The disclosure relates to the field of information processing, and more particularly, to a method and system for synchronously reproducing multimedia multi-information.
When a set of multi-media multi-information that concurrently involve in information such as sounds, images and words, whereabouts and behaviors is stored, played back, retrieved and queried, there is a need to use a plurality of software and hardware devices and systems as well as means and methods at present.
1. a Common multi-media multi-information set include:
(1) Information contained in authorization and testing processes of China's Ministry of Public Security on a motor vehicle driving license:
1.1 Real-time video information of not less than two channels;
1.2 Real-time audio information in a driving cab of a test car;

2. Existing methods for synchronously reproducing the multi-media multi-information:
When the set of the multi-media multi-information which concurrently involve in the information such as sounds, images and words, whereabouts and behaviors is stored, played back, retrieved and queried, the following numerous technologies are adopted for integration at present:
1. The sounds/images are synchronously collected and recorded by means of an audio/video collecting and recording system.
2. The non-sound/image information is recorded by means of a computer database system.
3. When the multi-media multi-information is traced, a corresponding sound/image player is played back or restored. The non-sound/image information is searched, queried and displayed by means of a database query system. The moment-to-moment position where a monitored object locates corresponding to that time is simulated by comprehensively employing the database query system and a virtual technology to display and restore.
After relevant regulations of China's Ministry of Public Security on authorization and testing processes of the motor vehicle driving license are modified from the previous decree No. 111 to the decree No. 123, a method for evaluating a driving skill testing process of a motor vehicle testee is changed to be done mainly by means of a computer from a manpower. Moreover, it is required that all information of the whole testing process can be traced at any time, that is, the testing process of any testee can be played back or restored completely at any time so as to review or correct an error accurately.
To record the complete information of one testee in the testing process, the following numerous technologies are adopted for integration in the related art:
1. The audio/video inside and outside the test car are collected and recorded by means of the audio/video collecting and recording system.
2. The information such as test car, testee, tester, testing time, test scores, judgment basis and real-time position of the test car in the driving process is recorded by means of the computer database system.
3. When the testing process of the testee is traced, the audio/video information is played back or restored using the corresponding audio/video player. The information such as test car, testee, tester, testing time, test scores, judgment basis and moment-to-moment information is searched, queried and displayed by means of the database query system. The moment-to-moment position where the test car locates is searched and queried using the database query system and is simulated using the virtual technology to display and restore.
3. Defects of the existing methods for synchronously reproducing the multi-media multi-information:
(1) When the process information is traced, a plurality of systems which cannot be associated concurrently and correspondingly on a matter of time is required to be used. As a result, the problem that the information such as sounds, images and pictures are synchronous to other various information such as non-sound, non-image and non-picture information cannot be solved in a playback no matter in theory or in practice. For example:
When the driving skill testing process of the driver is recorded, a plurality of information set documents is needed. When the video and the traveling track need to be reproduced, an asynchronous phenomenon is particularly prominent, and a time difference between the traveling track depicted asynchronously and a video signal recorded by the test vehicle in real time is uncertain and is not able to be controlled at all. As a result, it is very easy to cause a visual error, and when judging a score deduction point, an observer will consider that it is a judgment error and even has a suspicion or a dispute to the correctness.
When the physical examination is performed on the person who needs to learn the motor vehicle driving skill before the enrollment, to avoid the unhealthy tendency, prevent the falsification and guarantee the justice and equity, it is specified in a new standard that corresponding work should not be allowed to be done by a physical examination organization affiliated to the vehicle administration office under the real-time monitoring of polices of the vehicle administration office, but should be done by a neutral hospital not intervened by the vehicle administration office directly and having a physical examination qualification as a third party. At this moment, to guarantee the authenticity of a physical examination result and implement the effective process monitoring, there is a need to combine the audio/video information as evidences. Now, there occurs that the reproduced information has an obvious time asynchronous problem in monitoring inspection: the physical examination result represented by the words has not a fixed time relationship with the audio and the video in the physical examination process.
(2) When static information and dynamic information occurred at any moment are stored using a current database technology, for example, when the static information such as test car, testee, tester, testing time, test scores, judgment basis and moment-to-moment information as well as the dynamic information of the test car position are stored using the current database technology, due to the universality of an interface and the openness of the technology, the security cannot be guaranteed and the information is falsified by a lawbreaker very easily, thereby damaging the authenticity of information data.
(3) When the static information irrelevant to a time and the dynamic information in one-to-one corresponding relation with the time are stored using the current database technology, the information is respectively stored to multiple different types of documents. For example, as the test information of the same testee is respectively stored to the multiple different types of the documents, it is very troublesome, labor-consuming and time-consuming to find it. If the information needs to be synchronously reproduced, it becomes more difficult, and sometimes the time difference even exceeds 10 min.
The embodiments of the disclosure provide a method and system for synchronously reproducing multimedia multi-information, so as to solve the above problems in the related art.
According to one aspect of the embodiments of the disclosure, a method for synchronously reproducing multimedia multi-information is provided.

The method includes the following basic steps: A, a step of synchronously recording the multi-information: the step is to insert “non-audio/video information” into an “audio/video steam before compression” or an “audio/video steam after compression or a file thereof” by a “multi-information mixer” of the “multi-information modulation unit”, that is, to embed some “additional information blocks” carrying the “non-audio/video information” into necessary “video frames” or “audio frames” in the “audio/video steam before compression” or the “audio/video steam after compression or the file thereof”; and/or, to create or insert some “additional information frames” carrying the “non-audio/video information” between the necessary “video frames” and “audio frames”, thereby finally forming a new multimedia multi-information audio/video stream CMSAV or multimedia multi-information file CMSAVF, wherein the multimedia multi-information audio/video stream CMSAV and the multimedia multi-information file CMSAVF meet requirements of a certain compression standard; and B, a step of synchronously reproducing the multi-information: the step is to, after enabling the “multimedia multi-information file CMSAVF”, which carries the “non-audio/video information” and seemingly still is an audio and a video suitable which meets the requirements of the certain compression standard, to pass through a “multi-information file demodulator” using a “multi-information synchronous reproducing unit” that is a “multimedia multi-information demodulation unit”, respectively obtain three information sets, namely the “additional information blocks”, the “video frames” and the “audio frames”, and then send the “video frames” and the “audio frames” taken as basic units of “multimedia stream information” to an “audio/video decoder or player” to restore audio/video information and scenes before being recorded, and perform corresponding “demodulation” or called as “decoding” processing on the “additional information blocks” obtained by demodulation from the “multimedia multi-information file CMSAVF” again to restore the “non-audio/video information” embedded into the “multimedia multi-information file CMSAVF”.
According to another aspect of the embodiments of the disclosure, a method for synchronously reproducing multimedia multi-information is further provided. The method is to respectively convert multi-channel audio information of a driving test into single-channel audio information HAS and convert multi-channel video information of the driving test into single-channel video information CVS, wherein the multi-channel audio information and the multi-channel video information are collected concurrently; then store the single-channel audio information HAS, the single-channel video information CVS and all information relevant to the driving test, such as, testee information, test scores, tester information and test vehicle information as well as indispensable real-time non-audio/video test information and non-real-time test information specified in a national standard or other requirements, together to all audio/video monitoring information which carries a testing process of testees, and form, in a form of a compressed file, a “driver testing process multi-information audio/video file DEMSAV” which includes various information of a driving testing process; and then synchronously reproduce all information recorded in the “driver testing process multi-information audio/video file DEMSAV” of a multi-information driving test synchronous recording process using a dedicated player capable of synchronously reproducing and playing back the multi-information. The method mainly includes three steps: (1) a step of collecting: multi-channel audio and multi-channels video are respectively converted into single-channel audio HAS and video CVS; (2) a step of storing: information collected in the step of collecting is combined with the real-time non-audio/video test information and the non-real-time test information to form the “driver testing process multi-information audio/video file DEMSAV” which includes the various information of the driving testing process; and (3) a step of synchronously reproducing: the all information recorded in the “driver testing process multi-information audio/video file DEMSAV” of the multi-information driving test synchronous recording process is synchronously reproduced using the dedicated player capable of synchronously reproducing and playing back the multi-information.

All other embodiments obtained by those skilled in the art based on the embodiments in the disclosure without creative efforts are within the scope of the protection of the disclosure.

It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein.

According to the embodiments of the disclosure, the embodiment of a method for synchronously reproducing multimedia multi-information is provided. It is to be noted that the steps shown in the flowchart of the accompanying drawings may be executed such as in a computer system having a group of computer executable instructions. Furthermore, through a logic sequence is shown in the flowchart, in some cases, the steps shown or described may be executed in a sequence other than here.
The method is a method of combining a plurality of relevant files or a plurality of information streams using a “multi-information modulation unit”, wherein the plurality of relevant files have an associated information relationship, and the plurality of information streams have an associated information relationship, and then synchronously reproducing the relevant files or the information streams using a dedicated player capable of synchronously reproducing and playing back the multi-information. The method includes the following basic steps.
A, a step of synchronously recording the multi-information: the step is to insert “non-audio/video information” into an “audio/video steam before compression” or an “audio/video steam after compression or a file thereof” using a “multi-information mixer” of the “multi-information modulation unit”, that is, to embed some “additional information blocks” carrying the “non-audio/video information” into necessary “video frames” or “audio frames” in the “audio/video steam before compression” or the “audio/video steam after compression or the file thereof”, and/or, to create or insert some “additional information frames” carrying the “non-audio/video information” between the necessary “video frames” and “audio frames”, thereby finally forming a new audio/video stream CMSAV or file CMSAVF thereof that meets the requirements of a certain compression standard; and
B, a step of synchronously reproducing the multi-information: the step is to, after enabling the “multimedia multi-information file CMSAVF”, which carries the “non-audio/video information” and seemingly still is an audio and a video meeting the requirements of the certain compression standard, to pass through a “multi-information file demodulator” using a “multi-information synchronous reproducing unit” that is a “multimedia multi-information demodulation unit”, respectively obtain three information sets, namely the “additional information blocks”, the “video frames” and the “audio frames”, and then send the “video frames” and the “audio frames” taken as basic units of “multimedia stream information” to an “audio/video decoder or player” to restore audio/video information and scenes before being recorded, and perform corresponding “demodulation” or called as “decoding” processing on the “additional information blocks” obtained by demodulation from the “multimedia multi-information file CMSAVF” again to restore the “non-audio/video information” embedded into the “multimedia multi-information file CMSAVF”.
In the A, the step of synchronously recording the multi-information, first, the “audio/video information” is collected digitally, synchronously and respectively to obtain an information stream, which is not compressed, of an original digital audio/video mixed information stream AVS; and then, according to different synchronization time differences, either the following A1 or A2 is adopted or the following two methods are adopted simultaneously.
Basic method 1: a method highly demanding on the synchronization time difference (the synchronization time difference is required to be relatively small), i.e., the A1 method: first, the “non-audio/video information” is inserted into the synchronously collected digital “audio/video information AVS” using the “multi-information mixer” to form the information stream of the multi-information audio/video stream MAVS formed after the non-audio/video information is added to the AVS; and then, the information stream is sent to a “digital information compressor” for compression, thereby finally forming the audio/video information stream CMSAV or the file CMSAVF thereof stored in a “file recorder”, wherein the audio/video information stream CMSAV is able to meet the requirements of some audio/video compression standard, carries the non-audio/video information and appears in a compressed form.
The key point of the method is to insert the “additional information blocks” into an audio stream or a video stream which is just synchronously collected and is not compressed and then perform the compression processing to form the CMSAV stream. The specific steps (referring to
Basic method 2: a method undemanding on the synchronization time difference, i.e., A2 method: first, the synchronously collected digital “audio/video information” AVS is sent to the “digital information compressor” for compression to form the compressed information stream of the audio/video mixed information stream CAVS; and then, the “non-audio/video information” is inserted using the “multi-information mixer”, thereby finally forming the audio/video information stream CMSAV or the file CMSAVF thereof stored in the “file recorder”, wherein the audio/video information stream CMSAV is able to meet the requirements of some audio/video compression standard, carries the non-audio/video information and appears in a compressed form.
The flowchart of the method is as shown in
The method here has the advantages that an information source output by an existing external audio/video device that is able to output the compressed audio/video information, such as network camera, video server and the like on the present market, may be used as a carrier of the “additional information blocks”, such that the software and hardware resource overhead of the technical device of the disclosure is reduced. In other words, at this moment, the III11, III12, III2B and III2 modules in the
As a transformation of the embodiment of the disclosure, to insert the information undemanding on the synchronization time difference, besides the A2 method, the A1 method may be adopted simultaneously or individually.
In the A, the step of synchronously recording the multi-information, according to different processing methods adopted upon different positions of the “non-audio/video information” where are inserted into the “audio/video information stream”, there are the following several different implementation ways.
{circle around (1)} when there merely has the “video stream” in the “audio/video stream”, the “additional information block” formed by the “non-audio/video information” is inserted in a form of taking an “additional information frame S33x” as a carrier, wherein the “additional information frame S33x” is created between adjacent two frames of the video stream V33x and V33x1 (referring to
{circle around (2)} when there merely has the “audio stream” in the “audio/video stream”, the “additional information block” formed by the “non-audio/video information” is inserted in a form of taking an “additional information frame S34y” as a carrier, wherein the “additional information frame S34y” is created between adjacent two frames of the audio stream A34y and A34y1 (referring to
{circle around (3)} when there simultaneously includes the “video” and the “audio” in the “audio/video stream”, the “additional information block” formed by the “non-audio/video information” is inserted in a form of taking an “additional information frame” as a carrier, wherein the “additional information frame” is created between adjacent two frames of the video stream or created between adjacent two frames of the audio stream or created between the adjacent two frames of the video stream and simultaneously created between the adjacent two frames of the audio stream.
The above is the most convenient and direct method for synchronously reproducing the multimedia multi-information and is applied to storing single information in various occasions.
{circle around (1)} when there merely has the “video stream” in the “audio/video stream”, the “additional information block a” formed by the “non-audio/video information” is embedded into the “video stream” and into an xth video frame corresponding to a time when the “non-audio/video information” occurs; referring to
{circle around (2)} when there merely has the “audio stream” in the “audio/video stream”, the “additional information block b” formed by the “non-audio/video information” is embedded into the “audio stream” and into a yth audio frame corresponding to a time when the “non-audio/video information” occurs; referring to
{circle around (3)} when there simultaneously includes a “video stream” and an “audio stream” in the “audio/video stream”, the “additional information block a/b” formed by the “non-audio/video information” is inserted into the “video stream” and into some video frame corresponding to a time when the “non-audio/video information” occurs, or inserted into the “audio stream” and into some audio frame corresponding to a time when the “non-audio/video information” occur, or inserted into the “video stream” and into some video frame corresponding to a time when the “non-audio/video information” occurs and inserted into the “audio stream” and into some audio frame corresponding to a time when the “non-audio/video information” occur (referring to
{circle around (4)} according to the need, the “additional information blocks a1, a2/b1, b2” formed by the “non-audio/video information” may be individually inserted into a “video stream” formed by an “Xth video frame” into which the “additional information block a1” has been embedded and an “X+1th video frame” into which the “additional information block a2” has been embedded, in the form of taking an “additional information frame S37x” created between adjacent two frames of the video stream V37x and V37x1 as a carrier. Referring to
Alternatively, the “additional information blocks a1, a2/b1, b2” formed by the “non-audio/video information” are inserted into an “audio stream” formed by “yth audio frame” into which the “additional information block b1” has been embedded and an adjacent audio frame of a “y+1th audio frame” into which the “additional information block b2” has been embedded, in the form of taking an “additional information frame S38y” created between adjacent two frames of the audio stream V38yx and V38y1. The A38y and A38y1 are all audio information sets of some two frames in the “audio stream” which carries the “non-audio/video information” NAVS. The A38y is the “additional information frame” which is inserted between adjacent two audio frames, carries a “non-audio/video information block” and is independent of the video frames.
According to the need, the above two methods may be employed simultaneously, i.e., the “additional information blocks”, while being embedded into some video frame of a “video stream”, are inserted between adjacent two frames of the “video stream” in the form of taking an “additional information frame” as a carrier, wherein the “additional information frame” is created between the two adjacent frames of the video stream. Furthermore, the “non-audio/video information” is not only taken as the “additional information blocks” to be embedded into some audio frame of an “audio stream”, but also inserted between adjacent two frames of the “audio stream” in the form of taking an “additional information frame” created between the two adjacent frames of the audio frame as a carrier (referring to
The method in the embodiment is applicable to a place where important information is stored, for example, the (3) information to be related at various accident sites mentioned in the background:
3.1 Audio/video information in a site exploration process;
3.2 Site information generated by exploration survey;
3.3 Information of a site handling unit and personnel responsible for site handling at that time; and
3.4 Information of a site handling result.
(4) Various information required to be involved in various real-time monitoring:
4.1 Information such as audio, video, real time, traveling track and relevant scheduling and management generated in daily monitoring and real-time tracking processes of vehicles which carry out a special task such as cash truck and dangerous goods transport vehicle;
4.2 Relevant information needed to strictly control each corresponding stage of product monitoring and inspection processes using means such as sounds and images;
4.3 Various information to be managed in vehicle registration and 4S store service monitoring;
4.4 Relevant information required in a bank service monitoring process;
4.5 Sounds, images, pictures and correspondingly all other documents used as evidences; and
4.6 In measurement, analysis and teaching processes, there often exist some information transferred from audios generated by means of lighting or vibration and factors thereof generating these information, for example, an incandescent lamp will light when there is a certain current, and within a certain current range, the light intensity will be in direct proportion to the current which makes the lamp light.
As one transformation of the method for synchronously reproducing the multimedia multi-information in the first and second examples of the disclosure, when the “non-audio/video information” that needs to be added is associated with the real time when the “non-audio/video information” occurs, the processing method for synchronization of the additional information and the audio/video is as follows: the “additional information” which carries the “non-audio/video information” and the audio/video are created on corresponding positions having a constant time difference range on a same time axis, and in playback, are appropriately reproduced on the same time position (referring to
As another transformation of the method for synchronously reproducing the multimedia multi-information in the first and second examples of the disclosure, to make sure that all information loaded in the “audio/video information” is able to be secure and reliable, the “non-audio/video information” should be encrypted with a common encryption method before being loaded to the “audio/video information” in the A, the step of synchronously recording the multi-information, and furthermore, the “additional information block” should be further encrypted. That is to say, a changeable “block structure” is adopted, or a method of splitting same “additional information” into a plurality of “video frames” or “audio frames” or “additional information frames” is adopted for encryption.
As a still another transformation of the method for synchronously reproducing the multimedia multi-information in the first and second examples of the disclosure, the function to the “multi-information file demodulator” is limited to merely allow to “read a file”. However, the functions of “editing, falsifying and rewriting” the “additional information” obtained when reading the “file” are not provided. An operator in reproduction and playback is able to add the “additional information” secondarily to record the file as required; and if there is a special requirement, a corresponding “file permission” is further allowed to be set to improve the encryption degree.
When a “media stream” carrying the “non-audio/video information” is multi-channel audio and multi-channel video information, there is a need for the media stream to be able to meet the “synchronization” requirement. The synchronous processing method is to increase an A0: preprocessing step before the A, the step of synchronously reproducing the multi-information, so as to form single-channel audio/video information.
For a multi-channel video, before it is recorded, all video information are synthesized, using a “video digital mixer”, into single-channel video information CVS that is a single-channel digital video information stream CVS.
For a multi-channel audio, before it is recorded, all audio information are synthesized, using an “analog audio signal mixer II2”, into single-channel analog audio information HAS, and then are changed into single-channel digital audio information DAS that is a single-cannel digital audio information stream DAS with the digital audio information from a “digital audio pickup II3n” using a “digital audio mixer II4” after passing through an “audio digital collector II30”.
Thereafter, some “non-audio/video information” are embedded into the “audio/video stream” corresponding to the time when these information having an association relationship occur by employing the method in the first embodiment or the method in the second embodiment or by simultaneously adopting the methods in the first and second embodiments, and then are synchronously reproduced using a dedicated player capable of synchronously reproducing and playing back the multi-information.
The increased A0: the preprocessing step is as follows.
In A01, the multi-channel audio information is mixed into the single-channel video information CVS using a video processing unit of a data collection unit (referring to
The method is to simultaneously collect real-time dynamic video signals of h channels of analog video cameras for monitoring or k channels of digital video cameras for monitoring and perform digital processing, and at last combine into digital video signals CVS for later comprehensive processing or simple storing and recording, wherein the digital video signals CVS are able to meet, merely needing one channel, the requirements of a national standard and the special requirements of a user; the values of the above h and k are as follows: h=0, 1, 2 . . . 31, k=0, 1, 2 . . . 31, and h+k=1, 2, 3 . . . 32.
In A02, the multi-channel audio information is mixed into the single-channel audio information DAS using an audio processing unit of the data collection unit (referring to
The method is to simultaneously mix, by a circuit, m channels of real-time audio analog signals output by “analog audio pickups” for monitoring or n channels of real-time audio digital signals output by “digital audio pickups” for monitoring into single-channel audio signals DAS to output, wherein the single-channel audio signals DAS is able to meet, merely needing one channel, the requirements of the national standard and the special requirements of the user, and is taken as signal sources needed by an audio digital collector and an analog audio monitor; the values of the above m and n are as follows: m=0, 1, 2 . . . 31, n=0, 1, 2 . . . 31, and m+n=1, 2, 3 . . . 32.
The method here is most applicable for recording the security of driver testing process information and synchronously reproducing of the recorded driver testing process information.
When there is no synchronization requirement on the time among the information such as “audio/video stream” and additional “non-audio/video”, the method for synchronously reproducing the multimedia multi-information of the disclosure is adopted. Some “additional information” is added to existing “audio/video stream” or files, such that the corresponding “audio/video stream” or files become carriers of the “some additional information”. Particularly, with respect to a “video file”, when the “video file” merely has “one frame or several frames of videos” or “one picture or several pictures of videos”, the file is the one or several photos or pictures as a matter of fact. That is to say, by utilizing the method for synchronously reproducing the multimedia multi-information of the disclosure, the “additional information” can be embedded into the one or several pictures, such that these pictures become the carriers of the “additional information”.
Specifically, the application includes that: the method for synchronously reproducing the multimedia multi-information in the first example or second example is applied to website security protection, i.e., by adopting the method for synchronously reproducing the multimedia multi-information in the first example or second example and using “audio, video and picture files” to indicate a website, the information to be transferred by the website all are embedded into the “audio/video information streams” or files of the website, so as to prevent the attack and damage of the current malicious software.
Alternatively, the method for synchronously reproducing the multimedia multi-information in the first example or second example is applied to security protection of information transmission, i.e., by adopting the method for synchronously reproducing the multimedia multi-information in the first example or second example, the information to be confidentially protected all are embedded into some “audio/video information streams” or “audio/video information files or picture/image files” for necessary storage or transmission.
Alternatively, the method for synchronously reproducing the multimedia multi-information in the first example or second example is applied to transmitting some customized information in the digital audio/video broadcasting field; and thus, the transmission links and corresponding devices for the customized information may be saved.
According to the embodiments of the disclosure, the embodiment of a method for synchronously reproducing multimedia multi-information is further provided. The method is to respectively convert multi-channel audio information and multi-channel video information, collected concurrently, of a driving test into single-channel audio information HAS and single-channel video information CVS; then store with all non-real-time test information relevant to the driving test, such as testee information, test scores, tester information and test vehicle information to all audio/video monitoring information which carries a testing process of testees and form, in the form of a compressed file, a “driver testing process multi-information audio/video file DEMSAV” which includes various information of the driving testing process; and then synchronously reproduce all information recorded in the “driver testing process multi-information audio/video file DEMSAV” of a multi-information driving test synchronous recording process using a dedicated player capable of synchronously reproducing and playing back the multi-information.
The method mainly includes three steps.
In (1) a step of collecting: the multi-channel audio and multi-channel video are respectively converted into the single-channel audio HAS and the single-channel video CVS.
In (2) a step of storing: the information in the step of collecting is formed into the “driver testing process multi-information audio/video file DEMSAV” which includes the various information of the driving testing process and is stored to a high-capacity data storage.
In (3) a step of synchronously reproducing: the all information recorded in the “driver testing process multi-information audio/video file DEMSAV” of the multi-information driving test synchronous recording process is synchronously reproduced using the dedicated player capable of synchronously reproducing and playing back the multi-information.
According to the method for improving the security of the driving test information and synchronously reproducing the driving test information, the (1) the step of collecting is as follows.
In A, the multi-channel video information, before being stored, is combined into the single-channel video information CVS using a data collection unit (referring to
The method is to simultaneously collect m channels of real-time dynamic video signals of analog video cameras for monitoring a testing process or k channels of digital video cameras for monitoring the testing process and perform digital processing, and at last combine into video signals for later comprehensive processing or simple storing and recording, wherein the combined video signals are able to meet, merely needing one channel, the requirements of a user; the values of the above m and k are as follows: m=0, 1, 2 . . . 8, k=0, 1, 2 . . . 8, and m+k=1, 2, 3 . . . 8.
In B, the multi-channel audio information is mixed into the single-channel audio information HAS using a digital analog unit (referring to
The method is to simultaneously mix n channels of real-time audio signals analog circuit of pickups for monitoring the testing process into single-channel audio signals to output, wherein the single-channel audio signals are able to meet, merely needing one channel, the requirements of the user, and are taken as signal sources for audio digital collection; the values of the n is as follows: n=1, 2 . . . 6.
According to the method for improving the security of the driving test information and synchronously reproducing the driving test information, in the (2) the step of storing, the “driver testing process multi-information audio/video file DEMSAV” which records various information of the driving testing process not only includes the real-time information and the non-real-time information, but also includes the audio/video information and the non-audio/video information; in the process of forming the file DEMSAV, the (2) the step of storing (referring to
In C, the video information CVS and the audio information HAS collected in the step of collecting are digitally compressed first using an audio/video mixer to form audio/video information CAVS which is able to meet the requirements of a certain compression standard, carries all audio/video monitoring information of the testing process of a testee and appears in a compressed form.
In D, the non-real-time test information such as testee information, tester information and test car information except for the test scores is stored to a beginning part of the audio/video information CAVS which carries the all audio/video monitoring information of the testing process of the testee and appears in the compressed form, that is after the testee obtains a test beginning notification and before a formal test beginning process, thereby forming the basic “driver testing process multi-information audio/video file DEMSAV”.
In E, the real-time position value that is a “coordinate” value of the test car, and the real-time non-audio/video monitoring information of relevant real-time information that is required to be stored and recorded when a score deduction point in test judgment occurs are synchronously stored to a position, corresponding to a video frame at that moment, in the basic “driver testing process multi-information audio/video file DEMSAV” which records the CAVS information.
In F, after the test is finished, scores of the testee are timely stored to a corresponding video frame in the basic “driver testing process multi-information audio/video file DEMSAV”, and enable the scores locating in some video frames after the test is finished and before the video recording is stopped, thereby forming the final “driver testing process multi-information audio/video file DEMSAV”.
The playback method for guaranteeing that the driving test information is synchronously reproduced is as follows (referring to
All information in the testing process of the testee is simultaneously and synchronously recorded in the driver testing process multi-information audio/video file DEMSAV which stores the driving test information. However, in reproduction and playback, to achieve the expected effect of an operator or an inquirer, it is necessary to launch the following one or more work.
In G, in an initial stage of the reproduction and playback process, the non-real-time non-audio/video information such as testee information, tester information and test car information in the “driver testing process multi-information audio/video file DEMSAV” which stores the driving test information is gradually separated out one by one using a “driver testing process multi-information audio/video file DEMSAV decoder IV1” first and is placed into a storage buffer area of the player or is stored to a certain specified file for later use when necessary.
In H, as the reproduction and playback process proceeds to gradually enter an operating process in which the testee starts to test, the non-audio/video information is continuously and synchronously separated out from a video frame being played; and meanwhile, the position coordinate values of the test car are depicted to specified positions using corresponding points of a certain coordinate system, so as to form a travelling track of the test car to be presented to an observer and therefore the operator for the reproduction and playback uses it as needed.
In I, in the process of separating and extracting these information using a non-audio/video information separation module (including software, hardware or a device having both), when the score deduction point for the test judgment occurs, a DEMSAV file reproduction and playback module (including software, hardware or a device having both) is able to be notified immediately, i.e., the service can be paused temporarily.
In J, the module (including software, hardware or a device having both) for the reproduction and playback, when receiving a notification that the score deduction point for the test judgment occurs, is paused automatically and temporarily so as to attract the attention of the observer.
In K, the module (including software, hardware or a device having both) for the reproduction and playback, by means of providing relevant services and functions such as receiving, an operation instruction of the operator for the reproduction and playback in real time, is able to be better meet the requirements of the operator and implements functions and services (such as pause, amplification and duplication) expected by the inquirer, such that a friendly man-machine interface is provided for the operator for the reproduction and playback and the operator for the reproduction and playback can provide a relatively considerate operation service for a query requester.

Before the compression processing process, the encryption is performed first, then the non-audio/video information is embedded and at last is sent to a “storing-recording module” or a “file recorder” for storing and recording.
{circle around (2)} The test information of the testee is embedded into a storing frame of the compressed audio/video frame timely and appropriately, such that when the DEMSAV file is played using a universal media player, it is very difficult to find that the test information as a video noise is existed in the DEMSAV file even through with a very careful observation; and therefore, the invisibility of an information storing position is guaranteed.
As a still another transformation of the embodiment of the disclosure, in the playback method for guaranteeing that the driving test information is synchronously reproduced, to guarantee the test information of the testee to be secure and reliable and to improve the security in storage and management of the DEMSAV file, there is a need to adopt the following methods.
{circle around (1)} To achieve the required information storage and reproduction effect, it is essential to use a dedicated DEMSAV file reproduction and playback software or hardware device in the reproduction and playback so as to realize the complete data information reproduction and synchronization effect.

The multi-information mixer BIII2B is a software and hardware processing module capable of mixing graphics, image and text information together and is configured to insert the non-real-time information NRS and the real-time non-audio/video information RNRVS of the “non-audio/video information” into the audio/video information stream CAVS, compressed by the digital information compressor BIII3B, to form a “multi-information audio/video stream CMSAV” including the “non-audio/video information” RNS and RNAS.
The multi-information modulation unit BIIIB first sends the synchronously collected and digitalized “audio/video stream” AVS to the digital information compressor BIII3B for compression to form a compressed information stream of an audio/video mixed information stream CAVS, and then insert the “non-audio/video information” using the multi-information mixer BIII2B, thereby finally forming an audio/video information stream CMSAV or a multimedia multi-information file CMSAVF thereof stored in the “file recorder”, wherein the audio/video information stream CMSAV is able to meet the requirements of a certain audio/video compression standard, carries the non-audio/video and appears in the compressed form.
As a transformation of the embodiment of the disclosure, when the information stream CAVS formed by compressing the “audio/video information” is compressed audio/video information output by an existing device such as network camera and video server on the present market except for the software and hardware module of the disclosure, the embodiment may be simplified to merely comprise the multi-information mixer BIII2B and the multi-information file recorder III4, and the digital audio/video synchronous collector III1, the digital audio receiver III11 and the digital video receiver III12 that are connected with the digital audio/video synchronous collector III1, and the digital information compressor BIII3B module are omitted. The system has the advantage that the information source output by an existing external audio/video device, which is able to output the compressed audio/video information, such as network camera and video server on the present market, may be used as a carrier of “additional information blocks”, such that the software and hardware overhead of the technical device of the disclosure is reduced; in other words, at this moment, the overall cost may be saved.
There are the following several applications of applying the multi-information modulation unit of the first example or the second example to the method for synchronously recording the multi-information.
(1) A simple method for synchronously recording multimedia multi-information for single-channel audio/video information:
{circle around (1)} when there merely has the “video stream” in the “audio/video stream”, the “additional information block” formed by the “non-audio/video information” is inserted in the form of taking an “additional information frame S33x” as a carrier, wherein the “additional information frame S33x” is created between adjacent two frames of the video stream V33x and V33x1 (referring to
{circle around (2)} when there merely has the “audio stream” in the “audio/video stream”, the “additional information block” formed by the “non-audio/video information” is inserted in the form of taking an “additional information frame S34y” as a carrier, wherein the “additional information frame S34y” is created between adjacent two frames of the audio stream A34y and A34y1 (referring to
{circle around (3)} when there simultaneously includes the “video” and the “audio” in the “audio/video stream”, the “additional information block” formed by the “non-audio/video information” is inserted in the form of taking an “additional information frame” as a carrier, wherein the “additional information frame” is created between adjacent two frames of the video stream, or created between adjacent two frames of the audio stream, or created between the adjacent two frames of the video stream and simultaneously created between the adjacent two frames of the audio stream.
The above is the most convenient and direct method for synchronously reproducing the multimedia multi-information and is applied for storing information in various occasions undemanding on the information security.
(2) A safer method for synchronously reproducing multimedia multi-information for single-channel audio/video information:
{circle around (1)} when there merely has the “video stream” in the “audio/video stream”, the “additional information block a” formed by the “non-audio/video information” is embedded into the “video stream” and into an xth video frame corresponding to a time point when the “non-audio/video information” occurs; referring to
{circle around (2)} when there merely has the “audio stream” in the “audio/video stream”, the “additional information block b” formed by the “non-audio/video information” is embedded into the “audio stream” and into a yth audio frame corresponding to a time point when the “non-audio/video information” occurs; referring to
{circle around (3)} when there simultaneously includes a “video stream” and an “audio stream” in the “audio/video stream”, the “additional information block a/b” formed by the “non-audio/video information” is inserted into the “video stream” and into some video frames corresponding to a time point when the “non-audio/video information” occurs, or inserted into the “audio stream” and into some audio frames corresponding to a time point when the “non-audio/video information” occurs, or inserted into the “video stream” and into some video frames corresponding to a time point when the “non-audio/video information” occurs and inserted into the “audio stream” and into some audio frames corresponding to a time point when the “non-audio/video information” occurs (referring to
{circle around (4)} according to the need, the “additional information blocks a1, a2/b1, b2” formed by the “non-audio/video information” may be individually inserted, in the form of taking an “additional information frame S37x” as a carrier, wherein the “additional information frame S37x” is created between adjacent two frames of the video stream V37x and V37x1, into a “video stream” formed by an “Xth video frame” into which the “additional information block a1” has been embedded and an “X+1th video frame” into which the “additional information block a2” has been embedded. Referring to
Alternatively, the “additional information blocks a1, a2/b1, b2” formed by the “non-audio/video information” are inserted, in the form of taking an “additional information frame S38y” as a carrier, wherein the “additional information frame S38y” is created between adjacent two frames of the audio stream V38yx and V38y1, into an adjacent audio frame of an “audio stream” formed by a “yth audio frame” into which the “additional information block b1” has been embedded and a “y+1th audio frame” into which the “additional information block b2” has been embedded. The A38y and A38y1 are all audio information sets of some two frames in the “audio stream” which carries the “non-audio/video information” NAVS. The A38y is the “additional information frame” which is inserted between adjacent two audio frames, carries a “non-audio/video information block” and is independent of the video frames.
According to the need, the above two methods may be employed simultaneously, i.e., the “additional information blocks”, while being embedded into some video frames of a “video stream”, are inserted between adjacent two frames of the “video stream” in the form of taking an “additional information frame” as a carrier, wherein the “additional information frame” is created between the two adjacent frames of the video stream. Furthermore, the “non-audio/video information” is not only take as the “additional information blocks” to be embedded into some audio frames of an “audio stream”, but also inserted between adjacent two frames of the “audio stream” in the form of taking an “additional information frame” as a carrier, wherein the “additional information frame” is created between the two adjacent frames of the audio frame (referring to
