    Blu-ray players have been able to output 1080p video since their inception. [ citation needed ] Current Blu-ray players allow output of film-based material in conventional interlaced 1080i60 form. 1080p displays that are able to apply 3:2 pulldown reversal can deinterlace film-based content and achieve full 1080p image quality.

  8. Clock gating - Wikipedia

    At one end is the manual gating of clocks by software, where a driver enables or disables the various clocks used by a given idle controller. On the other end is automatic clock gating, where the hardware can be told to detect whether there is any work to do, and turn off a given clock if it is not needed.
