Abstract

An electronic device for processing and playing a video transmitted from an input device is provided. The electronic device includes video processors and a processor. The video processors are configured to perform processing operations based on a test video including frames received from the input device to generate a sampling video including the frames, where each of the frames include at least one pattern. The processor is configured to receive the sampling video, determine whether the sampling video is output normally or not and an output order of each of the plurality of frames on the sampling video, based on the at least one pattern, and determine whether an error occurs in at least one of the input device and the plurality of video processors, based on the output order of each of the plurality of frames and whether the sampling video is output normally or not.

First claim

1 . An electronic device for processing and playing a video transmitted from an input device, the electronic device comprising:
a plurality of video processors configured to perform processing operations based on a test video including a plurality of frames received from the input device to generate a sampling video including the plurality of frames, where each of the frames includes at least one pattern; and a processor configured to receive the sampling video, wherein the processor is configured to determine an output order of each of the plurality of frames of the sampling video and whether the sampling video is output normally or not, based on the at least one pattern, and wherein the processor is further configured to determine whether an error has occurred in at least one of the input device and the plurality of video processors, based on the output order of each of the plurality of frames and whether the sampling video is output normally or not.

2 . The electronic device of claim 1 , wherein the processor is configured to
check an output order of a current frame among the frames, based on a first pattern of the at least one pattern indicating the output order of each of the plurality of frames, and when the output order corresponding to the current frame is not sequential to an output order corresponding to a previous frame, determine that an output order error has occurred.

3 . The electronic device of claim 2 , wherein the first pattern comprises a binary pattern.

4 . The electronic device of claim 1 , wherein the processor is configured to compare a predetermined pixel value with a pixel value of a pixel of a predetermined position among pixels implementing a second pattern representing a plurality of colors and determine whether the sampling video is output normally or not, based on the comparison.

5 . The electronic device of claim 4 , wherein the at least one pattern comprises the second pattern,
wherein the second pattern included in each of the plurality of frames is the same.

6 . The electronic device of claim 1 , wherein each of the plurality of video processors comprises an input module configured to standardize the test video to generate a first sampling video, and
the processor is configured to receive the first sampling video from the input module and, when at least one of an output order error of the first sampling video and an abnormal output of the first sampling video occurs, determine that an error occurs in the input device.

7 . The electronic device of claim 1 , wherein the processor is configured to
receive the sampling video from each of the plurality of video processors and determine whether at least one of an output order error and an abnormal output of each of the sampling videos occurs, and determine whether an error occurs in a target video processor among the video processors, based on whether an error has occurred in one of the video processors which performs the processing operation on the test video prior to the target video processor outputting a sampling video where at least one of the output order error and the abnormal output has occurred.

8 . The electronic device of claim 1 , wherein the processor is configured to
receive a final sampling video from a final video processor among the video processors that performs the processing operation last among the plurality of video processors and determine whether an error has occurred in at least one of the input device and the plurality of video processors, based on an output order of each of a plurality of frames of the final sampling video and whether the final sampling video is output normally or not.

9 . The electronic device of claim 8 , wherein the processor is configured to, when an output order error of each of a plurality of frames of the final sampling video does not occur and a normal output of the final sampling video has occurred, determine that no error has occurred in the input device and the plurality of video processors.

10 . The electronic device of claim 8 , wherein the processor is configured to, when at least one of an output order error and an abnormal output of the final sampling video has occurred, determine whether an error has occurred in at least one of the input device and the plurality of video processors, based on whether an error has occurred in a video processor among the video processors which performs the processing operation on the test video prior to the final video processor.

11 . The electronic device of claim 1 , wherein the processor is configured to determine whether the test video is rotated or not, and when the test video is rotated, determine an output order of each of the plurality of frames on the sampling video and whether the sampling video is output normally or not, based on the at least one pattern and an angle by which the test video is rotated.

12 . The electronic device of claim 1 , further comprising a display panel configured to display the video,
wherein the processor is configured to, when an error occurs in at least one of the input device and the plurality of video processors, control the display panel to display a notification indicating that the error occurs.

13 . An electronic device for processing and playing a video transmitted from an input device, the electronic device comprising:
an input module configured to receive at least one test video from the input device, each test video including a plurality of frames including a first pattern and a second pattern; and a processor configured to check an output order of each of the plurality of frames included in at least one sampling video generated from performing a processing operation on the at least one test video, based on the first pattern, check whether the at least one sampling video is output normally, based on the second pattern, and determine whether an error occurs in at least one of the input device and the electronic device, based on the output order and whether the at least one sampling video is output normally.

14 . The electronic device of claim 13 , wherein the processor is configured to receive a first sampling video of the at least one sampling video from the input module, where the at least one test video is standardized to generate the first sampling video, and determine that an error occurs in the input device when at least one of an output order error of the first sampling video and an abnormal output of the first sampling video occurs.

15 . The electronic device of claim 14 , further comprising a scaler configured to perform a scaling operation on the first sampling video to generate a second sampling video,

16 . The electronic device of claim 15 , wherein the processor is configured to determine that an error occurs in the scaler, when at least one of the output order error and the abnormal output of the second sampling video occurs and the output order error and the abnormal output of the first sampling video do not occur.

17 . The electronic device of claim 15 , further comprising an image quality processor configured to perform an image quality processing operation on the second sampling video to generate a final sampling video,
