Abstract
According to the present disclosure, a method performed by a source device is provided. The method comprises: receiving, from a sink device, a Hot Plug Detection (HPD); receiving, from the sink device, an Extended Display Identification Data (EDID) and DisplayID; receiving, from the sink device, a first DisplayPort Configuration Data (DPCD) including first 1-bit information related to whether or not Adaptive-Sync 2.x is supported; transmitting, to the sink device, a second DPCD including second 1-bit information indicating that the Adaptive-Sync operation operates based on the DID2.x Adaptive-Sync Data Block; and transmitting, to the sink device, Video stream data and Adaptive Sync Secondary Data Packet (SDP).

A method performed by a source device, the method comprising:
- receiving, from a sink device, a Hot Plug Detection (HPD);
- receiving, from the sink device, an Extended Display Identification Data (EDID) and DisplayID;
- receiving, from the sink device, a first DisplayPort Configuration Data (DPCD) including first 1-bit information related to whether or not Adaptive-Sync 2.x is supported;
- transmitting, to the sink device, a second DPCD including second 1-bit information indicating that the Adaptive-Sync operation operates based on the DID2.x Adaptive-Sync Data Block;
- and
- transmitting, to the sink device, Video stream data and Adaptive Sync Secondary Data Packet (SDP).
A method performed by a sink device, the method comprising:
- transmitting, to the source device, a Hot Plug Detection (HPD);
- transmitting, to the source device, an Extended Display Identification Data (EDID) and DisplayID;
- transmitting, to the source device, a first DisplayPort Configuration Data (DPCD) first 1-bit information related to whether Adaptive-Sync 2.x is supported;
- receiving, from the source device, a second DPCD including second 1-bit information indicating that the Adaptive-Sync operation operates based on the DID2.x Adaptive-Sync Data Block;
- and
- receiving, from the source device, Video stream data and Adaptive Sync Secondary Data Packet (SDP).
A source device, the source device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory operably connected to the at least one processor,
- wherein the at least one memory is configured to store instructions that allow the at least one processor to perform operations based on being executed by the at least one processor,
- wherein the operations comprise:
- receiving, from the sink device, an Extended Display Identification Data (EDID) and DisplayID;
- receiving, from the sink device, a first DisplayPort Configuration Data (DPCD) including first 1-bit information related to whether or not Adaptive-Sync 2.x is supported;
- transmitting, to the sink device, a second DPCD including second 1-bit information indicating that the Adaptive-Sync operation operates based on the DID2.x Adaptive-Sync Data Block;
- and
- transmitting, to the sink device, Video stream data and Adaptive Sync Secondary Data Packet (SDP).
