Abstract

A system and a method for split-rendering for persons with color weakness are proposed. The split-rendering method may include, by a service server, in response to a login of a user device, loading a color weakness profile corresponding to a user of the logging-in user device. The method may also include, by the service server, in response to the user being color-weak in accordance with the loaded color weakness profile, selecting one of a plurality of split-rendering servers. The method may further include, by the service server, transmitting a video content along with the color weakness profile to the selected split-rendering server, and by the service server, transmitting access information about the selected split-rendering server to the user device.

First claim

What is claimed is:

1 . A method for split-rendering for persons with color weakness, the method comprising:
by a service server, performing a color weakness test at an initial login of a user device; by the service server, storing a color weakness profile of a user of the user device based on a result of the color weakness test; by the service server, in response to a subsequent login of the user device, loading the color weakness profile corresponding to the user of the user device; by the service server, in response to the loaded color weakness profile, selecting one of a plurality of split-rendering servers; by the service server, transmitting a video content along with the color weakness profile to the selected split-rendering server; by the service server, transmitting access information about the selected split-rendering server to the user device; by the selected split-rendering server, generating a color-corrected video from the video content based on the color weakness profile; and by the selected split-rendering server, in response to accessing the selected split-rendering server using the access information by the user device, transmitting the color-corrected video to the user device, wherein the service server that provides the video content, which is not color-corrected, is a different entity from the selected split-rendering server that provides the color-corrected video.

2 . The method of claim 1 , further comprising:
after transmitting the color-corrected video to the user device, by the service server, updating the color weakness profile by re-performing the color weakness test in response to a request of the user device; by the service server, transmitting the updated color weakness profile to the selected split-rendering server; by the selected split-rendering server, regenerating a color-corrected video again by rendering the video content based on the updated color weakness profile; and by the selected split-rendering server, transmitting the regenerated color-corrected video to the user device.

3 . The method of claim 1 , further comprising:
by the service server, after performing the color weakness test, providing the user device with a sample video prepared by rendering based on the result of the color weakness test; and by the service server, in response to a feedback from the user device that the provided sample video is not properly corrected, repeating the color weakness test to obtain an updated test result.

4 . The method of claim 1 , wherein the color-corrected video comprises a real-time interactive content that communicates two-way with the user device and is created by rendering in real time by applying color correction.

5 . A system for split-rendering for persons with color weakness, the system comprising:
a plurality of split-rendering servers; and a service server configured to: perform a color weakness test at an initial login of a user device, store a color weakness profile of a user of the user device based on a result of the color weakness test, in response to a subsequent login of the user device, load the color weakness profile corresponding to the user of the user device, in response to the loaded color weakness profile, select one of the plurality of split-rendering servers, transmit a video content along with the color weakness profile to the selected split-rendering server, and transmit access information about the selected split-rendering server to the user device, the selected split-rendering server being configured to: generate a color-corrected video from the video content based on the color weakness profile, and in response to accessing the selected split-rendering server using the access information by the user device, transmit the color-corrected video to the user device, wherein the service server that provides the video content, which is not color-corrected, is a different entity from the selected split-rendering server that provides the color-corrected video.

6 . The system of claim 5 , wherein the service server is further configured to update the color weakness profile by re-performing the color weakness test in response to a request of the user device after transmitting the color-corrected video to the user device, and transmit the updated color weakness profile to the selected split-rendering server, and
the selected split-rendering server is further configured to regenerate a color-corrected video again by rendering the video content based on the updated color weakness profile, and transmit the regenerated color-corrected video to the user device.

7 . The system of claim 5 , wherein the service server is further configured to:
after performing the color weakness test, provide the user device with a sample video prepared by rendering based on the result of the color weakness test, and in response to a feedback from the user device that the provided sample video is not properly corrected, repeat the color weakness test to obtain an updated test result.

8 . The system of claim 5 , wherein the color-corrected video comprises a real-time interactive content that communicates two-way with the user device and is created by rendering in real time by applying color correction.
