Abstract
According to various embodiments of the present disclosure, there is provided a method of operating a source device. The method includes receiving a hot plug detection (HPD) signal from a sink device; receiving extended display identification (EDID) and DisplayID from the sink device; determining an adaptive-Sync data block and a frame rate based on the EDID and the DisplayID of the sink device; and transmitting a session description protocol (SDP) generated based on the determined adaptive-Sync data block, and information of the determined frame rate to the sink device.
Claims15
A method of operating a source device, the method comprising:
- receiving a hot plug detection (HPD) signal from a sink device;
- receiving first information related to an extended display identification (EDID) or a Display ID (DPID) from the sink device;
- determining a specific video timing frame rate based on a plurality of video timing frame rates included in the first information of the sink device;
- based on an adaptive-Sync data block included in the first information being related to a plurality of adaptive-Sync frame ranges, determining a specific adaptive-Sync frame range, of which a maximum frame rate is related to the specific video timing frame rate, among the plurality of adaptive-Sync frame ranges;
- and
- transmitting processed information based on the specific adaptive-Sync frame range to the sink device.
A source device comprising:
- a processor;
- a memory;
- and
- a transceiver,
- wherein the memory stores instructions performing operations based on being executed by the processor,
- wherein the operations comprise:
- receiving a hot plug detection (HPD) signal from a sink device;
- receiving first information related to an extended display identification (EDID) or a DisplayID (DPID) from the sink device;
- determining a specific video timing frame rate based on a plurality of video timing frame rates included in the first information of the sink device;
- based on an adaptive-Sync data block included in the first information being related to a plurality of adaptive-Sync frame ranges, determining a specific adaptive-Sync frame range, of which a maximum frame rate is related to the specific video timing frame rate, among the plurality of adaptive-Sync frame ranges;
- and
- transmitting processed information based on the specific adaptive-Sync frame range to the sink device.
One or more non-transitory computer readable mediums storing one or more instructions,
- wherein the one or more instructions perform operations based on being executed by one or more processors,
- wherein the operations comprise:
- receiving a hot plug detection (HPD) signal from a sink device;
- receiving first information related to an extended display identification (EDID) or a DisplayID (DPID) from the sink device;
- determining a specific video timing frame rate based on a plurality of video timing frame rates included in the first information of the sink device;
- based on an adaptive-Sync data block included in the first information being related to a plurality of adaptive-Sync frame ranges, determining a specific adaptive-Sync frame range, of which a maximum frame rate is related to the specific video timing frame rate, among the plurality of adaptive-Sync frame ranges;
- and
- transmitting processed information based on the specific adaptive-Sync frame range to the sink device.
