  • Digital disk recorder using a port clock having parallel tracks along a timeline with each track representing an independently accessible media stream
    Patent number: 5642497
    Abstract: An application programming interface for a digital disk recorder uses a port to link resources together to form a multimedia recorder that emulates a tape recorder while retaining the flexibility of the digital disk recorder. The port is a matrix of timelines for each resource, with each track in the port representing a media stream associated with a different one of the resources. A dynamic subsystem controls recording and playing back multimedia between the resources and a disk file system of the digital disk recorder using the port. A static subsystem maintains on the disk file system a database of movies recorded by the digital disk recorder from the resources according to the port, with each movie being a collection of media files for each resource that are independently accessible.
