A Cost-Effective Mobile Video Streaming with an Adaptive Control of Inter-packet Delays

摘要

In a recent VoD application, a stationary VoD server delivers video stream to a mobile device, particularly PDA, over wireless. Typically, the sending rate at the server is faster than the playback rate at the handheld device. Therefore, it can't receive streaming video as possible as the sending rate even if there is no congestion and extremely low BER over wireless. Our objective is to develop a simple cost effective rate control scheme using a buffer level at a mobile device. We classify the buffer at a mobile device into three distinct states depending on its level (occupancy). For each of these states a different rate control is to be applied.
