1. A communication device that receives, from a different communication device, video data that is encoded in a scalable manner, decodes received video data, and reproduces and outputs decoded video data, the communication device comprising:
a subjective-quality information acquiring unit that acquires subjective quality information in which a combination of values of multiple items related to a coding setting of video data is related to an evaluation result of a subjective quality with regard to video data; a determining unit that determines levels of priority of the items in accordance with at least any one of a purpose of video data that is received from a different communication device and a user's setting operation; a generating unit that generates coding setting information for determining a coding setting of video data that is received from a different communication device in accordance with the subjective quality information and the levels of priority of the items; and a notifying unit that notifies the coding setting information to a different communication device that is a transmission source of the video data.
