Motorola and rivals Nokia , Samsung Electronics and LG Electronics already offer phones with live TV. Apple's popular iPod and iPhone let users download videos, but does not support live TV.
Motorola said the device, set for commercial launch this month, is expected to be sold by television broadcasters, consumer electronics retailers and wireless carriers.
The DH01 has a 4.3 inch video screen, a feature that lets users pause live TV for up to five minutes and a battery supporting four hours of playback. Viewers can add memory cards storing up to 90 minutes of video.
The new device is compatible with DVBH, a broadcast technology standard for mobile devices that is backed by handset makers like Nokia and by European regulators.
Services based on DVBH are available in countries such as Italy and Finland, but it's not clear when they will launch elsewhere in Europe due to a lack of wireless airwave licenses.
The No. 2 U.S. mobile service provider Verizon Wireless, a venture of Verizon Communications and Vodafone , began offering services last year using MediaFlo technology, a DVBH rival that was developed by Qualcomm.
Motorola also plans to unveil new television set-top boxes at CES and a device designed to connect desktop computers to services based on WiMax, an emerging wireless technology.
