Abstract
Likewise, delay and packet loss are two primary concerns for image transmissions. Existing approaches for delivering single-description coded images by TCP give superior quality but very long delays when the network is unreliable. To reduce delays, we have proposed to use UDP to deliver sender-receiver based multiple-description coded images. To further improve the trade-offs between delay and quality of either TCP delivery or UDP delivery, we have investigated a combined TCP/UDP delivery that can give shorter delay than pure TCP delivery and better quality than pure UDP delivery.
