Studio Technologies Model 5154 Video Generator/Audio De-Embedder Module

Video Generator/Audio De-Embedder Module The Model 5154 Video Generator/Audio De-Embedder Module is a unique device suited for a variety of custom broadcast, post-production, industrial, and corporate multimedia installations. As a member of the extensive 5100-Series of modules, the Model 5154's compact size belies its powerful audio and video feature set. At its most basic, the Model 5154 provides the ability to de-embed up to eight audio channels (four AES3 digital audio "pairs") from a SMPTE-compliant HD- or 3G-SDI video "stream." The SDI source, connected either by way of a coaxial (BNC) or optional fiber optical input, will always be routed to the coaxial (BNC) and optional fiber optic outputs. Should a source not be connected to the SDI input, advanced circuitry within the Model 5154 will automatically generate a broadcast-standard SDI signal. This ensures that devices "downstream" from the Model 5154 will always be presented with an active SDI signal. Rather than only reproducing one fixed test pattern, the Model 5154 has the capability to store and output two custom high-definition video images. The images, one for "720" and one for "1080," are based on bitmap (.bmp) files that can be created using a personal computer's graphics program. For convenience, the .bmp files are loaded into the module's non-volatile memory via a standard USB flash drive. The appropriate "720" or "1080" image is automatically connected to the SDI output whenever an SDI input signal is not present. The Model 5154's video signal generation capability can be extremely useful, serving as both a "keep-alive" signal as well as allowing a detailed graphics image to be displayed for identification purposes. To clarify, when a valid HD- or 3G-SDI signal is connected to the module's input it will have eight of its audio channels de-embedded, as well as passing through, unchanged, to the module's output. Only when an input is not present will the custom image be generated. (Note, however, that no audio signals will be generated.) The format and rate of the custom image will match that of the previously-connected input signal. This "learning" capability allows a module to automatically adapt to the SDI format and rate utilized by a specific facility or application.
