¿µ¹®³»¿ë¿ä¾à | To define a new media format for multi-device control, we need to construct a metadata
structure containing device control information. The first phase is to design the commonly used metadata structure to every type of devices. The second phase is to define detail control parameters which are specific to each type of device. In this technical standard draft, we propose an efficient method to store this device control information in a existing media format by expanding MPEG-4 file format. The main idea of this proposal is that the device control information is one of the media stream such as audio stream or video stream. Fortunately, the MPEG-4 file system is well designed to include any type of media steam by specifying decoder specific information. Also the MPEG-4 file format has a hierarchical structure based on various information containers. In this standard draft, we explain the method to store device control information in the media format by extending MPEG-4 file system. |
