chase play
v. phr.— «The unit constantly records up to two hours of TV into a buffer memory, which allows you to pause and rewind live TV, but sadly you can’t retrospectively record programmes from the buffer. You can also start watching a programme before it has finished recording, or “chase play” in marketing speak.» —“Humax Foxsat-HDR Freesat PVR” by Danny Phillips TrustedReviews Jan. 15, 2009.
