Abstract:
When a video output apparatus (100) is connected, a video display apparatus (200) obtains information of content data stored in the video output apparatus (100). Then, based on the obtained information, the video display apparatus (200) determines whether the content data is decodable with respect to itself. If it is not decodable, it requests the video output apparatus (100) to decode the content data before transferring the content data using a data transfer method specified. By doing this, an appropriate transfer protocol is selected automatically when transferring content data between the video display apparatus (200) and the video output apparatus (100).
