Frame Rate Conversion provides the ability to change between a variety of different frame rates. This is done by tracking the vector motion of each group of pixels, then crafting a whole new set of frames at the new rate. FOR-A's years of experience in digital video processing makes us the leader in this new HD technology.

Frame Rate Conversion Using Motion Compensation Processing Technology
One major problem with linear converters performing simple frame rate conversion is their inability to perform suitable conversion on moving objects. In the FRC-7000, FOR-A's long experience in video processing technology was used to develop a motion compensation processing technique based on motion vectors. The motion vector of the object is detected, and movement of the interpolation frame object is generated based on the object’s amount of vector movement in the frames just before and after the calculated area. The result is frame rate conversion with minimum judder.

Scene Cut Detection
Another problem in frame rate conversion is the processing of scene changes. Because an interpolation frame is generated from the frames before and after, the process can fail to convert the video properly by combining the frames before and after the scene boundary. The FRC-7000 incorporates a scene cut detection function. Scene changes are automatically detected so that frame rate conversion is performed without using motion compensation processing on unrelated data for the frames before and after scene cuts.

FRC-7000 options

FRC-70DA16 : Digital Audio Multiplexer/Demultiplexer
Expanded function version of the audio expansion card FRC-70DA for adding to the FRC-7000. Supports up to 16 channels of audio signals.
In addition to functions of the FRC-70DA, adds the following functions
Supports AES/EBU eight-channel (16ch) input/output. Supports connections with multi-channel audio equipment such as HDCAM-SR.
Comes with stereo 16 channel (Embedded x4, AES/EBU x8, Dolby E ENC x4) individual delay adjustment function
Comes with automatic assignment function and automatic delay adjustment function for input/output, including Dolby signals

FRC-70DE-E : Dolby E Encoder
A Dolby E encoder card that can be installed to the FRC-70DA. Enables output of audio signal embedded in HD-SDI signal or AES/EBU input signal as Dolby E signal.

FRC-70D-D : Dolby Digital/AC-3 Decoder
A Dolby E and AC-3 decoder card that can be installed to the FRC-70DA. Input Dolby E or AC-3 signals can be output as AES/EBU or embedded into HD-SDI signals.

FRC-70PSFC : 1080p/PsF Support
Improvements to motion estimation/compensation performance now enable smooth motion conversion even when converting from low frame rates to high frame rates such as from 1080/23.98PsF to 1080/59.94i.

FRC-70DA : Digital Audio Multiplexer/Demultiplexer
An audio expansion card to add to the FRC-7000. Enables multiplexing /demultiplexing of asynchronous/synchronous digital audio signals (AES/EBU) for the FRC-7000 video signal.
Audio channel remapping function
Comes with stereo four-channel individual delay adjustment function
Comes with BB output terminal synchronized to input/output SDI signal. Allows synchronous signal to be sent externally, so that even when users already have Dolby E equipment in their systems, it enables significant simplification when building Dolby E systems, which tend to be complex when performing frame rate conversion.

FRC-70RU : Remote Control Unit
Remote control unit for the FRC-7000.
Settings of the various parameters of the FRC-7000 can be changed
Saves and calls up 1 - 4 events
One remote control unit can control up to four connected FRC-7000 units
