隨著3G和4G無線寬帶接取(Wireless Broadband Access , WBA)技術和可延展性視訊編碼技術,如H.264/MPEG4進階視訊編碼(Advanced Video Coding -AVC)的發展下,使得無線通訊系統可以提供大範圍的無線視訊多播(multicast)及視訊廣播(broadcast)的服務,如行動網路協議電視(mobile IPTV)和無線數位電子看板(wireless digital signage)等相關性服務。然而目前的視訊通訊系統一般來說都需要一個低錯誤率且頻寬大的環境,因此要如何有效率的使用頻寬並且提升視訊在傳輸中的正確性是目前的研究話題。在本論文中,我們以基於交織多工(interleave division multiplexing , IDM)的編碼調變系統來實現傳輸多媒體視訊的疊加編碼調變系統架構,在接收機使用迭代偵測與解碼的方式還原多媒體影像資料,並且我們會分析迭代技術對影像還原後的效能;由於在現實通訊環境中頻寬是有限的,所以為了更有效率的使用頻寬,近幾年來許多重要的期刊論文都相繼提出不相等錯誤保護(Unequal Error Protection, UEP)技術的傳輸方法。在本論文中我們主要使多媒體資訊經過視訊壓縮編碼後產生不同重要性的資料並且將其資料依照重要性由SCM系統中不同的層做傳輸,並且將重要性較高的等級資訊分配較高的功率,將重要性次等的資訊分配較低的功率,藉此達到分層不相等錯誤保護的目的以提升整體的影像品質。
Advancements in 3G and 4G Wireless Broadband Access (WBA) technologies based on WiMax and 3GPP-LTE standards, as well as the scalable video coding technologies, such as H.264/MPEG4 Advanced Video Coding (AVC), have enabled the provisioning of large-scale wireless video multicast and broadcast services, such as mobile Internet Protocol Television (IPTV) and wireless digital signage. However, video communication systems generally require a low bit error rate and large bandwidth of the communication environment and therefore how effective the use of bandwidth as well as how to enhance the quality of the video transmission is a topic of current research. In this study, we based on a interleave division multiplexing (IDM) coded modulation scheme to achieve superposition coded modulation for multimedia transmission, and Receiver used the iterative detection and decoding methods to recovery the multimedia data as well as we will analyze the performance that utilize iterative techniques to recovery video data . However, the bandwidth is limited in the communication environment; recently many researches considered using unequal error protection (UEP) transmission scheme to have efficient use of bandwidth. In this study, we considering that multimedia stream encoded by H.264/AVC which will produced data with different importance and we transmitting the different importance data by different layers of SCM system, and then we utilize layer-wire UEP scheme which allocating higher-power to the high importance data layers and a lower-power to the low importance data layers, in order to enhance the overall video quality.
