A transport protocol that supports real-time communication of audio/video frames across campus-area packet switched networks is presented. It is a “best effort” protocol that attempts to ameliorate the effect of jitter, load variation, and packet loss, to provide low latency, synchronized audio and video communications. This goal is realized through four transport and display mechanisms, and a ...

Music publishers using the compact disc standard have introduced various copy protection schemes into the marketplace in the past several years, ostensibly in an effort to reduce sagging sales that the industry blames on illegal distribution of high-quality copies of compact discs. Over the course of three years, we performed a battery of tests against dozens of discs from various parts of the ...

Parameters of an immersive telepresence audio/visual system was first defined by a review of the literature and also a preliminary qualitative analysis with live subjects. The definition that emerged was drawn upon as criteria for the audio/visual design and equipment installation used for the present experiment. The definition is simulating a conferencing image of a person sitting on the other...

In this paper, we proposed to implement the Digital Audio Broadcasting-(DAB) Transmitter and receiver part. The main problem in frequency modulation is multipath fading and ISI. To solve this problem we proposed the use of DAB with OFDM system. A matlab-simulink model is designed for DAB. The well defined radio equipment designed to broadcast the radio stations provide high-class data and audio...

This paper describes a software architecture solution for rendering audio and haptic sensation. By most of existing 3D sound systems, it is difficult to generate appropriate sounds from virtual objects, depending on the material used and the location of the impact. We developed a method that we named AudioHaptics to generate audio and haptic sensation based on a physical model of the virtual ob...

Technology used in Digital TV has the potential to enhance the viewing experience for millions of hard of hearing people. The Clean Audio project commissioned by the Independent Television Commission (ITC), and continued by Ofcom, looks at methods by which the extra information contained in 5.1 surround sound broadcasts may be used to improve the intelligibility and enjoyment of television audi...

The safety of children has always been an important issue, and several studies have been conducted to determine the stress state of a child to ensure the safety. Audio signals and biological signals including heart rate are known to be effective for stress state detection. However, collecting those data requires specialized equipment, which is not appropriate for the constant monitoring of chil...

LED (Light Emitting Diode) lighting equipments can be redeveloped and employed to not only just illumination, but also can wirelessly send audio data for users. In order to make an LED bulb has two channels for stable lighting and high-quality communicates, we used LEDs with different wavelengths, which are visible light for illuminations (including dimming and toning) and infrared for data tra...

Purpose – The purpose of this paper is to describe developmental work with SMIL (Synchronized Multimedia Integration Language) to synchronize transcript captions with streaming audio. Design/methodology/approach – This paper provides an evaluation of the hardware/software required to digitally record oral histories and the methods developed at WSU to customize the presentation of streaming audi...

We have created a synchronous corpus of acoustic and 3D facial marker data from multiple speakers for adaptive audio-visual text-tospeech synthesis. The corpus contains data from one female and two male speakers and amounts to 223 Austrian German sentences each. In this paper, we first describe the recording process, using professional audio equipment and a marker-based 3D facial motion capturi...
