Sink apparatus, source apparatus, function block control system, sink apparatus control method, source apparatus control method and function block control method

A source apparatus comprising:

• a transceiver configured to receive specification information related to the sink apparatus and transmit contents;
• a control signal generator configured to generate a function block control signal related to the sink apparatus based on the received specification information and output properties of the content;
• and
• a controller configured to control the transceiver to transmit the generated function block control signal to the sink apparatus.

A method for controlling a sink apparatus, the method comprising:

• transmitting specification information related to the sink apparatus to a source apparatus;
• receiving content and a function block control signal;
• selectively turning on or off at least one function block among a plurality of function blocks of the sink apparatus according to the received function block control signal;
• and
• outputting the received content using at least one of the plurality of function blocks that remain on.

A method for controlling a source apparatus, the method comprising:

• analyzing specification information received from a sink apparatus;
• generating a function block control signal for the sink apparatus based on the analyzed specification information and output properties of the content;
• and
• transmitting the content and the generated function block control signal to the sink apparatus.

A method for controlling a function block, the method comprising:

• analyzing, by a source apparatus, specification information related to and from a sink apparatus;
• generating, by the source apparatus, a function block control signal for the sink apparatus based on the analyzed specification information and output properties of content;
• transmitting, by the source apparatus, the generated function block control signal and the content to the sink apparatus;
• and
• outputting, by the sink apparatus, the received content and selectively turning on or off at least one function block according to the received function block control signal.

A sink apparatus comprising:

• a plurality of function blocks configured to output content;
• a transceiver configured to receive a function block control signal that is based on specification information related to the sink apparatus and that contains at least an on/off command for at least one of the plurality of function blocks;
• and
• a controller configured to selectively turn on or off the at least one of the plurality of function blocks in response to the function block control signal.
