Ex) TR-2504 : Playback speed as below.

Playback

– 120/100 ips@ CIF, 2CIF, D1, 960H(NTSC/PAL)
– 120/100 ips@ HD(30p/25p)
– 120/100 ips@ FHD(30p/25p)
– 72ips@ 3MP, 60 ips@ 4MP, 40 ips@ 5MP

Recording per ch ips

– Recording below 2m. – 30ips.
– 3M recording ips : 18ips
– 4M recording ips : 15ips.
– 5M recording ips : 10ips.

FHD playback means that 30ips per second is played per channel when played on a four-division screen. (total = 30ips * 4 = 120ips)

Likewise, 3M is recorded 18ips per ch, so playback at full speed at 72ips when it is four-division screen.(4M at 60ips, 5M at 40ips)

For example, “4ch 1080p synchronous playback” means that 2M camera will be played at full speed on a four-division screen on a 4CH recorder.

(But, It’s not ‘Synchronous Playback’, if there are other interference during playback such as iRAS watch/search connection, clip copy etc)
