***Attention***

According to our experience, the built-in decoders of some Televisions (like LG 43lf5100) only support MPEG-2 encoding method,  thus people can only hear the sound but no pictures showing from the TV programs. Before you purchase a encoder modulator, please check the decoder's specifications or call the manufacture to confirm if the Television supports H.246 or MPEG-4/AVC.
