Video live broadcast system facing to set-top box and PC of mobile phone and working method thereof

Abstract

The invention discloses a video live broadcast system facing to a set-top box and a PC of a mobile phone and a working method thereof and relates to the technical field of network multimedia television, the field of video transmission and the field of mobile phone communication, the system comprises a mobile phone as a video source of the video live broadcast system and a video server which is connected with a mobile phone antenna, wherein the mobile phone comprises a video acquisition unit, a mobile phone video encoding unit, an audio acquisition unit, an audio encoding unit, a writing unit,a mobile phone storage unit, an antenna transceiving unit and a deleting unit; and the video server comprises a network communication unit, a video decoding unit, an audio decoding unit, a data buffer unit, a server storage unit, an audio and video synchronization unit, a live broadcast command processing unit, a server video encoding unit, a server audio encoding unit, a live broadcast data transmitting unit and the like. The system and the working method thereof can realize the function of acquiring a video by applying the mobile phone and carrying out live broadcast facing to a variety of types of terminals, in particular to the set-top boxes through 3G wireless network, WIFI or GPRS wireless communication network.

Description

technical field [0001] The invention relates to the technical field of network multimedia television, the field of video transmission, and the field of mobile phone communication, and in particular relates to an architecture design scheme applied to the field of mobile phone video collection and monitoring. Background technique [0002] Mobile video live broadcast is to use a mobile phone with a camera to shoot video, and broadcast the video being shot live through the network. During the live broadcast, other people can watch the video through a TV set-top box with IP communication capabilities or a personal computer or mobile phone connected to the Internet. . [0003] At present, the technical difficulty of mobile live broadcast video lies in the weak computing and processing capabilities of mobile phones. There are 3G, WIFI, and GPRS network methods for mobile phones to connect to the Internet. Compared with wired connections, these methods are less reliable and have low...

Problems solved by technology

[0004] However, different types of user terminals have different requirements for video coding when watching live video, and the interaction protocols are also different. For example, when watching live video on a personal computer, it is required to obtain FLASH video, and when watching live video on a set-top box. The type is MPEG, 2, and the encoding type required when watching live video on a mobile phone is H263, but an existing live server can only send video streams of the same encoding type to all clients, which leads to each The service range of live video servers is extremely limited, making it difficult for video server suppliers to obtain more profits. Moreover, for clients, if they need video streams of different encoding types, they need to connect to different types of live video servers, so that the client's Very inconvenient to use
