Hands-on instruments for the OTT courses. Each one opens real media and shows what is actually in it, rather than describing what should be.
Every coded picture in a segment on one vertical timeline: picture type, bit cost, decode and display time, and which other pictures each one predicts from. Reads a live HLS ladder or a purpose-built lab clip, and shows the difference between a closed GOP, an open GOP and a B pyramid as structure you can point at.
