m17319	MPEG-4 AVC conformance testing status report		Mickaël Raulet
	Points & Recommendations	Patches for collecting golden references for AVC FUs (14 FUs) are provided. Most FU-level conformance testing in ALGO-FU level is complete except a few FUs. OpenDF supports RVC-CAL and wider set of CAL constructs. OpenDF implementation does not report well where variable initializations are missing and where Lists are not initialized when you are trying to access them. [Recommendation] need to discuss how conformance is described in the document with Chris.
m17322	MPEG-4 SP conformance testing status report with Btype		Ihab Amer, Mariam Mostafa Saleh, Marco Mattavelli, Mickaël Raulet
	Points & Recommendations	‘Btype’ based conformance testing report. Btype is not currently supported in VTL. [Recommendation] This work has to be merged with ‘without BYPE’.
m17325	RVC Conformance testing for IQ/IDCT and intra prediction of MPEG-4 AVC		Chris Lee, He-Yuan Lin , Tsung-Yuan Huang, Jia-Wei Liang
	Points & Recommendations	We need to harmonize the format of conformance testing document.
m17343	RVC Conformance Testing Result on MPEG-4 SP and RSM Debugging Report		Hyungyu Kim, Minsoo Park, Sowon Kim, Euee S. Jang
	Points & Recommendations	Some functionalities such as RVLC are not implemented in RSM. Most conformance testing results are comparable to m17322.
