Problems solved by technology
However, in this prior art, content may be reproduced only based on lack of content, so there are problems in terms of security and commercialization of delivery services.
For example, it is possible for the user to play back at least part of the image or sound only based on lack of content, or to play back in an incomplete state such as a stuttering state
In this case, data distribution companies cannot charge appropriate fees or manage distribution data
