A Generic Scheme for the Recording of Interactive Media Streams
نویسندگان
چکیده
Interactive media streams with real-time characteristics, such as those produced by shared whiteboards, distributed Java applets or shared VRML viewers, are rapidly gaining importance. Current solutions to the recording of interactive media streams are limited to one specific application (e.g. one specific shared whiteboard). In this paper we present a generic recording service that enables the recording and playback of this new class of media. To facilitate the generic recording we have defined a profile for the Real-Time Transport Protocol (RTP) that covers common aspects of the interactive media class in analogy to the profile for audio and video. Based on this profile we introduce a generalized recording service that enables the recording and playback of arbitrary inter-

The Recording of Interactive Media Streams Using a Common Framework1
The development of real-time transport protocols for the Internet has been a focus of research for several years. Meanwhile, the Real-Time Transport Protocol (RTP) is a well accepted standard that is widely deployed for the transmission of video and audio streams. The RTP specification, combined with a companion RTP profile, covers common aspects of real-time transmissions of video and audio in...
متن کاملA General Framework and Communication Protocol for the Real-Time Transmission of Interactive Media1
In this paper we present a general framework for the real-time transmission of interactive media, i.e. media involving user interaction. Examples of interactive media are shared whiteboards, Java animations and VRML worlds. By identifying and supporting the common aspects of this media class the framework allows the development of generic services for network sessions involving the transmission...
متن کاملA New Paradigm for the Recording of Shared Whiteboard Streams
The number of video conferences conducted over the Internet has constantly increased during the last years. The need to archive the multimedia data streams of the conferences became apparent, and a number of tools accomplishing this task for audio and video streams were developed. In many video conferencing scenarios, shared whiteboards are used in addition to audio and video to transmit slides...
متن کاملA Light-Weight Repair Protocol for the Loss-Free Recording of MBone Sessions
With the increasing popularity of MBone conferences, the need arose to archive the multimedia streams of these conferences. Like all network applications, a conference recorder is subject to packet loss, which introduces gaps into recorded media streams. Such gaps degrade the playback quality of an archived media stream or even disable the correct playback. In this paper, we present a novel sch...
متن کاملA Fast Publicly Verifiable Secret Sharing Scheme using Non-homogeneous Linear Recursions
A non-interactive (t,n)-publicly veriable secret sharing scheme (non-interactive (t,n)-PVSS scheme) is a (t,n)-secret sharing scheme in which anyone, not only the participants of the scheme, can verify the correctness of the produced shares without interacting with the dealer and participants. The (t,n)-PVSS schemes have found a lot of applications in cryptography because they are suitable for<...
