The attribute matrix includes the number of display parameters for the display of each video playback device, identification information, general display parameters supported by the graphics card manufacturer (e.g. Samsung, Nvidea, etc.), each graphics card manufacturer specific parameter, And maximum threshold, display type, and the like.

In addition, the cloud display management server can obtain the VCP attribute from the video playback apparatus. The cloud display management server can create or modify attribute matrices based on VCP attributes.

In step 740, the cloud display management server may determine the display parameters based on the display information and attribute matrix. The cloud display management server can analyze the received display information and the extracted attribute matrix. The cloud display management server can determine whether the display parameter needs to be adjusted based on the analysis result, and optimize the display parameter according to the determination result.

At step 750, the cloud display management server may send display parameters to at least one video playback device. The cloud display management server may determine the communication mode and transmit the display parameters to the at least one video playback device through the multiple pipeline layers. The communication mode may be one of a master transmission mode, a master reception mode, a slave transmission mode, and a slave reception mode.

In addition, the cloud display management server may instruct the video playback device to directly optimize display parameters for a predetermined time.

The cloud display management server may also decode the optimized display parameters and transmit the decoded display parameters to the at least one video playback device.

8 is a flowchart showing a method in which a video reproduction apparatus applies display parameters.

In step 810, the image reproducing apparatus can transmit the display information to the cloud display management server. When the image reproducing apparatus has the calculation processing capability, the image reproducing apparatus can calculate the image quality information according to the current display parameter. The image quality information may be calculated according to a preset formula and may be calculated based on parameter values provided by the graphics card manufacturer. The calculated image quality information may be transmitted to the cloud display management server together with the identification information, the current display parameter value, and the surrounding environment information. The cloud display management server can optimize the display parameters based on the display information.

In step 820, the image reproducing apparatus can receive the display parameters. The video reproduction apparatus can receive optimized display parameters from the cloud display management server based on the transmitted display information. The display parameters may be received via multiple pipeline layers. Further, the image reproducing apparatus may receive a command list or an instruction list including display parameters.

Further, the video playback apparatus can decode the received command list. For example, the video playback apparatus may decode the received display parameters based on an I2C (Inter-Integrated Circuit) protocol.

Further, the image reproducing apparatus may receive the decoded display parameter.

Further, the image reproducing apparatus may receive an instruction to directly optimize the display parameter from the cloud display management server for a predetermined time.

In step 830, the image reproducing apparatus can apply the display parameters. The image reproducing apparatus can apply the decoded display parameter to the display.

Further, when receiving an instruction to directly optimize the display parameters from the cloud display management server for a predetermined time, the image reproducing apparatus can directly transmit the display information to the cloud display management server for a predetermined time, have.

The image reproduction apparatus and the cloud display management server can repeatedly optimize display parameters in real time by exchanging display information and optimized display parameters. Therefore, the image reproducing apparatus can provide a viewer with a better viewing experience.
