Recenzii

"Experts from industry and academia overview current practices and future directions in the delivery of multiple media content over communications networks to users. Applications that incorporate multiple media types are specifically addressed, such as two-way, multipoint video conferencing and one-way streaming of video and audio. Chapters are descriptive in nature, focused on the presentation of results, insights, and key concepts, with a minimum of mathematical analyses and abstraction. Each chapter is intended to stand alone. Gibson is affiliated with the department of electrical engineering at Southern Methodist University." --Book News, Inc.®, Portland, OR
