Axcera DXA2B allows digital distributed transmission


The DXA2B accepts a SMPTE 310M data stream with embedded placeholder packets and outputs a modified SMPTE 310M stream.

The Axcera DXA2B distributed transmission adaptor is designed to work with two or more slave transmitters to allow multiple signals to be broadcast in overlapping coverage areas on the same channel using the ATSC candidate standard for distributed transmission.

To achieve the necessary synchronization, the DXA2B accepts a SMPTE 310M data stream with embedded placeholder packets and outputs a modified SMPTE 310M stream. The modified stream includes cadence sync for system timing and distributed transmission packets that contain all of the information necessary to operate the network.

The signal is then transported to the slave transmitters through a standard digital studio-to-transmitter link. The slaves accept the modified SMPTE 310M stream and respond to the cadence sync and distributed transmission packets, synchronizing their symbols, timing and pilot frequencies. Frequency synchronization and timing reference is achieved through GPS receivers at each location.
