Digital-to-Analog Video and Audio Monitoring
The EAS6800+B2A4D/C2A4D modules are broadcast-quality video and audio digital-to-analog encoders for the 6800+™ core processing platform. The modules accept one SD-SDI input, synchronize the video and convert into a composite analog output (NTSC, PAL-B, or PAL-M). The modules also accept embedded and discrete AES audio inputs for conversion and output of up to four analog audio channels. Comprehensive video and audio processing capabilities exist via integrated video and audio processors..
The EAS6800+ modules can be can be controlled manually via card-edge controls, or controlled and monitored via the CCS Navigator™ software application, HTTP web browser, NUCLEUS™ hardware control panels or third-party SNMP-based control applications. The modules are Q-SEE™-compliant, allowing for direct thumbnail monitoring when installed in an Ethernet-equipped 6800+ frame.
Features
- Jumper-selectable audio level (0 dBFS) for each channel
- Support for up to 24-bit audio de-embedding
- Audio processing amplifier with controls for gain, invert, mute and channel multiplexing (including summing for mono-channel production)
- 16-, 20- or 24-bit audio processing (selectable word length in channel pairs)
- Audio test tone generator
- Programmable audio delays (up to 1.32 seconds per input channel)
- Composite encoder encodes 4:2:2 digital video into a composite analog signal; supports NTSC, PAL-B and PAL-M output video formats
- Video processing with controls for black level, luminance gain, chrominance gain, chrominance phase and SCH offset
- Frame synchronization to reference video input
- Line synchronization within a three-line window of input video
- Q-SEE-compliant
