The present specification proposes a method for a source device receiving capability information of a sink device. More specifically, the method comprises the steps of: transmitting, to a sink device, a message requesting for the reading of capability information of the sink device; receiving, from the sink device, first capability information of the sink device; on the basis of a capability information version of the sink device which is readable by a source device, carrying out a version change procedure for changing the capability information version of the sink device; and, on the basis of the version change procedure, receiving second capability information of the sink device, wherein the version of the second capability information is a higher than the version of the first capability information.

Method for transmitting/receiving video data and device therefor

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).

Apparatus and method for performing an adaptive sync operation

A wireless power transmission apparatus for transmitting wireless power to a wireless power reception apparatus, according to an embodiment of the present specification: transmits wireless power to the wireless power reception apparatus by means of magnetic coupling to the wireless power reception apparatus at an operating frequency; communicates with the wireless power reception apparatus by using at least one of in-band communication using the operating frequency and out-band communication using BLUETOOTH® communication; performs an authentication step with the wireless power reception apparatus to increase the level of the wireless power being transmitted to the wireless power reception apparatus; and includes, in a BLUETOOTH® packet, an authentication message required in the authentication step, and transmits the included authentication message to the wireless power reception apparatus via the BLUETOOTH® communication.

Wireless power transmission apparatus and wireless power reception apparatus for transferring and receiving wireless power

The present disclosure provides a method for a source device to establish a connection with a sink device, and an apparatus related thereto. According to the present disclosure, a method for a source device to establish a connection with a sink device comprising: receiving, from the sink device, first capability information of the sink device related to a specific operation; transmitting, to the sink device, support version information on a version of capability information of the sink device readable by the source device; and receiving, from the sink device, second capability information of the sink device related to the specific operation based on the support version information, wherein a version of the second capability information is configured based on the support version information.
