Claim:
1. An encoding system, comprising: a sync data adding apparatus to add sync data to an ancillary data space of a video signal; an encoding apparatus to generate a bitstream in which the sync data is added by encoding the video signal in which the synch data is added; and a multiplexing apparatus to synchronize a plurality of bitstreams based on the sync data included in the bitstream, and multiplexes the synchronized bitstreams, wherein the encoding apparatus identifies the sync data in the ancillary data space of the video signal, and adds the identified sync data to a user data syntax among syntaxes of the bitstream, and wherein the multiplexing apparatus determines an interval for verifying the sync data based on the user data syntax added with the sync data, and synchronizes the plurality of bitstreams by verifying the sync data at the determined intervals.
