在复杂无线网络环境下实现高效、无差错的多媒体信息传输是移动网络中多媒体应用部署的关键。对PET方法进行扩展,创建不同长度的PET通道,形成多逻辑PET通道;将JPIP消息在通道上传输,在提供差错保护的同时实现图像渐进传送。
In mobile network, it is critical to transfer multi-media data efficiently and error-free in the error-prone wireless environment. This paper extended the PET scheme based on JPEG2000 stream character. It defined the multi-channels with different unit length. Transferred JPIP message in the extended PET layer with powerful error-correct feature. Meanwhile supported the transmission in progress.
