Field Tests of Error-Resilient 3-D SPIHT vs. MPEG-2

摘要

Error Resilient and Error Concealment 3-D SPIHT (ETC-SPIHT) is a joint source channel coder developed to improve the overall performance against channel bit errors without requiring automatic-repeat-request (ARQ). The objective of this research is to test and validate the properties of two competing video compression algorithms in a wireless environment. The property focused on is error resiliency to the noise inherent in wireless data communication. ERC-SPIHT and MPEG-2 with forward error correction (FEC) are currently undergoing tests over a satellite communication link. The initial test indicates that ERC-SPIHT gives excellent results in noisy channel conditions is shown to have superior performance over MPEG-2 with FEC when communicated over a military satellite channel.
