Two PBS affiliates—KQED-TV in San Francisco and KNME-TV in Albuquerque, New Mexico—have selected Triveni Digital’s StreamScope for compliance measurement of their DTV transmissions.
The StreamScope allows broadcasters to record, monitor, measure, and analyze DTV streams and signals. Broadcasters can validate reception of their ATSC DTV signals and transport streams throughout their geographic coverage base, while ensuring compliance of their ATSC transport streams with ATSC standards.
The measurements for the stations were handled by SignaSys, a systems integrator based in San Jose, Calif. SignaSys recently launched a Targeted Service Offering (TSO) providing ATSC Compliance Reports for stations that aren’t yet ready to invest in this type of equipment.
Such reports provide a detailed look at a station’s DTV transport streams for compliance with ATSC standards. Customers receive a report focusing primarily on ATSC Program and System Information Protocol (PSIP) standard, audio and video buffer usage, and Program Clock Reference (PCR) frequency and jitter.
SignaSys offers various methods for generating the report via Triveni Digital’s StreamScope. The simplest method allows a station to record its off-air signal on a SignaSys-provided off-air recorder, and SignaSys runs the report at its San Jose headquarters.
