MHEG5 question

muchos04

Hi guys,

With all of this chat in another thread about MHEG5 tests on the new DTT platform....will this feature be disable in a combo receiver i.e. you won't be able to use any interactive features that for example RTE might promote???

Yes, if they dont have MHEG5 obviously.

Don't freeview have the "red button" streams as channels (high up), as per the streams you can tune in on satellite? I don't really know the technology, so will that be different with saorview?

slegs

Channels that are boradcast behind a red button type service would be tuneable through channel editors much like they are on UK freesat channels. CAnt see any on this being a big issue compared to the pluses of having a single guide for DTT and UK FTA.

Only any actual video is watchable as unlisted channel(s). The text, still images and menu is in an MHEG5 stream and only accessible to receiver with MHEG5 support.

Due to number of Radio Channels and number of TV channels it's unlikely to have more than one video stream (could have 2 to 6 low resolutions framed in one channel as on Sky), and possibly may not have any video stream. Unlike satellite the DTT is very limited in space, about 25Mbps compared to about 2000Mbps total across all transponders on one slot.

Thanks Guys,

Can this be incorporated into a Combo receiver in the future?

If they get a licence for MHEG5 and have the desire to upgrade to include it which is unlikely. There may end being a combo specifically for the Irish market that is MHEG5 compliant but I havent seen it yet.

Thanks again Slegs,

I always appreciate your informative responses. Let me know if you here any updates!

There is the Triax ST-HD527CI combo, which has MHEG5 listed as a feature on the box, but I couldn't get it to work when I tried it out in Power City.
It also states it's a "UK & Ireland" version, so they have this market in mind.
I'd be interested if to hear if anyone has any luck with this?

Did you try it out over the past week or so? There are problems with MHEG services on the DTT trial at the moment so it may not be the box that was at fault.

I have yet to see a combo box with MHEG5. Even the Hyundai combo box used in NZ.

Its not in the specs.

Was it actually on the box as a sticker (probably added by a retailer who didnt know what it was).

Any such box should it appear in the future would most likely be Linux based and will have to specifically gunthered.

Almost all use a form of Linux, just some not accessible

The problem is that
1) Market for Combo boxes is much smaller % in most countries than potentially in Ireland
2) Openview (Not open, similar to Sky's Interactive), MHP and MHEG5 are nearly mutually exclusive as each is a licence cost. The Freesat & Freeview do use MHEG, but seems not the same version as RTENL specifies, though Wikipedia claims it is. The cheaper boxes won't bother with any extra Interactive service.

So a box with MHEG5 and BBC's flavor of MHEG for Freesat as a Combo is a very small market. Even a UK DVB-t2 + DVB-s2 HD Combo is a small market. Such a box will work here, but may not have MHEG5?

Can anyone confirm if Saorview MHEG5 works on a new DVB-t2 HD UK box? (I know the video, audio and now/next will work)?

Also in 2011 you can look for a box with IPTV, HD Freeview and HD Freesat that supports Canvas

MHEG-5 UK Profile, version 1.06 (from 2003) is the standard used in Ireland, UK (freeview & freesat), Hong Kong, Australia and New Zealand. The DTT Ireland website gets it slightly wrong.

The RTE free to air DTT services will use an MPEG 4 compression standard and MHEG 5 (V6) middleware MPEG 4 is different to the MPEG 2 compression standard used in the UK. Retailers should note that televisions with MPEG 2 tuners only, will not pick up the Irish DTT service, when it develops.

Extra extensions (high definition graphics, international character sets and return channel functionality) were are added via D-Book 6.0 (these are also part of the Australian spec) and are also there in the new ETSI MHEG standard.

The Freeview MHEG-5 requirements stipulate compliance to the UK MHEG-5 1.06 standards with the HD (High Definition) and IC (return path) extensions (DTG D-Book 6.0). In addition some Australian specific requirements such as support for Maori character set and the use of the Electronic Programme Guide (EPG) remote control key are also required.
