Abstract: A high definition television player records and plays back HDTV signals in a closed circuit to demonstrate high definition television. The signals are recorded on a hard drive, CD, DVD or the like in discrete 2-meg data blocks, with each block of data being separately identified. The invention provides for continuous looping play of a desired program or programs by identifying the starting data block and ending data block of the program. The program play is begun at the starting block. When the program is finished at the end block, play continues at the start block, and so on until the stop button is pushed.

Abstract: The system is for passing clear DVD program streams from a CPU (central processing unit) to an MPEG-2 decoder. In the system the CPU is connected to a first bus interface. A system memory is connected to the first bus interface via a memory bus. A second bus interface is connected to the first bus interface via a PCI (peripheral component interconnect) bus and a DVD data source is connected to the second bus interface. A packet data decoder is connected to the memory bus via a buffer. The CPU reads DVD data from the DVD data source across the PCI bus, decrypts the DVD data and creates a packet data, and sends the packet data to the buffer via the memory bus. The MPEG-2 decoder receives the packet data, via the transport bus, from the buffer. In more general terms, the system connects two existing busses in a computer of set-top box.

Abstract: Predetermined information, for example, BCA data and a total reproduction time etc. is read from a loaded disc and the disc information thus read is supplied to a CPU 1. Then, a discrete setting area 3b is retrieved to determine whether or not parameters are registered in correspondence with the disc information thus read. When it is determined that the parameters are registered, the parameters registered in correspondence with the disc information is read from the discrete setting area 3b and set in an audio decoder 12 and a subpicture decoder 13, respectively. When it is determined that the parameters are not registered, standard parameters are read from a standard setting area 3a and set to the audio decoder 12 and the subpicture decoder 13, respectively.

Abstract: A method for playing back a program which includes one or more interactive applications. A program which is stored, either in the form of a data stream or as a set of files is played back from a storage device. When playback is started, applications which are detected are launched. Applications are detected in the playback of pushed content when they become available in the playback stream. Applications are detected in the playback of pulled content by comparing the validity ranges of the applications to a current playback index. When special playback modes are used, signals which affect the lifecycle of an application are detected and corresponding signals are generated to maintain the proper state of the application. During these special playback modes, these various notification signals may be conveyed to applications which are configured to operate during these modes.

Abstract: A transmitter comprises a demodulation means for demodulating inputted stream data to digital data, and outputting the digital data to a digital interface; a decoding means for decoding the digital data to obtain an analog signal; and a format conversion means for converting the format of the analog signal, and outputting the analog signal to an analog interface. A recorder comprises a judgement means for judging whether the inputted digital data is recordable by the recorder or reproducible after recording; a data recording means for recording the digital data on a recording medium when the judgement means judges that the digital data is recordable; and a coding means for coding the analog signal when the judgement means judges that the digital data is unrecordable. Therefore, the data outputted from the transmitter such as a set-top box can be reliably recorded by the recorder.
