摘要： A video processing technique which enables users to effectively watch highlight scenes while listening to audio part thereof in a short period of time is disclosed. Upon input of video data, highlight scene data describing therein a highlight scene(s) in the video data is input or generated. Then, based this highlight scene data, determine a default playback parameter. Control is provided to reproduce the highlight scene(s) of the video data in a way such that when inputting a parameter for determination of a playback scene(s), this input playback parameter is used while giving thereto higher priority than the default playback parameter.

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 digest reproducing apparatus which creates and shows a digest which gives an overview of a whole motion video content regardless of the number of scenes included in an original content. To achieve the above technique, for example, we need to record data on plural still images obtained by encoding plural consecutive still images in time order, detect a scene change in a motion video obtained by reproducing the still image data in time order, calculate an index value indicating the significance level of each still image in the motion video from the still image data, rank scenes in the motion video based on index values indicating the significance levels of still images, and reproduces digest still images included in a specified number of scenes selected according to the ranking.

摘要： An apparatus and a control method for an apparatus includes: a tuner for transmitting a demodulation signal which is a signal generated by demodulating a receiving signal of a digital broadcast; a digital signal processor for decoding the demodulation signal and transmitting a first video signal to an external device; a general-purpose processor for generating a second video signal to be synthesized with the first video signal; a video signal synthesizing circuit for synthesizing the second video signal with the first video signal; and a user interface for accepting from the external device an input of a starting signal which is a signal instructing a start of video signal output. The digital signal processor and the general-purpose processor start respective boot sequences in response to the acceptance of input of the starting signal by the user interface, and the digital signal processor starts the decoding of the demodulation signal before the boot sequence of the general-purpose processor is completed.

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.
