FRS-3901
3G/HD/SD Frame Synchronizer 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.
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
