Abstract

The invention is suitable for the technical field of the digital television and provides a top box system for a digital television. The top box system of the digital television includes a top box of the digital television and a remote controller. The top box of the digital television includes a microprocessor chip and a bus interface. The top box of the digital television further includes a wireless network card. The wireless network card is connected with the microprocessor chip through the bus interface. The remote controller further includes a CPU and a wireless RF chip. The CPU of the remote controller controls the wireless RF chip to communicate with the wireless network card of the top box of the digital television through a wireless transmission protocol. The invention solves the problem that complex data lines are need to be connected when the top box of the digital television is used for carrying out the functions like video on demand, webpage browsing, network game, video and voice, etc., in the prior art.

Description

technical field [0001] The invention belongs to the technical field of digital television, in particular to a digital television set-top box system. Background technique [0002] At present, most of the digital TV set-top boxes produced and sold at home and abroad are one-way digital TV set-top boxes. figure 1 It shows the working principle diagram of the digital TV set-top box in the prior art. In the specific implementation process, the program information sent by the broadcasting and TV central office equipment is unidirectionally transmitted to the digital TV through the hybrid fiber coaxial network (Hybrid Fiber Coax, HFC) Set-top box, digital TV set-top box converts the received program information into analog signals that digital TV can receive and play, and input these analog signals to the user's digital TV, so as to realize the digital TV function of the TV. [0003] It is not difficult to see that the digital TV set-top box can only support one-way reception of d...
