Eoc Module Use in Set Top Box (STB103/STB203)

Product Overview

STB103 is an EOC module card (Slave) built in the Set Top Box, using Qulcomm Atheros 6400 solution, which can be networking EOC Master. They can build Layer-2 Ethernet transmit network through cable television coaxial cable and meanwhile have no influence on the pre-existing CATV signal transmit.

STB103 provides three 100M full-duplex Ethernet interfaces. One is inside the Set Top Box, connecting with STB main board, used for back transmission of digital television interactive signal. The other two Ethernet interfaces locate on the panel of STB, used to connect with different terminals such as computer and IP phone.

STB103 supports QoS set up and can provide corresponding transmit guarantee of priority level for data stream of different service types. It supports bandwidth control. Maximum Uplink bandwidth can be set up in order to prevent the attack to the whole coaxial transmit network when devices of other customer premises network go wrong or artificial attack happens. Encrypted transmit is also available to satisfy the service need of high reliability.

STB103 and CLT101 networking completely meets the requirement of Triple-play (integrating three networks into one) of broadcasting and television system. In actual networking, one single CLT101 can under-connects 253 STB103 to realize relatively high convergence ratio. STB103 occupies Low Frequency Band under 30MHz and has no collision with the current CATV system frequency which can decrease mutual interference.

STB203 is used Qulcomm Atheros 7411 set-top box solution module, low occupancy below the 65MHz band, the same as other features and STB103.
