7746FS-EAES8-HD
HD/SD-SDI 8 AES Frame Synchronizer
The 7746FS-EAES8-HD HD Frame Synchronizer is designed to re-time a SMPTE 292M (1080i/60, 1080i/59.94, 1080i/50, 1080p/24sF, 1080p/23.98sF, 720p/60, 720p/59.94, 720p/50, 1035i/59.94, 1035i/60, or 480p/59.94) or SMPTE 259M (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. During the synchronizing process the video delay varies from 3 lines through to 1 frame plus 3 lines. Additional delay can be added to the synchronizing process in 1 frame increments.
On the 7746FS-EAES8-HD version, the user can choose to have 8 stereo pairs from 4 groups in the upstream embedded audio and from the 8 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.
The frame synchronizers have the ability to adjust video parameters such as brightness, contrast and saturation. Hue control is available for SD standards (525i/59.94 and 625i/50). They can also adjust audio parameters such as gain, invert, two-channel mixing, and reassignment of audio channels. The embedder and AES outputs can individually choose between two independent audio mixers.
