Someone asked me to explain to them how the electronic anti skip
function used in ****table and car CD players worked and while I knew it
involved buffering the audio, I got thoroughly confused when I tried to
figure out how to explain that in more detail.
Wikipedia gave me this for "Electronic Skip Protection":
*********
Technology
When the buffering circuitry is in operation, the compact disc is read
at a fixed read speed or CAV and the content is buffered (with optional
ADPCM compression) and fed to RAM within the player. The audio content
is read from RAM, optionally decompressed, and then sent to the
amplifier. When the disc reading is interrupted, the player momentarily
reads the data stored in RAM while the tracking circuitry finds the
passage prior to the interruption on the CD.
********
The word "prior" in the last sentence confuses me, I would have expected
it to say "after" there.
Could someone please give me a better explanation or a link to one?
Thanks guys,
Jeff
