AVQ1050 - ATSC 3.0 BPS Receiver and Synchronizer

Based on the industry verified ActiveCore® Platform, the AVQ1050 device supports two functional modes of operation – a BPS Synchronizer and a BPS Receiver. In the Synchronizer mode, it constantly measures and adjusts the emission TAI time stamp of ATSC 3.0 Frame Preamble. The adjustments are sent directly to a BPS enabled exciter via a dedicated network interface. Assuming that the broadcast signal delivers a correct TAI time stamp, in the Receiver mode the device can synchronize its clock using the ATSC 3.0 signal. Based on the carried in a PLP BPS info and the precise ATSC 3.0 Bootstrap info, the receiver can maintain a very accurate internal clock and provide reference 1PPS and 10MHz signals for external equipment. Besides the BPS functionality, the receiver offers a comprehensive set of tools for monitoring, analyzing, and troubleshooting the RF signal quality, a detailed analysis of each component of the ATSC 3.0 physical layer framing structure, and Avateq’s proprietary in-band interference and link margin estimation.

Proprietary TxID Explorer and CIR deconvolution tools for Time of Arrival (TOA) of the earliest significant multi-path component detection for ATSC 3.0 signals provides an additional level of capabilities for SFN applications troubleshooting, management, and verification.

With the ability to provide spectrum sharing and bandwidth usage statistics for each service, the receiver can be used for building metered/managed content delivery networks.
