20090055414 | METHOD AND SYSTEM FOR FEEDBACK OF DECODED DATA CHARACTERISTICS TO A DECODER IN STORED DATA ACCESS AND DECODING OPERATIONS TO ASSIST IN ADDITIONAL DECODING OPERATIONS - Aspects of a method and system for feedback of decoded data characteristics to decoder in stored data access and decoding operations to assist in additional decoding operations are presented. Aspects of the system may include a decoder that enables decoding of a portion of encoded data. A processor may enable generation of at least one hypothesis based on the decoded portion of encoded data and/or redundancy information associated with at least the decoded portion of the encoded data. The decoder may enable generation of one or more subsequent portions of decoded data based on the generated at least one hypothesis. | 02-26-2009 |
20090067550 | METHOD AND SYSTEM FOR REDUNDANCY-BASED DECODING OF AUDIO CONTENT - Aspects of a method and system for redundancy-based decoding of audio content are provided. A redundancy parameter may be generated for verifying a decoded bit sequence that comprises audio content, such as a decoded audio frame. The redundancy parameter may be a cyclic redundancy check (CRC) value and/or a length of frame value associated with the decoded audio frame. Information associated with the redundancy parameter may be comprised within a header of the audio frame. For example, a length of frame value, a bitrate value, a sampling rate frequency value, and/or a frame padding value may be comprised within the header of the audio frame. If the verification of the decoded audio frame fails, subsequent decoding of the previously decoded audio frame may be performed by imposing at least one physical constraint that results from the encoding of the audio frame. | 03-12-2009 |
