Negotiation method and electronic apparatus used in ethernet channel of high definition multimedia interface

A negotiation method used in a high-definition multimedia interface, comprising:

• transmitting a first negotiation signal from a first side to a second side during a first specific time period for enabling negotiation of an Ethernet channel;
• and
• checking whether any negotiation signal transmitted from the second side is detected or not, for determining a result of the negotiation;
• wherein the first negotiation signal comprises a parameter of Energy Efficient Ethernet (EEE) or a parameter of Ethernet flow control.

An electronic apparatus used in a multimedia interface, comprising:

• a first side, for transmitting or receiving a multimedia signal;
• and
• a processing unit, coupled to the first side, for processing the multimedia signal;
• wherein the processing unit determines to transmit a first negotiation signal from the first side to a second side during a first/second specific time period for enabling a negotiation of an Ethernet channel when receiving any negotiation signal transmitted from another device at the second side;
• and, the processing unit determines to transmit a second negotiation signal from the first side to the second side during a third specific time period, and checks whether a negotiation signal sent from the second side is detected or not during the third specific time period for determining a result of the negotiation.
