Abstract: 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. Restrictions are made on the shortest cut duration lenient in editing the stream. A controller detects each edit point set on the stream and identifies the 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 the timing to start decoding the fewest possible pictures. Subsequently, the controller controls 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.

Abstract: 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 ratio, the device can maintain the quality of the on-screen image D3.

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.

Abstract: In the invention, high quality image data can be encoded using encoders, which are originally designed for encoding image data of ordinary image quality. This can be done by intra-encoding Video In signal supplied from input circuit by two encoders when SDI In signal is an HD signal. An entire picture area is divided into a first group and a second group of divisional picture domains, which are distributed over the picture area. The centers of gravity of the respective groups substantially coincide. An encoder encodes image data extracted corresponding to the first group from active video data of Video In signal, while the other encoder encodes image data extracted corresponding to the second group from the active video data of Video In signal. The resultant MPEG signals output from the respective encoders are combined to form a stream.
