AC4 Audio and ATSC 3.0
There is a new digital TV standard coming. It is called ATSC 3.0 or NextGen Tv. ATSC 3.0 uses AC4 audio as its codec.
Most TV markets have at least one ATSC 3.0 channel. Where I live it is 125.11 PBS, Greenville, NC. I have a tuner capable of ATSC 3.0 and I supposedly have a TV capable of AC4 audio. So everything should be hunky dory, right? Wrong.
But John, it says right in the LG specs for this specific TV that it supports AC4 audio. What gives?
Here is what the manual says:
Kick a Technical Writer In The Balls
Let me say this: There is a world of FUCKING difference between:
- Supported Codec: AC4
- The AC4 codec is only fucking supported when using a wired speaker with Dolby ATMOS support is connected via HDMI ARC and Digital Output is set to “Pass Through”.
The technical writer who wrote, “Supported Codec: AC4” needs a swift kick directly to the balls. In the event they identify as a woman they need a swift kick to the __________. “insert politically correct genital area terms here”.
Do you feel me? You need a sound bar that supports Dolby ATMOS with an HDMI ARC connection and a TV that has an HDMI ARC port. My TV has the HDMI ARC but my sound bar is ancient.
I bought this TV knowing I would need the AC4 codec one day. Brand new TV, brand new tuner with ATSC 3.0 and still no sound.
I’m a geek with a Tech Blog and this is happening to me. How do you think you are going to make out when its time for you to take this leap?
I am only trying to get picture and sound from a TV station that is available over the air and received with an antenna. Right now I can get the picture, but no sound. And oh by the way I only get the picture because I have that ATSC 3.0 tuner that I bought.
How does this make any sense? My TV doesn’t really support AC4. Not without a wired source capable of decoding it. Any old HDMI ARC sound bar will NOT work.
As an early adopter of ATSC 3.0 and AC4 audio all I can say is I hope they straighten this out.
