Abstract:
A negotiation method used in a high definition multimedia interface (HDMI) is provided. The negotiation method includes: transmitting a first negotiation signal from a first side to a second side during a first specific time period for enabling negotiation of an HDMI Ethernet Channel (HEC); and checking whether any negotiation signal sent from the second side is received by the first side for determining a result of the negotiation. The first negotiation signal includes parameters of Energy Efficient Ethernet (EEE) or parameters of flow control at least. Any packet of the negotiation signal excludes a data field of Start Frame Delimiter (SFD), and therefore the packet can be applied for point-to-point transmission and compatible with the Physical layer.
