Researchers in Germany have combined the new mobile radio standard LTE-Advanced with a video coding technique to enable 3-D films on cell phones.
Researchers at the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut, HHI in Berlin, said a survey by BITKOM found that 10 million people surf the internet with their cell phones in Germany – and there is another hype that is unbroken: 3-D films. The researchers have been able to put both of them together so people can experience mobile internet in three dimensions.
They have come up with a special compression technique for films in especially good high-resolution HD quality. It computes the films down to low data rates while maintaining quality: H.264/AVC. “What the H.246/AVC video format is to high-definition films, the Multiview Video Coding (MVC) is to 3-D films,” the researchers said.
HHI scientist Thomas Schierl said: “MVC is used to pack together the two images needed for the stereoscopic 3-D effect to measurably reduce the film’s bit rate.” This technique can be used to reduce the size of 3-D films as much as 40 per cent. This meant that mobile users can quickly receive quality 3-D films in connection with the new 3G-LTE mobile radio standard.
Thomas Wirth, another scientist at the HHI, explains further: “The 2-D and 3-D bit streams divided up by MVC can be prioritized for each user at the air interface to support different services, thus opening up a completely new field for business models.”
The researchers will be presenting their solution from February 14 to 17 in Hall 2, Stand E41 at the Mobile World Congress in Barcelona.
