Editing system, editing controlling apparatus, and editing controlling method

摘要

A splicer/transcoder device that interfaces with a material archiver/server using a stream. The splicer/transcoder device interfaces with an editor and switcher using a base band signal. In a predetermined region including at least an edit point, a transcoding process is performed. In an input stream, two programs to be edited have been multiplexed. The editor and switcher receives base band signals Sa and Sb of which respective programs have been encoded. As with a conventional editing device, the editor and switcher edits the base band signals and returns the edited result as a base band signal Sc to the splicer/transcoder device. The splicer/transcoder device re-encodes the base band signal Sc into an output stream using codec information obtained in the decoding process.
