Method and system for outputting and controlling LAN (Local Area Network) remote images, audios and videos

Abstract

The invention relates to a method for outputting and controlling LAN (Local Area Network) remote images, audios and videos. The method comprises the following steps of: selecting at least one control object at a control end, wherein the content of the control object can display in form of the images, the audios and the videos; finding out an output end by the control end; transmitting a control instruction to the output end through the control end; requesting part or all of display data of the control object to the control end through the output end as required; responding requests of the output end by the control end and transmitting the required control object display data to the output end; and executing the control instruction of the control end and displaying the content of the control object at the output end according to a prospective action after the output end receives the required control object display data and the control instruction. The invention further provides a system for outputting and controlling the LAN remote images, the audios and the videos. By the system, remote display can be realized, bandwidth consumption is small and operation experience is smoother.

Description

technical field [0001] The invention relates to a local area network remote image, audio and video output and control method and system, belonging to the technical field of computer networks. Background technique [0002] With the rapid development of the mobile Internet, personal families have undergone earth-shaking changes. In the past, there was only one desktop computer for smart digital devices at home. Today, it is very common for a household to have multiple smart digital appliances. Large-screen devices such as cloud TV, desktop computers, projectors, etc.; portable and compact devices such as smart phones, tablet computers, game consoles, etc. In this case, these intelligent digital appliances have established a local area network invisibly. With LAN, they can achieve more interesting things. This requires that the image, audio, and video on one device can be remotely output and remotely controlled on another device through a local area network. [0003] Tradi...

Problems solved by technology

Therefore, in this mode, it is impossible for the controlled terminal to feed back some status information such as playback progress to the control terminal, and it is impossible for the control terminal and the controlled terminal to form two-way interaction

In addition, traditional remote control devices often use infrared or other short-range transmission networks, which are not suitable for long-distance transmission networks such as home LAN or Internet (as long as the network speed is fast enough)
