ATSC 3.0 Tested in Cleveland

The first live ATSC 3.0 broadcast of a major professional sporting event – Major League Baseball’s World Series – has taken place in Cleveland. The experimental station is simulcasting network and local programming from local Fox affiliate WJW-TV.

The NAB received an FCC experimental licence to operate a full-power Channel 31 transmitter in Cleveland as a laboratory for broadcasters and manufacturers creating the Next Gen TV service. The ATSC 3.0 broadcasts are using the transmitter and broadcast facilities of WJW, the Tribune Media-owned Fox affiliate in Cleveland.

In addition to the support of Tribune Media, Fox and the NAB, the ATSC 3.0 World Series broadcasts are made possible by technical contributions of GatesAir (ATSC 3.0 exciter for over-the-air transmission), LG Electronics (ATSC 3.0 receivers and antennas), Harmonic (real-time encoders for HEVC video and Dolby AC4 audio) and Triveni Digital (signaling/announcement metadata, IP stream generation, ATSC 3.0 analyzer, and system integration support).
