Grade, but the replacement cycle of TV is considerably beyond smart phone.Current each producer is to cater to user to swim with HD video, TV
The demand of the different performances such as play, shopping, K song, the external connection module all docked in release with smart television pass through the function of TV
Module realizes new iteration upgrading.
Equipment network refers in two equipment rooms through a set of communication protocol, so that two equipment is established network communication, by two
Kind smart machine content mergence together, makes equipment content can be carried out unified operation；In view of the practical biography of current wireless network
Defeated rate, after smart machine networking, data transmission usually utilizes the CEC transport protocol of HDMI standard: in the wifi of transmission complete machine
While information and the module corresponding network information, related data is transmitted by the data line of HDMI, this transmission process when
Between also can with application data packet size have difference.
When user's practical operation, the waiting time is longer other than TV and module carry out transmission data, module reliably networks,
Complete machine obtains module application information etc. and is also required to the time.If period is related to network type switching, the mutual of wireless device does
It disturbs, the factors such as router performance is poor, can also directly result in and directly be unable to networking between TV and module or networking is slack-off, use
Family is in complete machine end operation module in application, can obviously feel that key response postpones.The unreliability of this system operatio, will lead to
User experience is deteriorated.
Current technology scheme is to carry out wifi connection between two equipment after two smart machines start networking.Cause
Wifi system itself transmit data unstability and transmission rate it is too big by such environmental effects, elapsed time is too long.It is practical
When transmitting data, transmission channel is easy to the interference by external environment and TV external equipment, the individual body of TV operation module
It is too big to test sense difference, it is uncontrolled.
Summary of the invention
The technical problems to be solved by the present invention are: proposing a kind of smart television and intermodule rapid networking method, solve
Networking mode bring networking rate is low in traditional technology, and the time is long, vulnerable to interference the problem of.
The technical solution adopted by the present invention to solve the technical problems is: smart television and intermodule rapid networking method,
Include:
Network channel is constructed by remote network driver interface specification using USB in smart television and intermodule, multiplexing is existing
Some network communication models and protocol tool, so that the wifi network channel under the network channel and DCC model that pass through USB building
Two-way simultaneous realizes compatibility.
The network-building method specifically includes:
1), smart television initializes module by USB interface: first check from MDD be transmitted through come module's address；
2), smart television configures module by USB: initialization is applied in the space including global data variable, in
The mounting of disconnected function, the mounting of other function pointers；
3) data transmission and control channel, are established: after configuration data, creating 4 pipelines between smart television and module
Data and transmission of control signals are transmitted, is specifically included:
31), EP0 is used for the control of usb protocol itself,
32), upstream transmission passage of the EP1 as Host-Device,
33), EP2 does the downlink transfer channel of Device-Host, for upstream and downstream here is all counter mould
34), FIFO overflow value is specifically equal to the size of interrupt structure body, in this way for generating interruption by EP3
As soon as obtaining an interruption data every time just generates an interruption at once, combining has had one to have full duplex access and control
The full link of access processed is for simulating network interface card.
4, hardware and software environment is resetted:
1) it opens EP0 and receives and respond reset and configuration, complete the hardware initialization of USB；
2) movement once disconnected is completed, after waiting 3ms confirmation system connection that can work, simulation is disconnected and connects
It connects
5, interrupt driving: data exchange is entirely to be driven by interrupting；One interruption is performed, and removes the interruption simultaneously
Continue the next interruption of circular test, interruption service is just exited in all interruptions after all being responded.Highest priority
In the top, the minimum most end in program.When allowing to occur multiple interruptions, according to the control of smart television with the height of priority
Low sequence executes.
6, module transmits and receives management information and uses communication class interface EP0, and module transmits and receives data information and uses interface
EP2、EP1。
The beneficial effects of the present invention are:
The transmission of data between smart machine is carried out using USB mode, directly using USB transmission data to save wifi
The networking Connection Time；The average speed of complete machine and module transfer data reliably guarantees user experience in 15M/S or more, improves and produces
The competitiveness of product.
Detailed description of the invention
Fig. 1 is networking hardware schematic between smart television and module in embodiment；
Fig. 2 is smart television and the transmission channel schematic diagram after intermodule networking in embodiment.
Specific embodiment
The present invention is directed to propose a kind of smart television and intermodule rapid networking method, solve networking mode in traditional technology
Bring networking rate is low, and the time is long, vulnerable to interference the problem of.
In the present invention, network is constructed by remote network driver interface specification using USB in smart television and intermodule and is led to
Road is multiplexed existing network communication models and protocol tool, so that under the network channel and DCC model by USB building
Wifi network channel two-way simultaneous realizes compatibility.
The solution of the present invention is further described with reference to the accompanying drawings and embodiments:
For being applied in Changhong 55Q2R complete machine by above-mentioned implementation, specific implementation method is as follows: logical using USB
Remote network driver interface specification is crossed, the network communication models of a standard are established in complete machine and module end, easily at two
Equipment room transmits data, and transplanting bottom USB driving varies without complete DCC traffic model now, it is logical to be multiplexed pervious network
Believe model and protocol tool, guarantees to realize by the communication channel of USB and the wifi network channel two-way simultaneous of former DCC simultaneous
Hold, finally simplifies the network communication models of two equipment rooms.
When implementing networking, using following means:
