Abstract

The system includes following parts: ordered connected tuner, A/D converter, and digital broadcast decoder (DBD); decoded data memory (DDM) and display connected to the decoder respectively; information processor (IP) connected to DDM, printer interface circuit (PIC) connected to the display and IP respectively; and microprocessor for controlling DBD, DDM, the display, IP, and PIC. Through processing, the system converts the received ground digital broadcasting graphics context information below 30MHZ into printing information receptible by printer as well as through PIC, transfers the graphics context information to printer to print out needed graphics context for saving. Advantages are: not using computer, practical, shortcut, and low cost.

Description

technical field [0001] The present invention relates to a real-time global digital audio broadcasting receiver, in particular to a graphic printing system and graphic printing method of a terrestrial digital audio broadcasting receiver below 30MHZ. The information is received, and the data is processed by the printer, and then sent to the printer to achieve the purpose of printing out the graphic content in the global digital broadcast receiver. Background technique [0002] At present, with the promotion of the global digital radio (DRM: Digital Radio Mondiale) technology, the traditional medium and short wave analog radio is being replaced by the global digital radio. While the global digital broadcasting technology provides FM-quality sound broadcasting, it can also carry data service information including images, texts, and web pages for audiences to watch. And the audience is very interested in a certain scene when listening to the program often, but this scene often p...
