Avenue 5160 SD Protection Switch and DA
The 5160 Serial Digital Protection DA module is a fail-safe bypass protection switch for monitoring and switching critical digital paths. When a fault is detected in the Primary input, the switch will activate, causing the Secondary (backup) input to be switched to the module’s distributed outputs. The switch can operate in two modes; automatic or nonresetting. The 5160 monitors the integrity of the Primary serial digital input stream and analyzes the audio and video content. Signal health and fault detection is determined by monitoring any or all of the following parameters: Timing Reference Signal (TRS), Black, Embedded Audio, Error Detection and Handling (EDH), and Freeze. A sophisticated Black detection system is employed to activate the switch in the event signal is lost. It allows the user to select not only the threshold and percentage of nonblack pixels, but also the portion of the picture to be considered. The Freeze detection system can be set to detect a clean or noisy source. Freeze Time sets the number of seconds for the 5160 to switch to the secondary input after a video freeze condition is detected in the primary input.

Avenue 5820 GPI / Serial Interface
The 5820 GPI/Serial Interface module extends the capability of the Avenue control system enabling third party equipment to control Avenue modules. The 5820 provides General Purpose Interface control (GPI contact closure) over modules located anywhere in an Avenue system. It also provides RS-232/RS-422 serial interface access for use with show controllers and automation systems. To use the 5820, just install it in any Avenue frame in the system and connect the 5820’s GPIs or serial interface to your automation system or other third party device. Using the Avenue control system, the 5820’s GPIs and serial inputs can be mapped to any Avenue module in the system. When a GPI or serial command is received by the 5820, a message is sent to the corresponding Avenue module. That module then recalls the specified memory register. The 5820 module takes full advantage of the Avenue control system and is able to communicate with any other module located in any Avenue frame. Using M2M™ (Module To Module) communication, the 5820 acts on GPI contact closures, or serial commands, by sending configuration recall commands to another module. From the serial interface port of the 5820, an external device can also activate the same recall functions. Supporting both RS-232 and RS-422 interfaces, the simple ASCII-based protocol allows easy interconnection to any control system. The 5815 is an optional 1RU control panel that serves as a shot box. It has eight illuminated status push buttons that can also be used for manual override and status in automated systems. Configuration and monitoring of the 5820 is also available through an Avenue Control Panel and Avenue PC software.

Alarm generation, configurable user levels, module lock-out, and customizable menus are just some of the tools included in the Avenue control system. Meta Data HD closed captioning is carried in data packets in the vertical interval ancillary data space. The 7130 properly translates HD caption data to traditional SD captioning (line 21 or 23) so that closed captioning content is converted transparently between video standards and formats. Automatic Aspect Ratio Conversion The 7130 uses WSS (Wide Screen Signaling) and AFD (Active Format Description) to mark or identify the aspect ratio of the video content. These flags are read at the input of the module.
Avenue 7160 Serial Digital Protection DA
The 7160 Serial Digital Protection DA module is a fail-safe bypass protection switch for monitoring and switching critical SD and HD paths in broadcast and satellite applications. When a fault is detected in the Primary input, the switch will activate, causing the Secondary (backup) input to be switched to the module’s distributed outputs. The switch can operate in two modes; automatic or nonresetting. The 7160 monitors the integrity of the Primary serial digital input stream and analyzes the audio and video content. Signal health and fault detection is determined by monitoring any or all of the following parameters: Closed Caption Data, Timing Reference Signal (TRS), Black, Embedded Audio, Error Detection and Handling (EDH), CRCs, and Freeze. A sophisticated Black detection system is employed to activate the switch in the event signal is lost. It allows the user to select not only the threshold and percentage of non-black pixels, but also the portion of the picture to be considered. The Freeze detection system can be set to detect a clean or noisy source. Freeze Time sets the number of seconds for the 7160 to switch to the secondary input after a video freeze condition is detected in the primary input.
Avenue 7400 HD/SD Test Signal and Sync Pulse Generator
The 7400 HD/SD Sync Generator and Test Signal Generator is a stable timing source that is perfect for local reference generation in broadcast, remote trucks and post. HD SDI, SD SDI, analog composite, Tri-Level Sync, timecode, AES audio and analog audio reference outputs are generated. The 7400 can operate from an internal precision frequency reference as a stand-alone Master Sync Generator or lock to a video reference or 10 MHz precision reference. Alternately, the 7400-GPS option can be used. If the external reference is lost, the 7400’s softlock provides a graceful transition to the internal TCXO, ensuring consistent reference output. The 7400 can output multiple formats of Tri-Level Sync, HD SDI test signals, SD SDI and composite test signals, and color black reference. The 7400 can simultaneously deliver both 525 (NTSC) and 625 (PAL) based signals. Color framing tracks the reference signal. All of the video outputs are derived from the same time base and can be timed with respect to each other. The 7400 has two identical generators, Generator A and Generator B, each with a variety of outputs. Each set of outputs can be timed with respect to the reference to any point in the television frame. All of the outputs from a particular generator must be selected within the same frame rate family. The Avenue Frame features a retainer bar to ensure that modules remain properly seated even in the most demanding mobile environments. Favorite Test Patterns There are over 30 test signals including: Full and Split Field Bars at 75% and 100% with Pluge; Black; Flat Field; Pulse and Window; Ramp; Crosshatch; Safe Title; Blanking Markers; Cosite; Checkfield, Pathogenic, and 5 Step. The Cyclops feature adds a motion element to the selected video test signal to assist in locating a signal that might be frozen in a frame sync somewhere in the signal chain. An ID slate with user programmable text can overlay the test pattern. Customizable Test Patterns In addition to the standard suite of test patterns, users can create custom test patterns on a computer. Simply transfer test patterns to the included Secure Digital flash memory card using Avenue Logo software and a standard card reader, then insert the memory card into the 7400. Custom test patterns can also include motion. Audio Generators The 7400 provides extensive support for analog and digital audio. Because all of the video outputs can be locked to a common time base, the AES digital audio outputs are always synchronous with all of the video outputs – regardless of format. Multiple tone generators make it easy to identify multi-channel content. This bitstream will be included in the set of signals that can be embedded into the test signal outputs. The audio section of each generator supports sixteen audio channels. The content of each channel is independently programmable. Choices include adjustable frequency tone generators, tone sweeps, silence and timecode. Left/Right Channel ID that synchronizes to the Cyclops feature can also be selected. All sixteen of these channels can be embedded in the SDI outputs. Each AES output can select from any of the 8 pairs that make up these 16 channels. Similarly, the stereo analog output of each generator can be driven from any of these audio signal pairs. Multiple Timecode Generators Multiple timecode generators make the 7400 convenient for post applications. Timecode is delivered as LTC both 75 Ohm BNC and 110 Ohm Balanced), VITC, and DVITC. One generator can be configured to produce 525/59.94 drop frame timecode while the other generator is making 1080sF/23.98. 7400-GPS Option for the Ultimate Precision Reference For the ultimate in precision, the 7400-GPS option can be used with the 7400 module. The purpose of this GPS option is to provide an extremely precise frequency reference. The oscillator on the 7400-GPS is more accurate than a typical internal precision standard and is equivalent in accuracy to an atomic standard. Increased frequency accuracy makes it possible to frame synchronize signals between different facilities with virtually no dropped or doubled frames. The GPS option also provides precise time of day information, which can be used to drive the 7400 module’s internal timecode generators. The 7400-GPS option seamlessly integrates into the Avenue system by plugging directly onto the 7400 module. It can be easily installed in the field. The 7400-GPS option consists of a compact, weatherproof antenna (with internal high-gain pre-amp) and a receiver sub module which mounts directly to the 7400 module. The included GPS antenna mounts onto standard 3/4” threaded pipe, metal or plastic. Connection from the F-style coaxial fitting on the antenna to the appropriate BNC on the Avenue Frame can be made with customer supplied standard 75 ohm cable. The coax cable can be routed through the center of the pipe for a completely waterproof installation. When low loss cable such as Belden 1694A is used, the antenna can be placed up to 200 feet (60 meters) from the frame. Ideally, the antenna is mounted outdoors where it has an unobstructed view of the sky. A Complete SPG and TSG System The 7400 can be combined with other Avenue modules to create a complete sync pulse and test signal chain. The 7410 is a four channel HD Tri-Level Sync generator that can output four different types of Tri-Level Sync simultaneously and is very useful in post and hybrid facilities. The 5150 distribution amplifier can be used to distribute multiple copies of AES audio, Tri-Level Sync or composite black signals as needed. For HD test signal and black distribution, the 9110 DA is a good fit. Description of Outputs: Generator A SDI Out A – Outputs HD or SD test signals. Select frame rate family for all of Generator A; 59.94, 50 or 60. Output can include 16 channels of embedded audio. The embedded audio can be any combination of the following: tone, silence, external audio. Can also include DVITC. Programmable Out 1A – Outputs analog composite black, composite 100% bars, or Tri-Level Sync from TLS Gen 1. When SDI Out A is a SD test pattern, this BNC can also output a composite version of that test pattern. Composite output can include VITC. Programmable Out 2A – Outputs one of the following: Tri-Level Sync from TLS Gen 2 (can be different from Out 1 A), LTC, AES (any of 8 pairs), AES silence, Word clock, 6 Hz pulse, 10 MHz (only if locked to internal or GPS reference).

The logo insertion capability can be used to add letterbox framing. It can also be used to key sports or event logos, or to source a virtual set background. The on-board memory can play back almost a minute of uncompressed video. Handy Flash Memory The 7420 is fitted with a Secure Digital flash memory card in order to provide an extremely fast and easy way to transfer material. This is a particularly convenient method for pre-building material off-line. Simply transfer logos and animations to a Secure Digital flash memory card using a standard card reader, then insert into the 7420. The 7420’s flash memory card can be removed and reinstalled without interrupting logo playback. Alternately, logos can be loaded into one or more 7420s over Ethernet. The flash memory card is used for transfer while the actual logo and animation playback comes from the 7420’s DDR2 memory. Linear Keying The 7420 provides two cascaded, full linear keyers with transparency and a programmable transition rate. Each keyer is independently controllable and each has independent access to up to 2 GB of stored video. Standard configuration is Keyer 1 and 2 each populated with 1 GB of DDR2 (SODIMM) memory. Users can upgrade to 2 GB of DDR2. Audio Support Sound and voice-overs can be associated with logos and clips. Each keying channel can playback a stereo sound file simultaneously with video. Audio is mixed into the user-selected output channel. Avenue Logo Authoring Environment The Avenue Logo authoring environment provides a means to import graphics, animations and sound files. Video files are converted to the appropriate SD or HD color space, adjusted for proper aspect ratio, and organized in a form suitable to download into the 7420. Lossless compression ensures logos, animations and clips look as good in the program output as when they were created. The authoring system allows importing sound files which can be associated with one or more still or animated logos. Video and audio files are associated through the Avenue Logo authoring software. Avenue Logo software can be provided to your clients so they can build sports or event logos off-line. Control Playback of sequences can be issued through a variety of methods. All Avenue modules can be accessed via Ethernet with Avenue Logo software, Avenue PC software, or through third-party support using TCP/IP or SNMP protocols. Automation interfaces can be made through a simple ASCII protocol via the RS-232 port specific to the module. Single GPI contact closures can be used to initiate logo sequences.
