    摘要： Of three-color signals R′, G′ and B′, obtained as output signals of multipliers 156R, 156G and 156B, designed to effectuate luminance compression of the three-color signals R, G and B sent to input terminals 151R, 151G and 151B by multiplying the signals R, G and B with a coefficient k, in such a manner as to maintain saturation and color hue of the three-color signals R, G and B, only the saturation of color video signals represented by the three-color signals R′, G′ and B′ is compressed by first saturation compression circuits 160R, 160G and 160B so that the signal level of the signal of the three-color signals R′, G′ and B′ having the highest signal level will be the clip level. Of the three prime color signals R″, G″ and B″ obtained as output signals of the first saturation compression circuits 160R, 160G and 160B, only the saturation of the signals R″, G″ and B″ is compressed, in a state in which the luminance and the color hue of the signals R″, G″ and B″ are maintained, in order to obtain three prime color signals R*, G* and B* the high luminance portion of which has only saturation changed.

    摘要： A shortest cut duration is a minimum required period between an edit point set on a stream of pictures such as an MPEG stream and the next edit point set on the stream. It is an object of the present invention to make restrictions on the shortest cut duration lenient in a process to seamlessly reproduce a result of editing the stream in order to enhance the freedom of editing in carrying out a process of editing the stream. In order to achieve this object, a controller detects each edit point set on the stream and, for the edit point, the controller identifies fewest possible pictures, which are not to be displayed but must be decoded first before decoding a picture to be displayed after the edit point. Then, the controller finds a start point representing a timing to start a process of decoding the one or fewest possible pictures. Subsequently, the controller controls processes carried out by decoders to decode the stream in picture units on the basis of the start point, and controls a switcher to select one of outputs of the decoders on the basis of the edit point.

    摘要： The present invention allows a device to easily convert an on-screen image in HD format or SD format without increasing the processing load. The device according to an embodiment of the present invention uses the on-screen image D3 in which the number of horizontal pixels is set between horizontal pixel counts of HD format and horizontal pixel counts of SD format. Therefore, the device can utilize a relatively simple conversion ratio when converting the image in HD and SD format. This tremendously reduces the computational processing load. In addition, since the device uses the simple conversion ration, the device can maintain the quality of the on-screen image D3.
