There are four video input and output formats supported by the PFS-875; Composite Video, Component Analog Video (YUV), Y/C (S-VHS) and SDI. The component analog video input is YUV (SMPTE), and component output is YUV (SMPTE/Beta-cam). The analog output is on three BNC connectors which can be programmed from the front panel to output all 3 composite, or composite and Y/C, YUV SMPTE, or YUV BETA.
The PFS-875 provides dual standard composite and SDI correction and synchronization to an external analog reference. The synchronizer decodes multiple composite standards (NTSC, PAL). All analog inputs are sampled with 12-bit resolution and decoded using a 5 line adaptive comb filter. It also has a built-in color bar or black burst generator. The PFS-875 can also synchronize non TBC signals from VHS tapes.
When input video is lost, the synchronizer freezes the video or generates a test pattern. There are three ways to freeze the video, freeze to the last known good frame, field 1, or field 2. The test patterns that can be generated are SMPTE color bar for NTSC, 75 % color bar for PAL, and black burst for both.

Audio Embedding & De-embedding
PFS-875 has the feature to embed and de-embed two channels of stereo AES audio. The De-embedded AES audio is output through 2 separate BNCs on the rear panel. Similarly, AES input for embedding can be input through 2 separate BNCs. It has the feature of choosing to embed the de-embedded audio and move the audio to another group or channels. It also has the feature of delaying the audio to match the video delay.
One of the new developments to be included in this product is an all-digital composite NTSC/PAL encoder. The encoding process allows for an image quality superior to any of the off-the-shelf encoder ICs available on the market at present, and also gives a superior gen-lock capability. The encoder process implements 12-bit outputs.
The PFS-875 has the feature of three built-in processing amplifiers. One “proc. amp.” is for the analog output allowing you to control luma, chrominance, Sync, Burst, and Set-up levels along with a black clip and hue phase adjustment. The second “proc. amp.” is for the SDI output allowing you to control luma, chrominance and set-up levels along with a black clip. The third “proc. amp.” is for the analog input affecting both analog and SDI outputs, which allows you to control the luma and chrominance levels along with hue phase adjustments.
