近年來許多的網路視訊平台興起,如YouTube之類的網站,提供許多人將錄製的檔案放置在網路上讓其他的使用者觀看,但是這種架構無法提供使用者最即時的資訊與影片。在高速無線網路 IEEE 802.16成為熱門話題與應用的當下,透過這個傳輸環境提供立即性的視訊串流服務,讓使用者不需要等待影片上傳的時間。我們所設計的系統:全民衛星新聞採集在Personal SNG over Push-to-Watch System Architecture,讓使用者不僅可以馬上將錄製的影片提供給同樣使用這系統的其他使用者,而此平台的設計,也可以延伸到許多服務應用。
本文之目的為實行全民衛星新聞採集在Personal SNG over Push-to-Watch System Architecture技術中的串流上傳(Upstream)功能。即按即看(Push-to-Watch)系統主要提供即時串流播送分享,播報員(Reporter)透過個人行動裝置與無線網路技術,可將即時影像以串流傳輸與人分享。考量到播報員所使用的個人行動裝置性能不一,本文提出多重設定(Multiple Profiles)的串流上傳功能。隨著硬體性能跟網路傳輸狀況的不同,提供了可調適性的向前糾錯碼、自動重傳、非均等保護等功能供選用,以確保串流上傳的服務品質(Quality of Service)。最後,使用NS-2進行模擬實驗,驗證使用各種設定時的串流上傳的訊號品質。
In recent years there are many Internet video platforms, such as YouTube, allowed users to share their videos with others on the Internet, but they were unable to provide users with the most real-time information and videos. The IEEE 802.16 standard has become a hot topic. It provides the environment to transmit real-time video streaming, so users do not need to wait for the uploading time. The Personal SNG over Push-to-Watch System Architecture we proposed allowed users to share the videos they recorded with other users in the same system immediately. The platform is also able to provide many services.
The purpose of this paper is implementing the upstream function in the Personal SNG over Push-to-Watch System Architecture. Push-to-Watch system mainly provides the service of real-time streaming, so the reporters can upstream their real-time videos through their mobile devices and wireless network technology. The performance of the devices used by the reporters is different, so we propose the multiple profiles upstream function. We provide adaptive forward error correction codes, automatic repeat request, and unequal error protection for selection base on the hardware capability and the network states to ensure the quality of service. Finally, we use NS-2 as simulation tool to verify our algorithm.
