The HXC2000C02 is a 3G/HD/SD-SDI digital video format converter that can convert between signals with the same field frequency (50 Hz or 59,94 Hz) and perform the necessary deinterlacing, scaling and aspect ratio conversion. In order to perform format conversion the HXC2000C02 includes an advanced deinterlacer with motion compensation and a sampling structure converter with horizontal and vertical polyphase filters capable of both upconversion and downconversion.
This module has been designed to work together with the UXC2000C01 unit, which has a 12G-SDI to 3G-SDI up-converter and a 12G-SDI to 3G-SDI down-converter, to perform any conversion between digital video formats 12G/3G/HD/SD-SDI that have the same field frequency (50 Hz or 59.94 Hz).
The HXC2000C02 includes an interface to exchange information with the UXC2000C01 installed in the left slot via the chassis rear bus. This interface allows the two modules to work together as if they were one, controlled from the control application of the HXC2000C02.
The HXC2000C02 module includes a 3G/HD/SD-SDI video input (IN), a 3G/HD/SD-SDI video output for the converter and synchronized signal distributed over two connectors (OUT1/OUT2) and an analog reference input with loop-through (REF. LOOP).
The HXC2000C02 module can decode both Coded Frame Aspect Ratio (CF) and Active Format Description Code (AFD) information present in the input signal in order to determine the necessary format conversion. Information regarding the format can come in the form of ancillary data packets as per SMPTE 2016-3 or coded as Video Index Information VII or Wide Screen Signaling (WSS) as per SMPTE RP 186 (VII), ITU-R BT.1119-2 (WSS, 625 lines) and JEITA CPR-1204 (WSS, 525 lines). Format information can also be inserted into the output signal in accordance with these standards.
In addition to converting the format of the video signal, the HXC2000C02 can pass the audio, teletext and timecode information present in the input video signal to the output. When passing audio both channel reassignment and gain adjustment of the pairs if desired.
The HXC2000C02 module can function as both a frame synchronizer and a delayer. For frame synchronizer operation the output video signal is synchronized to the analog reference signal, whereas for delayer operation the output video signal is synchronized to the input video being received for format conversion.
