专利汇可以提供Real time file builder专利检索,专利查询,专利分析的服务。并且A system and method for use as an authoring system for the development of CD-ROM products containing interleaved digitized audio and graphic images and other information which may be read and displayed or played under control of a computer. By use of the invention, the graphic images and other computer information are stored in a file on the CD-ROM such that when the CD-ROM is accessed by a user, the graphic images and other computer information are displayed and made available to the user synchronously with the playing of the audio information. Combinations of several streams of audio and graphic/computer information can be interleaved into the same file allowing the user, at run time, to choose which stream is to be viewed and which stream is to be listened to at any given time. The system enables an editor to combine various audio files in synchronization with multiple graphic images into a single file which can then be stored on a CD-ROM. Other computer information can also be interleaved with the graphics and audio to allow for control over the playback at runtime. The graphics and other computer information are referred to herein collectively as "resources." The system allows the temporal and spatial placement of the resources on a run time computer screen to be displayed at a time and position which is specified by the editor when authoring. In addition to providing an authoring system, the invention specifies an interleaved data format that meets two criteria. Firstly it works well with low bandwidth media and, in its current embodiment, is optimized for storage on CD-ROM. Secondly, the interleaved nature of the data structure permits buffered playback which delivers continuous audio synchronized with the display of graphic images. When the editor has determined that the authoring process is complete, the system allows for the building of a real time file. The real time file consists of packets of audio data interleaved with packets of graphics and other computer data.,下面是Real time file builder专利的具体信息内容。
