teChnology & standards boxes used to receive terrestrial DTV signals. That same month, CEA-2022, Digital STB Active Power Consumption Measurement, became an American National Standard. It specifies how to measure the power consumption of a digital set-top box when it is on (i.e., delivering video to a TV set or other device). It does not set limits on power consumption. CEA-909-A, Antenna Control Interface, published in July as well, enables “smart” DTV antennas to be connected to smart antenna-capable DTV sets with a single coaxial cable. The previous version of the standard required another control cable in addition to the coaxial cable. The smart antenna interface enables consumers to use indoor (or outdoor) antennas with their TV sets and receive different local over-the-air signals without having to readjust the orientation of their antennas manually. It is being considered for approval as an American National Standard currently. Published in May, CEA-608-D, Line 21 Data Service, updated an existing standard that explains how to send and receive closed captioning and other data services embedded in line 21 of the vertical blanking interval of an NTSC video signal. This standard is being considered for approval as an American National Standard. Summing up video standard work for the first part of 2007, CEA-2020, Other VBI Waveforms, defines four vertical blanking interval waveforms carried on analog TV signals— two used by Nielsen Media Research, and two used by Gemstar/TV Guide. The electrical characteristics of the waveforms are defined, but the meaning of the data that is transported via the waveforms is not. It was submitted for final approval as an American National Standard in August. Approved as an American National Standard in September, CEA-931-C, Remote Control Command Pass-through Standard for Home Networking, defines methods for communicating basic remote control functions between devices on a home network. makInG LOuDSPEakERS SaFE On the audio front, CEA-CEB19, Recommended Loudspeaker Safety Practices, provides guidelines that manufacturers may use, in conjunction with their own safety specifications, to ensure that loudspeakers are safe. The new standard was published in August. STanDaRDS FOR CE On THE GO FOCuS On HOmE nETWORkS With the new digital technologies in consumers homes, more standards are needed in relations to home networks. CEA-2014-A, Web-Based Protocol and Framework for Remote User Interface on UPnPTM Networks and the Internet (Web4CE), published in July, defines how to produce remote user interfaces for UPnPTM devices. Additional work to extend the functionality of CEA-2014-A is underway. CEA-2015, Mobile Electronics Cabling Standard, defines size and performance requirements for power and speaker cabling used in mobile electronics applications. It was created to address the problem of “undergauging,” where a supplier provides a cable that is ostensibly of a particular thickness, but in reality contains less copper than expected.
