The content displayer device receives, decodes the data and smoothly plays the received data. The content controller device receives, decodes the data and plays the received data in synch with the content provider device. Additionally, a control command is generated by the content controller device to reply to the content provider device to manipulate operations of the content provider device.

Abstract: An encoding method of screen frame and its application of electronic devices, which rapidly detect motion regions and motionless regions from lossless screen frames captured by software, and then encode the motion regions with lower image quality while encode motionless regions with higher quality to display higher quality images and smooth video at a receiving end in real-time. Furthermore, the above-mentioned encoding method is optimized for lossless screen frames which does not need complicated operations of video encoder of prior art, such as motion estimation, motion compensation, etc., so that the method can be implemented with minor system resources and lower latency delay.

Abstract: A screen frame transmission method includes a transmitting end capturing screen frame data and audio data and transmitting the same to a receiving end, and detecting for a user's operation and outputting a mode switching signal; a receiving end buffering the screen frame data transmitted by the transmitting end, and according to the mode switching signal, switching to the operating mode or the video mode, wherein during the video mode, a longer playback period of the screen frame data are buffered, and during the operating mode, a shorter playback period of the screen frame data are buffered. According to the aforementioned method, during the video mode, the video may be played back smoothly and the video and the audio are synchronized; during the operating mode, a low latency delay control experience may be provided. A receiving device and screen frame transmission system realizing the above method are also disclosed.
