Embodiment Construction

[0012] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0013] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0014] The radio frequency signal RF sent by the radio and television front end through the coaxial cable enters the sub-board of the set-top box and is filtered by a high-pass filter HPF201. Then the signal enters the splitter 203, and the signal is divided into two identical paths: one path enters the tuner 112 on the main board, after demodulation by the tuner 112, the high-frequency signal is restored to an intermediate frequency digital ...

Abstract

The invention discloses a set top box surfing the net through a coaxial cable and supporting a wireless network, comprising an intelligent card circuit, an SDRAM (Synchronous Dynamic Random Access Memory), an FLASHROM (Flash Read Only Memory), an EEPROM (Electrically Erasable Programmable Read-Only Memory), a USB2.0 interface, a net gape, a PHY (Physical Layer), a reset circuit, a front control plate, a high-frequency head, an audio processing module, a video processing module, an HPF (High Pass Filter), an LPF (Low-Pass Filter), a spliter, a CMTuner (Centimeter Tuner), the FLASHROM (Flash Read Only Memory), the EEPROM (Electrically Erasable Programmable Read-Only Memory), the SDRAM (Synchronous Dynamic Random Access Memory), a wireless module and an antenna. Network transmission is carried out through the coaxial cable and one signal wire is shared with a television signal, thereby conveniently and easily meeting the requirements of users on television watching and net surfing, preventing a modem from being independently installed and reducing the cost; and in addition, the set top box supports the wireless routing and is convenient for the use of the internet equipment of other terminals of the users so that the users are not necessary to connect excess net wires, thereby eliminating the limitation of space.

Description

technical field [0001] The invention belongs to the field of electronic equipment, and specifically refers to a set-top box which surfs the Internet through a coaxial cable and supports wireless routing. Background technique [0002] In the field of radio and television market, due to the rapid popularization of digital TV set-top boxes. With the development of triple play and NGB, it is a new trend to develop users into broadband users and provide users with multi-service services while developing digital TV users through set-top boxes. [0003] In today's homes, the set-top box and Internet access are basically separated, and xDSL is generally used for Internet access. In addition to paying monthly bills to different operators, there is also the trouble of too much wiring at home. If several terminals need to access the Internet, a router needs to be purchased. [0004] The present invention is a novel intelligent terminal which combines the function of the digital set-...
