A timing controller of a display set is integrated with an encoder for transport of analog signals between a display controller and source drivers of the display panel. The timing controller and integrated encoder are within an integrated circuit and are part of a chipset. The integrated circuit is located immediately after the SoC of a display set or is integrated within the SoC. A video signal sent to the timing controller chip is unpacked into sample values which are permuted into vectors of samples, one vector per encoder. Each vector is converted to analog, encoded and the analog levels are sent to the source drivers which decode into analog samples. Or, each digital vector is encoded and then converted to analog. A line buffer uses a memory to present a row of pixel information to the encoders. A mobile telephone has an integrated TCON with SSVT transmitter.
