Problem: The pits and lands themselves do not directly represent the zeros and ones of binary data. Instead, non-return-to-zero, inverted encoding is used: a change from pit to land or land to pit indicates a one, while no change indicates a series of zeros. There must be at least two and no more than ten zeros between each one, which is defined by the length of the pit. This in turn is decoded by reversing the eight-to-fourteen modulation used in mastering the disc, and then reversing the cross-interleaved ReedSolomon coding, finally revealing the raw data stored on the disc. These encoding techniques (defined in the Red Book) were originally designed for CD Digital Audio, but they later became a standard for almost all CD formats (such as CD-ROM).
How many ones are there between each zero?

GE would maintain 49% control of the new company, while Comcast owned 51%. Vivendi, which owns 20%, would have to sell its stake to GE. It was reported that under the current deal with GE that it would happen in November or December. It was also reported that Time Warner would be interested in placing a bid, until CEO Jeffrey L.
