Markertek News Channel coverage of all the new Redbox solutions from Sonifex at NAB 2009. Products covered include the RB-VHDA8, a high performance, reliable eight way digital video distribution amplifier for re-clocking and distributing an HD (high definition) or SD (standard definition) SDI source to eight outputs. The unit provides automatic input detection, re-clocking and cable equalisation of the input signal to 200/400 meters (HD/SD) of coax cable; as well as the RB-PD2 Stereo Profanity Delay, a stereo audio profanity delay used for live broadcast programs to prevent unwanted or obscene material from being transmitted. It features an automatic audio stretch algorithm that allows between 2 and 55 seconds of delay to be built up live whilst "on air", whilst maintaining the correct pitch. The delay can also be acquired whilst playing a pre-selected audio file on a CompactFlash memory card. When the program is complete, the audio stretch algorithm seamlessly reduces the delay to zero.
