摘要 |
<p>A digital video recorder or player performs error correction coding and decoding in two separate or paged memories (156,158). During a first phase of operation, previously error-corrected or error-encoded data is read from a first memory (156) while simultaneously new data to be error-encoded or error-corrected is stored in the first memory (156). Meanwhile, the second memory (158) is used for error-encoding or error-decoding of previously-stored data. In the second phase, the memories reverse roles; the data stored in the first memory (156) is error-encoded or error-corrected while previously error-corrected or error-encoded data is read from the second memory (158) and replaced with new data to be error-encoded or error-corrected. These phases are performed in an alternating fashion throughout a record or playback operation.</p> |
