Can't help you with BitStream, but as for oversampling, see:

Wayne Schott, "Philips Oversampling System for Compact Disc Decoding," Audio,
April 1984, 32-35.

For a good general text, see:

Ken C. Pohlmann, Principles of Digital Audio, (Indianapolis, IN: Howard W. Sams
& Co., 1985). (There's a second edition out now.)

Pohlmann also wrote a good explanation of the MASH ("1-bit") D/A in his
"Insider Audio" column in Mix magazine a year or two ago.
