HD/SD-SDI Embedded Audio/8 AES Support Frame Synchronizer

The 7847FS-EAES8 series Frame Synchronizers are designed to re-time a SMPTE ST 424 (3GB/s), ST 292-1 (1080i/59.94, 1080i/50, 720p/60, 720p/59.94) or SMPTE ST 259-1(625i/50, 525i/59.94) input to a local reference tri-level or composite sync signal. When necessary, frames are repeated or dropped to maintain synchronization. The 7847FS-EAES8 supports synchronization of both the video and any embedded audio present including the preservation of all VANC data. When the input video is lost, this module will freeze the last good frame or generate black video.

On the 7847FS-EAES8, the user can choose to have eight stereo pairs from four groups in the upstream embedded audio and from the eight AES inputs embedded on the output video and output as AES. The module can also pass all VANC data after switching line. When the input video is lost, it will pass the input AES or mute if embedded audio is selected for synchronizing.

The frame synchronizers also have the ability to set the audio delay independently from the video delay and have the ability to adjust many video parameters such as brightness, contrast, saturation and hue control. The adjustment of audio parameters such as gain, mixing stereo pairs into monaural and reassignment of audio channels is fully supported on up to 16 channels of embedded audio.

The +SCTE104IP option allows for advanced SCTE104 processing. The module can author various SCTE104 messages and trigger them based on GPI's or SNMP commands, or can parse and pass-through SCTE104 messages based on an incoming IP connection, for use with automation systems. The module output can also be steered by SCTE104 splice request commands, allowing it to be used as the switchpoint for commercial insertions.

IntelliGain™ Audio and Loudness Processor

• Consistent audio loudness levels within a channel and/or program
• Automatic detection and level adjust for loud commercials
