 To guarantee quality of service (QoS), the requirements for video transmission such as delay and cell loss rate (CLR) are very stringent. These constraints are difficult to meet if high network utilization is desired. Dynamic bandwidth allocation is thus needed. Video traffic prediction can play an important role in dynamic bandwidth allocation and traffic management in high-speed networks. I...

A dynamic bandwidth allocation strategy to support variable bit rate (VBR) video traac is proposed. This strategy predicts the bandwidth requirements for future frames using adaptive linear prediction that minimizes the mean square error. The adaptive technique does not require any prior knowledge of the traac statistics, nor assume stationarity. Analyses using six one-half hour video traces in...

One of the stated aims of 3 Generation mobile communications systems is to provide enhanced multimedia services to the user. Such services will include an integration of video, high-quality audio and data services. This paper describes a real-time mobile video communications system which employs ETSI’s GPRS mobile packet system as a mobile access medium. Subjective performance tests are carried...

Music composition can be a challenge for many smallto medium-sized game companies, largely due to the expense and difficulty in creating original music for each level of a game. To address this, we developed a tool that automatically generates original music, by training a music generator on pieces whose style the game designer wishes to imitate. The generator then creates original music in tha...

In the perception of gaits, timing is everything; specifically, the relative timing of the individual motions in a gait, and when events occur periodically, as they do in a gait, then relative timing is equivalent to phase. The importance of phase in gaits appears in the medical, psychology, and computer vision literature. The video phase locked loop (vPLL) [3] is a novel system that perceives ...

Digital video offers an interesting source of control information for musical applications. A novel synthesis technique is introduced where digital video controls sound spectra in real time. Light intensity modulates the amplitudes of 32 harmonics in each of several synthesized “voices.” Problems addressed include how to map from video to sound, dealing with global variations in light level, de...

The VISION (Video Indexing for Searching Over Networks) digital video library system has been developed in our laboratory as a testbed for evaluating automatic and comprehensive mechanisms for video archive creation and content-based search, filtering and retrieval of video over local and wide area networks. In order to provide access to video footage within seconds of broadcast, we have develo...

Real-time video processing, such as rendering and/or encoding, is one of the most bandwidth demanding operation in audio-visual applications [1][2]. There have been many efforts at parallelizing video rendering and encoding architecture mainly for VLSI chip design [3][4][5][6][7][8][9][10][11][12][13] [14][15][16]. However, not a lot of research has been dedicated in the area of distributed com...

Increasing amounts of research are being dedicated to the representation of video sequences in terms of component parts which are rendered and composited according to scripting information. Representations chosen range from two-dimensional layers all the way through full three-dimensional databases. These types of representations show great promise for compression, interactivity, and post-produ...
