MTS stereo surround sound audio encoder IC: This stereo encoder chip dramatically reduced cost and size to allow the integration into consumer electronics products for the first time, thus making RF transmission of MTS stereo and surround sound audio signals from consumer electronics products to stereo television receivers economically possible. CE Labs partnered with Motorola Semiconductor to build the chip with our embedded patented, intellectual properties. The stereo chip is currently used in Radio Shack's new stereo RF modulator and is being integrated into set-top box products such as Dish Network and DirecTV satellite receivers.
