Content distribution system, content distribution method, and client terminal |
摘要 |
The user of any one portable terminal sends a content information request including a user ID to a distribution server. In response, the distribution server distributes a stream data of content that can be used on the user's terminal. If the user of a first portable terminal intends to let a second portable terminal try out a certain content, the user sends to the distribution server the trial permission information including the user's own user ID, a content ID of the content of interest, and a digital signature. The distribution server authenticates the received information before distributing a streaming data of a trial-oriented content with the content ID and user ID attached to it as search keys. This allows the content that can be used on a given user terminal to be tried out on another user terminal without the latter user having recourse to the steps of searching for the content in question.
