Dear Enginner zone,

  I have a customer that ask an application that need a compact settopbox to connect to TV with HDMI port. This is the specification:


1) switch on tv by HDMI cable when in standby. Is it possibile swith on TV when it is in standby by HDMI CEC bus command?


2) Generate a video message image (static) on HDMI port for alert and warning. Message can alert for specific remenber with elderly peaple.


What can be the chipsets and evaluation boad to use for this application development?

Is there application note that show a block diagram of chipset to use?


I'm sure this application can be done on old PAL tv with SCART connector by specific pin and OSD video generator.


Thank you
