IMHO, if Directv is swapping boxes why not replace them with MPEG4-compatible hardware? Converting all channels to MPEG4 will free up much more bandwidth than eliminating the mpg guide.


While I agree that would be a step in the right direction it doesn't really free up any serious bandwidth until the last MPEG2 box goes dark.

Until then they have to continue to use all of that MPEG2 bandwidth...at least for conus. Whether it is being used by 20 million subscribers or 2 million. It stays on until it's off. I suppose they could free up some of the LIL bandwidth if they converted entire markets to MPEG4 but then it becomes a question of are they going to re-purpose that bandwidth or discontinue it? Can it even be re-purposed for anything other than MPEG2 with those transponders or would re-purposing amount to putting new MPEG4/RBS birds into the 101 and 110 slots? And what about Latin America? Does that figure in?

My interpretation was that by eliminating the mpg guide data they are actually freeing up MPEG2 bandwidth to better support their continuing MPEG2 subscriber base (not to mention just ditching obsolete technology and not having to maintain it)...but I could be wrong. If so that indicates the continued existence of MPEG2 for at least a while longer.

-> Yes, it is; one of tp at 119W already converted to A3 format and testing - not sure why, because a few tpns at G3C [DLA/GLA] using the format for HD programming pretty long time.

-> MPG has no relation to video compressions [MPEG-2 or MPEG-4]
If so that indicates the continued existence of MPEG2 for at least a while longer.

So will someone please tell me what MPG actually stands for???
(I assume "PG" is "program guide", no???) I know APG means Advanced Program Guide & am very familiar with those receivers...

Which satellites are currently devoting bandwidth to carrying mpg guide data? Where is there going to be bandwidth freed up by discontinuing it?

I'm pretty sure it isn't the MPEG4 satellites.

Notes:

you messing up technology: video compression vs downlink freqs [Ka vs Ku], modulation: DVB-S2 vs DSS;
satellites doesn't adhere to video compression, as a tube to a liquid inside;
please don't use video compression levels [MPEG-2/-4] when we discuss MPG vs APG;
95W Ku GLA sat transmitting HD [MPEG-4/H.264 compressed video], plus DTV 119W tp24 is testing for same purpose.

Answer:
MPG taking a bandwidth less then 1 Mbps on each of many Ku tpns.

getting rid of the old guide frees up stuff on the backend.
I want CLTV / CLTV HD on direct tv.

if you will do real overview the MPG cease, then it would come to saving bucks for DTV itself - by eliminate equipment and operator-hours
gain scattered bandwidth, the miserable 1 Mbps, on 10-12 tpns doesn't looks as real goal

Someone could calculate total MPG bandwidth for 101W tp27 from a sample below.

Transponder 24 @ 119w is carrying two live MPEG-4 HD channels. Spanish MEGA-HD 405 and TFTw-HD 408.

Not sure what other test channels may be there as well.

Tp.25 is a spotbeam tp.

... Answer:
MPG taking a bandwidth less then 1 Mbps on each of many Ka tpns.


You mean "Ku tpns.?" :)

In case no one has answered you by PM or some other.

MPG - Master Program Guide.

thanks, corrected

No one took the burden to calculate all MPG chunks from tp27 ? Tsk, tsk, tsk ...

I'll add them (after I finish with a late breakfast here :D ), but are those x05XX PIDs the only MPG associated packets transmitted on Ku tp. 27?

No other MPG packets on like PID x0009 on that tp. for instance?

You are right, I'll add these low-numbers PIDs shortly to the picture...


Here is the missing part.
Some notes:
- null packets at 0000
- 0001, 0009, 00b4, 00be are belong to MPG
- 0002, 0003, 0004, 00f9 are sort of management: FW announcements and other things
- 03f2 - DTV TiVo slices.

Actually now past yesterday's dinner, today's breakfast and lunch now and coming up on tonight's dinner. :D

But anyhow after repeatedly counting all the MPG streams comprising PIDs x05XX, x0001, x0009, x00b4, x00be, and the questionable x00f9 packets, the total aggregate stream comes to 1295.14 kbps.

Or ~1.3 mbps.

As was said, virtually nothing in the way of saving transponder bandwidth by turning off the old MPG data related streams, but perhaps a great saving on equipment resources at the broadcast center(s) by its eventual elimination.

Someone (bean-counters ?) added the 1.3 Mbps from a all transponders what carry MPG PIDs and got a whooping amount almost equal to one tpn.
My wonder how it could be utilized after all ?

I got it.

Now time to find someone who could watch the transition and will measure the real gain in bandwidth. ;)

Yes and I'm awaiting the transition so I can finally upgrade my 10 year old receiver. It's funny cause nowadays Directv receivers don't last as long as the older receivers.

They have called several times but i havent answered the phone for fear they would try and get my RCA away from me....... I DONT WANT ONE OF THIER NEWER CRAP IRDs!! (1 or 2 times i have talked to them and they tried to get my BOX off my acct and i explained that I am not interested in HD,etc....... I like my basic IRD and the speed is excellent and i dont wanna lose that) -- I dont care if i dont see the channel data really (I dont see 1/2 of them now anyway!),i have been a customer for about 14 years and i love DTV......... I dont want that to change!

Why dont they just start charging a little bit MORE MONEY to provide the MPG data to older boxs??


DO you have an hd tv? If so, get a h25. It will be better than what you have now, period. Its lightning fast, and easy to use.

The countdown begins, out with old in with the new. Time to start retiring my old receiver.
