Problems solved by technology

When the audio and video data and control information are transmitted on the same network channel, the control information will compete with the audio and video data for bandwidth, especially when the wireless access point is connected to multiple terminals, it will form a bandwidth bottleneck. In this case, the Delays in control information can occur

Abstract

The invention relates to a multi-screen interactive system, comprising at least two intelligent terminals. Each intelligent terminal comprises an audio and video data receiving and transmitting module and a control information receiving and transmitting module, wherein the audio and video data receiving and transmitting module is used for receiving and transmitting audio and video data via a first information channel, and the control information receiving and transmitting module is used for receiving and transmitting control information via a second information channel different from the first information channel. The multi-screen interactive control system makes full use of transmission information channels and reduces transmission delay of the control information. The invention further provides an intelligent terminal which is applicable to multi-screen interactive control technology, and a multi-screen interactive control method.

Description

technical field [0001] The invention relates to an information exchange technology between intelligent terminals, in particular to a multi-screen interactive system, an intelligent terminal and a multi-screen interactive control method. Background technique [0002] With the advancement of science and technology, smart terminals, such as smart TVs, smart phones, tablet computers, etc., have achieved great development. And applications put forward higher and higher requirements for the interactive capabilities of smart terminals. [0003] At present, the industry has developed a multi-screen interaction technology to realize the interaction between multiple smart terminals. The existing multi-screen interactive technology is a single-mode screen transmission (also called "moving screen") mode, that is, one smart terminal is used as the host, and other smart terminals are used as slaves, and the host pushes the displayed content to the slaves for display. [0004] To achieve...
