Video display apparatus, video display method, and video signal processing apparatus
A video display apparatus includes: an inputter that receives an input of divided video signals representing divided images obtained by dividing an output image and acquires signal information for each of the divided video signals; a video signal processor that applies processing to the divided video signals and generates an output video signal representing an image obtained by combining the divided images; a controller that acquires the signal information from the inputter and supplies a control signal relating to the processing to the video signal processor; and a display that displays the image represented by the output video signal, and the number of kinds of signal information acquired by the controller with respect to some divided video signals among the divided video signals is greater than the number of kinds of signal information acquired by the controller with respect to the other divided video signals.
1. A video display apparatus comprising:
an inputter that receives an input of a plurality of divided video signals representing a plurality of divided images obtained by dividing an output image and acquires signal information for each of the divided video signals;
a video signal processor that applies processing to the plurality of divided video signals and generates an output video signal representing an image obtained by combining the divided images;
a controller that acquires the signal information from the inputter and supplies a control signal relating to the processing to the video signal processor; and
a display that displays the image represented by the output video signal,
wherein the number of kinds of signal information acquired by the controller with respect to some divided video signals among the plurality of divided video signals is greater than the number of kinds of signal information acquired by the controller with respect to the other divided video signals.
2. The video display apparatus according to claim 1 , wherein the number of kinds of signal information acquired by the controller with respect to the other divided video signals is one.
3. The video display apparatus according to claim 1 , wherein the signal information acquired by the controller with respect to the other divided video signals is only signal information representing presence or absence of each of the divided video signals.
4. The video display apparatus according to claim 1 , wherein the controller causes the video signal processor to generate the output video signal so that a predetermined image is displayed in an area on the display that corresponds to a divided video signal of which absence is indicated by the signal information.
5. The video display apparatus according to claim 4 , wherein the predetermined image comprises a muted image of the video display apparatus.
6. The video display apparatus according to claim 1 , wherein some of the divided video signals comprise divided video signals selected on the basis of signal information representing presence or absence of predetermined information included in payload information of the divided video signals among the signal information acquired by the inputter.
7. The video display apparatus according to claim 1 , wherein the controller selects some of the divided video signals in accordance with a selection instruction by a user.
8. The video display apparatus according to claim 1 , wherein the controller acquires the signal information that has been acquired from the divided video signals on a predetermined cycle by the inputter, on a cycle that is longer than the predetermined cycle.
9. The video display apparatus according to claim 1 , wherein the controller supplies the control signal to control the video signal processor so that the output video signal that includes an image for an on-screen display in accordance with an input operation by a user is generated.
10. A video display method comprising:
inputting a plurality of divided video signals representing a plurality of divided images obtained by dividing an output image to an inputter;
acquiring, by the inputter, signal information for each of the divided video signals;
acquiring, by a controller, the signal information from the inputter for each of the divided video signals;
applying processing to the plurality of divided video signals;
generating an output video signal representing an image obtained by combining the divided images; and
displaying an image represented by the output video signal,
wherein the number of kinds of signal information acquired by the controller with respect to some divided video signals among the plurality of divided video signals is greater than the number of kinds of signal information acquired by the controller with respect to the other divided video signals.
11. A video signal processing apparatus comprising:
an inputter that receives an input of a plurality of divided video signals representing a plurality of divided images obtained by dividing an output image and acquires signal information for each of the divided video signals;
a video signal processor that applies processing to the plurality of divided video signals and generates an output video signal representing an image obtained by combining the divided images; and
a controller that acquires the signal information from the inputter and supplies a control signal relating to the processing to the video signal processor,
wherein the number of kinds of signal information acquired by the controller with respect to some divided video signals among the plurality of divided video signals is greater than the number of kinds of signal information acquired by the controller with respect to the other divided video signals.
