Wireless content updating USB flash disk and implementation method thereof

Abstract

The invention discloses a wireless content updating USB flash disk and an implementation method thereof. The wireless content updating USB flash disk comprises a demodulation module, a DTMB radio frequency signal input port, a storage module, an SOC, a USB module and a FLASH chip. The input end of the demodulation module is connected with the DTMB radio frequency signal input port and is used for completing RF input to TS receiving to obtain a TS packet, and the output end of the demodulation module is connected with the SOC; the SOC is used for analyzing file directory information from the TS packet, and the SOC is further connected with the FLASH chip, the storage module and the USB module; the FLASH chip is used for storing a U-BOOT as well as a kernel program and an equipment tree file related to Linux; the storage module is used for writing the analyzed file directory information; and the USB module comprises a USB MASS Storage module and a slave interface, and the USB MASS Storage module is used for mapping the file directory information analyzed by the storage module into USB flash disk content and is connected with the advertising machine through the USB slave interface. According to the invention, the data broadcasting technology is utilized to carry out wireless real-time synchronous content updating on the USB flash disk inserted on the same type of advertising machine, and synchronous real-time content updating can be simultaneously carried out on a plurality of devices within the coverage range of data broadcasting.

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 a realization 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 machines have become more popular in the market. [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. It cannot be fully synchronized, which is not conducive to the synchronization of each advertising machine when playing advertising content. Contents of the invention [0004] The technical ...
