Televisa has deployed Enensys Technologies switcher technology as part of a wider DTT network roll-out.
The French company has delivered a large volume of its ASIGuard II switchers for installation at transmitter sites across Mexico, as well as its new platforms for secure microwave links in seamless switching mode.
"The main purpose for the inclusion of Enensy's technology in our ATSC DTT network infrastructure is to provide a highly reliable ASI stream that is delivered onward to DTT transmission systems," said Sergio León, DTT compression systems manager at Televisa. "We are confident in the stream analysis capabilities of Enensys' equipment, and we can let the switch decide which stream is on air."
Thanks to integration with Ericsson Compass system, Enensys' smart switch is able to provide real-time status updates of ASI stream structures and automatic switching between two ASI sources. If errors are detected in the on-air stream, the system will automatically switch to the second stream if this offers a better signal.
"Easy integration with the Ericsson Compass system makes Enensys' switcher technology ideal for this project as we are facing a tight deadline with the imminent analogue switch-off", added Juan Pablo Alonso, CEO at SIS Electron, Enensys' local partner.
"Our ASIIPGuard switcher has been designed from the ground up to address the requirements of network operators such as Televisa, optimising network capacity and enabling them to meet the needs of specific audience segments, with a high level of reliability," explained Emmanuel Jacques, sales manager at Enensys.
