Abstract:
1. An information processing apparatus, comprising: a first receiver configured to receive a first packet group of first content to which a first copyright protection method is applied and which is output to a first transmission path, the first content comprising first image data for reproducing a first image of first resolution; a second receiver configured to receive a second packet group of second content to which the first copyright protection method or a second copyright protection method is applied and which is output to a second transmission path, the second content comprising difference data between second image data and the first image data, the difference data being used for generating the second image data with the first image data, the second image data being used for reproducing the first image as a second image of second resolution higher than the first resolution; a converting device configured to re-packetize the first content packetized into the first packet group received by the first receiver and the second content packetized into the second packet group received by the second receiver, into a third packet group for outputting to a transmission path by applying a third copyright protection method, wherein the converting device extracts a first PID (Packet Identification) from the first packet group and extracts a second PID from the second packet group, acquires first PAT (Program Association Table)/PMT (Program Map Table) from the first PID and acquires second PAT/PMT from the second PID, generates a third PMT for reproducing the second image based on the first PAT/PMT and the second PAT/PMT, and includes the generated third PMT in the third packet group; and an output device configured to output the third packet group of the first content and the second content generated by the converting device to a third transmission path.
