PROBLEM TO BE SOLVED: To provide a content receiving terminal for writing out (exporting) the video content to a recording medium, and capable of allowing other video reproduction terminals not to reproduce an export non-completed video content, when export processing is interrupted abnormally by power failure etc. at the content receiving terminal. SOLUTION: During export processing of a video content (S107), the content receiving terminal lets an encryption key for the content stored in the recording medium exist in the content receiving terminal (S103, S105, S106). Only when the export processing is completed or when interruption processing is performed normally for the export processing, the content receiving terminal writes the encryption key for the content in the recording medium (S111, S112). When the export processing is interrupted abnormally, other video reproduction terminals cannot reproduce the export non-completed video content, since the encryption key for the content is not stored in the recording medium.
