TL;DR: This paper describes two desired properties of a set of image processing operations, namely minimality and independence, and demonstrates methods for testing for each of them.
Abstract: Instead of saving multiple versions of a large multimedia data file, it is more efficient to store only the instructions used by the editors to create the different versions. To uncompress files stored in this manner, the editor would simple perform the listed instructions. For these files to be portable, however, the set of operations used in the instructions must be standardized. To standardize a set of operations, there must be some criteria developed for the inclusion of each operation. This paper describes two desired properties of a set of image processing operations, namely minimality and independence. In addition, this paper demonstrates methods for testing for each of them. 1. MOTIVATION Multimedia data can be categorized into various types such as audio, video, still images, text, and graphics. The one common attribute of all of these data types is that they all require large amounts of space (Khoshafian and Baker, 1996). For example, CD quality audio uses 1.4 Mb per second, NTSC quality video uses 1.92 Mb per frame, and an image stored as a bitmap can require 4,000,000 bytes (Aberer and Klas, 1992, Woelk, et. al, 1990). One of the functions of a Multimedia Database Management System (MMDBMS) is to allow users to arbitrarily edit multimedia data (Grosky, 1994). The enormous size of the multimedia data described above causes problems for the database systems that must maintain it. To illustrate these problems, we will consider three example applications. The first application is one for an interior designer. This application would allow the designer to decorate a room by editing a photo of it. Among the changes the designer could make are changing the color of the walls and carpet; adding, removing, or rearranging the furniture; and, finally, changing the lighting in the room. The designer will also want to save several different versions of the room and be able to retrieve them to show to the customer. The second example application is one for a recording studio. This application would allow producers to enhance a recording by adding different sound effects to it. In addition, the producers could add other voices or sample from other songs to the recordings. The producers, of course, will want to save several different versions of the recordings to determine the ones that are the best to sell. The final example is an application for the development of large scale software. During the coding and testing phases of the development, several modifications will be made to the source code. While debugging, the programmers will need to

TL;DR: The Multimedia Systems journal identifies this area as a significant research topic and invites original, unpublished contributions highlighting the issue, research results or applications in the area of Content Based Retrieval.
Abstract: Content analysis and understanding is an emerging area of multimedia research. Multimedia database applications are ready to leapfrog from handling simple BLOBS to retrieving information based on content understanding. The Multimedia Systems journal identifies this area as a significant research topic and invites original, unpublished contributions highlighting the issue, research results or applications in the area of Content Based Retrieval.

TL;DR: In this paper, a single-chip but multi-output graphic system which provides identical or different graphic images on two display screens is presented, where the first input process router selects the backdrop graphics and the moving object graphics (which are both provided by the multimedia database), feeds them into the first graphic processing unit and then outputs the processed graphics onto either the first display unit or the second display unit.
Abstract: The present invention provides a single-chip but multi-output graphic system which provides identical or different graphic images on two display screens. The graphic system comprises at least a multimedia database, a first input process router, a second input process router, a first graphic processing unit and a second graphic processing unit. The first input process router selects the backdrop graphics and the moving object graphics (which are both provided by the multimedia database), feeds them into the first graphic processing unit and then outputs the processed graphics onto either the first display unit or the second display unit. Similarly, the second graphic processing units processes the backdrop graphics and the moving object graphics selected by the second input process router and then outputs the process graphics onto either the first display unit or the second display unit.

TL;DR: The paper presents several aspects of design techniques giving a unified composition, modularity of the application and navigation standards within the product.
Abstract: Data files available on Web server contain very often various data formats linked into a composition producing sequence presented frame by frame as a movie. The multimedia database design methods have to consider many rules that must be integrated to obtain standards for simplifying development of the application and for fast exploration of the product. The paper presents several aspects of design techniques giving a unified composition, modularity of the application and navigation standards within the product. The database is accessed in a remote server of the computer network.

TL;DR: In this article, a distributed server system for transmitting multimedia data and a method thereof are provided to distribute DB servers for providing multimedia data, switching servers and feeding servers for streaming the multimedia data using a memory pool and a pool buffer.
Abstract: PURPOSE: A distributed server system for transmitting multimedia data and a method thereof are provided to distribute DB servers for providing multimedia data and switching servers and feeding servers for streaming the multimedia data, so as to correct a transfer rate based on the distributed servers and manage stream multimedia data using a memory pool and a pool buffer. CONSTITUTION: A mobile communication client(500) delivers client packets including distributed server identification information, multimedia data streaming request information and mobile communication terminal location information, and receives multimedia data in real time to provide the mobile communication terminal(600) with the received multimedia data. At least one distributed parallel switching server(300) connected to the mobile communication client(500) through a wired network(400) receives the client packets and delivers the client packets to other distributed servers according to the distributed server identification information, receives multimedia data and manage the multimedia data through a pool buffer. Also, the switching server(300) allocates lines and controls connection to transmit the multimedia data to the mobile communication client(500). At least one distributed parallel feeding server(200) receives and processes the client packets from the switching server(300), and requests multimedia data search to receive and store the searched multimedia data. Also, the feeding server(200) manages the stored multimedia data through the pool buffer, and generates control packets including control codes and server packets including multimedia data to transmit the generated packets to the switching server(300) while maintaining a regular rate. And at least one distributed parallel DB server(100) including a multimedia database searches and provides the multimedia data upon the search request of the feeding server(200), and has a management panel for storing, deleting and modifying the multimedia data.
