Okay. I got what you mean and want to do. May be the TV that would meet this condition should be more sophisticated as it will have to convert cable broadcast signal which is analog to digital since HDMI's carry digital audio and video signals. But sending the video signal from TV to the receiver is quite opposite of the standard though you only want the audio signal.
By the way, is there any cable company now in the Philippines which transmit digital signals or even HD broadcast? Sana upgrade na nila para ma fully utilzed na dito sa atin ang mga HDTV na binibenta.
Anyway your query I think was already answered by Tonmeister. Regards.....
Yup. According to a A/V shop owner, there's no requirement for that kind of TV feature. Maybe in the future daw, if there is a market drive for the said feature.
OT lang pero, the nearest digital cable is SkyCable. I'm not even sure if you can consider it "digital". Their aim is to minimize illegal connection, so they implemented decoders, and no video/audio improvement. Also I heard that ABS-CBN is conducting a test digital broadcast somewhere in Bulacan. Not sure if it's true.
Yes, Sir Tonmeister also did the same cable "spaghetti" connection.
