HDMI to MIPI DSI Converter processes and displays video streams on small screens

Claimed to be the first device to enable HDMI video and audio output to be converted and processed as a MIPI DSI video stream for industrial and consumer small form-factor LCDs, the T358779XBG HDMI to MIPI Display Serial Interface bridge IC has been released by Toshiba.

It reduces memory bandwidth and video processing requirements on the host processor, by providing integrated on-chip support for video processing, video de-interlacing, video scaling and video format conversion. Up-down scaling and colour-space conversion allows output from the application processor to be formatted and scaled to match the display panel’s output resolution and colour format.

The IC supports common 3D video formats and protocols compatible with the HDMI 1.4 standtard at resolutions up to 1920×1200

and refresh rates of 60frame/s. Interface speeds of up to 4Gbit/s to an LCD panel are achieved using four data lanes at a maximum 1Gbit/s/lane link speed.

Multiple audio interfaces including I2S, TDM, S/PDIF and MIPI Serial Low-power Inter-chip Media Bus (SLIMbus) audio formats are supported.  The 80pin device for non-HDMI boards measures 7x7x1mm, with 0.65 mm ball pitch.
