Due to such changes in the market environment of the broadcast contents, end users want to download broadcast contents such as TV dramas, which are broadcast in real time, in real time.

Since broadcast contents are distributed on a program-by-program basis, they are edited and distributed as a streaming file immediately after the broadcast program ends. Since the program is encoded, edited, and transmitted in this manner, broadcast contents can be produced only after the end of the broadcast program. Therefore, it took a long time to generate the broadcast program as a multi-quality streaming file immediately after the broadcast. For example, in the case of the 60-minute broadcast time, it takes about 30 minutes or more from the time immediately after the broadcast to the online distribution of the contents. Therefore, in order for the end user to download the broadcast contents such as the drama, it is inconvenient to wait at least 30 minutes immediately after the end of the broadcast.
