Abstract

An embodiment of the present disclosure provides a data transmission method that transmits data in a clock-embedded manner, including: dividing the data into a plurality of data packets having a bit number of ‘a’; determining a transition code including information on a first transition facilitating data packet and a second transition facilitating data packet having the same high-order bits ([a−1:1]) among the data packets; converting the plurality of data packets into transition ensuring data packets by using the transition code; and transmitting the transition code and the transition ensuring data packets.

First claim

What is claimed is:

1. A data transmission method that transmits data in a clock-embedded manner, comprising:
dividing the data into a plurality of data packets each having a bit number of ‘a’, where ‘a’ is greater than one;
determining a transition code including information on a first transition facilitating data packet and a second transition facilitating data packet having the same high-order bit or bits ([a−1:1]) among the data packets;
converting the plurality of data packets into transition ensuring data packets by using the transition code; and
transmitting the transition code and the transition ensuring data packets.

2. The data transmission method of claim 1 , wherein:
when the bit number is ‘a’, the number of data values that is representable by the data is 2a.

3. The data transmission method of claim 1 , wherein:
the determining of the transition code further includes
grouping the data packets to include 2a−1-1 of the data packets per one transition code.

4. The data transmission method of claim 3 , wherein:
the first transition facilitating data packet and the second transition facilitating data packet are not included in a group of the data packet.

5. The data transmission method of claim 1 , wherein:
in the transition code, the least significant bit ([0]) is set as a complement of one of bits included in the high-order bit or bits ([a−1:1]).

6. The data transmission method of claim 1 , wherein:
the bit number ‘a’ is greater than two,
the converting of the plurality of data packets into the transition ensuring data packets includes:
in a case in which a data packet not including a transition among the plurality of data packets exists, converting the data packet into the first transition facilitating data packet when all bits of the data packet not including the transition are 0, and converting the data packet into the second transition facilitating data packet when all bits of the data packet not including the transition are 1.

7. The data transmission method of claim 6 , wherein
the data packet in which all the bits are 0 corresponds to data displaying a black grayscale, and the data packet in which all the bits are 1 corresponds to data displaying a white grayscale.

8. The data transmission method of claim 6 , wherein
the least significant bit ([0]) of the first transition facilitating data packet is 0, and the least significant bit ([0]) of the second transition facilitating data packet is 1.

9. The data transmission method of claim 6 , wherein
the converting of the plurality of data packets into the transition ensuring data packets includes
converting a data packet including a transition among the plurality of data packets into a transition ensuring data packet having the same value.

10. A data recovery method that recovers data transmitted in a clock-embedded manner, comprising:
as a method of recovering transition ensuring data to data packets,
receiving a transition code and the transition ensuring data packets; and
recovering the transition ensuring data packets to the data packets by using the transition code,
wherein the number of bits of each of the plurality of data packets is ‘a’, where ‘a’ is greater than one, and
wherein the transition code includes a first transition facilitating data packet and a second transition facilitating data packet having the same high-order bit or bits ([a−1:1]) among the data packets.

11. The data recovery method of claim 10 , wherein:
in the transition code, the least significant bit ([0]) is set as a complement of one of bits included in the high-order bit or bits ([a−1:1]).

12. The data recovery method of claim 10 , wherein:
the number of bits ‘a’ is greater than two,
the recovering of the transition ensuring data packets to the data packets includes:
comparing the transition ensuring data with the transition code;
converting the transition ensuring data into a data packet in which all bits thereof are 0, when the high-order bits ([a−1:1]) of the transition ensuring data is the same as the high-order bits ([a−1:1]) of the transition code and when the least significant bit ([0]) of the transition ensuring data is 0; and
converting the transition ensuring data into a data packet in which all bits thereof are 1, when the high-order bits ([a−1:1]) of the transition ensuring data is the same as the high-order bits ([a−1:1]) of the transition code and when the least significant bit ([0]) of the transition ensuring data is 1.

13. The data recovery method of claim 12 , wherein
the data packet in which all the bits are 0 corresponds to data displaying a black grayscale, and the data packet in which all the bits are 1 corresponds to data displaying a white grayscale.

14. The data recovery method of claim 12 , wherein
the recovering of the transition ensuring data packets to the data packets includes
converting the transition ensuring data packets into a data packet having the same value as the transition ensuring data when the high-order bits ([a−1:1]) of the transition ensuring data is not the same as the high-order bits ([a−1:1]) of the transition code.

15. The data recovery method of claim 10 , wherein
when the number of the bits is ‘a’, the number of data values that is representable by the data is 2a.

16. The data recovery method of claim 15 , wherein
in the receiving of the transition code and the transition ensuring data,
the transition code and the transition ensuring data are received in units of groups, and the group includes 2a−1-1 of the transition ensuring data per one transition code.

17. A transceiver comprising:
a transmitter including a transmission controller, at least one encoder connected to the transmission controller, and at least one transmitter unit connected to the at least one encoder, respectively; and
a receiver coupled in signal communication with the transmitter, the receiver including at least one receiver unit, at least one decoder connected to the at least one receiver unit, respectively, and a reception controller connected to the at least one decoder,
wherein the at least one encoder is configured to divide clock-embedded data into a plurality of data packets each having a bit number of ‘a’, where ‘a’ is greater than one, determine a transition code including information on a first transition facilitating data packet and a second transition facilitating data packet having the same high-order bit or bits ([a−1:1]) among the data packets, and convert the plurality of data packets into transition ensuring data packets by using the transition code.
