Abstract
The invention provides a wireless video transmission system based on general packet radio service (GPRS), which aims at solving the problem that a traditional video transmission system adopts a wiring mode to transmit data, and wiring is difficult under the condition of poor environment. A video acquisition module of the wireless video transmission system is controlled by an object module assembly program 5910 (OMAP5910) main control chip to acquire external video information through a complementary metal-oxide-semiconductor transistor (CMOS) colored image sensor chip 0V7640 and converts the video information into electrical signals which are sent to a G07007 video coding chip. The G07007 video coding chip performs video compression on the acquired video information and sends the information to a synchronous dynamic random access memory (SDRAM) for temporary storage. Under the control of the OMAP5910 main control chip, video data which are compressed and coded are sent out through a GPRS module, and the compressed and coded video data received by a GPRS module at the other end are transmitted to a display device.
Description
Technical field
The present invention relates to electronic technology field, a kind of wireless video transmission system based on GPRS is provided.
Background technology
Vision is human to obtain the topmost means of information from the Nature, and the mankind have 60% information to obtain through vision.Video is liked by people as a kind of exchange way the most intuitively.Real-time video transmission technologies has also obtained very big development under the promotion of this demand.But traditional Video transmission system utilizes the main part of PC as system, has used various cables to realize the transmission of video simultaneously, makes Video transmission system receive great restriction.Use PC as major part, make that the volume of system is very big, cost is very high.And the use cable, it is very inconvenient that the system that then makes moves, also cable also very easily be damaged, a bit damaging of cable will make system not work.Along with the development of GPRS technology and the maturation of embedded design technology, this has facilitated the scheme that a kind of new wireless video transmits, and is the basis, utilizes the Embedded System Design technology to realize the transmission of wireless video with GPRS technology and video coding and decoding technology exactly.
Summary of the invention
The objective of the invention is to through providing a kind of simple in structure, a kind of wireless video transmission system with low cost based on GPRS.
The present invention is for realizing that above-mentioned purpose adopts following technical scheme:
A kind of wireless video transmission system based on GPRS is characterized in that comprising:
Video acquisition module: comprised CMOS color image sensor chip 0V7640, will gather extraneous video information and be translated into the signal of telecommunication through CMOS color image sensor chip 0V7640;
The G07007 video coding chip: the vision signal to image capture module collects is carried out video compression coding;
GPRS module: as the Transmit-Receive Unit of video sending end and video receiver video data;
System power supply: the operating voltage that needs is provided for system;
OMAP5910 master control chip: the collection of control of video signal, transmission and reception;
Said video acquisition module is gathered extraneous video information and is translated into the signal of telecommunication through CMOS color image sensor chip 0V7640 under the control of OMAP5910 master control chip and sends the G07007 video coding chip to; It is temporary that the G07007 video coding chip carries out giving SDRAM behind the video compression coding to the vision signal that collects; The video data that under the control of OMAP5910 master control chip, will pass through compressed encoding then sends through the GPRS module, and the GPRS module of the other end sends it to display device after receiving the video data of compressed encoding.
OMAP5910 master control chip adopts built-in Linux operating system, the collection of control of video signal, transmission and reception.
The present invention has following beneficial effect:
The present invention adopt the GPRS wireless transmission method to video acquisition to data transmit, not only with low cost, and can under the abominable situation of physical features environment, carry out reliable video Data Transmission.
