Claim Text:
1. A video server apparatus configured to record contents data of a group of pictures (GOP) in a memory and to play back the contents data in response to a playback instruction, comprising: a table generator configured to generate a management table associating a first contents ID with the contents data, and to store the management table in the memory upon recording of the contents data, wherein the first contents ID corresponds to the contents data; a receiver configured to receive contents management information upon generation of a change request for the contents data, wherein the contents management information comprises information indicating the first contents ID to be changed, a change start position, a transfer start position, a transfer end position, a change end position, and a second contents ID corresponding to changed contents data, wherein the transfer start position and the transfer end position designate a required part when data before and after replacement positions are required to generate contents data at the change start position and the change end position in terms of a compression format; a decoder configured to decode contents data played back from the memory into a video signal; an encoder configured to re-encode the video signal with the contents data; and a controller configured to look up the management table based on the first contents ID and the second contents ID in the contents management information, to read, from the memory, contents data to be edited corresponding to a period from the transfer start position and the transfer end position, to edit the contents data recorded in the memory based on a look-up result of the management table, to control the decoder to decode the contents data to be edited into the video signal, to control the encoder to re-encode the video signal with the edited contents data, to record the edited contents data in the memory, and to update the contents data corresponding to the first contents ID in the management table after the editing with the contents data corresponding to the second contents ID, wherein the editing comprises at least one of an addition of a part of the contents data, a deletion of a part of the contents data, and a replacement of a part of the contents data.
