Clarification of Answer by

My apologies, as you had mentioned that neither your laptop nor your
home theater was already equipped with Bluetooth capabilities, I
presumed to provide you with the easiest commercially available
solution instead of restricting my answer to just Bluetooth solutions.
To address your question(s) in the order you asked them:
- Is this feasible:
Yes, it is feasible (but not advisable) to use Bluetooth to stream
audio from a PC to a home theater system, with the understanding that
there will be quality issues
- If feasible are there any commercial solutions available:
Here are the commercially available Bluetooth solutions. Note that,
depending where in the world you are located, they may or may not be
commercially available to you.
Fujitsu has a limited-sale device called the AIRJUKE, which is only
available to customers of their PCs, in Japan:
You most likely are already aware of the USB Bluetooth adapters, such
as the D-Link DBT-120:
Last year, a Bluetooth developer, Impulsesoft, released a reference
design for a Bluetooth Wireless Stereo Adapter:
Unfortunately, to date no manufacturer has used this design in a
commercially available product.
- If feasible and no commerical solutions are available, what is your
idea about building such a solution:
The simplest way to create such a solution yourself, without requiring
electronics development work, is to find a low-cost computer that can
be dedicated to the home theater system, equip it with a Bluetooth
adapter, a stereo sound card, and an MP3 player application, and use
it in a wireless Bluetooth network with your laptop to access and play
the MP3 files stored on your laptop. Any other solution would require
the development of custom firmware and custom electronics for the
Bluetooth-enabled receiver at the home theater end of the connection.
If you are an electronics expert, then you can consider using the
Impulsesoft reference design (they may be willing to sell you a
development kit) along with a basic power and amplifier circuit to
build your own, dedicated device; however, the expense of doing so
would outweigh the cost of buying a low-cost computer with sound and
Bluetooth capabilities. The main part of the expense would be the
licensing expenses related to obtaining the Impulsesoft design.
- What are the possible alternatives:
I reiterate that the best option for streaming audio from a PC to a
home theater, is to use a commercially available Wi-Fi device such as
described in my original answer above. Another viable alternative is
the USB FM transmitter mentioned in snsh-ga's comment below, however
the audio quality will suffer from the conversion to FM.
The Bluetooth protocol is a data protocol, so any Bluetooth solution
will require data-capable devices at both ends. If you are not able to
find a Fujitsu AIRJUKE device available for re-sale, then I strongly
urge you to consider using a Wi-Fi solution for the situation you
described above. If there is a specific reason why the solution must
be Bluetooth, then your options are quite limited.
If this clarification still does not meet your needs, please let me
know exactly why you need a Bluetooth solution so that I can better
understand the context that you need the answer to relate to.
