The PRVA-4063/E broadcast changeover protects a complete channel providing composite video and analog audio support. The main and the stand-by lines may be analog, digital (an output of MPEG decoder) or combination of both. Video sources may be up to 15 TV frames out of phase to each other, audio may have up to 600msec relative delay.
The PRVA-4069 broadcast changeover protects a complete channel providing HD/SD SDIembedded support. The signal sources may be up to 30 seconds out of phase to each other. Relay bypass on power down. Automatic changeover mode with manual override (local and remote: web and GPI). Remote controls and management via Ethernet.
Provides an emergency bypass for analog or digital lines.
Relay video baypass modules (PRB-097, PRB-102, PRB-103): three channels for an analog composite (PAL, SECAM) or component (YUV, RGB, YC), digital (SD SDI, DVB-ASI) and HD SDI (PRB-102, PRB-103 only) video and unbalanced digital audio (AES/EBU) signals. BNC connectors. The GPO reports the module status: when in BYPASS (PRB-102, PRB-103). Automatic BYPASS (PRB-097, PRB-103) or keep the previous state (PRB-102) on POWER DOWN condition.
Relay audio bypass modules (PRB-098, PRB-100A, PRB-101A): two channels for analog stereo or balanced digital AES/EBU signals. XLR connectors. The GPO reports the module status: NORM or BYPASS (PRB-100A, PRB-101A). Automatic BYPASS (PRB-098, PRB-101A) or keep the previous state (PRB-100A) on POWER DOWN condition.
Video and audio bypass modules (PRB-100, PRB-101): for an analog composite (PAL, SECAM), digital (HD SDI) video and balanced/unbalanced analog and AES/EBU audio signals. XLR connectors. The GPO reports the module status: NORM or BYPASS. Automatic BYPASS (PRB-101) or keep the previous state (PRB-100) through the POWER DOWN condition.
Relay 2x1 video switch (PRB-099): analog composite (PAL, SECAM), digital (SD/HD SDI) video and analog or AES/EBU audio signals. Independent or the "audio follows video" switching modes. The GPO reports the module status: NORM or BYPASS. Keeps the previous state on POWER DOWN condition.
Local or remote (GPI) controls.
A 1U mounting plate is available to fit up to three (PRB-097, PRB-098, PRB-102, PRB-103) video or one video and one PRB-098 bypass module(s) in a 19" rack.
Intended for monitoring of the output signals from the PSG-2070 master sync generator.
Two inputs for a pair of master sync generators. In case of a failure in one of master sync generators – the automatic change over to the valid signal
occurs.
The latching relay facilitates the output path in a power-down condition.
Features:
- Switching of analog (TRI-LEVEL or BB), digital video (3G/HD/SD SDI), analog/AES balanced/unbalanced audio, LTC, 1PPS, 10MHz, WC (48kHz)
- User-selectable list of errors and parameters for monitoring
- Distribution amplifier for output video (BB, TRI-LEVEL, 3G/HD/SD SDI)
- Visual and audio alarm signals for fault conditions
- Rack temperature control
- Automatic or manual changeover switching
-OLED indicator for parameters control/setting and logs
- Ethernet connectivity for remote management
Protects identical digital HD/SD SDI video signals with embedded received digital (satellite, optical, digital radio relays) ang generated in studio audio (video servers, etc.).
With REF signal applied – the seamless switching is guaranteed. Up to 15 TV frames video and up to 600ms of audio offsets supported.
The following set of parameters are analysed:
for SDI signal: SDI loss, EHD errors;
for video: video freeze on main channel;
for audio: audio group loss, audio level drop below the silence threshold (-30~-60dB).
HDMI monitor output with audio level meter OSD. Relay bypass on power down condition Automatic or manual (local or on remote console) recovery switching to the
secondary input. System can be monitored controlled via web-interface or via built-in CPU and Proflex3.xx software. SNMP and SMTP support.
Automatic changeover mode with manual override, local and remote controllable. Signal pass-through with power off and removed module.
Programmable changeover criterions. Errors counter indication. Monitor output for the MAIN line. Programmable changeover delay (up to 8
seconds).
Automatic changeover mode with manual override, local and remote controllable. Programmable changeover delay and criterions with
silence detection capability. User-controllable silence detection: the level threshold and silence duration. Latching dryreed relays for
BYPASS mode on power-down condition (may be activated from a local control panel). Monitor analog output.
GPIO-controllable.

with silence detection capability
Automatic changeover mode with manual override. Programmable changeover delay. Automatic or manual changeback. GPI inputs and outputs. Automatic
standard selection: HD/SD SDI, ASI. EDH status indication in HD/SD SDI signals. Signal loss indication. Monitor output for the MAIN and STDBY lines. PAL/NTSC
monitor output for SDI input signals. Latching dryreed relays for the program lines, electronic switch for monitor output. Latching relays. For non latching relays
add the “NL” index Two optional balanced (PCOV-3326-1) or unbalanced (PCOV-3326-2) audio stereo channels.
Two auxiliary balanced stereo audio channels support (PCOV-3326-2, PCOV-7326-2).
Changeover criterions: SDI – EDH/CRC errors, synchro loss, embedded audio loss; ASI – loss of SMPTE synchro.
Automatic changeover to the stand-by channel on video loss or reduction condition. 1270÷1610 nm optical input range. Manual (local or
remote /GPI/RS485/ETHERNET (in rack CPU requiered)) changeover to the stand-by channel on video loss or reduction condition. Automatic or
manual switching on signal recovery. Operates on power down condition, including CWDM system. FC/UPC type optical connector.
Support optical 3G/HD/SD SDI, AS signals converted into electrical and vice versa. Also support combination of optical main signal,
electrical standby signal and electrical output. Automatic and manual modes. GPI or programmable changeover in manual mode.
Changeover criterion in automatic mode is signal loss or EHD errors in SDI signal. Configured by SFP.
4 BNC connectors and 1 SFP slot. Depending on SFP module automatically configures each BNC connector either as input or output or
pass-through.
Four types of Video SFP: 1. two-channel receiver, 2. single-channel receiver, 3. two-channel transmitter, 4. single-channel transmitter.
SFP should be ordered separately.
