Description

Technical Field

[0001] The present invention relates to the field of display control, and more specifically, to a display encoding device, a display system, a display encoding method and a display method. Background Art

[0002] With the development of applications such as cloud desktops, virtualization, and remote video conferencing, there is an increasing demand for using GPU display output and transmitting and displaying output signals remotely.

[0003] There are two main approaches to this demand: one is to use a SOC chip with encoding function, build an encoding system, realize the encoding conversion from HDMI input to network video stream, and then transmit it remotely through the network, and finally use a decoding device at the remote end to play and display it. Alternatively, a GPU with encoding function is selected, or a CPU is used to encode the local display output image, and then transmit it through the network, and finally use a decoding device at the remote end to play and display it.

[0004] The other method is to use a SOC chip with encoding function, build an encoding system, realize the encoding conversion from HDMI input to network video stream, and then transmit it remotely through the network, and finally use a decoding device at the remote end for playback and display.

[0005] These two methods have the following disadvantages:

[0006] The first disadvantage is that the encoding system is required to be controlled through the network, and the host computer cannot directly control the remotely transmitted display output. In order to control or set it, the host computer needs to access the network router and be able to access the SOC encoding system. The second disadvantage is that if the host computer output display resolution and the SOC encoding resolution setting are inconsistent, the remote display will be reduced or enlarged compared to the original output image, resulting in poor display effect, or adjusting the remote display settings requires adjusting the output display and SOC encoding settings separately.
