Apparatus and method for controlling media output level

A sink device, which is configured to connect with a source device and output media associated with the source device, the sink device comprising:

• a memory configured to store at least one program;
• and
• a processor configured to execute the at least one program to:
• receive a user input for changing a media output level of the sink device;
• identify a source adjustment value for changing a source gain of the source device and a sink adjustment value for changing a sink gain of the sink device in response to the user input;
• transmit, to the source device, a first control signal that causes the source gain to be adjusted based on the source adjustment value;
• receive, from the source device, the media of which the source gain is adjusted based on the source adjustment value;
• and
• apply the sink adjustment value to the received media to permit the received media to be output in association with the media output level.

A device for controlling a media output level, the device comprising:

• a memory configured to store at least one program;
• and
• a processor configured to execute the at least one program to:
• receive media information from a source device that is connected to the device;
• identify a source adjustment value for adjusting a source gain of the received media information, and a sink adjustment value for adjusting a sink gain of a sink device that is connected to the device in response to a request for adjusting the media output level of the sink device;
• adjust the source gain of the media information based on the source adjustment value;
• transmit the media information, of which the source gain is adjusted based on the source adjustment value, to the sink device;
• and
• transmit, to the sink device, a control signal for requesting a sink gain to be adjusted based on the sink adjustment value,
• wherein the media output level of the sink device is adjusted based on a combination between the source gain and the sink gain.

A method, comprising:

• receiving, by a device, information associated with a requested media output level of media configured to be output by a sink device that is connected to the device;
• identifying, by the device, a sink gain associated with the sink device;
• identifying, by the device, a source gain associated with a source device that is connected to the device, and that is configured to provide the media to the sink device;
• identifying, by the device, a sink adjustment value based on the requested media output level, the sink gain, and the source gain;
• and
• causing, by the device, the sink gain to be adjusted by the sink adjustment value to permit the sink device to output the media in association with the requested media output level.
