Description
Technical field
The present invention relates to technical field of television sets, and in particular to a kind of side by CEC communication detection equipment active states
Method.
Background technology
Current intelligent operating system overall application on TV platform, by intelligent television platform, TV with other outside
The interaction of peripheral equipment is more and more, become increasingly complex, such as multi-screen interactive, Set Top Box countercharge.
The realization of these interactions, is substantially realized using wireless (such as WiFi) at present, therefore, for wanting for environment
Ask just very high.As network environment is unstable, the problems such as poor anti jamming capability occur, frequently go offline, between TV and ancillary equipment
Interaction cannot just realize.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided a kind of method by CEC communication detection equipment active states,
To expect in the case where cost is not increased, effectively solve dependence of the wireless interaction to network environment between TV and ancillary equipment and ask
Topic.
In view of the above mentioned problem of prior art, according to one side disclosed by the invention, the present invention uses following technology
Scheme：
A kind of method by CEC communication detection equipment active states, it includes：
Step one, set up the unified protocol instructions of a set of television and ancillary equipment end；
Step 2, television and ancillary equipment end are carried out into CEC networkings；
Step 3, television send status inquiry command, obtain the working condition of ancillary equipment；
When step 4, ancillary equipment working condition change, working condition actively is pushed to television, television is timely
Receive and process the change of state.
In order to the present invention is better achieved, further technical scheme is：
An embodiment of the invention, also including step 5, ancillary equipment crashes and judges：
Television timing sends CEC status inquiry commands, if continuing to exceed setting command number of times without obtaining periphery
The CEC responses of equipment, then it is assumed that ancillary equipment crashes, and television does corresponding abnormality processing.
Another embodiment of the invention, in the step 2：When the access of HDMI equipment has been detected,
Television peripheral device end sends querying command, asks OSD Name, ancillary equipment to reply OSD Name, if title is electricity
Depending on holding the ancillary equipment end title to taking over, television that the order for confirming networking is just sent to ancillary equipment end, television is again
After receiving ancillary equipment end confirmation, networking is completed.
The present invention can also be：
Another embodiment of the invention, in the step 3：Television sets up a thread, is completed in networking
Afterwards, television thread timing sends status inquiry command, obtains the working condition of ancillary equipment.
Compared with prior art, one of beneficial effects of the present invention are：
A kind of method by CEC communication detection equipment active states of the invention, using CEC communication mechanisms, sets up one
The order system that set TV and CEC ancillary equipment can be recognized, is communicated, in real time by CEC in ancillary equipment and TV Room
Grasp the working condition of ancillary equipment, it is ensured that the stability for interacting between TV and CEC ancillary equipment.
Brief description of the drawings
For clearer explanation present specification embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for the description of prior art is briefly described, it should be apparent that, drawings in the following description are only
It is the reference to some embodiments in present specification, for those skilled in the art, is not paying creative work
In the case of, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 shows overall architecture block diagram according to an embodiment of the invention.
Fig. 2 shows schematic flow sheet according to an embodiment of the invention.
Specific embodiment
The present invention is described in further detail with reference to embodiment, but embodiments of the present invention not limited to this.
As shown in Figure 1 and Figure 2, by the method for CEC communication detection equipment active states in intelligence system：It is logical using CEC
News mechanism, sets up the order system that a set of TV and CEC ancillary equipment can be recognized, by CEC in ancillary equipment and TV Room
Communicated, the working condition of ancillary equipment is grasped in real time.
The present invention utilizes CEC communication mechanisms, television set real-time query, the working condition of grasp ancillary equipment, it is ensured that TV
The stability for interacting between CEC ancillary equipment.
Television utilizes HDMI CEC communication functions, sends certain protocol command, and real-time monitoring understands the work of CEC equipment
Make state, solution TV interacts the Dependence Problem to network environment with wireless (WiFi) between ancillary equipment.
The television reception machine series products of HDMI CEC communication functions can be supported.Television set is cooperateed with out with CEC equipment
Hair, is not not required to the equipment taken over.It may include following steps：
A, when monitoring to have on TV CEC equipment to access, behavior of shaking hands (CEC networkings)；
B, after shaking hands successfully, can timing be communicated with CEC equipment, carry out state renewal (heartbeat mechanism)；
C, the working condition of real-time reception CEC equipment update and process.
And ancillary equipment deadlock judgement can be carried out using CEC communications.
Specific handling process is as follows：
1. a set of protocol instructions are set up, and television and ancillary equipment end are all designed and process according to agreement.
2.CEC networkings：When HDMI equipment access (hotplug is height) has been detected, send inquiry to equipment and order
Order, asks OSD Name, ancillary equipment to reply OSD Name, if title is television system to the peripheral name taken over,
The order for confirming networking is just sent to ancillary equipment, after being received again by ancillary equipment confirmation, networking is completed.
3. status inquiry：Television sets up a thread (hander), and after the completion of networking, the timing of television thread sends
Status inquiry command, obtain ancillary equipment working condition, such as start whether completes, Recovery success or not, WiFi connect
Or disconnect etc. state.
4. ancillary equipment is pushed：Receive the working condition changing push of ancillary equipment, ancillary equipment working condition becomes
During change, working condition actively is pushed to television, television receives and processes the change of state in time.
5. ancillary equipment crashes and judges：Television timing sends CEC status inquiry commands, if continuous 5 subcommand does not have
Obtain the CEC responses of ancillary equipment, then it is assumed that ancillary equipment crashes, and television does corresponding abnormality processing.
In sum, the present invention, by the agreement set up, is detected by TV and is grasped periphery using HDMI CEC communications
The state of equipment, makes feedback processing in time, compensate for the defect of wireless interaction between TV and ancillary equipment.
