Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] From a technical point of view, video chat simply means that audio and video media streams are transmitted in real time on two established channels. This channel corresponds to the operating system level and consists of source IP, source port, destination IP, and destination port. and a socket identified by the quintuple of transport protocol type. It is full-duplex, its uplink channel is responsible for the output of local data, and its downlink channel is responsible for receiving remote data. When the TV is used as a communication entity, its downlink channel is specified by t...

Abstract

The invention discloses a video call switching method, an intelligent television terminal, a mobile terminal and a system. The video call switching method includes detecting video call establishing instructions of the intelligent television terminal; receiving channel switching request commands of users by the aid of the intelligent television terminal and acquiring current channel information of the intelligent television terminal and current media stream information; broadcasting the required-to-be-switched channel information and the required-to-be-switched media stream information by means of broadcast communication by the aid of the intelligent television terminal; receiving broadcast receiving switching requests by the aid of the mobile terminal in the same local area network, forging an IP (internet protocol) address of the mobile terminal by the aid of a local IP address of broadcast information of the intelligent television terminal and an IP address of a receiving side and transmitting the channel information and the media stream information to the receiving side by the aid of the mobile terminal. The video call switching method, the intelligent television terminal, the mobile terminal and the system have the advantages that an intelligent mobile phone in the same local area network can be disguised for a television set by the aid of IP address forging technologies and can assist the television set to carry out a voice input function, accordingly, the quality of the video calls can be enhanced, and the video call switching method, the intelligent television terminal, the mobile terminal and the system bring convenience for the users.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a video call switching method, a smart TV terminal, a mobile terminal and a system. Background technique [0002] With the popularity of smart TVs, the improvement of video processing capabilities of chips and the improvement of network infrastructure, video calls will usher in rare opportunities. TV-based large-screen, high-definition video chats are undoubtedly more popular with the public. However, TV video chat has the following limitations in voice calls: [0003] 1. The problem of audio collection. During chatting, the camera is usually placed on the TV, and the microphones of many cameras have limited collection capabilities. Users must be close to the TV to speak to the other party to hear clearly, and chatting is very tiring. And ordinary cameras usually do not have the noise reduction function, and there is usually low noise that is difficult to eliminate during...
