1. A digital broadcast receiving apparatus comprising:
a receiver capable of receiving digital multiplexed signals including video signals of at least three different video programs encoded using an encoding/decoding standard in one transport stream, video signal formats of the video signals including a plurality of different video signal formats having different combination of the number of scan lines and a scan method; an isolator to isolate a video signal of one video program to be viewed from the digital multiplexed signals; a decoder to decode the video signal from the isolator according to the encoding/decoding standard; a processor to execute a plurality of video processing sub software programs, with respective video processing sub software programs providing video processing according to a different combination of the number of scan lines and a scan method of the plurality of different video signal formats; a controller using information obtained from the digital multiplexed signal to determine a combination of the number of scan lines and a scan method of the video signal decoded by the decoder, and selecting one video processing of the video processing sub software programs to perform video processing for the video signal decoded by the decoder according to the determined combination of the number of scan lines and the scan method; and a display to display a video signal processed by the processor.
