- In this paper, we present an effective streaming method for MPEG-4 contents using the schedule information of image objects and progressive JPEG. The proposed method is designed for Interactive Scalable Multimedia Streaming (ISMuS) system. In rich interactive contents, the amount of image objects is not negligible for a streaming service with QoS. If a streaming system does not manage the image data, it could create a bottleneck in the system. The proposed method considers the schedule information of image objects to be displayed within a specific time frame, generally within a few second. Since the proposed method uses the progressive JPEG instead of Baseline JPEG, it treats image object as scalable Object. The streaming server sends surely DC data of each image object and AC data of image object is sent only when there is an enough room for AC data in network bandwidth. The priorities of audio and video elementary stream are also within the consideration as well as those image objects according to the varying network status.
