Description Schemes (DSs) can be used for searching, filtering and browsing multimedia material. Since they provide a more complex data model for content description than Descriptors, they are particularly useful in producing rich descriptions of the multimedia content that involve a number of Descriptors and DSs.

Multimedia Description Schemes refer to specific MPEG-7 metadata structures that are used to describe and annotate multimedia data. The Multimedia Description Schemes are categorized as pertaining to visual, audio, or generic description. In general, the Multimedia Description Schemes can contain MPEG-7 Descriptors and other Description Schemes (DSs) and can be extended for domain-specific applications.

Multimedia Description Schemes provide a way to describe in XML the important concepts related to multimedia content. The Multimedia Description Schemes facilitate the searching, indexing and filtering of multimedia data. Many of the multimedia concepts are defined in the MPEG-7 Principal Concepts List. The Description Schemes (DSs) are designed to describe both the generic aspects of multimedia content management and the specific features of multimedia content.

Description Schemes (DSs) are defined using the MPEG-7 Description Definition Language (DDL). DDL is based on XML-schema. DDL allows the creation and extension of DSs.

Multimedia Description Schemes provide a standard set of data types and description structures needed for generating XML descriptions of multimedia content. The descriptions are human-readable and can be searched, transmitted and filtered in applications that deal with multimedia data.

The full set of Multimedia Description Schemes, which are related to each other through linking, form a data model or schema for multimedia content description. At both the conceptual- and implementation-levels, the data model is object-oriented and employs modeling principals such as generalization, association, aggregation and spatio-temporal composition. The instantiation of the Description Schemes (DSs) results in description data that is in XML format.

The MPEG-7 Multimedia Description Schemes (MDS) specification advanced to the Final Draft International Standard (FDIS) stage in July, 2001. The MPEG-7 International Standard is currently under production by ISO. Proposals are currently being made for new tools for MPEG-7 MDS version 2.

The Multimedia Description Schemes are validated using one of two procedures depending on the type of Description Scheme (DS). First, the specific DSs related to content management, creation, production and usage go through a "harmonization" process in which the important concepts for description are identified and verified in other multimedia data standards and existing practices.

Many Description Schemes (DSs) are computed automatically by processing the multimedia data directly, such as by using feature extraction algorithms or content analysis methods. Other descriptions are generated manually by human annotation or by processing external metadata related to the multimedia material.

The MPEG Description Definition Language (DDL) can be used to define, extend and generate new Description Schemes (DSs) as shown in the following picture. By using the object-oriented aspects of the DS model, it is possible to extend the DSs to develop customized, application specific DSs that are outside of the MPEG-7 standard.

Although there is no formally stated distinction, generally, MPEG-7 Descriptors address the low-level perceptual features of multimedia data and are meant to be extracted automatically. In many cases Descriptors correspond to the perceptual attributes of multimedia data and its regions and segments, such as to describe the color of a region.

First of all, it is not too late to propose new Multimedia Description Schemes. Work on MPEG-7 MDs version 2 is underway. The standardization process requires that an initial proposal be made to MPEG for the specific Description Scheme (DS). The presentation made to the MPEG Multimedia Description Schemes (MDS) Group should identify sufficient reason and evidence for needing the DS.

The Final Draft International Standard (FDIS) of the MPEG-7 Multimedia Description Schemes includes many Description Schemes (DSs), which have been validated in the work of the Multimedia Description Schemes (MDS) Group since 1999. A number of additional DSs are currently being examined in the process of core experimentation for possible inclusion in MPEG-7 MDS version 2.0.

If you are a member of MPEG, you may join the Multimedia Description Schemes (MDS) Group by joining its meetings which are held at the MPEG meetings. You may also participate in one of the MDS Ad Hoc Groups (AHGs), subscribe to one of the MDS reflectors, or participate in a Core Experiments (CEs).

The major applications of Multimedia are: - a) To create Computer Based Training b) To create interactive web contents with sound and movie files. c) To create Multimedia presentation for marketing and promotional aids. d) To create informative Kiosk etc.,

If you have never used a multimedia CD-ROM program before, relax and take your time. Listen, read and watch for instructions. Use your mouse. You are about to experience the reality of multimedia learning. There will be video, animation, graphics, audio, and text happening before you. This is all captured on a little disc, easily accessible whenever and wherever you need it.

Until recently, nearly all users faced the same pricing structure for Internet usage. A fixed-bandwidth connection was charged an annual fee, which allowed for unlimited usage up to the physical maximum flow rate (bandwidth). We call this ''connection pricing''. Most connection fees were paid by organizations (universities, government agencies, etc.) and the users paid nothing themselves. Simple connection pricing still dominates the market, but a number of variants have emerged.

c Displays the date, followed by the time. The time is not displayed if the date-time value indicates midnight precisely. e Displays the year in the current period/era as a number without a leading zero (Japanese, Korean and Taiwanese locales only). ee Displays the year in the current period/era as a number with a leading zero (Japanese, Korean and Taiwanese locales only). m Displays the month as a number without a leading zero (1-12).

A Multimedia Description Scheme Core Experiment (CE) is a particular kind of experiment in which competing proposals for Description Schemes (DSs) are compared. The situation may arise when a new proposal is made with the intention of revising, replacing, or removing a DS that is in the MPEG-7 Multimedia Description Schemes (MDS) Working Draft (WD). A CE represents a head-to-head competition in which the alternative proposals are evaluated based on the comparative advantages.

The reviewers are looking for convincing evidence that the applicant is an exceptionally creative new investigator who is proposing an innovative approach with the potential to produce results that will have an unusually high impact on a significant problem in type 1 diabetes research. They will also assess the appropriateness of this application for the Type 1 Diabetes Pathfinder Award process rather than the standard peer review process. For more detail, see RFA Section V.2.

Both video playback (VHS and DVD) and computer projection are available. We also have provision for a laptop computer input. Finally, we have an overhead visual presenter. All equipment is controlled by an AMX touch screen control panel.

the Entertainment industry goes digital, it is creating a wider berth for the use of multimedia, in fact, relying extensively on this technology for its techno look and feel, Whether it is the area of the film making, pre- and postproduction, creation of special effects or animation, multimedia technologies have pervaded the entertainment sector.

Sure, just edit or combine the HTML needed for Cocoa with the HTML needed for whatever other web multimedia that you want to put on your page.

There are separate color schemes used for varying groups of elements. The colors were selected based on general conventions for some element groups, ease of reading, and lack of conflict with metadata colors (e.g., for counties, lakes, etc.) ArcExplorer supports the customization of these colors (see ArcExplorer documentation).

The Multimedia Description Schemes (MDS) Group is a working group of MPEG formally established in July, 1999 to develop Multimedia Description Schemes as Part 5 of the MPEG-7 "Multimedia Content Description Interface" standard. The MDS group is currently working on MPEG-7 and MPEG-21 standards.

The Multimedia Description Schemes (MDS) Group is made up of about 40-50 people that attend the MPEG meetings and >200 people that participate in the various MDS Group Ad Hoc Group mail reflectors. The members represent a significant diversity of interests including content providers, software companies, hardware manufacturers, research organizations, and academic institutions.

Multimedia is made possible by building a "digital engine". This engine allows many different parts (video, audio, and graphics) to interact and produce a multimedia experience on-screen. Sometimes, however, the parts will 'collide' and the screen may not react as it should. This is normal and expected, so relax and continue if you come across minor technical 'hiccups'.

To activate a scheme, just open it in the Finder by double-clicking its icon, as if it were a normal document. (If you get a message saying that the application or translators could not be found, just rebuild the desktop, or open up the Extensions folder and double-click the Kaleidoscope Extension once.) If you put your schemes in the Apple Menu Items folder or a subfolder, you can switch schemes by choosing them from the Apple menu.

Yes. The scheme file format is designed to be easy to edit using ResEdit. See the accompanying documentation in the "Kaleidoscope Goodies" for more information on the scheme format. There are also several third party guides and utilities for creating schemes available on the Kaleidoscope Scheme Archive.
