## Abstract

Disclosed are an apparatus and method for transmitting/receiving image data. The method for transmitting image data includes classifying each pixel of image data into upper bits and lower bits, enabling the classified upper bits to be included in a payload of a Most Significant Bit (MSB) packet, and also enabling the classified lower bits to be included in a payload of a Least Significant Bit (LSB) packet, generating a header of the MSB packet and a header of the LSB packet, combining the payload and the header to respectively generate the MSB packet and the LSB packet, and transmitting the generated MSB packet and the LSB packet.

## Claims

### Claim 1

A method for transmitting image data, the method comprising:
classifying each pixel of image data into upper bits and lower bits;
enabling the classified upper bits to be included in a payload of a Most Significant Bit (MSB) packet, and also enabling the classified lower bits to be included in a payload of a Least Significant Bit (LSB) packet;
generating a header of the MSB packet and a header of the LSB packet;
combining the payload and the header to respectively generate the MSB packet and the LSB packet; and
transmitting the generated MSB packet and the LSB packet.

### Claim 2 (depends on 1)

The method of claim 1, wherein the enabling of the classified upper bits inserts an error correction code into the upper bit to enable the classified upper bits to be included in the payload of the MSB packet.

### Claim 3 (depends on 1)

The method of claim 1, wherein the header of the MSB packet and the header of the LSB packet include error correction code type information, MSB/LSB classification information, information about a position on an image frame of image pixels included in the payload of each of the packets, and sequence information of an image frame.

### Claim 4

A method for receiving image data, the method comprising:
receiving a MSB packet or a LSB packet, and analyzing a header of each of the received packets to thereby ascertain information on image pixels included in the packet;
extracting upper bits from the MSB packet;
extracting lower bits from the LSB packet;
combining the upper bits and lower bits of a corresponding combination using the ascertained information about image pixels to thereby generate pixels; and
combining the generated pixels as image data and outputting.

### Claim 5 (depends on 4)

The method of claim 4, wherein the receiving ascertains error correction code type information, MSB/LSB classification information, information about a position on an image frame of image pixels included in the payload of each of the packets, and sequence information of an image frame.

### Claim 6 (depends on 4)

The method of claim 4, wherein the extracting of the upper bits decodes the error correction code to extract the upper bits when the error correction code is applied to the upper bits.

### Claim 7

An apparatus for transmitting image data, the apparatus comprising:
a bit classification unit to classify each pixel of image data into upper bits or lower bits;
a packet generating unit to generate a MSB packet including the upper bits and a LSB packet including the lower bits; and
a communication unit to transmit the generated MSB packet and LSB packet.

### Claim 8 (depends on 7)

The apparatus of claim 7, wherein the packet generating unit inserts, into a header of the MSB packet and a header of the LSB packet, error correction code type information, MSB/LSB classification information, information about a position on an image frame of image pixels included in the payload of each of the packets, and sequence information of the image frame.
