FRS-3901 3G/HD/SD Frame Sync with Embedded Audio Processor

The FRS-3901 is a highly integrated module which offers frame synchronization and video/audio processing, including color correction and delay, for 3G, HD and SD signals in 3G/HD/SD hybrid plants. The FRS-3901 features an advanced embedded audio processor which can simultaneously process up to 32 channels of audio (16 channels of embedded audio from the video plus others generated internally). Functions include downmixing, proc amp, channel shuffling and mixing, and loudness measurement. The FRS-3901 generates audio/video fingerprints (via an iControl option) to detect and measure lip-sync errors in a broadcast facility.

FEATURES

Video
  • 3G/HD/SD frame synchronizer, delay and line sync
  • Supports 3 Gb/s level A (mapping 1) and level B
  • Flexible HD/SD/URS reference input
  • Video delay up to 15 frames
  • Audio/video de-glitcher to handle video hot switch at the input
  • Automatic detection of input video loss and switchover to local grey for continuity of embedded audio
  • Built-in proc amp with YUV/RGB color correction
  • Bypass relay with FRS-3901-3SRP-R rear module
  • Optional optical fiber module I/O with FRS-3901-3SRP-F rear
  • Compatible with iControl end-to-end A/V fingerprint analyzer for lip sync error detection and measurement

 

Metadata
  • AFD (SMPTE ST 2016), VLI (RP-186) and WSS insertion
  • Audio metadata insertion and extraction (SMPTE ST 2020-A)
  • RS-422 serial data input and output to carry audio metadata
  • 3 GPI inputs and outputs that can be inserted or extracted in the timecode user bits. They can also be used for automation, user preset recall and loudness reset.
Audio
  • Full audio shuffling and mixing on a channel basis
  • 32 channels internal audio processing
  • Audio 5.1 surround downmix to Lt/Rt or Lo/Ro
  • Loudness measurement of up to four audio programs and logging with iControl loudness monitoring option
  • Loudness compliant to EBU R128-2014, ATSC A/85:2013 (FCC CALM compliant) and ARIB TR-B32 (ITU-R BS.1770-3)
  • Automation capabilities based on audio signal type detection
  • Audio delay adjustments of up to 2 seconds to compensate for lip sync issues
  • On-board socket for one optional module expansion:
    • Dolby E and Dolby Digital decoder
    • Dolby Digital and Dolby Digital Plus encoder
    • Dolby E encoder
    • Linear Acoustic upMAX
    • Linear Acoustic AEROMAX automatic loudness control
