This paper presents a bit-depth scalable coding solution that is compatible with the scalable extension of H.264/Advanced Video Coding (AVC), also referred to as scalable video coding (SVC). The proposed solution is capable of providing an 8-bit AVC main profile or high-profile base layer-coded bitstream multiplexed with a higher bit-depth-enhancement layer coded bitstream generated through macroblock level inter-layerbit-depthprediction. New decoding processes for inter-layerprediction are introduced to enable bit-depth scalability. Compatibility with other types of scalability in the SVC standard-temporal, spatial, and SNR scalability-is ensured. It also supports the single-loop decoding required in the SVC specification. Furthermore, it supports adaptive inter-layerprediction to determine whether or not the inter-layerbit-depthprediction shall be invoked. This solution is implemented on the basis of the SVC reference software Joint Scalable Video Model version 8.12. Experimental results are presented on 8-bit to 10-bitbit-depth scalability and also combined bit-depth and spatial scalability.
