Abstract
A data error detection and mitigation system has been provided with a tiered approach. A set of received (104) data frames, which are ordered, are divided (106) into multiple groups, wherein at least one of the groups includes at least two nonconsecutive data frames. With these multiple groups, a data error check is inserted (108) for at least one of these groups. The data frames can relate to various types of information, such as audio, speech, video, images, files, or any data format with substantial similarity between successive frames.
Claims18
A method of detecting data error comprising:
- receiving data divided into a plurality of ordered data frames;
- dividing the ordered data frames into multiple groups, wherein at least one of the multiple groups comprises at least two nonconsecutive data frames;
- inserting a data error check in at least one of the multiple groups.
A method of detecting speech data error comprising:
- receiving a plurality of data packets, wherein each data packet includes multiple ordered speech frames;
- dividing the multiple ordered speech frames into a plurality of groups, wherein at least one of the plurality of groups comprises at least two nonconsecutive data frames;
- inserting a data error check in at least one of the multiple groups.
An apparatus comprising:
- an input having a plurality of ordered data frames;
- an error detection device coupled to the input that divides the ordered data frames into multiple groups and inserts a data error check in at least one of the multiple groups, wherein at least one of the multiple groups comprises at least two nonconsecutive data frames.
