Devices and system for exchange of digital high-fidelity audio and voice through a wireless link

A system for communicating source data from a data source over a communications link, comprising at least one listener device including:

• a receiver receiving an encoded data block transmitted over the communication link, the encoded data block being formed by
• organizing a selected portion of source data into a data block having rows and columns;
• forming an encoded column from each column of the data block by appending column error-correction data for the column to the column, the column error-correction data being formed for each column by using a Reed-Solomon code to form the column error-correction data;
• forming an encoded row from each row of the data block and from each row of column error-correction data by appending row error-correction data for the row to the row, the row error-correction data being formed for each row by using a BCH-type code to form the row error-correction data;
• and
• transmitting each encoded row and a first predetermined number of rows of column error-correction data of the data block over the communication link, the first predetermined number of rows being less than a total number of rows formed by column error-correction data;
• and
• a transmitter transmitting a request for a second predetermined number of rows of column error-correction data to be transmitted when a number of errors contained in the transmitted encoded rows and the first predetermined number of rows of column error-correction data exceeds an error correction capability of the transmitted row error-correction data and the predetermined number of rows of column error-correction data, the second predetermined number of rows of column error-correction data being selected from the rows of column error-correction data that were not transmitted with the encoded rows corresponding to the second predetermined number of rows of column error-correction data.

A method of communicating source data from a data source over a communications link, the method comprising:

• organizing a selected portion of source data into a data block having rows and columns;
• forming an encoded column from each column of the data block by appending column error-correction data for the column to the column, the column error-correction data being formed for each column by using a Reed-Solomon code to form the column error-correction data;
• forming an encoded row from each row of the data block and from each row of column error-correction data by appending row error-correction data for the row to the row, the row error-correction data being formed for each row by using a BCH-type code to form the row error-correction data;
• and
• transmitting from a source device each encoded row and a first predetermined number of rows of column error-correction data of the data block over the communication link, the first predetermined number of rows being less than a total number of rows formed by column error-correction data.
