eARC這種常用的行銷話術, 常用於被吹噓...
實際上還得看電視怎麼處理訊號..
我不懂為什麼SONY BRAVIA一直沒有把這塊做好..
When eARC mode is enabled, the resolution of the linear PCM signal is limited to protect the content.
For example, the linear PCM signal frequency and number of bits of the HDMI device are limited to 48 kHz 16-bit, even if the resolution of the signal can be output in 192 kHz 16-bit.
NOTE: For ARC mode, there are no limitations on signals from HDMI devices because the resolution can be limited at TV internal processing.
For eARC mode, the resolution of signals from HDMI devices are limited because there is no internal signal processing in the TV.
passthrough:
7.1ch LPCM：32/44.1/48 kHz 16bit
Dolby Digital
Dolby Digital Plus
DTS
Dolby TrueHD
DTS-HD MA
Dolby Atmos
DTS：X Master Audio
MPEG2 - AAC/MPEG4 - AAC
你把它鎖死在16b/48KHz是甚麼意思???(如果去接電腦去讀EDID)
那超出這個範圍就會出現幾種情況..
1. 假設訊號被re-encoding, 那應該會被接受bitstream..
2. 直接resample
3. 直接回報無法支持..
你AVR/Soundbar的eARC做得再怎麼好有什甚麼用???
已經那麼多年了, 是SoC那邊問題還是SONY特意鎖死??
搞得我寧願放棄VRR, 也不要因為eARC變得半殘..
