Background technology
At present, TV Dongle adapters in the market generally all realize power supply, and pass through by independent power supply adaptor
It is not need to that WIFI module, which connect the advantages of realizing data transmission, video data transmission is carried out using WIFI module with home gateway,
Additional wiring, but cost is higher, and occupies massive band width, and signal quality is easily affected by environment, leads to the video of transmission
Jitter.
In addition, increasing with broadcasting and TV business, the business such as video on demand, high definition television, broadband access network are in rapid growth
Situation, if any business all WIFI modules through home gateway are transferred to each terminal, the load of WIFI module certainly will increase, can
Can be in the presence of being unable to stand, so as to influence the business experience of terminal.
And as smart home device is also more and more, such as set by central controller and each electricity consumption in family
It is standby to be attached, instruction realization is sent to the control of each electrical equipment by central controller or utilizes existing family
Gateway realizes the connection with each electrical equipment, and electrical equipment is sent a command to by home gateway.Under existing framework, family
Front yard gateway carries out data interaction by wireless communication mode and electrical equipment, some require to set than relatively low electricity consumption to data volume
It is standby, it can meet the requirements substantially through the above way.But when home gateway is toward smart television real-time transmission of video information, video
The data volume of information is bigger, often occupies bigger bandwidth, causes home gateway cannot be effectively toward other electrical equipments
Data interaction is carried out, the situation of remote control failure is caused to occur, operates understable property.In addition, home gateway and smart television
Between wirelessly transmit signal, influenced by indoor environment, home gateway be also difficult to toward smart television transmit high quality
Vision signal, the vision signal of high quality is often in wireless transmissions by the larger interference of indoor environment.
