6.2.615148 Alc/flute conformance
Thank you. We’re not sure about the file extension, but also not sure what is best. The spreadsheet needs updating, and we need to find out how to handle a ‘large’ (12MB) conformance file. Then we can open an amendment to the conformance part. We’ll do that in Archamps, with all the other Corr.s and Amd.s.
6.3General consensus on the MPEG-2 TS approach 6.3.1What is a sequence?
multiple program, of which single is a special case
6.3.2Hint track overall
timescale recommended at 90kHz, or an integer division or multiple thereof.
6.3.3What is a sample? 6.3.3.1either multi-program, single TS packet per sample 6.3.3.2or single-program, multi TS packet per sample
In case (a), sync sample table is present but empty. Sample groups may be used to mark the sync points of the programs.
In case (b), samples that contain GOP boundaries should have a GOP boundary at the start of a sample. The sync sample table marks the samples which start GOPs, and if the sync sample table is absent, all the samples are at the start of GOPs. If the sync sample table is present but empty, the GOP positions are unknown and may be not at the start of samples.
Case (b) covers the (unusual) case of one sample for the sequence.
