Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The terms involved in the embodiments of the present invention are explained as follows:

[0036] Multicast: A network communication in which a single sender corresponds to multiple receivers. In multicast technology, by transmitting a single information flow to multiple receivers, it can reduce the number of receivers who listen to or view the same resource at the same time. Network traffic.

[0037] TCP: Transmission Control Protocol, which is a connection-oriented, reliable, byte stream-based transport layer communication protocol.

[0038] UDP: User Datagram Protocol, a connectionless ...

Abstract

The present invention discloses a method and system for realizing direct broadcast projection screen based on multicast on an intelligent television. The method comprises the following steps: S1, a mobile client opens a multicast function and monitors a UDP port; S2, a television server opens a multicast function and monitors the multicast broadcast and the UDP port; S3, the mobile client sends a search command request to the IP address of the multicast broadcast in the multicast broadcast mode; S4, the television server sends a UDP response command to the mobile client, the mobile client analyzes the UDP response command to obtain a television server device list; S5, the mobile client receives a user selection result from the television server device list, after the selection, the mobile client sends a projection screen request in the UDP mode to the selected television server, and the television server analyzes the received projection screen to obtain projection screen information and perform playing according to the direct broadcast flow address in the projection screen information. The method and system for realizing direct broadcast projection screen based on multicast on the intelligent television can rapidly realize projection screen, and the user experience effect is good.

Description

technical field [0001] The present invention relates to the technical field of screen projection and playback on smart TVs, and in particular to a method and system for realizing live projection on a smart TV based on multicast. Background technique [0002] In the prior art, there are certain defects in the method of projecting the live video played on the mobile phone or tablet to the smart TV for display and playback. The existing methods include DLNA protocol, AirPlay and other technologies. Among them, the DLNA protocol is a set of interconnection protocols between PCs, mobile devices, and consumer appliances initiated by Sony, Intel, and Microsoft. AirPlay is a wireless technology developed by Apple, which can wirelessly transmit pictures, audio, and video on Apple devices to devices that support AirPlay through WiFi. [0003] Most of these screen projection and control methods on the market are based on UDP broadcasting. UDP broadcasting will not only waste bandwidth...
