In the case of low bit-rate video streaming over wireless channels, burst channel errors possibly cause consecutive frame losses. Considering the source-channel characteristics of the specific case, this paper presents a novel error-resilience packet scheduling scheme based on the reference frame selection (RFS) without back-channel, which is called RFS-based packet scheduling (RFS-PS). By applying the delayed packet scheduling scheme in a group-of-picture (GOP) according to different delay requirements, the probability of simultaneous losses between different prediction chains can be reduced. Simulation results show that the proposed RFS-PS scheme can spread out burst packet losses into different chains, and effectively increase error resilience of low bit-rate video streaming over wireless channels
