Sony Dynamic Digital Sound - Reader

Reader

The SDDS reader is mounted on top of a 35mm projector. The film is threaded through the reader before it passes through the picture aperture. As the film runs, red LEDs are used to illuminate the SDDS soundtrack. CCDs (Charge-Coupled Devices) read the SDDS data and convert the stream of dots on the film into digital information. This information is pre-processed in the reader and passed on to the SDDS decoder.

Famous quotes containing the word reader:

    [I]f our reader should be neither informed nor amused, we shall be very sorry for his loss of time as well as our own.
    Sarah Fielding (1710–1768)

    The reader uses his eyes as well as or instead of his ears and is in every way encouraged to take a more abstract view of the language he sees. The written or printed sentence lends itself to structural analysis as the spoken does not because the reader’s eye can play back and forth over the words, giving him time to divide the sentence into visually appreciated parts and to reflect on the grammatical function.
    J. David Bolter (b. 1951)
