利用藍牙實現行動裝置協同式串流影片播放

Implementation of Collaborative Video Streaming on Mobile Device by Using Bluetooth

指導教授 : 陳育威

摘要


目前為止,行動影片串流服務皆是透過3G/WiFi連至網路存取影片,而在行動影片服務上,使用者大多為各自使用行動裝置來觀賞多媒體影片,有些使用者也有可能因網路頻寬的限制而無法流暢的觀看影片。本研究中,提出一個新串流系統,且使用其傳輸機制,提供即時串流影片利用3G/WiFi透過HTTP下載,然後經由藍牙分享給附近相同興趣的使用者,進行影片同步觀賞。本系統建置一HTTP Live Streaming Server,使用者只需使用iPhone/iPad透過3G/WiFi存取網址,便可同時將影片傳輸給透過藍牙連接進來的所有節點進行瀏覽,創造一個協同式的影片即時串流播放環境,最後經由我們建置的即時環境測試,我們所提出的系統及其傳輸機制能夠達到影片播放的連續性,並改善Buffer需求空間,達到能源消耗的降低。

Nowadays, many users access the desired video services via 3G/WiFi by using their mobile devices. In this thesis, we propose a new streaming system to provide a live streaming video. People can use their iPhone/iPad to access the Web of an HTTP live streaming server. Nearby users can share the same video via Bluetooth to create a collaborative video streaming environment. Further, we also build a real-time environment test-bed to verify the performance of the proposed method. The experiment results show that the proposed method for live video keeps the continuous playback, low buffer requirement, and low energy consumption.
