Abstract: One embodiment of the present invention provides a signal-recording system. During operation, the system receives a wideband multi-channel radio frequency (RF) signal, which includes a plurality of single-channel RF signals modulated at different carrier frequencies.

Abstract: Upon receiving a first instruction by an instruction receiving unit, a power supply control unit causes a first power supply unit to supply power to a first acquisition unit, and controls a second power supply unit so that power is not supplied to a second acquisition unit. A reproduction unit reproduces a first content acquired by the first acquisition unit. When a predetermined condition is met during a reproduction period in which the reproduction unit is reproducing the first content, the power supply control unit causes a second power supply unit to supply power to the second acquisition unit during the reproduction period. When the instruction receiving unit receives a second instruction, the reproduction unit reproduces a second content acquired by the second acquisition unit, and the power supply control unit causes the first power supply unit to stop the supplying of power to the first acquisition unit.

Abstract: A signal from each of an array of microphones is analyzed. For at least one subset of microphone signals, a time difference is estimated, which characterizes the relative time delays between the signals in the subset. A direction is estimated from which microphone inputs arrive from one or more acoustic sources, based at least partially on the estimated time differences. The microphone signals are filtered in relation to at least one filter transfer function, related to one or more filters. A first filter transfer function component has a value related to a first spatial orientation of the arrival direction, and a second component has a value related to a spatial orientation that is substantially orthogonal in relation to the first. A third filter function may have a fixed value. A driving signal for at least two loudspeakers is computed based on the filtering.

Abstract: The present invention prevents data stored in memory cards from being damaged while maintaining the operability of inserting and ejecting memory cards. A device has a connection section to which a memory card 11 is connected. The memory card 11 is different from an optical disc 10 on which image data are recorded. The device checks whether the memory card 11 is connected to the connection section. When the device starts performing certain processes to the memory card 11 after detecting that the memory card 11 is connected, the device performs mount processes. When the device stops performing the certain processes, the device immediately performs unmount processes to the memory card 11. The memory card 11 is unmounted while the device is not performing the certain processes. Unmounting the memory card 11 prevents data stored in the memory card 11 from being damaged even if a user accidentally ejects it.

Abstract: A method for recovering video data in a disk when a reading error occurs is provided. First, the disk is scanned to obtain a next writable address (NWA) of a last video chapter previously recorded into the disk. An end address of a successfully recorded video chapter is then read from a specific area of the disk and stored into a memory. Next, when a disk player/recorder is requested to read content of data according to the NWA, the disk player/recorder determines whether the content of the data is a file system. If the content of the data is not a file system, the NWA obtained by scanning the disk is replaced with the end address read from the specific area to read the file system, so as to recover the video data in the disk. Thereby, the video data in the disk can be protected.

Abstract: According to the present invention, there is provided an image reproducing apparatus for reproducing a digital broadcast based on the MPEG standard. When performing special reproduction by use of access-unit management information that is used to manage access units, the image reproducing apparatus reads ahead the access-unit management information and compares time stamps. As a result of the comparison, if it is judged that the absence of a piece of the access-unit management information exists, the special reproduction is then performed by use of simple information that is used to manage a stream. This makes it possible to continuously perform the special reproduction even if it becomes impossible to utilize the access-unit management information.

Abstract: When the recording format of an image recorded on a magnetic tape (709) is changed, a playback time period of an image signal by a REC review function is extended. Even when the recording format is changed during playback of an image signal by the REC review function, an image (409) recorded in the recording format after change can be displayed after a blue-backed screen (408) is displayed. Therefore, the user can determine whether the blue-backed screen (408) is displayed due to switching of the system or due to an unrecorded part of an image signal. Hence, the user can be prevented from overwriting a new image signal on the recorded region of an image signal by mistake.
