Patent ID: 8345168

Claim:
A display system comprising: a digital broadcast receiver unit for receiving a digital multiplexed signal stream having digital multiplexed signals encoded using an encoding/decoding standard, wherein video signals corresponding to a plurality of different video signal formats are multiplexed in a packet unit in the digital multiplexed signal stream, the unit including: an isolator to isolate one video signal from the digital multiplexed signal; 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-programs, with respective video processing sub-programs providing video processing according to a different video signal format of the plurality of different video signal formats; and a controller to determine a video signal format of the video signal decoded by the decoder by using information obtained from the digital multiplexed signal stream, and to select one video processing of the video processing sub-programs to perform video processing of the video signal decoded by the decoder according to the determined video signal format pertaining to a designated number of scanning lines; and a display apparatus connectable with the digital broadcast receiver unit, including: an input unit which inputs both: a processed video signal processed by the decoder according to the determined video signal format pertaining to the designated number of scanning lines, and the determined video signal format of the processed video signal, which are outputted from the digital broadcast receiver unit, a display to display signals having any of a plurality of differing designated numbers of scanning lines, and which displays said processed video signal inputted by said input unit, wherein a scanning method of the video signal for said display is switched to match a scanning method indicated by the determined video signal format inputted by said input unit.
