1 Introduction
1.1 Scope
This Guideline applies to Standard DVB-T2 receiver devices forthe Austrian market. This Guideline specifies the minimum requirements forReceiver Devices, which are designated for the reception of terrestrial signalprovided by the ORS group. Compliance to this guideline ensures that the IRD isable to receive, decrypt, decode and transmit the content to a display in anaccurate manner.
The specified Standard DVB-T2 receivershall provide access to both SD and HD signals transmitted over DVB-T and DVB-T2modulation.
It may include access to an internalor external storage mechanism such as a Hard Disk Drive, and should support asophisticated interactive EPG.
This document outlines a set of minimumrequirements for IRD’s (integrated receiver decoder), Conditional AccessModules and TV Sets with an integrated IRD used for receiving the DVB-T2 SD(standard definition) and HD (high definition) television programmingdistributed by the ORS group for the Austrian market.
Exceptions for IRDs, which are integratedin TV Sets, are written explicitly within the affected clause.
Requirements, which apply only to IRDswith PVR or PVR-ready functionality, are explicitly described.
This guideline defines only a minimum setof requirements and is not intended to be a complete specification for IRDs. Itlists the minimum requirements to receive digital audio and/or video in eitherstandard or high definition and/or data services distributed via DigitalTerrestrial Television.

[j1]In order to improve thecompatibility, it should be preferable to use this version
[j2]We don’t have this in our TV sets as usually rooftop aerial are usedfor these tv sets
[j3]Should be possible but we will not deliver any filter directly withthe TV. A software switchable filter is costly. onfirm
[j4]Is “reinstall TV” sufficient to fulfill this requirement?
[j5]Consistency. Please confirm.
[j6]Consistency. Please confirm.
[j7]Our TV is able to transcode but not necessarily at 640 kbps.
[j8]We regret to say that this is not possible for SAMSUNG TVs.
Any user initiated display activityshould always be possible.
[j9]As in the feedback of your first draft.
[j10]There are two separate instance depending on HBBTV browser or openinternet browser. Some of the item are supported in the open internet browserbut not in HBBTV browser. We recommend to propose any service only within theHBBTV framework (standard)
[j11]Reference will need to be updated
[j12]We recommend not to use and stick to HBBTV standard
[j13]We recommend not to use and stick to HBBTV standard
[j14]Same comment
[j15]Not sure which version we have
[j16]We don’t support downloadable DRM. We recommend not to assume thisrequirement.
[j17]For a better receiver compatibility. Please see the new specs for explanations
