摘要: A decoding apparatus for selectively decoding compressed video or audio signal included in a data signal. The decoding apparatus includes a demultiplexer that receives and separates a data signal from a compressed input signal. A video decoder and an audio decoder are provided to decode compressed video or audio signals stored in a decoder buffer. The decoding apparatus uses a memory to store the data signal separated by the demultiplexer, and a CPU to analyze the data signal stored in the memory. The CPU causes the data signal analyzed by the CPU to be stored in the decoder buffer if the analyzed data signal includes a compressed video signal or a compressed audio signal, and the compression method used for the compressed video signal or the compressed audio signal included in the data signal can be decoded by the video decoder or the audio decoder.

摘要: In order to avoid content deteriorations caused by embedment of a digital watermark into a moving picture, a process to search a picture for a motion and a process to filter a picture for medical care must be carried out, raising a processing cost. It is thus difficult to implement equipment for processing such pictures at a low cost. In a compound apparatus for encoding compressed code of a moving picture by employing a unit for embedding a digital watermark into a picture, a digital-watermark embedment quantity is determined by using a motion vector and a quantization parameter in a process to embed a digital watermark into the picture. It is thus no longer necessary to carry out the process to search a picture for a motion and the process to filter a picture for medical care for embedment of a digital watermark so that the cost of the entire apparatus can be reduced substantially.

摘要: A pointing device (28), comprising light sources (30) and monitored by a computer vision task running in a microcontroller (108) and a computer (24). The computer vision task computes the spatial position and orientation of the pointing device, and enables an operator to control virtual three dimensional objects (73) on the display (22) of the computer. Images (78) are captured by a video camera (20) and digitized, and only image rows that contain bright pixels (80) from the light sources are processed. The light sources are the tips of optic fibers (30) guiding light from a laser diode (32), and an optical filter (46) on the camera is matched to the wavelength of the laser diode.

摘要: A contents reproduction device realizes reduction of power consumption by controlling power supply control according to the input contents. More specifically, in the contents reproduction device, the PSI analysis unit analyzes additional information in the inputted contents so as to check whether video contents are contained or the signal detection unit checks whether the inputted contents contain a video signal. According to the check result, the video information detection unit detects whether the inputted contents contain video information and outputs the detection result to the power control unit. When the inputted contents contain video information, the power control unit supplies power to the display. When no video information is contained, the power control unit stops power supply to the display and turns off power supply to the display.

The terminal is provided with input (101, 102, 106 and 107) through which such information as images and sounds is inputted, channel control sections (123 and 124) which output the input information to channels and receive information from the channels, output (103, 104, 108, 109 and 105) which output the information received from the channels in the form of images, sounds, etc., a codec (110) which is provided between the input and output and the control sections, encodes the input information in one of multiple encoding modes in which electric power is differently consumed, and decodes the information inputted from the channels, and a control section (133) which controls the selection of the encoding mode. This terminal can continue information communication for a required period of time at minimum power consumption at the sacrifice of the quality of transmitted information. Therefore, either the power consumption or quality of information can be adequately selected according to the transmission.
