(4) Playing time
The playing time on the DN-V750 depends on the capacity of the card and the playback bit rate. The DN-V755 has 40GB capacity.
Below is a description of basic methods for calculating the playing time and some examples.
2 Video + audio
Video playback bit rate (kbps) playing time (sec.) = capacity of video portion
Audio playback bit rate (kbps) playing time (sec.) 2 (2 channels, left and right) = capacity of audio portion
Capacity of video portion + capacity of audio portion = Total capacity (kbit)
Total capacity (kbit) 8 = Total capacity (kByte)
Total capacity (kByte) 1024 = Total capacity (required card capacity) (MByte)
2 Video only
Video playback bit rate (kbps) playing time (sec.) = capacity of video portion
Total capacity (kbit) 8 = Total capacity (kByte)
Total capacity (kByte) 1024 = Total capacity (required card capacity) (MByte)
2 Still images
Still image capacity per image (kbit) 8 = Total capacity (kByte)
Total capacity (kByte) 1024 = Total capacity (required card capacity) (MByte)
2 Audio only (MPEG1 Audio Layer 2)
Audio playback bit rate (kbps) playing time (sec.) 2 (2 channels, left and right) = Total capacity (kbit)
Total capacity (kbit) 8 = Total capacity (kByte)
Total capacity (kByte) 1024 = Total capacity (required card capacity) (MByte)
2 Audio only (16 bit Linear PCM)
16 (bits) sampling frequency (kHz) playing time (sec.) 2 (2 channels, left and right) = Total capacity (kbit)
Total capacity (kbit) 8 = Total capacity (kByte)
Total capacity (kByte) 1024 = Total capacity (required card capacity) (MByte)

[Calculations of required capacities - examples]
Depending on the encoder, capacities may be larger than the above.
In the LD compatible mode, there must be free space equal to the SPL00001.MPG playing time (seconds) x 1 kB, approximately.
