数字化视频作为一种含义丰富的介质,越来越引起人们的重视,并在视频点播、交互式视频服务和远程教育等许多领域得到了应用。今后,随着对视频媒体应用的广泛开展,编制丰富的视频节目将变得更加重要。将众多的视频素材有效的管理,实施有效的编辑将成为重要的课题。这就要求我们对视频内容按一定的方式组织存储,并要提供一个有效的检索机制。
Internet的发展更突出了视频信息在Web应用中的价值,现有的Web应用绝大多数将图像、音频、视频等多媒体信息存在文件系统中,其优点是操作简单,速度快,缺点是管理复杂,尤其是管理大量视频数据时就受到目录数等的限制。如果将它们保存在数据库中,由数据库来统一维护.统一备份,这样就可以简化管理。
近年来,多媒体数据库的引入对数据的管理方法提供了新的思路。我们知道,传统数据库的模型主要针对整数、实数、定长字符等规范数据。数据库的设计者必须把真实的世界抽象为规范数据,而抽象得到的结果往往会损失部分的原始信息,甚至会出现错误。当图像、声音、动态视频等多媒体信息引入计算机之后,可以表达的信息范围大大扩展,但又带来许多新的问题。在这种情况下,如何使用数据库系统来描述这些数据呢?另一方面,传统数据库可以在用户给出查询条件之后迅速地检索到正确的信息,但那是针对使用字符数值型数据的。现在,我们面临着这样的问题:如果基本数据不再是字符数值型,而是图像、声音,甚至是视频数据,那我们将怎样检索?如何表达多媒体信息的内容?我们应该如何组织这些数据呢了查询应该如何进行?本文通过运用SQL server 2000和C++ Builder工具,实现对多媒体数据,进行管理和查找。

The digitized video frequency took one kind of meaning rich medium, more and more brings to people's attention, and in the video on demand, the interactive video frequency service and the distance learning and so on many domains obtained the application. From now on, along with widely will develop to the video frequency media application, establishes the rich video frequency program to change importantly. The multitudinous video frequency source material effective management, will implement the effective edition to become the important topic. This requests us to save to the video frequency content according to the certain way organization, and must provide an effective retrieval mechanism. The Internet development has highlighted the video information in the Web application value, the existing Web application overwhelming majority the picture, the audio frequency, the video frequency and so on in the multimedia information existence filing system, its merit dispatches Chuang nationality horsefly fruit pulp barium gun luxuriant Cong Ying? to circle the gun luxuriant bottle thirsty long-drawn-out stool this to shed luck Ke Ji? south the magpie stubborn to dive 4 to favor jokes the hut school soil moisture to bestow gallops shakes ? The unified backup, like this may simplify the management. In recent years, multimedia database introduction logarithm according to the management has provided the new mentality. We knew that, the traditional database model mainly aims at the integer, the real number, the fixed length word symbol and so on the standard data. The database designer must be abstract the real world is the standard data, but abstractly obtains the result often can lose the partial primary information, even can appear the mistake. After picture, sound, dynamic video frequency and so on multimedia information introduction computer, may express range of information big expansion, but brings many new questions. In this kind of situation, how uses the database system to describe these data? On the other hand, the traditional database may produces the inquiry condition after the user rapidly retrieve the correct information, but that is aims at the use character value according to. Now, we are facing such question: If the master data no longer is the character value, but is the picture, the sound, even is the video frequency data, how then we will retrieve? How expresses the multimedia information the content? How should we organize these data inquiries to be supposed how to carry on? This article through utilizes SQL server 2,000 and C++ the Builder tool, realizes to the multimedia data, carries on the management and the search.

The arithmetic figure 化 sees the 频 to be used as a kind of what meaning enrich to lie the quality, and more and more cause people thoughtful of, and combine at see the 频 point to sow, hand over with each other the type saw the 频 to serve to educate with long range to wait the many realm to get the application. 频 contents that from now on, along with right see the 频 medium to apply extensive to open the exhibition, what establishment enrich to see the 频 program to will become the much more importance.Will numerous see the 频 material the management that validate, and into practice the valid editor will become the importance's lesson. This will beg us right see the way to press certain buildup the 存储 , and combine the inspectional mechanism of to provide a validity.
The Internet development is more outstandinged to see the 频 information to apply the inside's value, current Web to apply the great majority to resemble the diagram in the Web, 音频 , see the 频 etc. The multi- Media information the esse in the document system, its advantage is an operation simple, speed quick, the weakness is a management complicacy, particularly manage the large quantity to see the 频 data suffer the catalogue the restrict of few etc.s. if keep they in the database, be simplified like this by the database come unifying the maintenance. unify the backup, can management.
Model that In recent years, management method that multi- Media database that 引 is into the logarithms according to provided the new way of thinking. We know, and the traditional database primarily aim at the integral, real amount, settle the long word the 符 etc. Information scope that the norm data.World abstraction that result that the database's design must is a norm data the true, but the abstraction get and would usually lose the part's primitive information, would even appear the mistake. The diagram resemble, voice, after development see the 频 etc. The multi- Media information the 引 into the calculator, can the expression consumedly expand, but again bring the new problem of lots of.In that case, how to use the database system to describe these datas?On the other hand, the traditional database can quickly inspect the right information after customer give out the search term, but that is what aim at to use a word 符 number type data. now, we face the such problem: If the basic data no longer is a type of a 符 number, but is a diagram to resemble, voice, even see the 频 data, that we will be how inspectional?How to expresses the contents of the multi-media information?How should we organize these datas how should search proceeds?This text passes to make use of the SQL server 2000 with the C++ Builder tool, realize to multi-media data, proceeds to manage with check to seek.
