At this week’s Mobile World Congress in Barcelona, LG is demonstrating the ability to wirelessly send 4K video from a phone to an Ultra HD television. The company claims the technique, which is ideal for viewing games and other smartphone content on UHD TVs in real time, requires only half the power of other similar approaches. No additional specifics were provided, aside from it using “ubiquitous” Wi-Fi connections.

According to Engadget, the power consumption is the result of “reducing the drain on the phone’s CPU and other hardware, but we’ll have to wait for a hands-on opportunity to learn more about how this works — and to save up enough money to buy one of those Ultra HDTVs.”

“Wireless Ultra HD Transmission technology makes the delivery of smartphone multimedia content to TVs faster and smoother than previous mobile video compression and transfer systems,” notes the LG press release. “With minimal lag and data loss, LG’s next generation mobile feature performs this feat using ubiquitous Wi-Fi connections. During transmission, multimedia content is automatically adjusted to match the receiving TV’s screen resolution, resulting in flawless visuals.”

“Thanks to our innovative Wireless Ultra HD Transmission technology, users can now enjoy their favorite mobile content on today’s most advanced Ultra HD TVs,” said Dr. Jong-seok Park, president and CEO of LG Electronics Mobile Communications. “With the development of this cutting-edge technology, LG again confirms its industry leadership in the area of display and mobile convergence for a truly enjoyable viewing experience.”
