Method of transporting data with embedded clock

A method for coding/decoding packet data, adapted to data packet processing in a data transmission interface, and comprising:

• determining a first bit length and a second bit length in an initial stage;
• obtaining original data of N bits to form a packet, wherein N is an integer of at least 4;
• analyzing whether a long-run length of long-run data with consecutive same bit data in the packet is greater than N/2;
• and
• coding the packet to embed clock/toggle information with the first bit length into the packet, wherein the clock/toggle information determines whether the long-run data is toggled,
• wherein an appearance frequency of the clock/toggle information serves as clock information,
• wherein when the long-run length is not greater than N/2, the long-run data is not toggled,
• wherein when the long-run length is greater than N/2, bit data with the second bit length after an Lth bit of the long-run data is toggled.

A method for transporting data with embedded clock, which is adapted to a data transmission interface, and comprising:

• receiving original data;
• packing the original data, wherein every N bits form a packet, and N is an integer of at least 4;
• dividing the N bits of each of the packets into a plurality of segments of data;
• inserting a coding index between each two adjacent segments of data;
• wherein the coding index is used to break consecutive same bits of the two adjacent segments of data that exceed a length of one segment of data;
• wherein the multiple segments of data is further divided into a plurality of groups of data, wherein at least one group of data applies a data toggle method for coding, wherein the data toggle method is to toggle data value of a rear half of the data when a length of the consecutive same bits is greater than a half of a length of the at least one group of data.
