Abstract: A method and a system of real-time variable refresh rate video processing for ambient light rendering, comprise: capturing a HDMI video signal and converting the HDMI video signal into a RGB signal; obtaining frame rates X1, X2, and X3 of a current video source by detecting a field frequency signal V-SYNC; setting a constant frame rate or a variable frame rate by user; setting the constant frame rate by the user and the constant frame rate is set as N, obtaining the constant frame rate N set by the user, outputting a color rendering data of the fixed frequency in real time through data processing; setting the variable frame rate by the user and the variable frame rate is set as M, obtaining the variable frame rate M set by the user, and outputting a color rendering data of a variable frequency in real time through the data processing.

Abstract: A system and method for achieving synchronized audio and image control of lighting is provided. The system includes: audio-image information acquisition and processing software of an audio-image playback device for achieving acquisition, analysis, and processing of audio and screen image information, and encapsulating the audio and screen image information into a synchronization control instruction according to a predetermined control strategy; a cloud server; and a lighting device for receiving the synchronization control instruction transmitted from the audio-image information acquisition and processing software to separate out audio and screen image color control instructions, and controlling colors and rhythm changes of a lamp according to a predetermined control strategy.

Abstract: A method of regional color processing based on video content and a system using the same are provided, comprising: step 1: dividing a data area; step 2: denoising pixel video data; step 3: generating a representative value of small block; step 4: detecting a video scene type; step 5: smoothing of the representative value of the small block; step 6: dark block fading processing; step 7: HDR custom compensating/definition restoring; and step 8: generating a representative value of the large block. It divides the video source data into small blocks or large blocks according to the rendering granularity of the ambient light, and implements algorithms such as noise reduction, smooth processing and adaptive compensation according to the video format and content, and the lighting rendering can follow the video signal in real time, which can effectively reduce the sudden change of rendering light and bring users more soothing experience.

Abstract: A protection method in a packet transport network is provided. A protection path is established for a service data flow borne on a shared protection ring in the method, where the protection path includes a wrapping protection path and a steering protection path. Firstly, a first service data flow is sent through the wrapping protection path. Then, a service data flow node stops sending a second service data flow subsequent to the first service data flow to the wrapping protection path, and buffers the second service data flow. When the first service data flow completely passes by the service data flow node again, the buffered second service data flow is switched from the wrapping protection path to the steering protection path.
