a DVI. After an error correction code is added to each sample (sample data unit) of the digital audio signal, n continuous (n: integer equal to or larger than 2) pieces of the samples (sample data units) of the digital audio signal, to which error correction codes are added, are interleaved to generate a coded audio signal.
