MULTIPLE DESCRIPTION CODING FOR MOTION JPEG VIDEO TRANSMISSION IN UMTS

In this paper, we propose a multiple description video coding system for robust transmission of video signal. We split the video frames into odd and even frames, and encode each frame separately based on JPEG standard. We assume that each description is transmitted in through WCDMA physical layer that used in UMTS . The channel is simulated based on Gilbert/Elliot’s model. We compare the result in threes cases: Video is reconstructed using only one description; video is reconstructed using both descriptions and finally video is reconstructed based on both description, and we do error concealment as well. The video quality is reported based on average peak signal to noise ratio for all cases for video sequences. 多描述 編碼 的Motion JPEG 視頻傳輸 的 UMTS 摘要 在本文中, 我們提出了 視頻信號的 傳輸 強勁 的多 描述視頻編碼 系統 。 我們 分割視頻 幀 分成奇數 和 偶數幀, 並編碼 分別 基於 JPEG標準 每幀 。 我們假設 每個描述 是通過 在 UMTS WCDMA 使用的 物理層 傳輸 英寸 該頻道 是基於 吉爾伯特 / 埃利奧特的 模型來模擬 。 我們比較 三五成群的 情況下,結果 :視頻 僅使用一個 描述 重建 ; 視頻使用 重建 都 說明 ,最後 顯卡基於 兩個 描述 重建 ,而我們 做的 錯誤隱藏 為好。 視頻 質量是基於 平均 峰值信號 為 所有的情況下 對 視頻序列 信噪比 報告 。
