Can Bluetooth Replace IR in TV Remotes?

AI Thread Summary
Bluetooth technology could theoretically replace infrared (IR) in TV remotes, but current devices do not support Bluetooth signals. The discussion highlights several disadvantages, including higher costs, increased power consumption, and the complexity of Bluetooth implementation compared to IR. Additionally, IR is simpler and cheaper, making it a more practical choice for most remote control applications. The advantages of Bluetooth, such as potential for greater range and data transmission, are overshadowed by these drawbacks. Ultimately, the existing effectiveness of IR raises questions about the necessity of such a transition.

My knowledge in electronics is limited. In general, the television remote use IR for sending signals. I would like to know if the same signals can be transmitted using bluetooth. If so are there any disadvantages in using bluetooth technology in television remote?

Hopefully, a mod will be by to move this to the electrical engineering sub-forum.

The biggest problem with using Bluetooth in a TV / DVD / sound system / VCR(?) remote is that none of these devices receive Bluetooth signals!

If you're asking in a more general sense, as in replacing all of these, I'll leave it as an exercise to the Forumer what advantages and disadvantages Bluetooth might bring. Consider the impacts of:
  • directionality,
  • power consumption,
  • the bandwidth / throughput and how much data actually needs to be sent,
  • how much "congestion" there is in the frequency bands of use,
  • how much the receiver / transmitter / transceiver cost (in bulk), and
  • what licensing fees and regulatory bodies apply.
 
I don't see why not. It'll work. The question is why?! It is more complicated to use BT as you are dealing with microwave, all the protocode, software and all. On top, you might have to deal with FCC when you transmit EM into air.
 
One thing is cost. IR s are lot cheaper than Bluetooth. Also, transmitting IR signals also consume lot less power.
And top off all, why change at all? what's bad about IR ? Do you really want to change the channel of your living room television from your bed-room? :)

Infrared light is also EM wave :-p

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
