  • Method, apparatus, and system for transmitting moving image data
    Patent number: 7130618
    Abstract: A method, apparatus and system for transmitting moving image data, in which various moving image data of existent media files are efficiently delivered to existent TV cellular phones in reproducible format. A media file storage stores media files created in arbitrary format for filing moving images. A storage stores codec information on voice/image data and the media files as intermediate formatted data. A media file controller multiplexes the intermediate formatted data to generate a bit stream of voice/image data based on the codec information on the voice/image data. The interface converter transmits the bit stream of voice/image data to a TV cellular phone.
