Abstract
The invention discloses a testing method for scrambling program playing of a high-security set top box, which comprises the following concrete implementation processes: firstly, extracting program information from client software of a Nagra set top box; the Mtest software adopts a partition structure the same as that of client software, the extracted program information is written in the Mtest software, and then an upgrading step of upgrading a client is performed; after the upgrade is finished, the set-top box contains program information required by the test, and then the play test is directly carried out. Compared with the prior art, the testing method for the scrambled program playing of the high-security set top box has the advantages that the program information is written before the Mtest software upgrades the client software, so that the program information to be tested is stored after the client software is started, and the scrambled program can be tested after the client software is started, so that the testing time of the item of a single set top box is reduced to be less than 20 seconds, and the testing method is strong in practicability, wide in application range and easy to popularize.
Description
Technical field
The present invention relates to set-top box technique field, the method for testing of specifically a kind of practical, high peace Set Top Box scrambled program broadcasting.
Background technology
Digital video switching box (English: SetTopBox, be called for short STB), box on so-called Set Top Box or machine is the equipment connecting television set and outside source.The digital signal of compression can be changed into television content by it, and shows on a television set.
NagraMediaAccess is the core of Nagra Digital Television solution, provides the advanced security resist technology of terminal chip level.Adopt the production process overall flow of the Set Top Box of Nagra solution as shown in Figure 1.
Need two softwares in process of production, software 1 produces surveys software, i.e. Mtest software, is the software tested the hardware of Set Top Box, such as to USB interface, and network interface, front panels etc. are tested, and determine hardware fault-free; Software 2 client software, here referred to as APP software, is final shipment software, the software that user uses.
Before vanning, according to standard and the requirement of nagra, add a test request, the program needing Set Top Box to carry out scrambling is play.The scrambled program of Nagra has 4 covers altogether, and provide in the mode of TS stream, need factory's code stream player to broadcast, Set Top Box tuner receives, and just complete machine is qualified at last can to play this scrambled program.
The high peace type Set Top Box of Nagra type, production procedure is very complicated.Wherein there is a demand to be before dispatching from the factory, carry out the broadcasting test of scrambled program, be used for verifying that whether the mandate of this Set Top Box is successful.But in actual production, the testing efficiency of this project is too low.
Due to the software search mechanism of Set Top Box, all will carry out the broadcasting test of scrambled program for every platform Set Top Box, the time of cost is very many.The reason of time loss is caused to be: the software that dispatches from the factory of Set Top Box must be client software, it is adopt remote controller operation that client carries out tuning, by the feedback of TV, select the fixing frequency that will carry out tuning, Set Top Box has scanned this frequency, whether obtain the rendition list, then carrying out monitoring can this scrambled program of normal play.
As shown in Figure 2, operate with remote controller because needs produce lineman people, and need Set Top Box to be fixed the search of frequency, then the broadcasting of scrambled program can just be carried out, so whole test needs cost about 50 seconds, even if operative is very skilled, also need the time close to 40 seconds, and the speed that factory produces linear flow waterline is generally 20 seconds/platform, the output of 180pcs/ hour so just can be reached.
So the time loss of this test event must reduce to less than 20 seconds, just can satisfy the demands, otherwise the production efficiency of producing line will be had a strong impact on.
Based on this, now provide the method for testing that a kind of high peace Set Top Box scrambled program is play.
Summary of the invention
Technical assignment of the present invention is for above weak point, provides the method for testing that a kind of practical, high peace Set Top Box scrambled program is play.
The method of testing that high peace Set Top Box scrambled program is play, its specific implementation process is:
First, in the client software of Nagra Set Top Box, programme information is extracted;
Mtest testing software adopts the partitioned organization identical with client software, writes the programme information of said extracted, do the upgrade step of upgrade client afterwards in Mtest software;
After having upgraded, Set Top Box comprises the programme information needed for test, then directly does and plays test.
The leaching process of described programme information is: carry out normal tuning with client software, the scrambled program information needed for search; From the storage system of Set Top Box, obtain the data block of programme information, complete the extraction of programme information.
The detailed process of programme information write Mtest testing software is:
After Set Top Box is produced, in Mtest testing software, write the program information data block of said extracted;
Then updating client software;
After having upgraded, then Nagra Set Top Box restarted, this Nagra Set Top Box kind comprises programme information, and play-overing the program added in flow-disturbing can test.
The data structure of described program information data block comprises frequency point information, tsid, serviceid of TV programme and audio frequency and video pid.
The method of testing that a kind of high peace Set Top Box scrambled program of the present invention is play, has the following advantages:
The network single-chip microcomputer firmware upgrade method of one of this invention adopts and write programme information before Mtest software upgrading client software, after making client software start, just preserve programme information to be tested, the test of scrambled program just can be carried out after start, this project testing time of single set top box is made to be reduced to less than 20 seconds, practical, applied widely, be easy to promote.

Accompanying drawing 1 is the production process overall flow figure of the Set Top Box adopting Nagra solution.
Accompanying drawing 2 is the test schematic diagram that existing scrambled program is play.
Accompanying drawing 3 is programme information leaching process schematic diagram of the present invention.
Accompanying drawing 4 is programme information of the present invention write Mtest software process schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
The method of testing providing a kind of high peace Set Top Box scrambled program to play of the present invention, as shown in accompanying drawing 2, Fig. 3, its implementation procedure is:
First, in the client software of Nagra Set Top Box, programme information is extracted;
Mtest testing software adopts the partitioned organization identical with client software, writes the programme information of said extracted, do the upgrade step of upgrade client afterwards in Mtest software;
After having upgraded, Set Top Box comprises the programme information needed for test, then directly does and plays test.
The leaching process of described programme information is: carry out normal tuning with client software, the scrambled program information needed for search; From the storage system of Set Top Box, obtain the data block of programme information, complete the extraction of programme information.
