Abstract
On a reception side, display processing and the like is easily performed in synchronization with content data. A cam coder transmits reproduction content data to a television set through a TMDS line of an HDMI cable. The cam coder transmits processing information used to perform the display processing in synchronization with the reproduction content data to the television set through a bidirectional communication path included in the cable before the reproduction content data is transmitted. Index information is added to the processing information for each unit of processing. Index information corresponding to the index information added to the processing information is added to the reproduction content data at a timing when the processing information of each unit of processing is processed. The television set superposes information on a shooting location, a date and time, and the like on an image in accordance with the processing information corresponding to the index information at a timing when the index information is added to the received content data.
