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 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: A spatial motion pattern input system for causing a control target device to perform control according to a spatial motion pattern of a spatial control input device, comprises a move sensing section for sensing at least the amount of movements of the spatial control input device on two axes among the amount of movements of the device on three specific nonparallel axes in space, a conversion section for converting the amount of spatial movements composed of at least two amounts sensed at the move sensing section into a motion vector sequence, an identification section for performing identification by comparing a motion vector sequence corresponding to a basic motion pattern previously entered with the motion vector sequence, and an execution section for controlling the control target device on the basis of the recognition result from the identification section.
