Abstract:
1. An information processing apparatus for executing content information transmission processing comprising: a central processing unit and memory; the memory comprising computer instructions for execution by the central processing unit containing: a hardware storage unit configured to store content that includes at least one of audio content and image content; a request processing unit on the information processing apparatus configured to receive a content data list request including a reproduction specification from a client configured to reproduce the content, and acquire an address URL(uniform resource locator) indicating whereabouts of the content stored in said hardware storage unit based on said content data list request; and a data conversion confirmation unit on the information processing apparatus configured to determine whether the content stored in said hardware storage unit matches the reproduction specification from the client, determine whether the stored content converts to match the reproduction specification by performing, at the information processing apparatus, a data conversion processing of the stored content and generate data conversion specifying information including a first identifier that identifies an original format of the content and a second identifier that identifies a content format according to the reproduction specification; said request processing unit is further configured to generate a content list including a first version entry corresponding to a first version of the content and a second version entry corresponding to a second version of the content, the first version of the content and the second version of the content each including the content in a different reproduction format, said request processing unit further configured to receive a selected URL (Uniform Resource Locators) of the first version of content or second version of content in the content list from the client, and returns the content specified by the URL to the client to be reproduced and displayed, said client including a data transceiver unit configured to transmit the content data list request to the information processing apparatus, receive the content list from the information processing apparatus, and sending selection of a URL from the first address information of the first version of content or the second address information of the second version of content from the content list; a control unit configured to generate a display information based on the content list received from said information processing apparatus by said data transceiver unit, and generate the display information indicating whether the content requires the data conversion processing at said information processing apparatus based on the first content version conversion identification information from the first version of the content and the second content version conversion identification information from the second version of the content; a display unit configured to display the display information generated by said control unit, and the content returned to client.
