A method to efficiently encode an arbitrary video
summary with temporal scalability and dynamic Group of
Pictures (GOP) structures is proposed in this paper. The video
summary is encoded as the base layer of a Scalable Video Coding
(SVC) bitstream using a novel approach, which matches the summary
frames available in temporal segments onto corresponding
dynamic GOP structures. An algorithm is devised to compute
variable GOP sizes along with an efficient independent prediction
structure for the summary. The results show that the proposed
method can be used to encode arbitrary video summaries with
increased efficiency in the temporal base layer and negligible loss
of R-D performance in the whole scalable sequence.
