Abstract: A method is for controlling operation mode. The method includes: activating an application for controlling a media reproduction system that reproduces at least one of audio and video files; disabling an operation mode switching function for switching a processing speed of a processor in accordance with a load of the processor while the application is activated; managing a state of the application by the application; determining an operation mode suitable for the state by the application; and controlling the media reproduction system to be performed in the operation mode by the processor.

Abstract: A control system realizes a playback function by playing back stream data read out from a medium by using a decoder. When special playback functions corresponding to pause, fast forward, and rewind are to be performed, the control system moves a read start pointer to the head of a data block constructing a data format, and sets as a restart position of a playback operation.

Abstract: A portable recording and reproducing apparatus has a power supply unit configured to receive a direct current from an external power supply device C and charge a built-in battery with the direct current to supply electricity to respective units, an input unit configured to receive an instruction signal for instructing acquisition of content information from the external power supply device, a recording unit configured to record the content information in a recording area, a communication unit configured to communicate with an external device so as to acquire content information, and a control unit configured to, when receiving the instruction signal from the input unit, control to request the external device to transfer the content information through the communication unit, acquire the content information, record the content information in the recording unit, and read out and reproduce the content information from the recording unit.

Abstract: A portable recording and reproducing apparatus has a communication unit configured to make communication with an external device, a recording unit configured to record contents information, a display unit configured to display image information, and a controller configured to notify image size information displayable on the display unit via the communication unit to the external device, to make an instruction of transferring desired contents information and image information associated therewith, to record the contents information and the image information in the recording unit when receiving the same, and further to display the associated image information on the display unit while reading and reproducing it.

Abstract: An electronic apparatus includes a touch pad having an operation surface formed by a first surface extending vertically or horizontally, and a second surface which is contiguous to the first surface at right angles, a detection unit which detects the operation position and the operation direction of a touch operation made on the operation surface of the touch pad, and a display panel which displays the detection content detected by the detection unit.

Abstract: According to a data display method, data having a program unit and instruction data for the program unit multiplexed on bit stream data is received. The program unit is extracted from the received data and is stored in a memory. The instruction data is extracted from the received data, and the program unit or part thereof specified by the instruction data is read from the memory and is executed. Then, the bit stream data and the execution result are displayed. This ensures smooth synchronization of reproduction of a bit stream with execution of an associated program and efficient use of resources.

Abstract: A video camera apparatus includes a video encoding section which performs intra- or inter-frame encoding for a video signal input from a solid state image sensor, a recording section which records the video signal compression-encoded by the video encoding section as a video file on a recording medium, and a control section which executes a first motion video shooting and recording mode for obtaining a video file including the compression-encoded video signal to be transmitted in real time to a partner destination via a network, and controls the video encoding section to match the bit rate of the encoded signal obtained by the video encoding section with the communication speed of the network used to transmit the video file when the first motion video shooting and recording mode is selected.

Abstract: To transfer an image signal from a electronic camera head to a personal computer, a PC card provides the interface between the camera head and the personal computer. The PC card is removably attached to the personal computer. As instructed by the personal computer, the PC card operates the camera head, sets its states, writes image data into a memory, reads the image data from the memory for transmission to the personal computer, generates control signals for a light refracting member, and informs the personal computer of the state of the camera head.
