Patent number: 11234053Abstract: A device may receive a request associated with adjusting the media output level of a sink device that is configured to output media content. The device may identify a source gain of a source device that is configured to provide the media content to the sink device, and a sink gain of the sink device. The device may identify a sink adjustment value for changing the sink gain based on the request for adjusting the media output level of the sink device, the source gain, and the sink gain. The device may transmit, to the sink device, a control signal to permit the sink gain to be changed based on the sink adjustment value. The media output level of the sink device is based on the source gain and the sink gain.Type: GrantFiled: February 12, 2020Date of Patent: January 25, 2022Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Woo Seok Kang, Doo Hyun Kim, Sang Kwon Na, Ki Won Yoo, Chul Woo Lee, Jin Joo Chung, Doo Chan Hwang
