1. A video display apparatus that obtains content data from a video output apparatus using one of a plurality of transfer protocols and displays the obtained content data, comprising: a first obtaining unit that obtains, from the video output apparatus, information of content data, including information regarding at least a coding scheme; a first determination unit that determines whether the content data is decodable by the video display apparatus based on information regarding the coding scheme obtained by the first obtaining unit; a second determination unit that determines, when it has been determined by the first determination unit that the content data is decodable by the video display apparatus, whether format conversion of the content data is required to the video display apparatus; a determining unit that determines, when it has been determined by the first determination unit that the content data is not decodable by the video display apparatus, among the plurality of transfer protocols, a transfer protocol in which the content data is decoded at the video output apparatus and transferred by a stream transfer; and a request unit that specifies the transfer protocol determined by the determining unit and requests the video output apparatus for transfer of the content data, wherein when it has been determined by the second determination unit that the format conversion of the content data is required to the video display apparatus, the determining unit also determines, among the plurality of transfer protocols, a transfer protocol in which the content data is not decoded at the video output apparatus and transferred by a file transfer.
