    摘要: A data storage and replay device uses measurements of the evolution of performance of the storage medium (typically a flash memory circuit) to predict an error rate of retrieval from a region of the storage medium. The prediction is used as a basis for dynamically selecting an ECC for encoding the data prior to storage of the data. The ECC is selected from a plurality of available ECC's so that a fastest encodable ECC is selected that is predicted to produce no more than a predetermined post-decoding error rate given the information. On decoding the data, which is typically audio or video data, is decoded and replayed at a predetermined speed. In another embodiment, the data stored using a plurality of ECC's together and an ECC is selected dynamically for decoding, so that an output data rate can be maximized or power consumption on replay can be minimized.

    摘要: Multiword information is encoded as based on multibit symbols in relative contiguity with respect to a medium, whilst providing wordwise interleaving and wordwise error protection code facilities. This may provide error locative clues across words of multiword groups, that originate in high protectivity clue words and point to low protectivity target words. The clue words may have a first uniform size and be interspersed in a first uniform manner. The target words may have a second uniform size and be interspersed in a second uniform manner. The organization may be applied for use with optical storage. Sectors may get provisional protectivity as a low-latency error correction mechanism.

The ECC is selected from a plurality of available ECC's so that a fastest encodable ECC is selected that is predicted to produce no more than a predetermined post-decoding error rate given said information. In this way the speed of transmission of data to the device can be maximized while keeping the error rate below an acceptable level in the predicted future after decoding. On decoding the data, which is typically audio or video data, is decoded and replayed at a predetermined speed. In another embodiment, the data stored using a plurality of ECC's together and an ECC is selected dynamically for decoding, so that an output data rate can be maximized or power consumption on replay can be minimized.
