Earlier small-dish satellite systems sort of worked around this by showing each I-block as it came in (something like , instead of waiting for the full frame to be available. You still had to wait for enough macroblocks to show up, but audio was instant. Later receivers (last time I used one a long time ago) waited for a full frame to be available instead of showing the blocks as they are displayable. I have been trying to look up what this I-frame-less encoding method is called, but it's impossible to find niche topics like this on Google or DDG these days (tried intra sweep, iframeless, progressive intra, without iframes, etc).
