Abstract: In a method for recording and displaying a script executed on an electronic device, the electronic device includes a camera, at least one processor, and a display device, the method including: start recording a video data of a script by the camera when receiving an operation command of recording; recording time information in the script; start recording a new video data of the script by the camera when detecting an interrupt request; stop recording the script when a stop command is detected; and publish the script to a preselected server.

Abstract: An apparatus and method are disclosed for detecting the velocity of a tape in a tape transport system having a write head and a read head separated by a known distance and formatting the tape using marks. The tape transport system generates a write signal indicating when one of the marks is written to the tape by the write head and a read signal indicating when one of the marks is read from the tape by the read head. An accumulator determines the amount of time between the write signal and the read signal. A velocity detector determines the velocity of the tape based on the time determined by the accumulator and the known distance between the write head and the read head.
