A kind of wireless update content U disk and its realization method

Abstract

The invention discloses a U-disk of wireless update content and a realization method thereof, comprising a demodulation module, a DTMB radio frequency signal input port, a storage module, an SOC, a USB module and a FLASH chip. The input terminal of the demodulation module is connected to the DTMB radio frequency signal input port, which is used to complete the RF input to the TS reception, and obtain the TS packet. The output terminal of the demodulation module is connected to the SOC; the SOC is used to complete the parsing of the file directory information from the TS packet. , SOC is also connected with FLASH chip, storage module and USB module respectively; FLASH chip is used to store U-BOOT and Linux-related kernel programs and device tree files; storage module is used to write the parsed file directory information; USB module Including a USB MASS Storage module and a slave interface, the USB MASSStorage module is used to map the file directory information parsed by the storage module into the content of the U disk, and connect to the advertising machine through the USB slave interface. The invention utilizes the data broadcasting technology to update the content of the U disk inserted in the same type of advertising machine in real time wirelessly, and within the scope covered by the data broadcasting, can simultaneously update the content of multiple devices in real time.

Description

technical field [0001] The invention belongs to the technical field of digital television, and in particular relates to a U-disk for wirelessly updating content and an implementation method thereof. Background technique [0002] With the development of science and technology, the existing information media are not only newspapers, radio, television or the Internet. As a new information carrier, advertising machine has become more popular in the market. [0003] The content update of the advertising machine is generally by replacing the built-in storage device, connecting the computer or manually copying the U disk, but this method will be very troublesome if there are a large number of advertising machines, consume a lot of labor resources, and the update time is limited. First, it cannot be completely synchronized, which is not conducive to the synchronization of each advertising machine when playing the advertising content. SUMMARY OF THE INVENTION [0004] The technic...

[0003] The update of the content of the advertising machine is generally done by replacing the built-in storage device, connecting the computer or manually copying the U disk, but this method will be very troublesome if there are a large number of advertising machines, consuming a lot of labor resources, and the update time is limited. First, then, can not be fully synchronized, which is not conducive to the synchronization of each advertising machine when playing advertising content
