Abstract
A time-shifted video method has a real-time mode during which real-time video frames are delivered for display. In a time-shifted mode, time-shifted video frames are delivered for display. The time-shifted video frames are delayed relative to the real-time video frames. A real-time frame is paused during a transition from the real-time mode to the time-shifted mode.
Claims22
A time-shifted video method comprising
- in a real-time mode, delivering real-time video frames for display,
- in a time-shifted mode, delivering time-shifted video frames for display, the time-shifted video frames being delayed relative to the real-time video frames, and
- pausing a real-time frame in a transition from the real-time mode to the time-shifted mode.
Video apparatus comprising
- a port to receive an input video signal,
- a time-shifted processing path that stores compressed video frames based on the input video signal and delivers time-shifted stored video frames to an output,
- a real-time processing path that delivers real-time video to the output based on the input video signal, and
- control circuitry that controls transitions between the real-time video frames and the time-shifted video frames at the output.
