the tuned channel.

[Channel-dependent]

(hexadecimal format)

BFS Dir

The date and time (MMDD.hhmmss) 
that the BFS directory was last read.

[Time]

 0507.150027

Video

The program identifier (PID) number 
within the MPEG stream that contains 
the video information being decoded.



[Channel-dependent]



n/a: Tuned to an analog channel

Audio

The PID number within the MPEG 
stream that contains the audio 
information being decoded.



[Channel-dependent]



n/a: Tuned to an analog channel

that packets were transmitted out of 
order or with a gap between them,



0: No discontinuity errors



[Integer > 0]: Could indicate a 
problem

 If A/V Disc is high, an issue 

such as macroblocking may be 
present.
