DTS has no mention of 754kbps, as it is an odd conversion rate. So either DTS miscalculated and 1509 should be 1536 or full-bitrate is not quite 1.5Mbps. I know, trival, but still, it would be nice if there was some standard for it.
In DTS, 1509 and 754 are the pay-load bitrates for the audio, 1536 and 768 are their corresponding carrier data rates. Carrier=payload+'household'. 'Household' data contains no audio.
