摘要： When performing special reproduction with a video recording and reproducing apparatus that reproduces an AV stream, a controller of the video recording and reproducing apparatus calculates a reproduction position in AU at desired time by referring to a timestamp that is added to the head of AU of two adjacent AV streams, gives an instruction of an I-picture exclusive mode to output only I-pictures to a decoder, and reproduces an I-picture.With such arrangement, in a video recording and reproducing apparatus which records and reproduces digital TV broadcasting, it becomes possible to execute special reproduction such as fast-forwarding reproduction of data in which MPEG2-TS is recorded even if the data does not contain position information of I-picture such as SI.

摘要： A push-pull circuit formed of transistors drives a peaking capacitor of an amplifier circuit to enhance charge and discharge of the peaking capacitor. This reduces a bias current, resulting in reduction of a power consumption. A feedback impedance is connected to an emitter of a transistor to feed an output signal back to an input of the amplifier circuit as a current signal in a wide frequency range. Thus, a high-power, wideband amplifier is accomplished.

摘要： In a digital contents receiver for receiving transmitted digital contents, the digital contents include at least component information indicating an element which constitutes a program of the contents. When the component information indicates that the received digital contents are a 3D component, it is determined whether a display part corresponds to display of the 3D component. If the display part corresponds to display of the 3D component, the received digital contents are displayed in 3D.

摘要： The usability while performing copy control can be enhanced in the case of recording a digital broadcast program for which recording of one generation is permitted (“Copy One Generation”). When an output route in the case of copying digital contents from a first recording apparatus to a second recording apparatus is via LAN, authentication is executed between the first recording apparatus and the second recording apparatus. The capability of a move process with a predetermined copy number of multiple copies being kept is confirmed, and dedicated key information is shared to be used for encryption and decryption of the digital contents moved with the predetermined copy number of multiple copies being kept. Then, the digital contents recorded and managed in the first recording apparatus is added with the information about the predetermined copy number of multiple copies, and transmitted.

摘要： An output control method for controlling copy operation for a digital broadcast program permitted to be recorded for one generation (copy one generation) with an improved operating convenience. A digital content and a plurality of types of copy control information for controlling the copies of the digital content are received, and in accordance with the copy control information, the digital content is output to a plurality of recording media connected through a network. If first information contained in the copy control information received indicates copy generation information to permit copies for one generation and second information contained in the copy control information indicates “limited number of copies permitted” mode permitting a predetermined number of copies, then the digital content is output to only one of the recording media in a state permitting copying up to the predetermined number.

摘要： A satisfactory reproduction is still enabled with recorded MPEG2-TS having a jitter or the like. A recording/reproducing device includes: a reading unit that reads data to which a time stamp is added and for which reference information is multiplexed to permit the acquisition side to reproduce a clock; an output controller outputting data as read-out data at a timing depending on time stamp information; a selection unit changing the operation by the output controller; a time stamp deletion unit removing time stamp information; a separation unit separating the data; a detection unit that determines whether the reference information is unauthorized; and a buffer management unit controlling a starting/halting of reading in accordance with the remaining volume of a buffer for temporarily storing data.

摘要： Formerly, it was difficult to exercise proper control for recording and outputting a plurality of contiguous data. To solve this problem, for example, a plurality of contiguous data are acquired from a stream in which the reference information for reproducing at an acquisition end a clock synchronized with a system clock prevailing at the time of generation is multiplexed. A plurality of timestamped data are then read from recording means. Timestamp information is removed from the read timestamped information. The resulting data without the timestamp information is handled as the read data and output with the timing dependent on the timestamp information. The timestamp information generation operation performed for a write and the output operation performed for a read with the timing dependent on the timestamp information are synchronized with an adjusted clock.
