An audio output system comprising:
- a key device including a communication tag;
- a main device configured to store a first playlist and to output audio content related to the communication tag based on the first playlist;
- a server configured to store a second playlist and to manage the first playlist based on the second playlist;
- and
- a user device configured to update the second playlist by accessing the second playlist,
- wherein if the second playlist is updated, the server provides a playlist update message to the main device, and
- wherein the main device updates the first playlist by comparing the first playlist and the updated second playlist with each other.
An audio content output device comprising:
- a sensing module configured to extract identifier information by detecting a communication tag;
- a storage module configured to store first identifier information and a first playlist about the first identifier information;
- an output module configured to output audio content in accordance with the first playlist;
- and
- a processing module configured to update the first playlist in accordance with a playlist update message from a server,
- wherein the processing module is configured to:
- receive the playlist update message from the server,
- receive, from the server, a hash value of a second playlist stored in the server, and
- determine whether to perform an update procedure of the first playlist by comparing a hash value of the first playlist stored in the storage module with the received hash value of the second playlist.
