Program data and information associated with at least a consumer commodity that appears in a program of the program data are synchronously transmitted. The program data and the information associated therewith are received. The received program data is reproduced. The reproduced data is displayed on a displaying portion. Information associated with a selected one of a plurality of consumer commodities displayed on the displaying portion is extracted and displayed. A viewer can buy the selected consumer commodity at a store corresponding to the extracted information.
摘要:
Program data and information associated with at least one consumer commodity that appears in a program of the program data are synchronously transmitted. The program data and the associated information are received, and the program is reproduced and displayed on a display. One of a plurality of displayed consumer commodities is selected, and at least part of information associated with the selected consumer commodity is extracted and displayed. The extracted information associated with the selected consumer commodity is stored and is accessible after the program is displayed.
摘要:
Data broadcast data, which is broadcast in data broadcasts, is constructed by disposing, for example, EMD (Electric Music Distribution) links required to acquire song data as actual broadcast data, which is broadcast in actual broadcasts by a transmitting device, the actual broadcast data is transmitted, and the data broadcast data wherein the EMD links for the song data in the actual broadcasts are disposed, is transmitted periodically during the transmission of the actual broadcast data. The actual broadcast data and the data broadcast data are received by a user terminal, and the EMD links disposed in the data broadcast data are stored whenever there is an input of an operation to attach a “bookmark”. Thus, audio data such as songs in programs broadcast can easily be acquired by radio.
摘要:
A recording method for embedding in a record medium many types of management information corresponding to many types of record media as additional information added to content data that is recorded on the record medium, performing a first encoding process for the content data to which the additional information has been embedded, performing a second encoding process for the many types of management information; and modulating the content data of which the first encoding process has been performed and the many types of management information of which the second encode process has been performed.
摘要:
A recording method for converting m-bit data into n-bit (where n>m) bit data whose run length is restricted and recoding the converted data on a recording medium, the recording method comprising the steps of when at least preceded data is data containing a special data pattern, lightening the restriction of the run length; and recording data so that the cumulative value of DC components per unit time increase when the data is reproduced in the state that the run length is restricted.
摘要:
A method for recording digital data in accordance with the recording format, in which the type of a loaded recording medium is identified and on the basis of the result of the identification a data format is selected for embedding sub data into data to be recorded onto the loaded recording medium so that the data are readable as optical changes. Whether the recording area in which recording is to be performed is a recording area in which the sub data should be embedded or not is discriminated, and if the result of the discrimination indicates that the area in which recording is to be carried out is a recording area in which the sub data should be recorded, the sub data are embedded and recorded into the data to be recorded in a predetermined recording area on the recording medium on the basis of the selected data format.

摘要:
A recording method for a record medium is disclosed, that comprises the steps of adding right information containing at least copyright management information to at least one of a plurality of pieces of input data, and performing a signal process for the plurality of pieces of the input data in the unit of data to which the right information has been added so as to record the processed data to the record medium.
摘要:
A recording medium having at least a lead-in area, a data recording area to which data is recorded, and a lead-out area, wherein the data recording area comprises a first recording area portion to which data that has been encoded with an error correction code is recorded; and a second recording area portion to which at least data that has been encoded with a plurality of types of generation polynomials as error correction codes.
摘要:
A recording method includes the steps of generating recording data in such a manner that, when m-bit data is converted into a data symbol of n bits (m
