PORTABLE MULTIMEDIA SERVICES USING A HARDWARE TRANSCODER

摘要

The present invention relates to a system for providing a multimedia service to a portable device. The multimedia service system of the present invention includes a multimedia source, a hardware transcoder, an interface unit, a storage unit and a portable device. The multimedia source provides multimedia contents including video and/or audio data. The hardware transcoder converts the multimedia contents into contents having a format suitable for a display device of the portable device. The interface unit transmits the contents converted by the transcoder. The storage unit stores therein the contents received through the interface unit. The portable device receives the contents from the storage unit and displays the contents. The transcoder changes at least one of video and/or audio formats, a bandwidth (data rate), a frame rate and a resolution of the contents provided from the multimedia source. Accordingly, the present invention can provide multimedia contents most suitable for a portable device having a relatively low display capability.
