This is not regarding any problem, I just wanted to know how this miracle is going on.
I have following HT setup.
Sony KLV50W662F (Smart TV, non-android) to Denon X1200W setup through HDMI ARC cable. Denon is connected with TAGA Harmony 7.1 setup.
Sony TV's Dolby Digital Plus output is set to AUTO mode.
While streaming any preinstalled App on Sony TV (like SonyLIV, Voot, TubiTV, Hungama Play etc.), I am getting following Input Signal on Denon Receiver on DIRECT MODE.
After pressing STATUS button on Denon AVR (Audio mode selected to "DIRECT")
Sig : Dolby D+
fs : 48kHz
Format : 2/0/.0
Input = ARC
Also "DD" and "DIG" symbol is "ON" on the Denon display unit. "PCM" symbol is OFF. Why "PCM" turns OFF, I don't know, if I play any mp3 through pendrive on TV, "DIG" and "PCM" both remain ON on Denon
More to more, if I browse any song streaming website like gaana.com
, spotify.com using VEWD Browser on Sony TV, I am getting Dolby D+ signal too, although these websites are mp3-stereo song sites.
Further TV's preinstalled YOUTUBE APP gives only STEREO SIGNAL, but if browsing YouTube.com on VEWD browser again gives DD+ in 2/0/.0 Format.
As you know all above sites/ app are providing 2.0 stereo signal, then HOW AM I GETTING DOLBY D+ SIGNAL IN 2/0/.0 FORMAT? Is the Sony TV up-scaling Stereo Signal to DD+?
The quality of audio while getting DD+ (2/0/.0) signal is far better than for the same audio I get on Stereo PCM from same Sony TV.
I hope you understand my concern and help me to sort out my query.
