• Recording time of DR mode may vary
depending on the bit rate of broadcasting:
• High Definition (HD) quality: estimated bit rate
is 15 Mbps
• Standard Definition (SD) quality: estimated bit
rate is 8 Mbps
• Regarding recording time remaining:
Remaining time in the DR mode is calculated
with a bit rate of 15 Mbps. But the bit rate differs
depending on the broadcast, so the displayed
remaining time might be different from the actual
remaining time.
