Abstract

The invention discloses a vehicle-mounted digital image transmission system which comprises a first case, a gain adjusting port, a display screen, a key, a signal line, a radio frequency output interface, an HDMI output interface, an IP input interface, a video input interface, an audio input interface, a power transmission interface, a second case, a heat dissipation hole, a high-definition videoinput module, an H264 coding module, an antenna, an FPGA control unit module and a COFDM modulation module. The beneficial effects of the vehicle-mounted digital image transmission system are that the H264 coding module can achieve a high-end level on image quality and system delay when compared with similar product in the market, and lower video compression is achieved through shorter time underthe video compression technology of the same H264. The technology has the advantages of being suitable for high-speed movement and resisting multi-path interference. A wireless channel for a large data volume can be provided, and the data can be better compressed, so that the video signals can be transmitted faster, the data of different frequency signals can be transmitted to the maximum degree,and therefore different requirements can be met.

Description

technical field [0001] The invention relates to a digital image transmission system, in particular to a vehicle-mounted digital image transmission system, which belongs to the field of vehicle-mounted wireless video transmission. Background technique [0002] Wireless transmission refers to a way of data transmission using wireless technology. Wireless transmission and wired transmission are corresponding. With the development of wireless technology, the application of wireless transmission technology is more and more accepted by all walks of life. As a special way of use, wireless image transmission is gradually favored by the majority of users. Its convenient installation, strong flexibility, and high cost performance make monitoring systems in more industries adopt wireless transmission methods to establish connections between monitored points and monitoring centers. [0003] Because the traditional vehicle-mounted digital image transmission adopts the old-fashioned tr...
