That's a 'very bad' idea because it means using allocating extra
bandwidth for every channel -- so a channel's bitrate becomes the sum of
its core bitrate and combined additional bitrates of all subchannels,
severely crippling the amount of channels you can deliver. Statmuxing
won't 'fix' this (there will always be a minimum bitrate for all
subchannels that could be consumed at any time) -- let alone the issues
you will have with continuity in doing a seamless cross-channel switch.
Deliver the ads via low-bitrate trickled carousel w/erasure corrected
data reception. Tag the ads with metadata, and transmit triggers. Let
the box filter and splice. This has all been done before, why do people
keep going back to the ice ages...
Cheers
