The 8510 Audio Processor is a sub module option for use with the 8500 Video Processing Frame Synchronizer. The 8510 adds both analog and digital audio capability with a flexible architecture that addresses a wide range of audio handling needs. When the 8500 is being used as a video A to D converter, the 8510 can perform the same function with the associated audio. If the 8500 is being fed an SDI signal with embedded audio, the 8510 can produce an analog output of that audio. When using the 8500 as an SDI frame sync, the 8510 can properly resynchronize the embedded audio content.
