RF Capture Program
OMVC RF Capture Program Overview
The Open Mobile Video Coalition continues to promote system improvement work through its work on Mobile DTV RF measurements and the RF signal capture program. Capture of RF television signals is an efficient and cost effective method of assisting broadcasters and receiver designers to better understand their reception environment. The RF signal capture program was initiated in March 2010 to create an RF signal library to assist broadcasters in better understanding their reception environment and to help mobile device product developers improve their products. The OMVC acquired an RF capture / playback device from Adivic and will offer it to all interested participants, including standards organizations, along with the RF signal library.
RF CAPTURE CATALOG
The RF Capture Catalog is a collection of profiles that allow broadcasters and product developers to play back these profiles in the laboratory for more thorough analysis and evaluation of the Mobile DTV RF environment. Different captures of RF television signals help broadcasters determine the relative performance between the two services and their expected coverage.
