Patent 7482922 was granted and assigned to Sony on January, 2009 by the United States Patent and Trademark Office.
A movement made by a user viewing a television broadcast program, which is recorded on a hard disk device and read from the hard disk device to enable time shift viewing, is reproduced at a television (TV) set. The movement of the user is detected via a transmitting and receiving unit to which an electronic key card is held, and a reproduction position on a hard disk is recorded in a memory of a controlling apparatus main unit. A destination of the user is detected via a transmitting and receiving unit to which the electronic key card is held, and the broadcast signal is read from the stored reproduction position on the hard disk and then transferred to an electronic device at the destination. This enables a continuation of the broadcast program that was viewed to be viewed in a room at the destination.
