對於視訊串流傳輸越來越被渴望的情況下,許多的問題也浮現出來,同時有許多的方法被提出來解決這樣的問題。JSCC(Joint Source / Channel Coding)的概念,被廣泛的研究著。在這篇論文裡我們由龐大的實驗數據分析及長期研究這個問題的經驗,推論出一個相當簡潔的JSCC解決方法,對於任何頁框參照(frame-dependence)的壓縮影片,在任一網路情況均可立即求得一組JSCC的參數,包括GOP結構,頁框速率(frame rate),預先錯誤修正碼(FEC)的配置,此外我們的JSCC模組考慮到實用上的真實環境,引入了可適用於相異場景的頁框大小模組(frame size model),這是壓縮影像轉碼(source transcoding)常被忽略的。最後的模擬實驗都顯示出我們的JSCC模組可以適用於場景特性相異的數種影片,不論在一定範圍的封包遺失率下,或是不同的流量限制條件裡,我們的JSCC模組都可以達到相當接近於由全域最佳搜尋(brute-force search)的效能,甚至在包含變動封包遺失長度(burst loss length)的模擬環境裡,測試結果顯示我們方法的效能超越了全域最佳預測搜尋的結果,更重要的是,我們JSCC的時間複雜度遠低於全域最佳預測搜尋所耗費的時間成本。因此,對於在具有封包遺失特性的網路環境下,透過我們的JSCC模組的處理後可以讓使用者端得到較佳的畫框速率。
