This paper discusses an experimental prototype system for presenting integrated multimedia documents over a digital network. This prototype is the first in a series mvesttgating the requirements placed on the network in support of applications presenting multimedia information. The information consists of multiple media in digital form, including multi-font text, geometric graphics, photographic images, audio and motion video. The paper describes the motivation for this line of research and the initial focus and goals of our first totypg_. We describe the hardware comprising this prototype and the current status of our efforts. s is followed by a discussion of some early results we have obtained in dealing with integrated digital media, including motion video, with off-the-shelf components. Finally, we draw some conclusions about required support for digital media.
STREAMS is a prototype application designed and implemented at Bellcore to support the recording and playback of technical presentations, training sessions, and meetings. During playback STREAMS lets users make choices about how the recorded information is to be presented. To further aid users, STRBAMS incorporates powerful searching techniques for locating information in audio and video streams.STREAMS is based on digital storage of multiple streams. A stream is typically an audio track or a (silent) video track. Streams are stored independently, but share a common dimension -time. This common dimension is used to synchronize the streams during playback, browsing, and searching.The driving paradigm of STREAMS is to empower the user to make intelligent choices. STREAMS lets the user (implicitly) allocate resources by controlling playback. For example, the user can turn off playback of a video stream, increase the quality of the audio, or decrease the frame size of another video stream. STREAMS also empowers the user
