Method, device, and non-transitory computer-readable recording medium for supporting relay broadcasting using mobile device
Provided are a method, device, and non-transitory computer-readable recording medium for supporting relay broadcasting using a mobile device. It is possible to reduce a computing load of a repeater device by distributing a computing load required to produce relay broadcasting content to a plurality of photographer devices and thus widen the range of photographer devices that may participate in relay broadcasting.
1. A method of supporting relay broadcasting using a mobile device, which is performed by a repeater device, the method comprising:
receiving first sampling video data and first sampling audio data of first video data and first audio data, respectively, generated by a first photographer device and receiving second sampling video data and second sampling audio data of second video data and second audio data, respectively, generated by a second photographer device;
providing at least one of the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data to the repeater device; and
generating editing data for editing relay broadcasting content including at least one of the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data with reference to an input of a repeater for editing at least one of the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data, wherein:
quality of at least one of the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data, which is transmitted from the first photographer device or the second photographer device and then received by the repeater device, is adaptively determined based on the editing input;
a control signal for adaptively determining the quality is transmitted from the repeater device to the first photographer device or the second photographer device;
quality of data to be edited is determined to be higher than quality of data not to be edited; and
quality of specific data to be edited is determined to be higher than quality of the specific data before or after it is determined that the data is to be edited.
2. The method of claim 1 , wherein the first photographer device and the second photographer device are physically included in one device.
3. A non-transitory computer-readable recording medium storing a computer program for executing the method of claim 2 .
4. The method of claim 1 , wherein:
the first sampling audio data includes a plurality of first audio frames divided from the first audio data, and the first sampling video data includes a plurality of first video frames sampled from the first video data and synchronized with the plurality of first audio frames; and
the second sampling audio data includes a plurality of second audio frames divided from the second audio data, and the second sampling video data includes a plurality of second video frames sampled from the second video data and synchronized with the plurality of second audio frames.
5. A non-transitory computer-readable recording medium storing a computer program for executing the method of claim 4 .
6. The method of claim 1 , wherein the quality includes at least one of a sampling rate, a resolution, and a data size.
7. A non-transitory computer-readable recording medium storing a computer program for executing the method of claim 6 .
8. The method of claim 1 , wherein the editing data includes at least one of information regarding conversion between the first sampling video data and the second sampling video data, information regarding combination between at least one of the first sampling video data and the second sampling video data and at least one of the first sampling audio data and the second sampling audio data, information regarding subtitles combined with the first sampling video data or the second sampling video data, information regarding a graphic element combined with a specific area of the first sampling video data or the second sampling video data, and information regarding a sound effect or relayed voice combined with the first sampling audio data or the second sampling audio data.
9. The method of claim 8 , wherein the editing data is specified by a touch-based editing input that is entered through the repeater device in real time.
10. A non-transitory computer-readable recording medium storing a computer program for executing the method of claim 9 .
11. A non-transitory computer-readable recording medium storing a computer program for executing the method of claim 8 .
12. The method of claim 1 , further comprising transmitting the editing data and data included in the relay broadcasting content among the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data to a viewer device or a storage.
13. A non-transitory computer-readable recording medium storing a computer program for executing the method of claim 12 .
14. A non-transitory computer-readable recording medium storing a computer program for executing the method of claim 1 .
15. A device for supporting relay broadcasting using a mobile device, the device comprising:
a data receiver configured to receive first sampling video data and first sampling audio data of first video data and first audio data, respectively, generated by a first photographer device and receive second sampling video data and second sampling audio data of second video data and second audio data, respectively, generated by a second photographer device; and
a relay broadcasting content editor configured to provide at least one of the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data to a repeater device and generate data for editing relay broadcasting content including at least one of the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data with reference to an input of a repeater for editing at least one of the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data, wherein:
quality of at least one of the first sampling video data, the first sampling audio data, the second sampling video data, and the second sampling audio data, which is transmitted from the first photographer device or the second photographer device and then received by the repeater device, is adaptively determined based on the editing input;
a control signal for adaptively determining the quality is transmitted from the repeater device to the first photographer device or the second photographer device;
quality of data to be edited is determined to be higher than quality of data not to be edited; and
quality of specific data to be edited is determined to be higher than quality of the specific data before or after it is determined the data is to be edited.
