A method for transmitting a packet in a high definition base transmission, HDBaseT, system, the method comprising: receiving, at a transmission adaptor, data (S820) from a source device; characterized by : converting, by the transmission adaptor, the received data to the packet in order to transmit the packet to a reception adaptor through an HDBaseT network; and transmitting the packet (S860) to the reception adaptor, wherein the transmission adaptor, the source device, and the reception adaptor are HDBaseT entities of the HDBaseT system which provides a simultaneous transmission of multiple streams, a transmission of uncompressed data, and a power transmission through a single cable, wherein the multiple streams are transmitted uncompressed, wherein the packet includes a four level hierarchical identifier for identifying HDBaseT entities to which the packet is to be transmitted, and wherein the four level hierarchical identifier includes a device medium access control, MAC, address field for identifying a device management entity of an HDBaseT device, a port identifier field for identifying a port device associated with the HDBaseT device, an HDBaseT group, T group, identifier field for identifying a T group associated with the port device, and a type mask field for identifying one or more HDBaseT adaptors, T adaptors, associated with the T group. receiving, at a transmission adaptor, data (S820) from a source device; characterized by : converting, by the transmission adaptor, the received data to the packet in order to transmit the packet to a reception adaptor through an HDBaseT network; and transmitting the packet (S860) to the reception adaptor, wherein the transmission adaptor, the source device, and the reception adaptor are HDBaseT entities of the HDBaseT system which provides a simultaneous transmission of multiple streams, a transmission of uncompressed data, and a power transmission through a single cable, wherein the multiple streams are transmitted uncompressed, wherein the packet includes a four level hierarchical identifier for identifying HDBaseT entities to which the packet is to be transmitted, and wherein the four level hierarchical identifier includes a device medium access control, MAC, address field for identifying a device management entity of an HDBaseT device, a port identifier field for identifying a port device associated with the HDBaseT device, an HDBaseT group, T group, identifier field for identifying a T group associated with the port device, and a type mask field for identifying one or more HDBaseT adaptors, T adaptors, associated with the T group. converting, by the transmission adaptor, the received data to the packet in order to transmit the packet to a reception adaptor through an HDBaseT network; and transmitting the packet (S860) to the reception adaptor, wherein the transmission adaptor, the source device, and the reception adaptor are HDBaseT entities of the HDBaseT system which provides a simultaneous transmission of multiple streams, a transmission of uncompressed data, and a power transmission through a single cable, wherein the multiple streams are transmitted uncompressed, wherein the packet includes a four level hierarchical identifier for identifying HDBaseT entities to which the packet is to be transmitted, and wherein the four level hierarchical identifier includes a device medium access control, MAC, address field for identifying a device management entity of an HDBaseT device, a port identifier field for identifying a port device associated with the HDBaseT device, an HDBaseT group, T group, identifier field for identifying a T group associated with the port device, and a type mask field for identifying one or more HDBaseT adaptors, T adaptors, associated with the T group. <EOS>
