Abstract

The utility model discloses a wireless digital set-top box, which is composed of a TV, a system control module, an external interface module, an audio frequency control module, a video control module, a pattern control module, an overlay controller, a network interface, etc., wherein, the system control module and the external interface module are connected with the audio frequency, the video and the pattern control modules on a user's terminal through coaxial cables. The utility model is characterized in that the network interface terminal is provided with a wireless modem into a wireless network interface. The utility model effectively solves the defect that in the application of the existing set-top box, lines are needed to be laid on a user's terminal and the user's interior trim is destroyed, so as to realize the communication method of wireless broadband Internet.

Description

Wireless digital set-top box

Technical field

The utility model relates to the broadband network system application, particularly a kind of nil set-top box.

Background technology

Present broadband user all be basically by coaxial cable with telephone wire or be connected 5 class lines, set-top box is the capital equipment that the broadband user is used for connecting the internet.The structural principle of a set-top box is equivalent to the computer (PC) of a simplification, also partly forms by central processing unit (CPU), internal memory, I/O control (I/O), multimedia player etc., and be to overlap very mature technique.But the greatest problem that present set-top box exists and be not; Need be at user's family laying-out, and the user can not arbitrarily move.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of wireless digital set-top box of realizing the Internet with wireless mode is provided.

The purpose of this utility model is to be achieved by the following scheme: be made of television set, system control module, Peripheral Interface module, audio frequency control module, video control module, figure control module, overlay controller and network interface etc., wherein said system control module, Peripheral Interface module are connected by the coaxial cable formation with audio frequency, video and the figure control module of user side, it is characterized in that: be provided with radio modem at the network interface end and constitute radio network interface.

The utility model has solved the defective of laying fixed line and destruction user interior decoration at user side because adopted communication, has realized the communication mode of wireless broadband internet.

Description of drawings

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1 is existing set-top box block diagram;

Fig. 2 is a block diagram of the present utility model;

Fig. 3 is the user mode figure of existing set-top box;

Fig. 4 is set-top box user mode figure of the present utility model.

Embodiment

As Fig. 2, shown in Figure 4: this set-top box comprises the system control module of being made up of central processing unit, system's read-only memory (ROM), Installed System Memory (RAM), erasable internal memory (FLASH); The Peripheral Interface module of forming by central processing unit, Remote Control Interface, serial line interface, parallel interface; And the radio network interface, audio frequency control module, video control module, figure control module, overlay controller and the television set that are connected by bus constitute jointly.

The collaborative work in the adjustment of network inserts of each module of set-top box, the wireless modulation-demodulation module is operated under the wireless communication state top box of digital machine.Because wireless network adopts analogue transmission signal, radio modem is the part of wireless set-top box system core, adopts 802,11 wireless transmission protocols technically.When set-top box sends request command, in a process of exchange that uses ICP/IP protocol, this order is converted into wireless transmission protocol to the wireless modulation-demodulation module and wireless access gateway is linked up, through the explanation of radio network gateway, on the common frame of the final arrival of this order Intemet service supplier.By the dynamic assignment method, make this user obtain the IP address of using in this transaction, and Internet is sent in request then.After the content of Internetd is found, then deliver to Internet service supplier (ISP) there, be responsible for it is delivered to user's set-top box again by the router of ISP.Set-top box is finished the task of a gateway between television set and network.Its task is the communication flows of managing I P, has the ability that the control user passes in and out network, in case the IP bag arrives set-top box, vision signal is separated from this bag, and data are wherein deciphered, and it is delivered on the television set to show then.

Claims

A kind of wireless digital set-top box, constitute by television set, system control module, Peripheral Interface module, audio frequency control module, video control module, figure control module, overlay controller and network interface etc., wherein said system control module, Peripheral Interface module are connected by the coaxial cable formation with audio frequency, video and the figure control module of user side, it is characterized in that: be provided with radio modem (A) at the network interface end and constitute radio network interface.
