Multimedia Database

Slide 2: 

Presented & performed by Arunachalam. PL COMPUTER ENGINEERING

Slide 4: 

Introduction Media refer to the types of information such as alphanumeric data, images, audio, and video. MMDBMS provides facilities for traditional DBMS functions like database creation data modelling data retrieval data access and organization data independence.

Slide 5: 

As multimedia data is large and will affect the storage, retrieval and transmission of multimedia data. Multimedia data structures are completely different from standard database. In case of video and audio databases time to retrieve information may be critical ex (Video on demand) Need for multimedia

Slide 6: 

As the name implies, multimedia comprises many kinds of media, including image, video, audio, graphics, animation, hypertext, and hypermedia. Media objects are similar to Java or C++ classes, to describe image, audio, and video data. Multimedia objects

Slide 7: 

A digital image consists of attributes that describe the characteristics of the image, and the image data itself the digitized bits Attributes: * Size (height in scan lines and width in pixels) * Number of bits per pixel in each of the colors sampled * Compression type * Content format objects TYPES Image type

Slide 8: 

Audio and video services provide the foundation for digital audio and video data in databases. Attributes: * Source type, location, and name * Description * File format * Number of audio channels * Sample/frame rate and sample/frame size * Frame resolution and total number of frames * Number of colors * Bit rate * Duration object TYPES Audio & Video types

Slide 9: 

requirements Integration Data items do not need to be duplicated for different programs Data independence Separate the database and the management from the application programs Concurrency control Allows concurrent transactions Persistence Data objects can be saved and re-used by different transactions and program invocations

Slide 10: 

Privacy Access and authorization control Integrity control Ensures database consistency between transactions Recovery Failures of transactions should not affect the persistent data storage Query support Allows easy querying of multimedia data Conn…

Slide 11: 

Mm database architecture Based on Principle of Autonomy

Slide 12: 

Based on uniformity

Slide 13: 

Image database architecture

Slide 14: 

Distributed multimedia dbms

Slide 15: 

ARCHIVAL IN THE DATABASE Two Structures: Un Structured- A method in which data can’t be retrieved by accessing structural detail. Structured- Data’s are stored in variables with corresponding value.

Slide 16: 

OPERATIONS IN THE DATABASE Input Write data to Database Output Read data to Database Modification Conversion & modifying data format in Database Deletion Removes a data from Database Comparison Matching of content in Queries with Database

Slide 17: 

RETRIEVAL FROM THE DATABASE Automatic Keyword Annotation

Slide 18: 

Keyword Based Retrieval

Slide 19: 

Functions Multimedia database can be used in distributed system which helps in online database transaction Digital records subsystem be able to paper, picture, tiny film, video tape, audio tape and others. It provide fast data transaction.

Slide 26: 

Multimedia technologies are attracting more and more interest every day. Multimedia-on-Demand is one of the buzzwords today and is now available for the public. As a consequence, content providers such as publishers and broadcasting companies must be able to archive and index their productions for later retrieval. The research on multimedia database has become an important issue in the community of multimedia computing. Future MMDBMS applications will be have effective instance, intelligent agents, based on Artificial Intelligence techniques, will further assist multimedia database software to interact with its users Let us conclude…
