Abstract

A method for requesting resource allocation includes receiving a target quality of a video transmitted from a server, from the server, determining whether a ratio between a quality of a transmitted video and the target quality is less than a predetermined ratio threshold value, based on a Peak signal to Noise Ratio (PSNR) or frame-rate in a predetermined time section, and requesting allocation of additional resources for the video to the server when the ratio of between the quality of the transmitted video and the target quality is less than the ratio threshold value. Other embodiments including an apparatus for requesting resource allocation are also disclosed.

Claims

1. A method for requesting resource allocation by a terminal, the method comprising:

receiving a target standard for a quality of a video from a server;

determining whether a ratio of correspondence between the quality of a video and the target standard is less than a predetermined ratio threshold value, based on a Peak signal to Noise Ratio (PSNR) or frame-rate in a predetermined time section; and

requesting allocation of an additional resource for the video to the server when the ratio of correspondence between the quality of the video and the target standard is less than the ratio threshold value.

2. The method of claim 1, further comprising:

requesting allocation of an additional resource to the server when a time greater than or equal to a predetermined time threshold value elapses while the quality of the video fails to satisfy the target standard.

3. The method of claim 2, wherein the target standard is set by a spatio-temporal range formed of at least two coordinates on a PSNR and frame-rate plane.

4. The method of claim 1, further comprising:

receiving the ratio threshold value from the server.

5. The method of claim 4, further comprising:

receiving a report condition from the server; and

reporting a result of measuring a quality of a video when the report condition is satisfied, to the server.

6. An apparatus for requesting resource allocation by a terminal, comprising:

a communication unit configured to transmit or receive a signal;

a controller configured to;

receive a target standard for a quality of a video from a server,

determine whether a ratio of correspondence between the quality of a video and the target standard is less than a predetermined ratio threshold value, based on a Peak signal to Noise Ratio (PSNR) or frame-rate in a predetermined time section, and

request allocation of an additional resource for the video to the server when the ratio of correspondence between the quality of the video and the target standard is less than the ratio threshold value.

7. The apparatus of claim 6, wherein the controller is configured to request allocation of an additional resource to the server when a time greater than or equal to at least predetermined time threshold value elapses while the quality of the video fails to satisfy the target standard.

8. The apparatus of claim 7, wherein the target standard is set by a spatio-temporal range formed of at least two coordinates on a PSNR and frame-rate plane.

9. The apparatus of claim 6, wherein the controller is configured to receive the ratio threshold value from the server.

10. The apparatus of claim 9, wherein the controller is configured to receive a report condition from the server, and

to reports, to the server, a result of measuring a quality of a video when the report condition is satisfied.

11. A method for allocating resources by a server, the method comprising:

transmitting, to a terminal, a target standard for quality of a video based on a Peak Signal to Noise Ratio (PSNR) or a frame-rate, and a ratio threshold value that is a standard of a ratio of correspondence between the quality of a video and the target standard;

receiving, from the terminal, a resource request based on the target standard and the ratio threshold value; and

allocating a resource to the terminal in response to the resource request.

12. The method of claim 11, wherein the target standard is set by a spatio-temporal range formed of at least two coordinates on a PSNR and frame-rate plane.

13. The method of claim 11, further comprising:

transmitting, to the terminal, a time threshold value indicating a maximum time in which the quality of video is allowed to be out of the target standard.

14. The method of claim 11, further comprising:

receiving, from the terminal, a request for allocation of an additional resource when a time greater than or equal to a predetermined time threshold value elapses while the quality of the video failed to satisfy the target standard.

15. The method of claim 11, further comprising:

transmitting a report condition to the terminal; and

receiving a result of measuring a quality of a video when the report condition is satisfied, from the terminal.

16. An apparatus for allocating resources, comprising:

a communication unit configured to transmit or receive a signal;

a controller configured to;

determine a target standard for a quality of a video based on a Peak Signal to Noise Ratio (PSNR) or a frame-rate, and a ratio threshold value that is a standard of a ratio of correspondence between the quality of a video and the target standard; and

transmit the target standard and the ratio threshold value to a terminal,

receive a resource request, based on the target standard and the ratio threshold value from the terminal, and

allocate a resource to the terminal in response to the resource request.

17. The apparatus of claim 16, wherein the target standard is set by a spatio-temporal range formed of at least two coordinates on a PSNR and frame-rate plane.

18. The apparatus of claim 16, wherein the controller is configured to transmit, to the terminal, a time threshold value indicating a maximum time in which the quality of video is allowed to be out of the target standard.

19. The apparatus of claim 16, wherein the controller is further configured to receive, from the terminal, a request for allocation of an additional resource when a time greater than or equal to a predetermined time threshold value elapses while the quality of the video failed to satisfy the target standard.

20. The apparatus of claim 16, wherein the controller is further configured to transmit a report condition to the terminal, and to receive a result of measuring a quality of a video when the report condition is satisfied, from the terminal.
