Kross STB digital audio out, problems - help please |
|
|
Hi all,
finally bit the bullet and got myself a $79 Kross SD STB from woolies.
im well aware that u get what u pay for so i woudlnt be surprised if
thats where my problem lies.
Ive got the digital audio RCA out connected to by denon A/V receiver.
When i select audio stream 2/2 on any channel that has it my audio goes
to crap. sounds like its breaking up. ie, get a small perion of audio
then a small period of silence. each lasting for a few hundred
milliseconds id say.
The RCA cable ive used is just a cheap RCA cable used to composite video.
So im quite unsure as where the problem is. Is it the Kross box or the
cable? Ive tried a different cable and same problem.
any help, hints of suggestions would really be appreciated from those in
the know.
thanks
david
ps. analogue audio out for audio steam 1/2 is fine. when selecting
stream 2/2 there is no analogue audio output.

Are you going in to a digital input on the reciever? What Model of
Denon is the reciever?
Can you please give a bit more detailregarding teh 1/2 and 2/2 thing?
picture is perfect. reported signal strean is around the 90% mark. |
yes, definetly going into the digital input. receiver is a denon 1804.
never used to RCA digital input before, always just used optical. the
STB doesnt have optical out.
im new to the whole digital tv thing. from my limited understanding one
is an mpeg audio stream (1/2) and the other is a DD stream (2/2).
what i noticed as well is when selecting 1/2 the analogue audio worked
fine (as did the digital to the receiver). selecting 2/2 produced no
analogue audio out and the problem i originally described. i guess it
could be described as a stutter almost. |

Audio 2/2 is Dolby Digital 2.0 - stay with audio 1/2 (Musicam) and all will
be fine.

What exactly is Musicam?
My understanding is that the DD 2.0 audio track is higher quality that
the first track. If thats the case id like it to work.
thanks for the response :)

MUSICAM is an acronym for:
Masking Pattern Universal Sub-band Integrated Coding And Multiplexing.
In simplest terms it's a type of CDMA-ish MPEG2 audio. It's used in the
Eureka 147 DAB radio as well.
I personally have the facility to switch audio on two of my STBs but more
often than not the level is always lower than the main sound and setting
channels to it is all fine and well until one comes across a station not
having it available (SBS for instance) and then there is a mad dash for the
volume control.
I can't see any advantage in using it (Audio 2/2) unless something is DD
5.1, which happens on very, very rare occasions on ABC SD. Also rare on the
HD channels these days too.
There was also a mis-information at the start that the MPEG 256k (Audio 1/2)
streams were frequency limited to an upper limit of 15kHz, but this isn't
the case. They are full frequency just like the DD2.0, so I can see no
advantage in using it as long as your system is capable of DPL/DPLII(x) as
the end effect is identical.
The only thing I have personally noticed is that when audio breaks on
Musicam it squeals and in DD is just mutes. Other than that there is no
reason I can fathom to bother with it, especially if your signal quality is
marginal.
If you insist on hearing it - it sounds from what you've told us that you
may need to look at your signal strength and quality issues. FWIW the Audio
2/2 here is intermittent too because I run off variable internal antennae on
all 3 of my digital receptions and it really depends on the atmosphere
etc...

Thanks for the good explanation :)
Signal strength is report at being around the 90% mark, but i dont think
im going to waste anymore time trying to get the DD stream.
