Iam a beginner trying to learn about HDMI specification, CEC Protocol and HDMI-CEC compliant switches. I have a few doubts on these topics. Basically, iam trying to understand the HDMI Specification version 1.3 also. I shall be greatly happy if any one can answer my queries. 1. Will the CEC (consumer electronics control) protocol inside a HDMI Source and HDMI Sink be the same? 2. Are HDMI switches which support CEC protocol available commercially? I have seen some HDMI switch products which come with a separate remote. In cases where 2 HDMI sources are routed via a 2x1 HDMI switch (with CEC and a remote) to a HDTV, do I need a separate remote to operate my TV and a separate one to operate my HDMI switch? If yes, then is it not that the advantage of HDMI is being lost? 3. Do we have cases like a HDMI switch and A/V receiver both supporting CEC protocol and both being mounted inside a HDTV? If yes, then will a single remote be used to control the basic operations of a TV as well as the basic switch functionalities (of selecting either one of the 2 sources being connected to the HDMI switch)? 4. Will the HDMI switch do any control function? To be more specific say I have 2 HDMI sources (Set top box and DVD player), one 2x1 HDMI switch and one HDTV. All are just connected without any signal transaction (ie., all 3 three devices are in power-down mode). Is it possible for me to turn on the DVD player, HDMI switch and TV using the single remote? 5. The HDMI offers many features like one touch play, one-touch record, etc… If I want a one touch play feature is it enough if I press one touch play button in the remote? Will the DVD player be powered on by itself? 6. Consider a display device like TV is present. It is connected to one HDMI source say Set-top box (STB) in one HDMI port and a HDMI switch in another HDMI port (The HDMI switch is assumed to support CEC protocol). The EDID information to both the sources will be stored in the VSDB part of the TV(root sink device). a. Now, if I connect a DVD player to the HDMI switch how will the EDID information to the DVD player be assigned? Will it be got from the EDID of the switch or the EDID of the TV? b. Will the DVD player know all the manufacturer configuration details of both the TV and the switch by means of the EDID information transmitted via the DDC channel? c. Also how will the physical and logical addresses be assigned to the DVD player?
