No 5.1 Audio in HD channels

[Jaymin]

So you technically should hear one set of sound from left front and left rear together. The second set of sound from right front and right rear.

5.1 means whatever is meant from a particular speaker comes out of that speaker and not a set of speakers unless meant like that.

Was i posting in Chinese/Russian/Hebrew till now?

As if i didnt knew all this. U r not getting my point as well.

When i say a sound meant for coming from left back, comes ONLY from left back.
Right back, comes ONLY from right back.
Front left comes ONLY from front left.
And front right, comes ONLY from front right.....with the woofer giving bass.

Isnt that CLEAR ENOUGH? Oh, btw, do u know that in the above, when i said "Right back, Left back, Front left, Front right, i referred to a 5.1 channel speaker system?

I thought this post by me, few weeks back, was clear enuf I have experienced this myself......when u hear someone calling out from behind in a movie, that sound precisely comes from behind, and only from left OR right, whichever side that sound came! Listening to HD Music channels....same experience! Please dont tell me that i am not able to pick up the sound from the front speaker at that same time. I have watched enuf of SD stuff to be able to make out when its just an upscaled 5.1, as against real 5.1. And thats the reason why i m totally amazed as to how cud u guys say that the sound isnt 5.1!

If this is not 5.1, then what actually is?

Coming to ur question of cable.....i m not using the stereo cable. Its the Component Cable, which does carry 5.1 channel sound, but not Dolby.

VIDEOCON only provides stereo sound. Your stb is sending only stereo. not 5.1Component is stereo audio not 5.1btw also the "upscaled" terminology limits to video. What ddo you mean by upscaled 5.1?

 

[Jaymin]

I thought of shortening the term "Dithering of frequencies to make u feel its all around u" to upscaling, which seems logical enuf!And u still didnt tell me how did i got sounds from individual speakers then! In fact when someone walked out a scene saying something, the sound actually moved in that direction from front speaker to back speaker, and either left to right or right to left, or whatever......

 

[rajivkrishnan]

Well consider this definition if you may: Upscaling affects the original source is "enhanced" (usually requires a video processor to achieve) and is prevalent in modern televisions/ computer monitors/stbs and such video devices.The sound on the other hand is not enhanced. all it does is routing thru a particular channel. usually speakers are (as u rightly put it) GIGO. But there are instances when a fair amount of channeling can be done by the speakers in question.the televisions on the other hand are definitely competent to send a particular set of frequencies through a certain directed speaker onboard. Virtual Surround if you may is what this is usually called and marketed as. There is no enhancement.So all i can say is what you are experiencing is not any sort of 5.1. anything that is happening is quite plainly put "simulated"

 

[Jaymin]

But u have already said that if a sound coming from left back, comes only from left back, and so on, then that is real 5.1?

 

[rajivkrishnan]

what i mean is that should be 5.1 from the source to speaker to be graded true 5.1. something like video should be 1080i all through from shoot to delivery to be regarded full HD right? No manipulation anywhere later. Please do take some time out to visit an audio showroom to understand what i am talking about.

 

[Jaymin]

I have visited quite a few of them.And still, i m failing to understand ur logic here......sound that shud come from left back, comes only from left back - this will be considered true 5.1, only if u have been told by someone that it is 5.1? So is it that when theres a car placed in front of u, and someone says it is a car, only then u believe it is a car?I mean whats the difference between real 5.1, and the manipulated 5.1 then? In real 5.1 u get a sound from left back and all coming from that respective satellite. And in the alleged manipulated 5.1 too, the same thing happens! Whats the difference then?

 

[rajivkrishnan]

no it is not the same. In the real case it is a digital signal which actually goes through a decoder (All the sound that is meant from a particular channel is correctly routed.).

In your case, it is a sterero input is being worked out into 5 tweeters.

For an example most dialogues are usually center channel routed in the real. Are you sure you get that? I doubt. I am sure the left front and the right front speakers in your case will also boom.

Let me put this more clearly. a cricket commentary should be out from the center speaker. and the stadium effects from the other four channels.

Your mentions of say a cycle passing through the back (a case you mention) it is anyway a squeak. Quite the levels which should be channeled through your back tweeters.

If you still want to believe the "car" is in front of ya. I can help you bud

Cheerio.

I havent noticed that while watching the matches. But while watching movies, songs on HD channels, i can clearly notice the difference. The D2h Movie channel always used to air Hungama. Now yesterday, i saw that on Zee Cinema HD. There were lots of background sounds, which were not audible in the D2h movie channel, but were audible in Zee Cinema HD. And these sounds that were missing in the SD channel, were in fact the background sounds. Dont think of Background score, coz i dont mean to say that. Its the sounds. These came only from the back speakers.If what u said was to be believed, then i shudnt have been able to notice these differences. Even the SD channel shud have carried the same sounds as the HD channel.And no its not just a cycle passing. If in a scene, there is a road running from right front to left back, then u can actually hear the sound of vehicles starting loud from the right front speaker, and it goes on reducing, and eventually, it goes off, and in that order only, it increases in the left back, until the vehicle eventually goes off the scene.Someone is speaking in the background, that sound comes only in that dedicated back satellite, and as that person comes in the scene, the sound gradually moves into that front speaker.Just embarassing that i have to explain someone like u, in so much detail! U seem to have good knowledge of this stuff, but still u r making me explain the things in such detail! Havent u experienced it urself, ever?

pff.. "dedicated" back satellite. right correct. I am really sorry to have disturbed you over all these weeks and this weekend.Cheerio means a goodwill parting wish on this count.
