Enhancing Video Router Design
Many routers are limited in that they are fixed at a specific size, but new technology is increasing the usefulness of modern video routers for improved flexibility
travel through with the data. This method is also very convenient for multiple point monitoring, for example in the case of a relay position, the insertion of the hop count and forwarding the history of the previous hop at the end of the path. Users can also monitor everything that has happened at a previous link, even if that link site itself is unavailable in terms of being connected to public internet or other data mechanisms. Avenue’s DVB-ASI transport stream monitoring system is content-agnostic as there is no analysis or decoding of the stream; the system is simply testing to see if the data given was delivered accurately. ■

The Avenue modular digital video router from Ensemble Designs uses new technology for configuration and display which makes it different from existing routers. This new router has a flexible matrix design which allows the user to configure the precise number of inputs and outputs. The design is future-proof, allowing the router to be easily reconfigured. If a broadcast station or video facility has, for example, more sources than destinations, the router could be configured as a 22x8 or 25x5 matrix. The ease of expansion, userdefinable input / output port geometry, unique video thumbnails, built-in test signal generation, and optional clean and quiet switching on multiple outputs

makes it suitable for high-end broadcast use. Applications include QC monitoring, master control bypass switching, ENG trucks, and edit suites. Real-time video thumbnails travel over Ethernet to the Router Control Panel where they are displayed on a compact, high resolution display. This enables the operator to visually verify source content before performing any switching operations. The Avenue router’s optional clean switch provides full frame synchronisation so it can even switch cleanly between asynchronous SDI sources. While some routers provide a line sync or no clean switch at all, the Avenue router’s clean switch has a full frame sync which means the output can be timed anywhere in the television frame. Asynchronous sources can be switched live to air. In addition to the router, the Avenue platform includes many signal p ro c e s s i n g modules upconverters, a u d i o embedders, sync reference generators

and MPEG processors. New vetting and clean switch technology is used in the Avenue 4445 module which is a smart DVBASI switch that combines analysis of the transport stream with auto alignment of packet timing. It is both a clean switch and a fail-safe bypass protection switch for use with critical, live feeds. The content analysis logic includes ETR 290 compliant testing and automatically identifies transport stream faults. Ensemble’s approach to verifying the transport stream is to calculate a check sum across a group of data packets. This method was developed in the lab at Ensemble as a way to verify that perfect data integrity was maintained as transport streams were buffered through memory. Ensemble then decided there were ways to apply this concept in the field, by taking individual data packets within consecutive packets within a short block of time. Then a check sum is computed to be slipped into the stream, to have it
