摘要： A method for forwarding messages containing cryptographic keys from a conditional access system that controls a population of set-top boxes to an encryption renewal system. The method includes storing a fictitious address of a virtual set-top box; generating a message based on the fictitious address, the message containing a cryptographic key; and forwarding the message to the fictitious address of the virtual set-top box. The encryption renewal system has information regarding the virtual set-top box, and is the receipient of the message. In addition, the encryption renewal system is for controlling access to pre-encrypted content generated by an encryption device. The system includes software instructions for receiving a request to retrofit an entitlement control message that allows a home device to access pre-encrypted content; and software instructions for retrofitting the entitlement control message only after verifying that the pre-encrypted content was generated prior to or contemporaneous with an authorized timestamp.

摘要： Movie texture mapping is performed in which compressed textures CTEX-1 to CTEX-N are expanded to form expanded texture ETEX-1 to ETEX-N which are in turn mapped onto an object in a sequential manner. Movie texture mapping for the random replay is performed in which textures are mapped on the object OB1 in the order starting from ETEX-K, and also on the object OB2 in the order starting from ETEX-L. Movie texture mapping for the frame-decimation replay is performed in which mapping of the expanded texture ETEX-I is followed by mapping of the expanded texture ETEX (I+J) (when J≧2). The compressed movie texture data contains data used to designate storage locations of the compressed textures CTEX-1 to CTEX-N . The objects OB1 and OB2 can be arranged to overlap each other to represent an image having an increased area such as a flame image. Replay starting frames K and L may be randomly set, and the number of texture frames to be decimated (J−1) may be determined according to event occurrence or time passage.
