CableLabs, the cable television industry standards and testing organization, said digital cable TV plug-and-play products from three digital television (DTV) manufacturers have passed the Joint Test Suite (JTS) tests for verifying unidirectional digital cable products.
Uni-directional products from Sony, Hitachi and LG Electronics/Zenith passed CableLabs' verification panel. Under the Federal Communications Commission (FCC) plug-and-play rules, manufacturers must have their first DTV model tested at either CableLabs or at a qualified test facility.
The testing is performed to show compliance with the JTS that was mutually agreed upon by certain consumer electronics manufacturers and cable operators.
After receiving verification, manufacturers may self-verify DTVs for compliance with the agreed tests, in accordance with the FCC rules.
The FCC rules require manufacturers to ensure all subsequent models comply with the tests. The manufacturer must submit to CableLabs records indicating compliance for each self-verified model.
