Embodiment Construction

[0013] according to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 , the present invention provides a kind of decoding method of digital multimedia broadcasting receiver electronic program guide, and it comprises the following steps: first step, at first the broadcasting signal of digital multimedia broadcasting enters the RF module of digital multimedia broadcasting receiver and converts into intermediate frequency signal; In the second step, the intermediate frequency signal after A / D conversion is sent to the baseband decoding module of the digital multimedia broadcasting receiver for channel decoding and audio decoding, and the baseband decoding module sends the information in the fast information channel (FIC) to the processor The baseband decoding module adopts ID200DAB baseband decoding chip, and the processor is MSP430F147 processor, which is a FLASH type 16-bit RSIC instruction set microcontroller. The MSP430F147 processor can provide 32kb F...

Abstract

The invention discloses a method for decoding an electronic program guide of a digital multimedia broadcast receiver. The method comprises the steps as follows: firstly, a signal of a digital multimedia broadcast enters into the RF module of the digital multimedia broadcast receiver to be converted into an intermediate-frequency signal; secondly, the intermediate-frequency signal is treated with A/D conversion to become an intermediate-frequency digital signal which is then sent into a baseband decoding module for carrying out channel decoding and audio decoding, meanwhile, the baseband decoding module sends information in a fast information channel into a processor to be treated with software decoding; thirdly, the software decoding is carried out; fourthly, decoded electronic program guide data is sent to a display device.

Description

technical field [0001] The invention relates to a decoding method of an electronic program guide of a digital multimedia broadcasting receiver. Background technique [0002] The current digital multimedia technology is developing day by day, but when people watch or listen to digital multimedia broadcasting, there are many programs and types of programs, but there is no navigation mechanism for program information preview, so it is difficult for users to find the programs they care about. Checking the relevant information of the program and classifying the program will bring a lot of inconvenience to the user to select the program. Contents of the invention [0003] The invention provides a decoding method of an electronic program guide of a digital multimedia broadcasting receiver, which can decode the electronic program guide and is convenient for users to watch. [0004] The present invention adopts the following technical solutions: a decoding method for the electroni...
