Embodiment 1

[0051] Such as figure 2 As shown, a method for automatically identifying the tuner and demodulator of a digital TV set-top box. After the set-top box starts normally, it can automatically identify the driver program corresponding to the model of the tuner and demodulator being used and complete the driver loading. Steps include:

[0052] S1: start the set-top box;

[0053] S2: Read the configuration file in the memory, check whether there is correct tuner and demodulator configuration information, if yes, execute step S12; if not, execute step S3;

[0054]S3: Get the tuner list from the NIM driver library, set the value of i to 1; i is a positive integer variable, representing the serial number of the tuner and / or demodulator in the tuner and / or demodulator list;

[0055] S4: Determine whether the value of i is greater than the total number m recorded in the tuner list; m is a natural number, indicating the total number of tuners in the tuner list; if not, send the address ...

Embodiment 2

[0067] Such as image 3 Shown, the method for automatically identifying digital TV set-top box tuner and demodulator, its steps include:

[0068] S1: start the set-top box;

[0069] S2: Read the configuration files of the tuner and demodulator in the memory, check whether there is correct tuner and demodulator configuration information, if yes, execute step S12; if not, execute step S3;

[0070] S3: Obtain the demodulator list from the NIM driver library, set the value of i to 1; i is a positive integer variable, representing the serial number of the tuner and / or demodulator in the tuner and / or demodulator list;

[0071] S4: Determine whether the value of i is greater than the total number n recorded in the demodulator list; n is a natural number, indicating the total number of demodulators in the demodulator list; if so, send the i-th demodulator in the demodulator list address to the I2C bus, and execute step S5; otherwise, it prompts failure and ends the process;

Abstract

The invention relates to a method for automatically identifying a tuner and a demodulator of a digital television STB (Set Top Box). When the STB is designed, drivers corresponding to the tuner and the demodulator in different sizes are packaged according to a uniform interface, and a packaged result is introduced into an NIM (Network Installation Manager) driver base. After the STB is normally started, the drivers corresponding to the sizes of the tuner and the demodulator can be automatically identified through tuner and demodulator configuration files stored in a memory and a tuner list and a demodulator list in the driver base, and the driver loading is finished. According to the method, the drivers for the tuner and the demodulator in different sizes can be efficiently integrated and the drivers can be quickly and automatically identified and loaded, so as to unify software drivers of a channel module.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method for automatically identifying a tuner and a demodulator of a digital television set-top box. Background technique [0002] With the advancement of the triple play process and the continuous promotion of digital TV services, the application of digital TV set-top boxes is becoming more and more popular, and the types are becoming more and more diverse. Since there is no unified standard, the solutions of various set-top box design manufacturers and set-top box manufacturers The hardware models used are also different. For example, there are many types of set-top box tuners and demodulators, and different types of hardware products correspond to different drivers, which brings a lot of inconvenience to the R&D, design and production of digital TV set-top boxes. The main problems encountered so far are summarized as follows: [0003] 1. The driver integration wor...
