Abstract
The invention relates to a radio online real-time broadcasting system, in particular to a radio video streaming media broadcasting system constructed by an RTSP (Real-Time Streaming Protocol) and an RFCOMM (Radio Frequency Communication) protocol. The RTSP is the multimedia streaming protocol used for controlling sound or images; and the RFCOMM protocol provides serial data transmission by providing serial port simulation on an L2CAP layer connected to a lower layer stacked by Bluetooth protocols. The constructed media stream system can realize wire communication in a radio system.
Description
Technical field
The present invention relates to a kind of wireless online real-time playing system, by RTSP and RFCOMM agreement framework radio video streaming media Play System.
Background technology
RTSP (Real Time Streaming Protocol), real time streaming transport protocol is an application layer protocol in the ICP/IP protocol system, by the IETF RFC standard of Columbia University, Netscape and the submission of RealNetworks company.This protocol definition one-to-many application how transmit multi-medium data by IP network effectively.
The RFCOMM agreement can be imitated the state of setting of serial cable line and RS-232 serial port, is used to provide Serial Data Transfer Mode.RFCOMM can be connected to the lower level of bluetooth protocol stack by the L2CAP layer.
By above two agreements, can set up radio flow media system by let us; Can convert the stream medium data of RTSP agreement control to by RFCOOM can be by the bluetooth equipment recognition data.The media stream real-time Play System just can expand to wireless domain like this.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of based on RTSP and RFCOMM agreement, the video stream media real-time online Play System in wireless network.
This wireless medium streaming system is based on that RTSP and RFCOMM agreement carry out, and RTSP is the multimedia series flow agreement that is used for controlling sound or image, and allows simultaneously a plurality of crossfire demands controls; Do like this except reducing the network consumption of server end, more and then support video conference (Video Conference) in many ways.
Network communication agreement used during media flow transmission is TCP and udp protocol, server end can select to use TCP or UDP to transmit streamed content voluntarily, grammer and running are similar with HTTP 1.1, but lay special stress on time synchronized not, so relatively can tolerate network delay.Because it is similar to the function mode of HTTP1.1, so acting server＜Proxy〉get function＜Cache soon be applicable to RTSP too, and has guide function again because of RTSP, visual actual loading situation is changed the server that service is provided, the redundancy of media stream server is well guaranteed, cause delay in same server to avoid excessive load centralization.
The RFCOMM agreement is connected to the lower level of bluetooth protocol stack by serial port emulation is provided at the L2CAP layer, and Serial Data Transfer Mode is provided.In communication section (equipment is between another equipment), play direct-connected Bluetooth link, thereby become the data transaction of Streaming Media the wireless device can recognition data, the media streaming system that gets up of framework just can be realized and wire communication in wireless network like this.
The invention has the beneficial effects as follows, can provide the service of access stream media play for wireless device terminal by this Media Stream of framework Play System.
Claims (3)
1. this wireless medium streaming system is based on that RTSP and RFCOMM agreement carry out.RTSP is the multimedia series flow agreement that is used for controlling sound or image, and allows simultaneously a plurality of crossfire demand controls; The control of RTSP can reduce the network consumption of server end, and supports video conference (Video Conference) in many ways.RTSP has guide function again, and visual actual loading situation is changed the server that service is provided.
2. used network communication agreement is TCP and udp protocol during media flow transmission, server end selects to use TCP or UDP to transmit streamed content voluntarily, grammer and running are similar with HTTP 1.1, but lay special stress on time synchronized is not done like this and can be tolerated network delay.
3.RFCOMM agreement is connected to the lower level of bluetooth protocol stack by serial port emulation is provided at the L2CAP layer, and Serial Data Transfer Mode is provided.In communication section (equipment is between another equipment), play direct-connected Bluetooth link, thereby become the data transaction of Streaming Media the wireless device can recognition data, the media streaming system that gets up of framework just can be realized and wire communication in wireless network like this.
