Abstract
An object of the present application is to provide the display of motion picture data used in both of analog and digital broadcasts with high picture quality and a common user interface. The above object can be achieved by providing a plurality of picture format converting means, a plurality of OSD means and means for taking motion picture data used in an analog broadcast in a common memory.
Claims3
A decoder device, comprising:
- a motion picture data decoder which decodes digital motion picture data to thereby obtain decoded motion picture data;
- a memory which stores the decoded motion picture data therein;
- a first on-screen data multiplexer which mixes the decoded motion picture data with first graphics data to thereby obtain first on-screen data-mixed motion picture data;
- a picture format converter which converts the first on-screen data-mixed motion picture data into a picture format to thereby obtain format-converted motion picture data;
- a second on-screen data multiplexer which mixes the format-converted motion picture data with second graphics data to thereby obtain second on-screen data-mixed motion picture data;
- and
- an output device which outputs the second on-screen data-mixed motion picture data therefrom.
