Discussion of indexing moving image documents at the shot level focuses on a study conducted at the National Film Board of Canada. Popular terms supplied by users were compared with terms assigned by professional indexers in the source stockshot collection. Results suggest that indexing images using preiconographic (ofness) and iconographic…

Discusses movie on demand (MOD) servers, which are computer systems that store movies in compressed digital form for broadcast cable television systems. Highlights include network bandwidths, a disk-based storage architecture for a MOD server, implementing VCR (video cassette recorder) functions to movie viewing, and buffers. (LRW)

Discusses the movement toward digital-based platforms including full-motion video for multimedia products. Hardware- and software-based compression techniques for digital data storage are considered, and a chart summarizes features of Digital Video Interactive, Moving Pictures Experts Group, P x 64, Joint Photographic Experts Group, Apple…

The integration of optical disk systems employing WORM (Write Once Read Many) technology with CD-ROM systems can enhance information management. Two integrated system applications are the Paperless Ship Project of the U.S. Navy and the FEDLOG (Federal Logistics Data on CD-ROM) of the Defense Logistics Agency. These initiatives are described and…

Discusses the necessity of preservation and conservation activities in school libraries to save materials such as school newspapers, programs of events, censorship records, board activities, yearbooks, and student projects. Topics discussed include brittle, deteriorating paper; monitoring the physical environment, including heat, light, humidity,…

Discussion of indexing needs for film and video images focuses on appropriate access points for the storage and retrieval of individual shots which have not yet been included in a production. A study at the National Film Board of Canada is described that investigated ways to index non-art images. (18 references) (LRW)

Presents a new image compression algorithm that employs some of the most successful approaches to adaptive lossless compression to perform adaptive online (single pass) vector quantization with variable size codebook entries. Results of tests of the algorithm's effectiveness on standard test images are given. (12 references) (KRN)

Evaluates the performance of different methods of data compression coding in several situations. Huffman's code, arithmetic coding, fixed codes, fast approximations to arithmetic coding, and splay coding are discussed in terms of their speed, memory requirements, and proximity to optimal performance. Recommendations for the best methods of…

Presents two new algorithms for performing arithmetic coding without employing multiplication and discusses their implementation requirements. The first algorithm, suitable for an alphabet of arbitrary size, reduces the worst case excess length to under 0.8%. The second algorithm, suitable only for alphabets of less than 12 symbols, allows even…

Presents an inference algorithm that produces a weighted finite automata (WFA), in particular, the grayness functions of graytone images. Image-data compression results based on the new inference algorithm produces a WFA with a relatively small number of edges. Image-data compression results alone and in combination with wavelets are discussed.…

Describes the collection of the Local History Department of the Central Library in Aberdeen (which includes 2,300 volumes of locally produced newspapers and 101,000 sheets of press cuttings) and the use of an optical disk system to help solve the problems of storage and access to these materials. (CLB)

Explores the use of analog optical disks as a practical, cost effective means of building picture databases. Questions that should be asked to determine whether optical disk is a suitable picture storage alternative for a particular application are identified and three implementation issues--imaging, indexing, and integrating--are discussed. (CLB)

Examines the use of automated storage and retrieval systems in industry and in libraries. Highlights include intellectual content; and a system being built for the University of Nevada Las Vegas that takes into account selection criteria, limited stack space, and storage of federal depository materials. (LRW)

Explains the Resource Description Framework (RDF), an infrastructure developed under the World Wide Web Consortium that enables the encoding, exchange, and reuse of structured metadata. It is an application of Extended Markup Language (XML), which is a subset of Standard Generalized Markup Language (SGML), and helps with expressing semantics.…

Originally written in the 1950s, this article addresses the question of subdividing and grouping entries under a given author as a main entry that paved the way for the American Library Association's Catalog Code Revision of 1967. It also includes referee responses by Elaine Svenonius, Allyson Carlyle, and Michael Carpenter. (LRW)
