KR20030013064A - MPEG Compression - Google Patents

Abstract

PURPOSE: A motion picture compression protocol is provided to construct a multimedia information search system and offer super-high-speed motion pictures with high picture quality. CONSTITUTION: Information about all of blank spaces with respect to colors and resolution is encoded in 1 bit (2 byte) and stored. The encoded data is transmitted to a virtual memory. The original motion picture is reproduced from the encoded motion picture image.

Description

Video Compression Protocol {MPEG Compression}

MPEG-1, 2, 3, 4, 7, Tcp / Ip

Available fields include (1) Digital Libraries such as Image Catalog and Musical Dictionary, (2) Multimedia Directory Services such as Yellow Pages, (3) Radio Channel, Broadcast Media Selection on TV channels, and (4) Personalized Elec-tronic. There are many areas such as News Service or Multimedia Editing that enables Media Authoring.

Applications can be divided into Pull, Push, and other applications. Pull application services include storage and retrieval of video databases, web-based audiovisual search, audiovisual repositories, professional media production and video transmission, and music services such as commercial karaoke and record sales. Push applications are more like broadcast and webcasting concepts. The focus here is on selection and filtration rather than the concept of indexing and extraction.

Examples of push applications include personalized television services in the form of NVOD (Near Video on Demand), intelligent multimedia presentations, and multimedia broadcasting data browsing, filtering and retrieval based on user's personal preference. In addition to other applications, Tele Shopping, which increases product purchasing power with visual information, Bio-medical field for medical diagnosis, remote sensing using a large amount of image database, multimedia data universal access adapting to client's environment, interactive education Many applications, including educational applications to create environments, multimedia editing to easily edit videos in a variety of ways, from editing professionals in professional studios to novice users in the home, and surveillance-based controls. There is a field.

The main functions of Cinema Paradise include feature and text index for video information, automatic segmentation of MPEG video scene in compressed area, feature based search, search by natural language query, key fact based search and SQL search.

Cinema Paradise's feature adopts algorithm that performs automatic segmentation, feature extraction, and retrieval of MPEG-1 1,2 video in the compression domain. In particular, this technology is currently under consideration under the proposal of MPEG-7 standardization technology. In addition, the key fact information retrieval function was introduced to increase the accuracy of the retrieval. This is a search function that considers the property of an object and is a suitable query method for finding multimedia data.

Based on this technology, we are developing an image index and search engine, an automatic MPEG video cutover recognition engine, a content-based video information search engine, a keyword text information search engine, and a key text text information search engine.

Describe compression method

Converter Program It is composed of one file, and through this converter, many video files such as AVI, MPeG, and Vob can be transferred 30 frames per second in a conventional transmission method.

The transmission speed is about 1MCps based on 128k.

The multimedia information retrieval system can be constructed.

It can provide high quality ultra high speed video for MIT2000.
