Abstract
A packet generating method in a wireless High Definition Multimedia Interface (HDMI) environment includes generating a packet which includes either AV data or control data in a payload and a field indicative of a packet type in a header according to a HDMI environment; and transmitting the generated packet. Accordingly, the AV data and the control data can be transceived over the single channel in the HDMI.
Claims12
A packet generating method comprising:
- generating a packet which comprises control data in a payload and a field indicative of a packet type in a header according to a High Definition Multimedia Interface (HDMI) environment;
- and
- transmitting wirelessly, the generated packet,
- wherein the control data in the payload comprises a field indicative of a type of control data,
- wherein the field indicative of the packet type in the header indicates Consumer Electronics Control (CEC) packet type and the control data is Consumer Electronics Control (CEC) data, and
- wherein the generating comprises generating control data, the control data comprising either a control command in the payload of the control data and a field indicative of the control data as the control data type in a header of the control data, or ACK data in response to a transmitted control data in the payload of the control data and a field indicative of the control data as the ACK data type in the header of the control data,
- wherein the generating the packet comprises generating an AV packet, and the AV packet and the control packet are transmitted over a single wireless channel.

A packet determining method comprising:
- receiving a packet;
- and
- determining, by an A/V device, whether the packet is an AV packet, and whether control data is in a payload according to a wireless HDMI environment by examining a field indicative of a packet type in a header of the packet,
- wherein the control data is Consumer Electronics Control (CEC) data,
- wherein the control data in the payload comprises a field indicative of a type of control data,
- wherein the field indicative of the packet type in the header indicates Consumer Electronics Control (CEC) packet type, and
- wherein the determining comprises determining control data, the control data comprising either a control command in the payload of the control data and a field indicative of the control data as the control data type in a header of the control data, or ACK data in response to a transmitted control data in the payload of the control data and a field indicative of the control data as the ACK data type in the header of the control data,
- wherein the AV packet and the control data are transmitted over a single wireless channel.
