摘要： A content usage system includes a recording and playback device and a portable electronic device mutually connected via a network. When the recording and playback device receives a certain command while outputting digital content, that content is converted into transfer content suitable for use with the portable electronic device, and then stored with metadata indicating that the content is transfer content. Using the metadata, the recording and playback device is able to generate and transmit a list of transfer content upon request from the portable electronic device. Using the list, the user of the portable electronic device then selects desired transfer content from the list and sends a transfer content request. In response, the recording and playback device transmits the selected transfer content to the portable electronic device, thereby making the content available for use on the portable electronic device.

摘要： A DSV control bit determining/inserting unit 11 inserts DSV control bits for execution of DSV control into an input data string and outputs the data string including the DSV control bits to a modulation unit 12. The modulation unit 12 converts the data string with a basic data length of 2 bits into variable length code with a basic code length of 3 bits in accordance with a conversion table and outputs the code resulting from the conversion to a NRZI encoding unit 13. The conversion table used by the modulation unit 12 includes substitution codes for limiting the number of consecutive appearances of a minimum run to a predetermined value and substitution codes for keeping a run length limit. In addition, the conversion table enforces a conversion rule, according to which the remainder of division of the “1” count of an element in a data string by 2 having a value of 0 or 1 shall always be equal to the remainder of division of the “1” count of an element in the code resulting from conversion of the data string by 2.

摘要： The invention relates to an information processing apparatus and method by which it is made possible to efficiently provide change information of broadcast contents in accordance with the necessity of a user. A server 2 compares contents information acquired from a contents information production apparatus 5 and contents information prior by one generation stored in a contents information database 11. If a result of the comparison proves that the contents information has a change, the contents information is registered with a change code added thereto into a change information database 12. When contents information of broadcast contents corresponding to reservation contents information transmitted from a broadcast receiving and recording apparatus 3-1 is found in the change information database 12, the server 2 transmits change information to the broadcast receiving and recording apparatus 3-1. The invention can be applied to a system which provides contents information through the Internet.

摘要： The present invention provides an optical disc recording method and an optical disc recording apparatus for an optical disc of a high-density recording whose master can be subjected cutting with a high yield. The present invention also provides an optical disc access method and an optical disc apparatus capable of a high-density recording as well as an easy access. An address signal generating circuit 5 generates an address signal indicating an address data as a code having a minimum run length longer than a minimum run length of a modulated code based on a predetermined modulation rule of a user data recorded/reproduced via a recording/reproduction area. The address signal is recorded by an optical head 4 in a reproduction-dedicated area of a master disc 1.

摘要： Clock is reproduced stably. If data (limiting code) containing a plurality of consecutive minimum inversion interval Tmin is contained in the data inputted from a shift register, a Tmin consecution limiting code detection unit detects such consecutive interval. A constraint length judgement unit judges the constraint length i to be the constraint length corresponding to the code for limiting the constraint length i when a detection signal is inputted from the Tmin consecution limiting code detection unit, and outputs the judged constant length to a multiplexer. The multiplexer selects the output of a converter corresponding to the constraint length supplied from the constraint length judgement unit out of converters 14-1 to 14-r, and supplies the selected output to a run detection processing unit through a buffer.
摘要翻译：时钟被稳定地再现。如果包含多个连续最小反转间隔Tmin的数据（限制码）包含在从移位寄存器输入的数据中，则Tmin连续限制码检测单元检测这样的连续间隔。约束长度判断单元将约束长度i判定为与从Tmin连接限制码检测单元输入检测信号时用于限制约束长度i的代码相对应的约束长度，并将判断出的常数长度输出到多路复用器。复用器从转换器14-1至14-r中选择对应于从约束长度判断单元提供的约束长度的转换器的输出，并通过缓冲器将所选择的输出提供给运行检测处理单元。
