am soooooooooo not a techy - but I thought a surround system only worked when watching dvd's ?

edit - av had my surround system for years and will be gutted lol to find out i could have been using it for watching tv also !!!!!!!!! only works for me when watching dvd's???

you can get them to work on the tv as well and shop ass said it did dont see the point in paying out all that money just for dvd's.. thought i'd find some info on the net but can not : (

no - I am still certain a surround system can only be used for watching dvd's or gaming. Been reading ur link and also looked out my manual for mines.

If you have Sky+ or SkyHD you can connect them to your surround system with a digital optical cable providing the surround system has an optical input (the OPs samsung has one, dunno about yours)

well even reading ur link to the system u have bought it doesnt say anything bout listening to ur tv through this

""""Bio Kelp Speaker produces greater detail, crystal clear vocals and a significant decrease in noise and distortion when listening to your favorite music or movie."""""""


I really hope am wrong btw !!!

If your TV can output surround encoded sound via, then you connect its output to the Samsung receiver. The programmes you are watching must be surround sound encoded too (such as from a Sky box supporting DTS but you just connect the Sky box instead). Of course, this is subject top your Samsung receiver having the right connections too.

If you can tell me what connections are on your TV, whether you are using a set top box (such as a Sky box) with surround sound support and what connections are on the back of your Samsung receiver, that would help to determine what you can do.

An example is a Sky+ box that supports Dolby Digital for its programmes. The sound can be fed to a TV which also supports Dolby Digital. The Dolby Digital fed to the TV can be sent to the Samsung receiver (rather than through the TVs speakers). An easier way is to bypass the connection from the Sky+ box to TV but connect it straight to the Samsung receiver, subject to having the correct connections.

Sound from analogue TV broadcasts are not encoded as surround sound, by the way. I don't think Freeview is either but some Sky transmissions are.

mines is a cheap set I bought from Asda years ago for about £50 ! I have sky + but if I thought I could get a better system that would work off my sky then i would go for it.

cheers Deek as I never knew that:thumbsup:

It didnt come with an optical cable, was offered one at a privious store but they guy said it will give surround sound whilst watching the tv but i can not get it to work.

Standard analogue TV cannot produce true surround sound. If your Samsung receiver supports Dolby Pro Logic (which is an old standard) then it can convert your stereo TV signals to a pseudo 5.1 surround sound but it is nowhere close enough to the quality of Dolby DTS that is encoded with some SKy transmissions. As Dolby Prologive takes an analogue signal, the guy at the store did not really know what he was talking about or he was vague with his description of what the TV source feed was.

Of course, just a digital optical cable from your sky+ to your nice new surround system and you're laughin! Just check that it has an optical digital input. Some poor ones ARE only able to play your dvds in surround as they have no auxilliary inputs.

It may not matter if the DVD player decodes the Dolby signals already and output them as analogue via auxilliary connections. The Dolby decoding can be done via the DVD player and through analogue speakers OR send via optical transmission as a digitally encoded format for a separate receiver/amplifier to decode them (and convert them back to analogue) and out to speakers. This is why we need to know the connections to be able to formulate a correct assessment rather than conjecturing ideas (albeit most of the ideas given are sound, pardon the pun).

I'm just saying if she wants surround from her sky/cable then she needs to have digital out from them and digital in on her surround system.

Yep that is absolutely correct providing the receiver can decode the signal that Sky produces which I believe is Dolby Digital. If the decoder supports DTS and not Dolby Digital then it cannot decode it or vice versa - ie. DTS cannot be decoded by Dolby Digital receivers.

have you got sky+ or hd? or v+?
#16
ha all this has gone over my head. Havent got sky got bt vision. Ive looked on the back of the dvd unit that came with the surround and it doesnt have an optical outlet as far as i can see. it only has one lead connecting the kit to the tv.
Would i be able to return this item to the store as i was told it would work?

i think the op is allready confused and that sort of info will totally baffle her i could be wrong though,, shes an optical away from having surround sound no optical no surround :thumbsup:


However, an optical cable may not work either so the advice could be wrong. Only through exact terminology can we get things right (see my previous post regarding DTS/Dolby Digital).

yes, ive checked spec on OPs Samsung receiver and it does have a digital/optical input so now all she needs is an output on her digital box whether it be Sky+/SkyHD/V+

That's enough information to say that you will NOT be able to receive true surround sound from the TV only. Analogue TV uses NICAM stereo and I think Freeview does too. To convert NICAM stereo to surround sound require analogue cables and NOT optical cables because Pro Logic is a process of splitting standard analogue stereo to 5.1 sound (and it's a pseudo way of doing it). The guy at the store has almost certainly advised you wrongly. As I said earlier, get the terminology wrong and this leads to wrong advice and inappropriate expense.

Does it support the Dolby Digital encoding of Sky transmissions? If it does then it will be fine for SKy but the OP mentions that Sky or BT Vision isn't being used. Not sure about other set top boxes though.

If you are not using a set top box you won't be able to receive true surround sound from your TV. That is the bottom line. I can go on explaining the technicalities but you have been missold. Standard TV transmissions are NOT broadcasted in surround sound. Sky channels are (using Dolby Digital) and if your Samsung receiver can handle Dolby Digital then it is possible. If your Samsung Receiver handles DTS but NOT Dolby Digital then that will not work with Sky.

Freeview boxes are also broadcasted in stereo so they won't be able to produce true surround sound.

DVDs are encoded in either Dolby Digital or DTS or both. That is why you can receive true surround sound from DVD players.

If any receiver has a optical/digital INPUT then its a safe bet that it will decode DD from Sky. The OP DOES say she has BT vision.

OP, is it a BT vision V box?

I have a tv and a bt vison box which is like a sky plus box, im sorry i cant quite understand it all and if im sounding dumb. do i connect the surround sound box/dvd player to the tv or the bt vision box?

Ah BT Vision! That might work depending if the receiver can decode the signal.
#27
A website I have seen says BT Vision box does support surround sound BUT the transmissions are in stereo. I cannot verify this but if this is the case, an optical cable would still only produce stereo sound.

This site http://www.radioandtelly.co.uk/btvisionfaq.html says BT Vision transmissions are in stereo. This site directly from BT also confirms it http://bt.custhelp.com/cgi-bin/bt.cfg/php/enduser/cci/bt_adp.php?p_sid=NVgFpL8j&cat_lvl1=348&cat_lvl2=1154&p_cv=2.1154&p_cats=348,1154&p_faqid=9570

Therefore, despite an optical out socket on your BT Vision box you will still only receive surround soundfrom your Samsung receiver. Deek mentioned a V box but I suspect that the transmissions are still in stereo.
#29
the porter
according to the spec of the ops unit it doesnt have an optical anyway so i would of thought that was then end of it


Possibly but surround sound can be sent via coaxial electrical as well as TOSLink optical but as BT's site confirms that transmissions are broadcasted in stereo, that is the nail in the coffin.

Tracey, your samsung may or may not have an optical digital input. The spec on the samsung sight says it doesn,t http://www.samsung.com/hk_en/consumer/tv-av/home-theater/51-home-theatre-set/HT-Z120T/XSH/index.idx?pagetype=prd_detail&tab=spec&fullspec=F
However this site says it does http://www.dealtime.co.uk/xPF-Samsung-Samsung-HT-Z-120-T

Look on the back of your samsung unit and see if it has a socket like this (digital) http://img.tomshardware.com/us/2004/06/21/terratec/firewire_6.jpg

If it doesn't them I'm afraid that's your lot!

Right guess its going back it doesnt have that socket was told this would work. damn them!! will have to have a shop around for one that will work woth my tv and bt vison.

Even if it had the sockets it would be a futile exercise. BT's website specifically says BT Vision programmes are transmitted in stereo only (despite the optical out). Several people have mentioned that it would be futile (all for differering reasons) although one (the salesman) seems to be convinced otherwise.

OK you're not dumb, it's just that I develop software CODECs for TV and video industries. I will explain via bulletpoints:

- Stereo uses two channels for sound - left and right.
- Dolby Pro Logic can split stereo sound into 5.1 sound (that's front left and front right, side or rear left/side or rear right, a centre and a subwoofer). However this is not true surround sound because a processor guesses from the stereo signals whether to move the signal to rear speakers or front speakers or centre speakers.
- True surround has separate signals for 5.1 sound (or more). It has signals for front left, front right, centre, etc
- True surround is in digital format and a processor has to "format" it to the right signal. There are different formats such as DTS, Dolby Digital, Dolby Digital EX, etc, etc, and so on and so forth. This needs to be converted back to analogue (because sound waves are analogue) before being sent to speakers. Now, the DVD player may have the processor to convert the digital sound to analogue and send it straight to speakers but if it doesn't then a receiver/amplifier needs to do the job separately.

Basically, sound is analogue and digital signals need to be converted to an analogue format of which there are various forms. The digital signals can be sent by electrical cables (usually coax) or digital cables (such as HDMI or TOSLink optical).

It is a wide topic and many consumers might know what an optical signal is or what surround sound is but try asking the salesman how the sound is sampled and whether it can subdivide the soundwaves to 92 kHz/s - that always makes me laugh listening to the ridiculous responses (such as well, it can do partial sound sampling - whatever that means).

You need to connect the audio out from your TV to the audio in on the back of your drive. Refer to page 21 of the user manual.
[LEFT]1. Connect AUX IN (Audio) on the Home Cinema to the Audio Out of the external Analogue
component.
• Be sure to match connector colours.
2. Press the AUX button on the remote control to select AUX input.
• You can also use the FUNCTION button on the main unit.
The mode switches as follows :[/LEFT]
USB➞FM➞ DVD/CD ➞ AUX
