Ensuring quality of service for image transmission: Hybrid loss protection
收藏 引用
IEEE TRANSACTIONS ON IMAGE PROCESSING 2004年 第6期13卷 751-757页
作者: Grangetto, M Magli, E Olmo, G Politecn Torino Dipartimento Elettron Ctr Multimedia Radio Commun CERCOM I-10129 Turin Italy
We present hybrid loss protection as a new channel coding and packetization scheme for image transmission over nonprioritized lossy packet networks. The scheme employs an interleaver-based structure, and attempts to m... 详细信息
