PUBLIC NOTICE Federal Communications Commission 445 12th St., S.W. Washington, D.C. 20554 News Media Information 202 / 418-0500 Internet: http://www.fcc.gov TTY: 1-888-835-5322 DA 07-1564 Released: March 30, 2007 OFFICE OF ENGINEERING AND TECHNOLOGY SEEKS COMMENT ON MEASUREMENT REPORT OF DTV RECEIVER INTERFERENCE REJECTION CAPABILITIES ET Docket No. 04-186 Comments due: April 30, 2007 Reply comments due: May 15, 2007 On October 12, 2006, the Commission adopted a First Report and Order and Further Notice of Proposed Rule Making in ET Docket Nos. 04-186 and 02-380 to permit the operation of new low power devices in the broadcast television spectrum on channels/frequencies that are not being used for authorized services. In that action, the Commission also stated that its Laboratory was conducting a testing program to quantify the interference rejection capabilities of DTV receivers and intends to issue a report of the results of these measurements by March 2007. The Commission’s Laboratory recently completed this testing program and released a report of the measurement results: - The testing program examined the out-of-channel interference rejection performance of a representative sample of eight DTV receivers with fifth generation tuners that were available in 2005 and 2006. - A total of 2055 individual measurements were performed on these receivers. - Each test involved feeding a desired signal to the television under test and injecting an interfering signal on a different channel or combination of channels. The different tests varied the level of the desired signal and interfering signal(s). - The results show the interference rejection capabilities of the DTV receivers that were tested. - The information from these tests is generally useful to analyze the potential for interference to DTV broadcasts from out-of-band signals. However this information is only one element of many that must be examined in evaluating the possibilities for operation of new low power devices in unused portions of the TV broadcast bands. 2 This report is available through the Commission’s Electronic Comment Filing System (ECFS) at http://www.fcc.gov/cgb/ecfs/.
