[ The second data may be data adapted to provide the content of the presentation 110 to the viewer of the presentation 110 through the viewer's terminal 160-1. For example, the second data may be data adapted to provide the terminal 160-1 with an image of the presentation 110 included in the first data.

The processing unit 220 may generate the second data by extracting data from the first data. For example, the processing unit 220 may generate the second data by extracting data excluding the audio data of the video of the presentation 110 from the first data including the video of the presentation 110. [

Alternatively, the processing unit 220 may generate the second data by processing the first data according to the option application information received by the communication unit 210. In other words, the processing unit 220 can generate the second data by applying the option indicated by the option application information received by the communication unit 210 to the first data.

By applying the option selected by the user of the terminal 160-1 to the first data, the second data can be generated as data suitable for providing the contents of the presentation 160 to the terminal 160-1. For example, the second data may be an image having a format and / or resolution suitable for the terminal 160-1 and the second data may be transmitted at a transmission rate selected by the user of the terminal 160-1 To the terminal 160-1.

In step 345, the communication unit 210 may output the second data generated by the processing unit 22. [ The communication unit 210 may output the second data to the terminal 160-1.

The contents of the presentation 110 can be provided to the user of the terminal 160-1 who is the viewer of the presentation 110 by outputting the second data to the terminal 160-1.
