recording times
Depending on the content being recorded, the
recording time may become shorter than
indicated.
• Recording time may vary depending on the
bit rate of broadcasting:
- High Definition (HD) quality: estimated bit
rate is 8 Mbps
- Standard Definition (SD) quality: estimated
bit rate is 4 Mbps
• Regarding recording time remaining:
Remaining time is calculated with a bit rate of
8 Mbps. But the bit rate differs depending on
the broadcast, so the displayed remaining
time might be different from the actual
remaining time.
