Abstract: A filler module is slidably mountable in an otherwise unused slot of a multi-slot, multi-module electronic system housed in a casing. The filler module includes a relatively compact housing which engages an EMI gasket and an electric connector in an unused slot at the backplane of a shelf in the casing. The module also includes a non-conductive, rigid extension element which facilitates air flow between adjacent modules within the rack. The extension element may include electrically conductive strips which provide ESD protection during the insertion of the module through intimate contact with a grounded, resilient contacting surface. The module may also comprise a non-conductive bulkhead with pivoted latches which engage the casing to secure the housing to the backplane. In this way, a filler module is achieved in which EMI containment is accomplished in a modular fashion and air flow is maintained in the shelf independent of the number or position of used and unused slots.

Abstract: A video processing system includes but structure, signal flow, and components to process and combine audio and video signals with improved power, cost-effectiveness, and flexibility. The system includes one or more input modules to convert input video signals to a predetermined format. A router routes converted video signals to selected ones of upstream processing cards, which perform video processing such as digital video effects, frame synchronization, non-linear editing, cascading, filtering, and the like. Signals from the upstream processing cards are directed to a switcher, which selectively mixes the upstream-processed signals. A switcher preview module may be provided to intermediately view signals provided by the switcher. The switcher is also attached to a series of downstream video processing cards, which may insert logos, add overlaying, and other suitable post-mixing functions.
