US 9,872,035 B2 · System and method for transcoding data

Abstract

A method for transcoding data comprises receiving an input stream of data formatted according to a USB standard, the input stream is partitioned into a sequence of blocks having a fixed length. At least one input block of the input stream comprises one or more data symbols and one or more control symbols, the one or more control symbols include one or more general control symbols. The method also includes transcoding the at least one input block to generate at least one output block comprising a synchronization block and a control/data block. The control/data block comprises the one or more data symbols of the at least one input block, a representation of the one or more general control symbols of the at least one input block, and a plurality of indicators indicating locations of the one or more data symbols and control symbols in the at least one input block.

Dependent claims

A method for transcoding data, the method comprising:

receiving, at a device, an input stream of data partitioned into a sequence of blocks having a fixed length number of symbols, the sequence of blocks including an input block comprising at least one data symbol and at least one control symbol;
responsive to the input block ending with a control sub-block having one or more consecutive control symbols, compressing the control sub-block of the one or more control symbols to generate a compressed control sub-block and appending an indicator to an end of the compressed control sub-block indicating whether remaining symbols of the input block outside the control sub-block include any additional control symbols;
responsive to the remaining symbols not including the additional control symbols, appending the remaining symbols of the input block outside the control sub-block to the compressed control sub-block with the appended indicator to generate a control/data;
and
outputting an output block including the control/data block.

An apparatus for transcoding data comprising:

a transceiver to receive an input stream of data partitioned into a sequence of blocks having a fixed length number of symbols, the sequence of blocks including an input block comprising at least one data symbol and at least one control symbol;
a transcoder to determine if the input block ends with a control sub-block having one or more consecutive control symbols, and responsive to the input block ending with the control sub-block, compressing the control sub-block of the one or more control symbols to generate a compressed control sub-block, appending an indicator to an end of the compressed control sub-block indicating whether remaining symbols of the input block outside the control sub-block include any additional control symbols, appending the remaining symbols of the input block outside the control sub-block to the compressed control sub-block with the appended indicator to generate a control/data block responsive to the remaining symbols not including the additional control symbols, and outputting an output block including the control/data block.

A non-transitory computer-readable storage medium storing instructions for transcoding data, the instructions when executed by a processor causing the processor to perform steps including:

receiving an input stream of data partitioned into a sequence of blocks having a fixed length number of symbols, the sequence of blocks including an input block comprising at least one data symbol and at least one control symbol;
responsive to the input block ending with a control sub-block having one or more consecutive control symbols, compressing the control sub-block of the one or more control symbols to generate a compressed control sub-block and appending an indicator to an end of the compressed control sub-block indicating whether remaining symbols of the input block outside the control sub-block include any additional control symbols;
responsive to the remaining symbols not including the additional control symbols, appending the remaining symbols of the input block outside the control sub-block to the compressed control sub-block with the appended indicator to generate a control/data;
and
outputting an output block including the control/data block.
