Enensys Technologies, designers and manufacturers of digital TV transmission technologies, has announced that Televisa has deployed its switcher technology as part of a wider DTT (ATSC) network rollout. Enensys has delivered a large volume of its ASIGuard II switchers for installation at transmitter sites across the country, as well as its new ASIIPSwitch and HDc chassis platform, for secure microwave links in seamless switching mode.
Sergio León, DTT Compression Systems Manager at Televisa said, “The main purpose for the inclusion of Enensys’ technology in our ATSC network infrastructure is to provide a highly reliable ASI stream that is delivered onward to DTT transmission systems. We are confident in the stream analysis capabilities of Enensys’ equipment, and we can let the switch decide which stream is on air.”
Enensys ASIGuard II Smart Switch has been successfully integrated with Ericsson´s NMS for monitoring purposes. Thanks to its analysis capabilities, it’s able to provide real-time status updates of ASI stream structures.
ASIGuard II provides automatic switching between two ASI sources – in this case the main and backup encoders – allowing it to be used as a 1+1 redundancy solution. If errors are detected in the “on-air” stream, the system will automatically switch to the second stream if this is offers a better signal.
