The Model 2470 Time Delay can create any program delay from 20 seconds to more than 24 hours. Delay time can be set with single frame precision in a hours / minutes / seconds / frames / format through a Graphic User Interface. Very high image quality is achieved without motion artifacts, by encoding video as I-frame MPEG-2 in 4:2:2 Profile, Main Level, at a fixed rate of 30 Mb/sec. Models are available for NTSC at 525 @ 29.97, and PAL at 625 @ 25 Hz. Inputs and outputs are provided for both SDI and Composite video. The Model 2470 Time Delay can create any program delay from 20 seconds to more than 24 hours. Delay time can be set with single frame precision in a hours/ minutes/ seconds/ frames/ format through a Graphic User Interface. Four audio channels are accepted in either AES/EBU format, or as embedded audio in an SDI stream. Alternatively, two channels of +4 dBu balanced analog audio can be selected. XLR-3 connectors are provided on the rear panel. 360 Systems' Bit-for-Bit® data handling ensures correct playback of Dolby®-E and AC-3 data streams, allowing the transmission of surround-sound program content. Because The 2470 transports high-value program material, its design incorporates a four-drive, RAID-5 disk array, to enhance reliability in the event of drive failure. Drives are easily replaced from the front without removing the time delay from a rack. Power consumption is low, and forced-air cooling extends component life and reliability. Model 2470 captures alpha-numeric data from lines 11 through 22 in the vertical blanking interval, with complete freedom from errors. Active Format Description (video indexing) per SMPTE RP-186 is optionally available on PAL units. 360 Systems' 2470 Time Delay will maintain long-term single-frame accuracy when connected to a stable genlock reference. It is intended to operate without user intervention; stored settings are non volatile, and are recalled each time power is applied.
