Apparatus and method for editing isochronous information transmitted among various devices

摘要

An apparatus and method for editing isochronous communication data used for communication between various electronic devices. An editing procedure with high accuracy can be conducted without reading the system data of isochronous communication in a system having co-existing isochronous and asynchronous modes of communication for data transmission between the electronic devices. The editing procedure can also be conducted with high accuracy in a system in which an edit controlling device cannot recognize the frame boundary in the information signals. Furthermore, even if there are various time delays associated with the instruction reception and the instruction execution by an electronic device, the editing procedure can be conducted with high accuracy.
