<p>A method for managing buffers in an apparatus adapted for writing program portions onto and reading the program portions from a digital program disk comprises the steps of: filling a first buffer with encoded program portions at a first bit rate; filling a second buffer with the encoded program portions; supplying the encoded program portions from the second buffer for decoding; and, establishing an initial complementary fullness of the first and second buffers using an excess bit rate capability of the apparatus related to the first bit rate. The first bit rate is a constant bit rate slower than one-half of a maximum bit rate of the apparatus. An apparatus for implementing the method comprises a controller for recording the program portions onto alternate segments of the track, for initiating complementary operation of record and track buffers and for maintaining the complementary operation.</p> |
