Problems solved by technology

[0004] In the current set-top box standby solution, the mainboard needs to be triggered by the user to enter the normal working state from the standby state. Therefore, when there is an important event that needs to be notified to the user urgently and the set-top box used by the user happens to be in the standby state, the user cannot obtain information through the set-top box.

Abstract

The embodiment of the invention discloses a digital television receiving terminal. The digital television receiving terminal comprises a main board, a position locking module, a microprocessor controller unit (MCU), and a main chip arranged on the main board and powered by the main board. The MCU is used for controlling the work state of the main board, the work state including standby state and normal work state. The position locking module is connected with the MCU, and is used for transmitting a wake-up signal to the MCU if receiving an emergency broadcast starting instruction when the main board is in the standby state. The MCU is used for starting the main board according to the wake-up signal, and controlling the main board to enter the normal work state. The main chip is used for acquiring emergency broadcast from a transport stream and playing the emergency broadcast after the main board enters the normal work state. The embodiment of the invention also discloses an emergency broadcast starting method and system. According to the invention, the digital television receiving terminal can start the emergency broadcast in the standby state.

Description

technical field [0001] The present invention relates to the communication field, in particular to a digital TV receiving terminal and an emergency broadcast starting method and system. Background technique [0002] With the successful launch of ChinaSat 9B (a broadcast and television live broadcast satellite), China's independent intellectual property rights satellite live broadcast system is officially in operation; usually, the set-top box supporting the live broadcast satellite has a built-in GPRS (General Packet Radio Service, general packet Wireless service) position locking module, by using the base station positioning function of the GPRS position locking module, it can decide whether to grant the set-top box the right to obtain program information through the live star. [0003] At present, the set-top box usually has a standby function, and the standby function of the set-top box is mainly realized through the standby of the main board; specifically, the set-top box...
