Claim:
A method of transmitting video data input as stream data in real-time, comprising: a video encoding process step of encoding the video data by: 1) dividing the stream data at predetermined points in time into a plurality of time-continuous video data, each of the plurality of time-continuous video data being different from each other, 2) performing an encoding process on each of the time-continuous video data to generate a respective plurality of encoded video data that form partial video data and 3) sequentially outputting the partial video data; a video data transmitting step of sending the partial video data in real-time; a metadata generating step of generating respective metadata of each of the partial video data to provide partial video metadata; and a metadata transmitting step of sending the partial video metadata, wherein the metadata generating step includes a step of managing a plurality of the partial video metadata having a time-continuous relationship as whole video metadata and outputting the respective partial video metadata including, at least, an identifier of the partial video metadata, link information to preceding and succeeding partial video metadata having the time-continuous relationship and link information to the respective partial video data.
