Electronic device and operation method thereof

An electronic apparatus comprising:

• a streamer to perform adaptive streaming to thereby allocate network bandwidth in a descending order of priority based on priorities related to multi-streams, respectively, and receive the multi-streams that include a first to N-th streams in the descending order of priority, respectively, N being a natural number equal to or greater than 2;
• performing the adaptive streaming in the receiving starting from a stream having a highest priority among the first to N-th streams based on the priorities related to the multi-streams, respectively;
• a display;
• a memory storing one or more instructions;
• and
• a processor configured to execute the one or more instructions stored in the memory, wherein the processor is configured to:
• by executing the one or more instructions, obtain multi-content corresponding to multi-streams received through the streamer and control the display such that the multi-content is output in a multi-view mode so that the multi-content corresponding to the multi-streams is respectively output to a plurality of partial screens,
• wherein the adaptive streaming comprises:
• predicting whether an underflow will occur in a buffer receiving a stream with a higher priority, among a plurality of buffers, and
• buffering the stream with the higher priority and during the buffering of the stream with the higher priority, simultaneously continuing the buffering of the multi-streams according to a next priority among the multi-streams based on no occurrence of an underflow being predicted in the buffer receiving the stream with the higher priority,
• wherein the buffering of the stream with the next priority among the priorities related to the multi-streams comprises:
• predicting a time point at which the buffering of the stream with the next priority among the priorities related to the multi-streams is to be completed;
• identifying a packet to be reproduced at the predicted time point among packets of the multi-streams;
• and
• performing buffering from a packet of the stream with the next priority among the priorities related to the multi-streams to be output in synchronization with the identified packet.
