Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is further described:

[0023] Such as figure 1 , the present invention provides live video and monitoring functions between android PDAs with wifi or 3G connections.

[0024] Such as figure 2 , at the beginning of the program startup, it will send a message to the server with the public network IP, indicating its identity (sender / receiver). The public server will record the public IP and port corresponding to the PDA terminal in this session, and save it into the communication list. The two parties in the communication regularly pull the communication list, and the sender sends a message to the interested receiver, asking whether monitoring, live broadcast, etc. are needed. The receiver responds to the message, and if the message is legal, it can be monitored. Detailed monitoring of sender and receiver processes such as image 3 , 4 shown.

[0025] Such as image 3 , after the receiver sends...

Abstract

The invention relates to a mobile-phone PDA direct broadcasting system based on android. The system is characterized in that: a mobile phone terminal acquires a communicable PDA terminal list through a common network server; a sending terminal takes one terminal in the obtained list as a receiving terminal of video data and sends a connection request to the terminal; if the receiving terminal agrees to receive, a included camera is started, the video data is collected in real time and the collected video data is sent to a coding interface module; on a coding interface, a H264 algorithm is used to carry out video coding on the collected video data and the data is sent to an RTP sending module; the RTP sending module is used to send a data frame to a target PDA terminal; in an RTP receiving module, the receiving terminal decodes and plays the data frame. Compared to other systems, by using the system of the invention, real-time performance is high; a transmission rate is fast and the system can be used in different network environments.

Description

technical field [0001] The invention belongs to the technical field of network multimedia, relates to an android-based network streaming media live broadcast and monitoring system, and relates to a processing technology based on video real-time encoding and real-time transmission. Background technique [0002] Android was first released in 2008 and became popular all over the world in a short period of time. It had a huge impact on the smartphone industry and beat Symbian to become the mobile operating system with the largest market share in the world. Due to its huge market share and influence, smart phones have completely changed people's lives. At the same time, people's demand for smart phone services is also increasing. [0003] At present, the known live video broadcasting and monitoring systems all use wired transmission or 2.4GHZ wireless communication, and require corresponding computer / camera equipment for auxiliary support, and in daily life, people cannot satisf...
