- if you are using MPEG-1 VCD format , 650 MBytes per hour are
used. So if you want a 1/2 hour buffer, then set the Limit Pause
Mode Buffer Size to 325 MBytes.
- if you are using MPEG-2 4.0MB/sec , about 2 Gigabytes per hour is
used for the Pause buffer. So for a 30 minute buffer, then set the
Limit Pause Mode Buffer Size to 1000 MBytes.
Delay counter:
The Delay counter displays how much time you are behind the live
video. For example, if the delay counter says 00:01:23, then the video
window is showing video 1 minute and 23 seconds behind live video.
Pause button:
Clicking the Pause button or OTP button causes WinTV to start saving
a audio and video stream (referred to as an A/V stream) into the WinTV's
Replay Buffer. It takes about 10 seconds for the Replay Buffer to be ini-
tialized and for Pause to become effective.
Unclicking the Pause button will cause the audio/video program to
start playing from the point where the button was originally pushed.
Most WinTV functions are active while in the Pause or Pause Live mode.
For example, you can change volume, resize the TV window, go into
"no-title mode" , etc.
While in Pause mode, the Video Position bar shows the amount of the
Replay Buffer which is filled with video. For example, if the Video
Position indicator shows halfway, it means that half of the Replay Buffer
is filled. If you find you cannot Replay or Pause as many minutes as you
would like, increase the size of the Replay Buffer.
While in Pause mode, the A/V stream is always saved in the Replay
Buffer. To stop saving the A/V stream in the Replay Buffer, you must exit
the Pause mode by clicking the TV mode button.
Replay button:
While in the Pause mode, hitting the Replay button acts like the Instant
Replay you see on TV broadcast sporting events: the audio/video goes
back in time and you repeat what you have previously seen.
Each click of the Replay button causes audio/video to go back 10 sec-
4-2
