System and method for streaming video data

A server comprising:

• a communication circuit;
• a storage;
• at least one processor operatively connected to the communication circuit and the storage;
• and
• a memory operatively connected to the processor,
• wherein the storage stores a status value representing the transcoding state of video data, and
• wherein the memory includes instructions that when executed by the at least one processor, cause the server to:
• store video data uploaded to the storage without transcoding video data for a streaming service,
• receive a first request for streaming the video data from a first external device through the communication circuit, the first request including a identifier for identifying the video data,
• make a first determination regarding whether streaming data associated with the video data is available on the storage, based on the status value corresponding to the identifier included in the first request,
• transcode the video data for streaming, when the status value represents that the transcoding state of the video data corresponding to the identifier represents that the transcoding of the video data is not transcoded,
• store the transcoded video data in the storage,
• stream the transcoded video data, which is stored, to the first external device through the communication circuit,
• receive a second request for streaming the video data from a second external device through the communication circuit, the second request including the same identifier as the identifier included in the first request,
• make a second determination regarding whether the streaming data associated with the video data is available on the storage device, based on the status value corresponding to the identifier included in the second request, and
• stream pre-transcoded video data, which is stored, to the second external device through the communication circuit without further transcoding the video data, when the status value represents that the transcoding state of the video data corresponding to the identifier represents that the transcoding of the video data is in progress or completed.
