Ethernet-based image transmitting/receiving system

An Ethernet-based image receiving device comprising:

• a physical (PHY) module configured to receive a packet comprising at least one multiplexed signal which has synchronization information and is obtained by multiplexing a digital signal comprising a luminance signal and a chrominance signal, via an Ethernet cable;
• a medium access control (MAC) module configured to extract the multiplexed signal from the packet;
• and
• a control unit configured to separate the luminance signal and the chrominance signal from the multiplexed signal, store the luminance signal and the chrominance signal, and output the luminance signal and the chrominance signal by synchronizing lines with each other based on the synchronization information.

An Ethernet-based image transmitting/receiving system comprising:

• a digital image transmitting device configured to transform an analog image signal received from an image sensor into a digital signal including a luminance signal and a chrominance signal, multiplex the luminance signal and the chrominance signal to generate a multiplexed signal having synchronization information, and generate and transmit a packet including at least one multiplexed signal;
• a digital image receiving device configured to receive the packet, extracts the multiplexed signal from the packet, separate the luminance signal and the chrominance signal from the multiplexed signal, store the luminance signal and the chrominance signal, and output the luminance signal and the chrominance signal by synchronizing lines with each other based on the synchronization information;
• and
• an Ethernet cable configured to connect the digital image transmitting device to the digital image receiving device and transmit the packet.
