This document specifies an RTP payload format for the transmission of 3GPP (3rd Generation Partnership Project) timed text. 3GPP timed text is a time-lined, decorated text media format with defined storage in a 3GP file. Timed Text can be synchronized with audio/video contents and used in applications such as captioning, titling, and multimedia presentations. In the following sections, the prob...

A multimedia database system deals with the storage, manipulation and retrieval of digitally representable information objects such as text, images, video and audio [1]. Providing mechanisms that allows the user to retrieve desired multimedia information by their semantic content is now an important issue in multimedia database systems. However, current products (e.g., Oracle 9i interMedia and ...

Synchronization is widely regarded as a fundamental problem in multimedia systems. One can distinguish between two levels of multimedia synchronization, continuous synchronization and event-based synchronization. While the first one aims at the synchronized play-out of data streams, the latter ones orchestrates the presentation of possibly distributed multimedia objects. Multimedia objects may ...

In this paper we describe ongoing work in protocol support for distributed multimedia applications. This work concerns the provision of suitable transport mechanisms to convey multimedia information (text, and digital voice and video) between multimedia workstations in a distributed system. There are two parts to the Lancaster multimedia work. First, we have developed an abstract model for mult...

Humans primarily resort to text or words to describe or present their thoughts when concerning themselves with various forms of multimedia content, such as visual (images or videos) or acoustic (music, etc.). Thus the task of associating text descriptions with images or videos is germane to any human-interpretable discourse around visual multimedia data. Therefore, the multimedia community has ...

Advances in multimedia acquisition and storage technology have led to tremendous growth in very large and detailed multimedia databases. If these multimedia files are analyzed, useful information to users can be revealed. Multimedia mining deals with the extraction of implicit knowledge, multimedia data relationships, or other patterns not explicitly stored in multimedia files. Multimedia minin...

Computer-based multimedia learning environments — consisting of pictures (such as animation) and words (such as narration) — offer a potentially powerful venue for improving student understanding. How can we use words and pictures to help people understand how scientific systems work, such as how a lightning storm develops, how the human respiratory system operates, or how a bicycle tire pump w...
