Playing Time - Denon DN-V1700 Mode D'emploi

(4) Playing time

The playing time on the DN-V1700 depends on the capacity of the card and the playback bit rate.
Below is a description of basic methods for calculating the playing time and some examples.
2 Video + audio
Video playback bit rate (kbps) x playing time (sec.) = capacity of video portion
Audio playback bit rate (kbps) x playing time (sec.) x 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) x playing time (sec.) = Total capacity (kbit)
Total capacity (kbit) ÷ 8 = Total capacity (kByte)
Total capacity (kByte) ÷ 1024 = Total capacity (required card capacity) (MByte)
2 Still pictures
Still pictures 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) x playing time (sec.) x 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) x sampling frequency (kHz) x playing time (sec.) x 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)

Formula
3 x 120 ÷ 8 = 45
8 x 120 ÷ 8 = 120
128 x 3600 x 2 ÷ 8 ÷ 1024 = 113
16 x 48 x 600 x 2 ÷ 8 ÷ 1024 = 225
100 x 500 ÷ 1024 = 49
100 x 500 ÷ 1024 + 128 x 3600 ÷ 8 ÷ 1024 = 162
