Hi,

I never did this before.

I would say you will need two chips

A HDMI transmitter and an analog frontend.

For the HDMI transmitter you can use a silicon image chip
Silicon Image Products - HDMI Transmitters
or NXP
NXP Semiconductors[i=55186]|pp=[t=pfp,i=55186]
or Analog Device
Analog/HDMI/DVI Interfaces | Audio/Video Products | Analog Devices

all of them use digital RGB or YUV data as an input.

So depending on which analog (e.g. CVBS-Video or VGA or ...) you need to select a different analog frontend.
e.g. this one may not be the cheapest, but supports several input formats
