In planning for the switch from analog to digital TV broadcasting, officials appear to have ignored millions of owners of portable battery-powered analog TVs, the Los Angeles Times observed today (Monday). The tiny sets are often used in case of power failures (or at sports events) and cannot be attached to converter boxes because the boxes themselves require a power source. According to the Consumer Electronics Assn., eight million homes rely on hand-held TVs in case of emergency, all of which will become obsolete on February 18. However, the Times noted, one converter box maker, Winegard Co., plans to offer a $20-25 battery pack for its models next month.
