Embodiment Construction

[0019] The following is a preferred example

[0020] (1) Networking

[0021] Such as figure 1 Shown is a network diagram of a device that realizes the integration of TV and network transmission:

[0022] 108 is the Ethernet cable output by the user module, 101 is the user module, 102 is the cable TV distributor, 103 is the coaxial cable, 104 is the concentrator in the corridor, 105 is the filter between the corridor cable TV, and 106 is the concentrator output Ethernet cable, 107 is a cable TV coaxial cable.

[0023] The 104 concentrator modulates the Ethernet signal into a wireless signal through the 103 coaxial cable, 102 distributor, and transmits it to each user module 101. After the user module is decoded, the Ethernet signal 108 is transmitted to the user Ethernet;

[0024] On the contrary, the 108 Ethernet signal of the user module is modulated into a broadband analog signal by the 101 user module, then amplified, and transmitted to the concentrator through the 102 distrib...

Abstract

A television and network transmission integration device modulates 802.11a/802.11b/802.11g signal to )-65MH signal which can be adaptive transmitted in coaxial cable through impedance conversion, signal amplifying and filtering. Said invention can be used in cable TV network data transmission, wireless network domestic covering, digital TV STB and interactive television.

Description

1. Technical Field [0001] The present invention "a device for realizing the integration of television and network transmission" relates to a device for transmitting wireless network signals using a coaxial cable. 2. Background technology [0002] Nowadays, wireless network equipment has been widely used, but the wireless network uses 2.4GHz or 5.8GHz frequency, 2.4GHz and 5.8GHz frequency signal is not suitable for transmission in coaxial cable, the attenuation is large, and it cannot be passed through the splitter. [0003] The invention uses the 0-65MHz idle frequency of the cable TV to transmit the wireless network data signals of 802.11a, 802.11b, and 802.11g. [0004] Advantages of the present invention: [0005] (1) Can directly use wireless network protocols, including data packet sharing conflict handling, network security handling, etc. [0006] (2) Radio frequency signals with frequencies up to 2.4GHz and 5.8MHz are not suitable for transmission in coaxial cables, and a...
