Multimedia multi-information synchronized reproducing system

Abstract

A multimedia multi-information synchronized reproducing system comprises a multi-information modulation unit, a multi-information synchronized reproduction unit and a hardware platform of the system, wherein the multi-information modulation unit is a component used for combining multiple pieces of relevant information with associated information relation, that is, interpolating ''non-audio, non-video information'' into ''audio and video stream or files thereof'' to form a ''multimedia multi-information file CMSAVF''; the multi-information synchronized reproduction unit is a component used for reproducing and backplaying the ''multimedia multi-information file CMSAVF'', carrying the ''non-audio, non-video information'', after demodulation via a ''multi-information file demodulator''; and the hardware platform of the system is a software and hardware platform with a modulator-demodulator used for producing and restoring various kinds of information exist in the ''multimedia multi-information file CMSAVF''. The multimedia multi-information synchronized reproducing system can store multimedia multi-information files in a same document file synchronously in real time, and ensures that the files can be highly synchronized in query and playback.

Description

technical field [0001] The invention relates to a device used in a method for synchronously reproducing different types of information, in particular to a system for synchronously reproducing multimedia and multi-information. Background technique [0002] When storing, replaying, retrieving, and inquiring about the collection of multimedia information involving sound, image, text, whereabouts, and behavior information, it is currently necessary to use a variety of software and hardware equipment systems and means and methods to achieve the goal. [0003] 1. Common multimedia information collections include: [0004] (1) The information contained in the Ministry of Public Security on the 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 monitorin...

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 one-to-one correspondence in terms of time. Therefore, no matter in theory or in practice, it is impossible to solve the problem of synchronizing information such as sound, image, and picture with corresponding non-sound, image, and picture information during playback, such as:

[0043] Multiple information files are required to record the driver’s driving skill test process. When it is necessary to reproduce the video and driving track, the out-of-sync phenomenon is particularly prominent, and only asynchronously The time difference between the depicted driving trajectory and the video signal recorded by the test vehicle in real time is uncertain and cannot be controlled at all, which can easily cause visual errors and make the observer think it is a kind of judgment when there is a judgment point. Mistakes, which may even lead to doubts or disputes over correctness;

[0044] When conducting pre-registration medical examinations for those who need to register to learn motor vehicle driving skills, in order to prevent unhealthy trends, prevent fraud, and ensure fairness and notarization, the new standard stipulates that In order not to allow the medical examination institutions designated to be set up inside the vehicle management office under the real-time supervision of the police of the vehicle management office to carry out corresponding work, but to allow the neutral hospital with medical examination qualifications that cannot be directly intervened by the vehicle management office to conduct medical examinations as a third party Yes, at this time, in order to ensure the authenticity of the medical examination results and implement effective process supervision, it is necessary to combine audio and video information as evidence. At this time, there will be obvious time asynchronous problems in the information reproduced during the supervision and inspection

[0045] (2) When the current database technology is used to store static information and dynamic information such as real-time moments, due to the universality of the interface and the openness of the technology, its If the security is not guaranteed, it will be easily tampered by criminals, thus destroying the authenticity of 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.
