Reception device
The present invention relates to a reception device that can select an optimal component. The reception device includes a first reception unit that receives a video or audio component transmitted on a broadcast wave, a second reception unit that receives a video or audio component distributed via a network, and a control unit that controls the operation of each unit. The control unit selects the optimal video or audio component from a plurality of video and audio components that the reception device can receive.

in the first layer, the first category component is selected in accordance with throughput of the receiving device.
12. The method of claim 7 , wherein
components in different categories are linked to each other with a view tag.
13. A non-transitory computer readable medium including executable instructions, which when executed by a computer cause the computer to execute a method in a receiving device, the method comprising:
receiving, by the receiving device, first, second, third, and fourth components, wherein the first and second components belong to a first category and the third and fourth components belong to a second category;
in a third layer, selecting, by the receiving device, the first component or the second component as a first selected component,
in a second layer, synthesizing, by the receiving device, the first selected component in the third layer and a component not selected in the third layer into a synthesized component,
