Method for synchronously reproducing multimedia multi-information and application thereof

Abstract

A method for synchronously reproducing multimedia multi-information is to combine a plurality of relevant documents and a plurality of information flows, which have associated information relation via a multi-information modulation unit, and to synchronously reproduce with a player which can be used for synchronously reproducing multi-information. The step of synchronously recording multi-information of the method is to insert non-audio and video information in audio flow, video flow or file before condensing or after condensing with the multi-information modulation unit, that is to say to embed needed video frame or audio frame in an additional information block carried with the non-audio and video information and / or creating or inserting an additional information frame carried with the non-audio and video information among the needed video frame and the needed audio frame. The method can be used for simultaneously storing a multimedia multi-information file in same file in real time and ensure highly synchronization when inquiring and playing back.

Description

technical field [0001] The invention relates to a method for synchronously reproducing different types of information, in particular to a method for synchronously reproducing multimedia and multi-information and its application. Background technique [0002] When storing, replaying, retrieving, and querying a collection of multimedia and multi-information involving sounds, images, texts, whereabouts, and behaviors, it is currently necessary to use a variety of software and hardware equipment systems as well as means and methods to achieve the goal. . [0003] 1. Common multimedia multi-information collections include: [0004] (1) Information contained in the Ministry of Public Security's process of obtaining and testing motor vehicle driving licenses: [0005] 1.1. No less than two channels of real-time video information; [0006] 1.2. Real-time audio information in the test cab; [0007] 1.3. Real-time dialogue information between examiners and candidates in the monito...

Problems solved by technology

[0042] (1) When tracing the source of process information, it is necessary to use a variety of system methods that do not have a one-to-one correspondence in time. Therefore, it is impossible to solve the problem of sound and image during playback, both in theory and in practice. , pictures and other information and the corresponding non-sound, non-image, non-picture information and other information synchronization issues, such as:

[0043] When recording the driver's driving skill test process, multiple information set files are required. When it is necessary to reproduce the video and driving track, the out-of-sync phenomenon is particularly prominent. The driving track that can only be drawn asynchronously and the video signal recorded in real time by the test vehicle The time difference between them is uncertain and cannot be controlled at all, which can easily cause visual errors. When there is a point of deduction for judgment, it will make the observer think it is a judgment error, and even cause doubts or disputes about the correctness;

[0044] When conducting pre-registration medical examinations for those who need to sign up to learn motor vehicle driving skills, in order to prevent unhealthy trends, prevent fraud, and ensure fairness and notarization, the new standard stipulates that designated settings under the real-time supervision of the police of the vehicle management office are not allowed. The physical examination agency within the DMV conducts the corresponding work, but lets a neutral hospital with medical examination qualifications that cannot be directly intervened by the DMV conduct the physical examination as a third party. At this time, in order to ensure the authenticity of the physical examination results and implement effective measures Process supervision needs to be combined with audio and video information as evidence. At this time, there will be obvious time asynchronous problems in the reproduced information during the supervision and inspection: the medical examination results expressed in words and the audio and video of the medical examination process are not fixed. time relationship

[0045] (2) When the current database technology is used to store the static information and dynamic information that occurs at any moment, due to the universality of the interface and the openness of the technology, its security cannot be guaranteed, and it will be easily used by criminals. tampering, thereby destroying the authenticity of the information data

[0046] (3) When using the current database technology to store static information that has nothing to do with time and dynamic information that has a one-to-one correspondence with time, save them in multiple Among different types of files, it is very troublesome to search, more labor-intensive and time-consuming, and it is even more difficult to reproduce synchronously, and sometimes the time difference even exceeds 10 minutes.
