In Technical Appendix 1, item 15, there is a Criteria A or B for echo performance. Is one better than the other?
The Final Rule permits manufacturers to choose Criteria A or B – NTIA does not express a preference for either table. In their test results, manufacturers should specify whether the model was tested against Criteria A or Criteria B. If Criteria B is chosen, manufacturers should identify which 37 of the 50 field ensembles were tested successfully. See NTIA’s Notice, published on May 30, 2007 in the Federal Register, (www.ntia.doc.gov/ntiahome/frnotices/2007/DTVmanufacturer_053007.
