Abstract:
A videophone system includes a processor which selectively sets a television (TV) broadcast program viewing function mode and videophone function mode in response to manual operation of a remote control, a decoder which performs, in the TV program view mode, a TV program-use decode function for decoding a broadcast program signal received from a TV tuner to thereby display it on a display screen while producing audio sounds by loudspeakers and which performs, in the videophone function mode a videophone-use decode function for decoding a videophone signal received from a distant party to thereby display on the screen an image of the distant party using the screen and speakers, and an encoder which performs a videophone-use encode function for encoding a video signal from a camera and a voice signal from a microphone to generate a videophone signal, which is sent to the distant party via a network.
Abstract:
An information processing apparatus for realizing coexistence of a high-speed editing function for contents whose copyright is protected and a defending function for limitless movement due to alteration of the contents and a defending function for an illegal process using power-off. When the contents constructed on a block unit basis is received and division-edited, block unique information as unique information corresponding to each divided block is formed. Apparatus unique information to specify the apparatus is recorded into a memory or the like. A Hash value which is formed from the formed block unique information and the apparatus unique information which has previously been stored in the memory or the like is stored.
