  • Patent number: 8695049
    Abstract: The content switching apparatus includes at least a position identifying unit (800) and a play control unit (700). In switching from a first content (broadcast program) to a second content (VOD content), the position identifying unit identifies the position of the image in the second content, the image being the same as the first image of the first content. The play control unit determines a play starting position in the second content based on the position identified by the position identifying unit. By determining the play starting position of the second content in this way, the image can be properly switched even in the case where the time length or the content configuration is different.

  • Patent number: 8316403
    Abstract: In the case where the receiving apparatus 1 obtains, from a content archive, and reproduces a first video content having the same content as a program being broadcast, the difference of the ending time between the first video content being played and the program being broadcast is detected (S701). In the case where there is a difference in the ending time (YES in step S702), the receiving apparatus 1 obtains, from the content archive, a second video content having the same content as the next program started following the program being broadcast (S703, S704), and reproduces the second video content following the first video content being played (S705 to S709).
