TV motherboard and source code burning method

The invention relates to a television motherboard, in particular to a tuner, and can determine the television motherboard of the image system corresponding to the tuner according to the potential state of the plurality of pins of the tuner.

Advances in science and technology have led to the development of various electronic products, and the indispensable TV in daily life has evolved, such as the evolution from traditional analog TV to digital TV. Among them, the traditional analog TV signal transmission system accepts TV signals from a transmitting station in an analog modulation manner, such as analogy of single-sideband modulation or double-sideband modulation. Modulation method. As for the choice of the modulation method, there are different choices depending on the characteristics of the television signal to be transmitted.

However, the broadcast specifications of the TV signals designated by each country are also different. In terms of current status, the specifications of today's color TVs are based on NTSC, PAL, and SECAM, which are the major color TV specifications in the world. Among them, the United States, Canada, Mexico and other countries in the Americas, Japan and Taiwan adopt the NTSC system, mainland China and European countries adopt the PAL system, and France and its territories use the SECAM system. Moreover, in order to correspond to different image specifications, a tuner (whether a digital television or an analog television) needs to be installed with different tuners, that is, different image specifications correspond to different types of tuners, respectively, and burned. The source code to the tuner is also different.

However, at present, the industry can only manually identify which specifications a tuner belongs to, and cannot rely on the machine to automatically determine. Moreover, after determining which specification the tuner belongs to, the corresponding original code can be burned into the tuner. Therefore, once the specification of the tuner is misjudged, an error occurs in the subsequent source code burning program. More seriously, such errors are not easily discernible in appearance and can only be discovered in subsequent quality control procedures. After that, you must also "return" the TV with the original code to the machine that burned the original code, in order to re-burn the correct source code into the tuner. Over time, it not only takes time, but also adds additional manufacturing costs.

Therefore, the industry needs to cooperate with a tuner, and can determine the TV motherboard of the image system corresponding to the tuner according to the potential state of the plurality of pins of the tuner.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a television motherboard that can determine which image system a tuner corresponds to.
