A decoder apparatus which includes a de-multiplexer, which is configured to divide motion picture data from a transport stream, a video decoder, which is configured to decode the divided motion picture data, and a first re-formatter on-screen unit, which is configured to display motion picture data and at least one of first and second graphic data on a screen. The first re-formatter on-screen unit converts motion picture data of a first aspect ratio, which is decoded by the video decoder, and first graphics data, which is produced by applying information relating to a caption corresponding to the motion picture data, into a second aspect ratio, when outputting the motion picture data of the first aspect ratio after conversion into the second aspect ratio, without converting the aspect ratio of second graphic data, which is produced by applying information relating to a program guide.

Decoder device and receiver using the same

A receiver includes a motion picture data decoder which decodes motion picture data to obtain decoded motion picture data, a memory which stores the decoded motion picture data, a video processing unit which mixes the decoded motion picture data with first graphics data and converts the motion picture data to obtain first on-screen data mixed and first format-converted motion picture data, and a second on-screen data multiplexer which mixes the decoded motion picture data with second graphics data to obtain second on-screen data-mixed motion picture data. A first output device outputs the first on-screen data mixed and first format-converted motion picture data, a second output device outputs the second on-screen data mixed motion picture data.

Receiver having motion picture data decoder

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 converters, a plurality of OSD circuits, and means for storing motion picture data used in an analog broadcast in a common memory.
