Title: INFORMATION DISTRIBUTION SYSTEM, MOBILE COMMUNICATION TERMINAL, AND INFORMATION DISTRIBUTION METHOD
Abstract:
Using a mobile station (10), a user sends a signal for requesting a broadcast station (70) to distribute music to a distribution management server (60). The request signal contains a tune ID on the tune that the user wants to be distributed and the address where the user wants it to be distributed. When the distribution management server (60) receives a request signal, if the tune is unpopular, the tune data and a decoding key to decode the tune data are sent to the mobile station (10) or an STB(40); however, if popular, only the decoding key is sent to the mobile station (10) or the STB (40). The mobile station (10) or the STB (40), if unpopular, decodes the tune data received from the distribution management server (60) with the decoding key; however, if popular, it receives the tune data through the broadcasting wave supplied from the broadcasting station (70) and decodes the tune data with the decoding key received from the distribution management server (60).
