Abstract: A content recording apparatus includes an obtaining unit which obtains a content having a variable-length packet structure, an encrypter which generates encrypted data by encrypting the content, and a recorder which records the encrypted data in a block unit having a fixed length in a recording medium. The encrypted data includes an invalidated region unnecessary for reproduction of the content. The recorder records a size of the invalidated region in the recording medium.

Abstract: There is provided a reproduction device that outputs a video signal to a display device via predetermined communication, the video signal including a video having pictures and corresponding pieces of image characteristic information. The reproduction device includes: an obtaining unit that obtains a first time difference between a timing at which the display device displays one picture among the pictures and a timing used by the display device to display one of the pieces of image characteristic information corresponding to the one picture; an adjuster that adjusts at least one of a timing at which the pictures are outputted and a timing at which the pieces of image characteristic information are outputted to reduce the first time difference; and an output unit that outputs the pictures and the pieces of image characteristic information via the predetermined communication at the time adjusted by the adjuster.
