MAXX-2470HD BROADCAST TIME DELAY Operations Manual
●Introduction
■360 Systems 2470-HD Time Delay is a high-quality program delay for television broadcast, satellite delivery, and other applications requiring a user-settable delay time for video, audio, and ancillary data. Applications for the delay include:
▲Compensation for time zone differences, where a program is received at a different time than when it needs to air.
▲Program origination delays, where content is time-shifted prior to transmission or distribution.
▲“+1” channels that allow cable casters to offer multiple feeds of the same program content to maximize channel exposure with limited additional cost. Viewers can choose to see a variety of different shows in their chosen viewing time, or see an immediate repeat of a show that interested them simply by changing the channel.
▲The 2570-HD-EX model can be used in a disaster recovery system where a 24 hour delay provides a guarantee of airing appropriate content for the time of day.
■The can be thought of as a black box that records video, audio, and specific ancillary data information; it then delays the playback of the program by a user-selectable time period. Whatever goes in, comes out later.
■The Time Delay will operate as a set-and-forget box with no user intervention. On restarting after a power failure, it will again start delaying the input according to the most recent user settings. The delay time is user-programmable from 6 seconds to greater than 24 hours. The programmed delay interval is frame-accurate over an indefinite time period; if several Time Delays are fed identical input signals, they will remain in sync indefinitely.
■The Time Delay employs high quality, visually lossless JPEG 2000 video encoding at 100 Mb/s. JPEG 2000 is an ideal codec for this application, providing superior final image quality when used in conjunction with other codec processes such as MPEG or H.264 for satellite transmission and cable distribution.
■16 embedded audio channels are provided. Alternately, two +4 dBu analog channels are available. Audio I/O is on chassis-mounted gold-plated XLR-3 connectors. Available options allow for 8 channels of AES/EBU.
■ATC Time Code is reproduced, as well as up to 12 selectable lines of Vertical Interval Ancillary (VANC) data. (In 1080i 6 lines from field 1 are selected, and the corresponding lines in field 2 are automatically selected.)
