I'm really not sure about this one. I think I'm leaning towards decimal, but what I'd really like is input from someone familiar with this spec and programs that edit or display MPEG-TS metadata. > > * Ogg: "id" should contain the Name header, decoded from UTF-8, if it exists, otherwise it should be the stream > > serial number, formatted as a decimal number. > > "name" is compulsory in Ogg Skeleton and it's a more reliable > identifier, because the serial number can change when transcoding or > re-multiplexing.

What I'd like to see is for the "id" to be something that makes sense to people who are familiar with particular formats. For example, in Matroska, it looks like people would expect the ID to be formatted as a decimal number. It's not clear to me what people would expect for MPEG-TS. Maybe we should just start with, "Any ID which is a number (or number-ish, like PID) should be represented as a decimal number"?
