Abstract: A method and computer program product are provided to ensure a timely secure data erase by determining an erasure deadline for each physical volume of a plurality of physical volumes and calculating a remaining time for each physical volume. The remaining time is calculated for each physical volume by comparing a current date to the erasure deadline of each physical volume respectively. A secure data erase is performed on the plurality of physical volumes in an order based on the calculated remaining time, where the secure data erase is performed on the physical volume with a shortest calculated remaining time first.

Abstract: A recording control unit records program data for a second time period, from the time point the second time period before the lapse of a first time period from the start of recording, not only under a first title but also at a start portion of a second title. A combining unit identifies identical CM portions in the program data recorded redundantly under the first and second titles, connects the portion immediately preceding the start of the identified CM portion of the first title to the portion immediately succeeding the end of the identified CM portion of the second title, to form one title. An editing unit edits the program data to make shorter the length of the combined title, when the time of program data recorded under the combined title exceeds the first time period.

Abstract: A method of decoding a video signal is disclosed. The method includes decoding a bit stream of a base layer, obtaining flag information, obtaining information indicating an obtaining position of parameters. The parameters includes at least one of information on a phase shift of a chrominance signal and offset information. The method further includes obtaining the information on the phase shift of the chrominance signal based on the flag information and the information indicating the obtaining position of the parameters, and obtaining the offset information based on the flag information and the information indicating the obtaining position of the parameters. The method further includes up-sampling the picture of the base layer, and decoding a bit stream of an enhanced layer based on the reference picture up-sampled from the picture of the base layer, the information on the phase shift of the chrominance signal and the offset information.

Abstract: A networked personal video recording (“PVR”) system couples a plurality of clients to one or more PVR media servers over a network. One or more PVR media servers include television tuners to tune television signals. A storage medium buffers the television signals to implement PVR functionality. For example, the PVR media server records television programs for clients. Clients are assigned to television tuners, and the clients display television programs received at the assigned tuner. The network transfers the buffered television signals to the clients.
