Abstract

The invention is suitable for the technical field of televisions and provides a digital television all-in-one machine and a method for searching channels. The digital television all-in-one machine comprises an MCU, a memory and a tuning and demultiplexing module, wherein the MCU is used for reading a NIT initial frequency corresponding to an area in the memory according to the area selected by a user to input the NIT initial frequency into the tuning and demultiplexing module, and setting the frequency of the tuning and demultiplexing module into the NIT initial frequency; the tuning and demultiplexing module is used for receiving a television signal corresponding to the NIT initial frequency input by the MCU, acquiring an NIT table from the received television signal and searching the channels according to frequency information in the NIT table; and the memory is used for storing a preset NIT initial frequency list.

Description

technical field [0001] The invention belongs to the technical field of digital television, and in particular relates to a digital television integrated machine and a method for quickly searching channels thereof. Background technique [0002] Digital TV is being promoted all over the country and will eventually replace analog TV. However, due to history and national conditions, digital TV operators in various cities and regions have not entered this field under completely unified standards and regulations. PSI The transmission forms of / SI (Program Specific Information / Service Information, program definition information / service information) are not exactly the same, including the placement frequency and organization form of these information may also be different. Even the PSI / SI of digital TV signals sent by different operators in the same city may be inconsistent. [0003] Because the existing business model of digital TV all-in-ones is similar to ordinary flat-screen TVs...
