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.

a receiver configured to receive a first component, a second component, and at least another component belonging to one of at least two categories including audio and video;
a control circuitry configured to control operation of the receiver,
wherein in a third layer, the control circuitry is configured to select the first component or the second component as a first selected component,
in a second layer, the control circuitry is configured to synthesize the first selected component in the third layer and a component not selected in the third layer into a synthesized component,
in a first layer, the control circuitry is configured to select the first selected component selected in the third layer or the synthesized component as a selected component for the one of the at least two categories, and the control circuitry is configured to output the selected component for the one of the at least two categories to a rendering device.
2. The reception device of claim 1 , wherein the first component is a broadcast component and the second component is a communication component.
3. The reception device of claim 2 , wherein
in the third layer, the control circuitry selects the first selected component at an optimal bit rate from the first component and the second component at different bit rates depending on variations in Carrier or Noise (C/N) of a broadcast signal including the first component or congestion of a communication channel carrying the second component.
4. The reception device of claim 3 , wherein
the first selected component in the third layer is a base layer and the component not selected in the third layer is an extended layer.
5. The reception device of claim 3 , wherein
in the first layer, the control circuitry selects the component in accordance with throughput of the reception device.
6. The reception device of claim 2 , wherein
components in different categories are linked to each other with a view tag.
7. A method comprising:
receiving, by a receiving device, a first component, a second component, and at least another component belonging to one of at least two categories including audio and video;
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,
in a first layer, selecting, by the receiving device, the first selected component selected in the third layer or the synthesized component as a selected component for the one of the at least two categories, and
outputting the selected component for the one of the at least two categories to a rendering device.
8. The method of claim 7 , wherein the first component is a broadcast component and the second component is a communication component.
9. The method of claim 8 , wherein
in the third layer, the first selected component is selected at an optimal bit rate from the first component and the second component at different bit rates depending on variations in Carrier or Noise (C/N) of a broadcast signal including the first component or congestion of a communication channel carrying the second component.
10. The method of claim 8 , wherein
the first selected component in the third layer is a base layer and the component not selected in the third layer is an extended layer.
11. The method of claim 8 , wherein
in the first layer, the selected component for the one of the at least two categories 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, a first component, a second component, and at least another component belonging to one of at least two categories including audio and video;
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,
in a first layer, selecting, by the receiving device, the first selected component selected in the third layer or the synthesized component as a selected component for the one of the at least two categories, and
outputting the selected component for the one of the at least two categories to a rendering device.
14. The non-transitory computer readable medium of claim 13 , wherein the first component is a broadcast component and the second component is a communication component.
15. The non-transitory computer readable medium of claim 14 , wherein
in the third layer, the first selected component is selected at an optimal bit rate from the first component and the second component at different bit rates depending on variations in Carrier or Noise (C/N) of a broadcast signal including the first component or congestion of a communication channel carrying the second component.
16. The non-transitory computer readable medium of claim 14 , wherein
the first selected component in the third layer is a base layer and the component not selected in the third layer is an extended layer.
17. The non-transitory computer readable medium of claim 14 , wherein
in the first layer, the selected component for the one of the at least two categories is selected in accordance with throughput of the receiving device.
18. The non-transitory computer readable medium of claim 13 , wherein
components in different categories are linked to each other with a view tag.
