DESCRIPTION 1.1. The HXC2000C01 The HXC2000C01 is a 3G/HD/SD-SDI digital video format converter that can convert between signals with the same field frequency (50Hz or 59,94Hz) and perform the necessary deinterlacing, scaling and aspect ratio conversion. In order to perform format conversion the HXC2000C01 includes an advanced deinterlacer with motion compensation and a sampling structure converter with horizontal and vertical polyphase filters capable of both upconversion and downconversion. The HXC2000C01 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 HXC2000C01 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 HXC2000C01 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 HXC2000C01 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. It is possible to monitor the HXC2000C01 status remotely using a communications controller module installed in the same mounting frame. In addition, certain controller modules provide SNMP management and the ability to record events in a file including date and time information for further analysis. The HXC2000C01 is a TL2000 terminal line module and can be housed in a two rack unit (2 RU) UR2000 mounting frame. 5 Albalá Ingenieros | Manual HXC2000C01 1.2. Features • 3G/HD/SD-SDI digital video signal format cross-converter with frame synchronization. • Provides: - One 3G/HD/SD-SDI input. - One 3G/HD/SD-SDI output resulting from conversion, synchronized and distributed to two connectors. - One analog reference input with loop-through. • Deinterlaces the input signal using a robust motion-compensated algorithm. • Allows pass through of the embedded audio, teletext and timecode in the signal from input to output. • Includes an audio matrix with gain control capable of reassigning the audio pairs at the SDI input to the SDI output. • Inserts VII, WSS and SMPTE 2016-3 information into the down-converted signal. • Can operate in sync with the analog reference or with the digital input signal itself. In both cases both horizontal and vertical delays are adjustable. • Supports the following video formats: - SMPTE ST 424 (3Gbit/s): 1080p50/59.94. - SMPTE ST 292-1 (1,5Gbit/s): 1080i50/5.94, 720p50/59.94. - SMPTE ST 259 (270Mbit/s): 576i50 y 486i59.94. • Can be configured to deliver a test signal (black or colour bars) with a caption or to freeze the last correct frame when the input signal is lost. • The output signal format is configurable: the Coded Frame and its AFD can be calculated automatically or forced manually. • Provides 16 presets for storage of module configuration. • Module control and supervision can be done remotely when the mounting frame is equipped with a communications controller module. • Low power. 6 Albalá Ingenieros | Manual HXC2000C01 1.3.
