摘要

当前的传输协议可能不适合通过无线信道传输实时压缩视频数据。这主要是因为通道的相对较高的误码率可能导致数据包损坏，而有限的带宽限制了通道编码的使用。损坏的数据包可能会被丢弃，使发送器假定正在发生拥塞。我们建议修改增强的普通文件传输协议(ETFTP)，以允许其用于MPEG-4无线视频传输，而不是开发一个全新的协议。此外，还描述了一种系统架构，其中应用层视频数据包封装在ETFTP数据包中，以便应用数据链路层信道编码。

Modification of ETFTP for MPEG-4 wireless video transport

Current transport protocols may not be suitable for streaming real-time compressed video data over a wireless channel. This is primarily true because the relatively high bit error rate of the channel can lead to packet corruption, while the limited bandwidth restricts the use of channel coding. Corrupted packets may be discarded, making the transmitter assume that congestion is occurring. Instead of developing a completely new protocol, we propose modifications to the enhanced trivial file transfer protocol (ETFTP) to allows its use for MPEG-4 wireless video transmission. Additionally, a systems architecture is described where the application layer video packets are encapsulated in ETFTP packets, so that data-link layer channel coding can be applied.
