According to the integration of three networks DTV STB of the invention described above, can also realize the terminal access internet function.
During realization; The network terminal (for example network insertion terminals such as PC, mobile phone, Ethernet embedded system) sends relevant wireless data packet; After radio interface unit receives, be transmitted to the EOC unit after being converted into the internet data bag, the EOC unit receives the internet data bag that radio interface unit is sent; After being converted into the HFC signal; Be transferred to the front end of hfc plant through tuner, but because hfc plant access band Ethernet itself, thereby can realize WiMAX function in view of the above by DTV STB.The network information (HFC signal) that feeds back to through the HFC net; After tuner receives; Be transmitted to the EOC unit; Send to radio interface unit after being converted into the Ethernet data bag by the EOC unit, radio interface unit feeds back to the terminal after converting the Ethernet data bag that receives into corresponding wireless data packet.If need on DTV, show, the Ethernet data bag through after the EOC cell translation can also send to the DTV unit, and demonstration can directly be exported to the Ethernet data bag in the DTV unit.
Integration of three networks DTV STB of the present invention, owing to be to net access network based on ethernet through the EOC unit by HFC, the access bandwidth of EOC unit is 100M; And the terminal is to carry out alternately with this integration of three networks DTV STB through wireless mode; In wireless coverage, need not to be laid with spider lines and promptly can insert the Internet, realized the function of broadband access in view of the above; And the access bandwidth of 100M can be provided in view of the above, and convenience is convenient, cost is low and bandwidth is big.
According to integration of three networks DTV STB of the present invention, can also realize a multicast function, put sowing time; User side sends the program request instruction through the terminal to DTV STB; This program request instruction is sent with the mode of wireless data packet, after radio interface unit receives, is to send to the DTV unit behind the Ethernet data bag with the program request instruction transformation that receives; The DTV unit receives the back and gets into the program request function, and (for example video information etc.) plays to obtain relevant programme information from the terminal.
If the DTV unit can't obtain corresponding programme information from the terminal; Then the DTV unit sends the Ethernet data bag that obtains program to the EOC unit; After the EOC unit receives this Ethernet data bag, send to HFC net (front end) through tuner after converting this Ethernet data bag into the HFC signal.After tuner receives the HFC signal that front end returns; According to the channel that receives this HFC signal; This HFC signal is exported to the DTV unit play, or, this HFC signal is transferred to the EOC unit; The EOC unit is to export to the DTV unit behind the Ethernet data bag to play output with this HFC conversion of signals, realizes the playing function of DTV in view of the above.
According to the DTV STB of the invention described above, because high bandwidth is provided, therefore; This DTV STB be can use simultaneously and the available various functions of Ethernet, for example VOIP (Voice overInternet Protocol, the networking telephone) function or the like realized; And provide the wireless access function of VOIP; Thereby through a DTV STB service function of digital TV network, the Internet, three networks of voice network can be provided, realize that three net physics merge.
When functions such as above-mentioned realization the Internet access, program request, DTV broadcast; The HFC signal of passing back for front end; Tuner transfers high-frequency signal to intermediate-freuqncy signal and exports to the DTV unit, improves the receptivity of DTV unit, reduces the components and parts cost.
For the HFC signal of EOC unit to the tuner transmission, tuner also transfers this HFC signal to high-frequency signal by intermediate-freuqncy signal, redispatches to the HFC net, to improve the anti-interference of signal in the transmission of HFC net.
Wherein, above-mentioned EOC unit can be any one in CABLE MODEM (cable modem), MOCAEOC terminal or the HOMEPLUS EOC terminal etc.Above-mentioned radio interface unit can be WiFi (Wireless Fidelity; 802.11b standard) interface unit, WAPI (Wireless LANAuthentication and Privacy Infrastructure; WLAN authentication and privacy infrastructure) any one in interface unit, the bluetooth interface units etc. is as long as can provide wireless access function.Radio interface unit can also be supported multiple in these wireless access ways for example to comprise WiFi interface unit, WAPI interface unit, bluetooth interface units simultaneously simultaneously, to support multiple wireless access way simultaneously, satisfies the needs that expand.
According to the integration of three networks DTV STB of the invention described above, the present invention also provides a kind of implementation method of integration of three networks DTV STB, and concrete performing step can not repeat them here as stated.
