Description
Technical field
What the present invention relates to is a kind of set top box testing technology, particularly be a kind of network television-set top-set-box automatic testing equipment and method.
Background technology
The IP set-top box is exactly and television set constitutes a kind of terminal equipment of IPTV (internet television) network jointly, its effect is that the media conversion from IP network that will receive is the signal that television set can receive, and simultaneously the operation of user's remote controller is converted to the request message business of sending to equipment is provided.The difference of IP set-top box and top box of digital machine is: the IP set-top box processes is from TCP/IP grouping of network message, and top box of digital machine is handled the digital signal from coaxial cable.Just because of this change, the software of equipment room, hardware interface become simply, all use the Ethernet interface access network, thereby become a kind of novel consumer electronics product that audio/video program is provided;
It generally has multiple audio-video signal output port, requires in the production testing process quality of output signals of its each port is tested.Simultaneously, the realization of network TV business need make up by media server, EPG navigation server, the system platform that multiple servers such as operation management clothes device are formed, and provide TV programme to set-top box users, and carry out operation management by this complicated system platform.
Existing IP set-top box test method: the IP set-top box has not only possessed the function of traditional simulated television business, and many value-added services also are provided, and the scope of business comprises:
1, traditional television channel business; 2, interactive TV channels business; 3, VOD service; 4, telecommunication service (comprising voice communication, video communication, video conference etc.); 5, Internet service (comprising web page browsing, online game, download, instant messaging etc.).But because the shortage of measuring technology, usually adopt real applied environment of simulation, the remote controller simulation actual user's hand-manipulated by the people operation, set-top box audio-video signal to deliver to television set, the mode of the signal output effect of manual detection equipment is finished the test of IP set-top box.
Digital TV set-top box manual testing method efficient is very low like this, and if the production of network television-set top-set-box still prolong method with the manual testing, will be one very loaded down with trivial details, drop into and occur more greatly and easily failing to judge and judging wrong engineering by accident.Wherein reason mainly contain following some:
At first, the output of set-top box is bigger usually, in production link, if it is bigger to build regular IPTV service system platform input ratio.In addition, traditional manual testing also will be equipped with the Authentication devices of considerable TV as output signal;
Secondly, set-top box will manually be carried out a series of configurations to set-top box, as join MAC after being inserted, IP, and server networking address, user name, password or the like could obtain programme signal from the service system platform.The Function detection of set-top box also needs a manual remote control device button operation that is simultaneously, and whole process is more loaded down with trivial details.
At last, the manual testing is received the output of the audio frequency and video of set-top box on the television set by the tester, carries out quality of production test by what platform equipment range estimation ear was listened, occur easily failing to judge and erroneous judgement and operating efficiency low.Though the dedicated tone video test instrument is the determining interface quality accurately, but still can not solve Efficacy Problem when producing in enormous quantities, and somewhat expensive.
In view of above-mentioned defective, creator of the present invention has obtained this creation finally through long term studies and practice.

The step of stating is just with procedure and step refinement, and its whole test process receives the set-top box that detects installing in fact, and please in conjunction with shown in Figure 2, it mainly comprises two processes:
First process is set-top box 1 an input signal process.The set-top box 1 that need detect is after startup, by the test program downloading service module 21 of the first interface a from described programme signal generating unit 2, download the special test application program, this downloads obtaining the test program source in the simplest and the most direct mode from described programme signal generating unit 2, avoids with the just examination release process in the set-top box 1.After described set-top box 1 is downloaded and finished, will start automatically and download, this program guides described set-top box 1 to carry out WEB to WEB service navigation module 22 and connects, and obtain program navigating information by the second interface b.
Described set-top box 1 is finished the access daily record, record is sent to the set-top box state processing module 41 of control unit 4 by the 3rd interface c.Described control unit 4 is followed according to set-top box 1 current state and preset operation plan, judge the instruction that remote controller (remote signal generating unit 6) is operated by operational order generation module 42, and operational order is issued the operational order receiver module 61 of remote signal generating unit 6 by the 4th interface d.
Described operational order receiver module 61 is to the operation of remote controller triggering command with instruction transformation, transfers to infrared signal generation circuit module 62 and sends out.The infrared remote-controlled signal that described infrared signal generation circuit module 62 sends is received by described set-top box 1 by the 5th interface e, and it is produced the operation of commands for controlling, realizes the simulation to remote controller.
Second process is the process that the set-top box output signal is carried out corresponding test.Described set-top box 1 is exported corresponding audio-video signal according to the requirement of remote signal, this signal is exported to the N:1 of audio and video matrix circuit unit 3 audio and video matrix circuit module 31 by the 6th interface f, described control unit 4 is followed according to the preset operation plan, chooses a road in set-top box 1 signal of N road by the 7th interface g control audio and video matrix routing control module 32 and exports.
The capturing and coding circuit submodule of described audio-video collection detecting unit 5 is returned signals collecting by the 7th interface h, and according to the numbering of corresponding set-top box 1 with signal to being stored as file.Described audio frequency and video output detection module 52 as a result will be analyzed the audio frequency and video output signal of each set-top box 1 according to the statistics in primary signal index and the database, determine whether the output of set-top box 1 audio-video interface accords with the total quality requirement.Described audio frequency and video output detection module 52 as a result also will be by the 9th interface i, and collaborative described set-top box state processing module 41 is carried out set-top box 1 state analysis, and the assistance tester makes set-top box 1 final judgement whether working properly.The statistics filing of various quality testings also can manually be inspected and carry out to Cun Chu signal for the testing staff by random samples simultaneously.
It can significantly improve the efficient of detection for the present invention, supposes each set-top box 1 at every turn by after the circulation in turn, and the output signal time is m minute, and every set-top box 1 to require the operating time of machine test output be n minute because m is much smaller than n.Then under the normal condition at n+N*m after the time, test job personnel can finish the collection for the audio-video signal quality test work of N platform set-top box 1, needed test job time quantum relatively with the N*n time, utilize this time-multiplexed thought, also reached the high efficiency purpose of little input.
The above only is preferred embodiment of the present invention, only is illustrative for the purpose of the present invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes to it in the spirit and scope that claim of the present invention limited, revise, even equivalence, but all will fall within the scope of protection of the present invention.
