Scalable coding investigation (AHG17) ([e-mail]) Investigate hooks that would be needed for support of bitstream scalability in HEVC syntax Study the applicability and effectiveness (e.g., relative to simulcast and single-layer coding) of scalability tools Study potential experimental conditions for evaluation of scalable video coding technologies	J. Boyce (chair), J. Kang, K. Minoo, W. Wan, Y.-K. Wang (vice chairs)

Resolution adaption (AHG18) ([e-mail]) Assess the complexity and efficiency of resolution adaption (as in JCTVC-F158) against alternative approaches e.g. increased QP, and pre-filtering. Study loss robustness properties and compare with techniques such as adaptive reference frame selection. Investigate suitable resolution switching filters. Consider the implications in terms of signalling, HRD, DPB management, and random access.	T. Davies (chair), P. Topiwala, P. Wu (vice chair)	N
