Abstract

Embodiments of the present disclosure disclose a method and a device for dynamically controlling quality of a video displaying on a display associated to an electronic device is provided. The method comprises detecting current eye position of a user and identifying at least one region of interest (ROI) on a display screen of the display device based on the current eye position of the user. Then, the method comprises predicting next position of the eye based on at least one of the current eye position of the user or the at least one ROI. Also, the method comprises converting the SD video in to a high definition (HD) video displayed on the ROI on the display screen associated with the current and next position of the eye. Further, the method comprises displaying the HD video on the ROI of the display screen.

First claim

What is claimed is:

1. A method for dynamically controlling quality of a displayed video, comprising:
detecting, by a display device, a current eye position of an eye of a user;
identifying, by the display device, at least one region of interest (ROI) on a display screen of the display device based on the current eye position of the user;
predicting, by the display device, a next position of the eye of the user based on the current eye position of the user or the at least one ROI;
converting, by the display device, a standard definition (SD) video into a high definition (HD) video; and
displaying, by the display device, the HD video on the ROI of the display screen and the SD video in the non-ROI of the display screen, wherein detecting the current eye position of the user is performed by a motion detector, using optical eye tracking, using pattern mapping, or using a gaze-based interface technique and identifying the at least one ROI on the display screen is performed using binary space partitioning.

2. The method as claimed in claim 1 , wherein predicting the next position of the eye comprises:
receiving at least one of, one or more parameters associated with the SD video displayed on the display screen and at least one user profile;
predicting the next position of the eye based on the one or more parameters, the at least one user profile, or at least one resource; and
obtaining one or more frames of the SD video based on the predicted next position of the eye using an artificial neural network.

3. The method as claimed in claim 2 , wherein the one or more parameters are present coordinates on the display screen, plurality of motion vectors in one of neighboring pixels and objects, frame color, or color change in the frames of the SD video.

4. The method as claimed in claim 1 , wherein converting the SD video into the HD video further comprises performing spatial up-sampling at least one of a plurality of frames in the ROI or a plurality of frames in an at least one ROI associated with the next position of the eye, wherein the spatial up-sampling of the plurality of frames is performed by an interpolating technique.

5. The method as claimed in claim 1 , wherein displaying the HD video on the ROI of the display screen further comprises eliminating at least one of interference or a noise in the HD video.

6. A display device comprising at least one processor and a memory coupled to the processor which is configured to be capable of executing programmed instructions comprising and stored in the memory to:
detect a current eye position of an eye of a user;
identify at least one region of interest (ROI) on a display screen of the display device based on the current eye position of the user;
predict a next position of the eye of the user based on the current eye position of the user or the at least one ROI;
convert a standard definition (SD) video into a high definition (HD) video; and
display the HD video on the ROI of the display screen and the SD video in the non-ROI of the display screen, wherein detecting the current eye position of the user is performed by a motion detector, using optical eye tracking, using pattern mapping, or using a gaze-based interface technique and identifying the at least one ROI on the display screen is performed using binary space partitioning.

7. The display device as claimed in claim 6 , wherein the processor coupled to the memory is further configured to be capable of executing at least one additional programmed instruction to:
receive at least one of, one or more parameters associated with the SD video displayed on the display screen and at least one user profile; predict the next position of the eye based on the one or more parameters, the at least one user profile, or at least one resource; and
obtain one or more frames of the SD video based on the predicted next position of the eye using an artificial neural network.

8. The display device as claimed in claim 7 , wherein the one or more parameters are present coordinates on the display screen, plurality of motion vectors in one of neighboring pixels and objects, frame color, or color change in the frames of the SD video.

9. The display device as claimed in claim 6 , wherein the processor coupled to the memory is further configured to be capable of executing at least one additional programmed instruction to perform spatial up-sampling at least one of a plurality of frames in the ROI or a plurality of frames in an at least one ROI associated with the next position of the eye, wherein the spatial up-sampling of the plurality of frames is performed by an interpolating technique.

10. The display device as claimed in claim 6 , wherein the processor coupled to the memory is further configured to be capable of executing at least one additional programmed instruction to eliminate at least one of interference or a noise in the HD video.

11. A non-transitory computer readable medium having stored thereon instructions for transferring data in a storage cluster comprising executable code which when executed by a processor, causes the processor to perform steps comprising:
detecting a current eye position of an eye of a user;
identifying at least one region of interest (ROI) on a display screen of the display device based on the current eye position of the user;
predicting a next position of the eye of the user based on the current eye position of the user or the at least one ROI;
converting a standard definition (SD) video into a high definition (HD) video; and
displaying the HD video on the ROI of the display screen and the SD video in the non-ROI of the display screen, wherein detecting the current eye position of the user is performed by a motion detector, using optical eye tracking, using pattern mapping, or using a gaze-based interface technique and identifying the at least one ROI on the display screen is performed using binary space partitioning.

12. The non-transitory computer readable medium of claim 11 , wherein predicting the next position of the eye comprises:
receiving at least one of, one or more parameters associated with the SD video displayed on the display screen and at least one user profile;
predicting the next position of the eye based on the one or more parameters, the at least one user profile, or at least one resource; and
obtaining one or more frames of the SD video based on the predicted next position of the eye using an artificial neural network.

13. The non-transitory computer readable medium of claim 12 , wherein the one or more parameters are present coordinates on the display screen, plurality of motion vectors in one of neighboring pixels and objects, frame color, or color change in the frames of the SD video.
