We extend a recently-proposed framework for the rate-distortion optimized transmission of packetized media. The original framework assumed that each packet has a single arrival deadline and that a packet is useless if it arrives after its deadline. In practice, however, packets may be associated with multiple deadlines. Examples include the case of compressed video that uses bi-directional prediction and the case of decoders that can recover from late packet arrivals through the accelerated retroactive decoding of the dependency chain. We extend the original framework to consider multiple deadlines. In our experimental results for the case of the accelerated retroactive decoding of late packets, the multiple-deadline formulation yields up to a 3.15 dB improvement in rate-distortion performance compared to the original, single-deadline formulation. The results indicate, furthermore, that accelerated retroactive decoding offers significant benefit only when coupled with a scheduler that considers multiple deadlines.
