Patent ID: 7889281

Claim:
A display system comprising: digital broadcast receiver unit for receiving a digital multiplexed signal stream having digital multiplexed signals encoded using an encoding/decoding standard, the digital multiplexed signals including video signals corresponding to a plurality of different video signal formats, 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 using information obtained from the digital multiplexed signal to determine a video signal format of the video signal decoded by the decoder, and selecting 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 coupleable 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 a 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 which is able 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.
