  • Patent number: 9088374
    Abstract: When a user gets interested in some music he/she listens to somewhere, for example, in a coffee shop, the user records that music in a memory provided in a portable terminal. A processor reads the information recorded in the memory and performs a predetermined process on it. The resultant information is stored on a storage device. The information stored on the storage device is then transferred to a remote server via a communication device. The remote server searches the database for the title of the music corresponding to the received information and returns the results to the terminal. Thus, the user can easily get information about the title of the music.

  • Patent number: 8042192
    Abstract: The present invention relates to an information processing apparatus, an information processing method, a recording medium, and a program for importing and exporting a content with information missing controlled. A CPU extracts a sound track contained in the content in step S301, and converts a format of the extracted sound track into a format compatible with a memory stick in step S302. The CPU generates a predetermined file from data contained in the content and excluding the sound track in step S304. In step S306, the CPU attaches reference information of the sound track to the file. In step S307, the CPU controls the writing of the sound track in the converted format and the file to the memory stick. The present invention is applied to clients of a DRM system.
