Is there anyway to eliminate the latency on bluetooth?

The latency makes watching movies impossible.

General streaming music etc is fine but video content is always out of sync.

I dont want to use any software to push out the video latency to match the sound either as i stream and watch video content through various players.

Failing a resolution would mean i'd need to go hard wired but i'd rather not if it isnt required.

Video over Bluetooth would be interesting.

What is the hardware you are using?

No im not using video over bluetooth!

The audio runs over bluetooth and the video runs over HDMI.

There is a latency delay in the audio over bluetooth which means the video and audio are out of sync when watching videos.

Bluetooth has latency - im just wanting to know why and if there is anyway to get rid of it?

Of course if audio is connected via cables along with video via HDMI, there is no out of sync issues as the audio isnt delayed.

I also dont understand why we have latency on bluetooth - the playstation control pad is bluetooth (i think) and that ha sno latency.

Latency depends on the codec. Sbc is low latency but sounds awful. MP3 and aac are better sound but massive latency.

Aptx should be good sound and low latency but in my testing with a few receivers from my phone there was just as much bad sync issues.

I just use analog wireless headphones from a cheap day plugged into the tvs optical out when watching at night.

You can't run a signal over the air and over the wire and expect it to be synchronised at the same time.  Apart from there being different processing requirements for the electronics involved which take time, the signal physically travels at different speeds through each medium.

In general over the air will be slower than physical cable.

Is there a reason you are not using the audio through the HDMI connectors - for example, using separate Bluetooth speakers or something?

Nope, air is physically "faster" than cable.

Radio propagation in free air is faster than an electrical signal in a copper cable, , probably by about 50%

I was also including the processing technology required to put the signal into the air.
