Wireless Surround Sound/Home Cinema Systems

[Mr Olympia]

Are they any good?

I'm after a decent (allbeit not expensive ) home cinema/surround sound system and as I don't really want to run wires everywhere was thinking about getting one with wireless rear speakers.

So anyone know of any half decent ones at a reasonable price?

Cheers.

I'd be interested in this as well

i looked at some of these a while ago, and some with wireless rear speakers seem to need line of sight (infrared?), which for me would be a no go.

im sure they use radio mhz? .. i dont see how infrared can transfer that amount of data tbh so quick?

Fucking great question as I'm in the market too.

Although they are only wireless for the rears (2.4GHz wireless transmission).

Another option is to buy a wireless conversion kit for the rears , something like this

2.4GHz wireless transmission , although they will be struggling to keep up with the HD audio formats (24.5Mbps for blu-ray DTS-HD Master Audio)

I have a setup with wireless rear speakers. It's now old-ish as it doesn't have an optical audio in/out. Sometimes I experience audio lag while playing the PS3, though it can be re-calibrated. I can't hear any loss in quality with the wireless speakers.

There is a transmitter, which you should be prepared to hide as well, needs its own powersupply too. I don't use the center speaker, as I don't have a place for it, but the TV does cover for it. I'm very much into the visual as well, so these are great as they are the same hight as my 42" LCD is on the TV stand, also the back speakers are tall enough not to be covered by for example the sofas armwrests.

So perhaps you should look for something similar, of course with up2date specs.

Has he not got any delay settings in the audio menus of the amp ?

Failing that he may need a HDMI 1.3 compatible system ( display , cables and amp)...

HDMI version 1.3 includes a specification for lip sync capabilities. HDMI 1.3 specifications incorporates an automatic audio syncing, or lip syncing, capability. In a digital television, the video processing usually takes more time than the audio processing. Because of this, synchronization of video and audio can become an issue, if it becomes noticeable to the viewer. This can create an effect that is similar to a badly dubbed movie, where audio and video signals are out of sync. HDMI 1.3 utilizes a method where the audio processing times in the devices can be adjusted automatically to remove errors in lip sync. The 1.3 lip sync correction functionality is needed on the device that creates the lip sync problem, usually a display, which has a lapse between audio/video processing because of the more demanding requirements of video processing, and a device that will correct the lip sync delay. The initial implementations of this will be in a receiver, but this functionality will be in DVD players, and most other CE devices in the future. The reports from manufacturers indicate that this function will be widely implemented and is very popular.

Audio and video synchronization problems occur because video processing is more intensive than audio processing. Because of this, audio is ready for the playback before the video. Without synchronization, what viewers hear won't match what they see on the screen, for example, where the timing of lip movement is off from the words being heard, and this significantly impacts the overall viewing experience. A/V synchronization, also known as lip sync, is maintained by delaying the playback of the audio stream until the video stream has finished processing. The actual delay needed for synchronization will depend upon the type of audio and video signals, and the current video mode.
