    YouViews EPG is provided by the internet, not over the air and has been for some number of years.
    I would recommend rebooting your router and then the box. It should re-populate within and no more than an hour.

    Surely it's only the enhanced EPG that comes from the internet with the basic information coming over the air.

    Indeed, the YouView backwards EPG is purely from internet info, the forwards EPG is the standard over the air info augmented (which in some cases actually reduces the quality of the info presented) with internet delivered info. In the absence of an internet connection the forwards EPG will just contain the normal Freeview over the air data.

    Query - since when did YV's EPG use over the air info? And in what format?

    Re Qu 1: Since Day 1.

    Re Qu 2: here, we can read:-

    In Europe, the European Telecommunications Standards Institute (ETSI) published standard ETS 300 707 to standardize the delivery of IPG data over digital television broadcast signals. Listings data for IPGs integrated into digital terrestrial television and radio receivers of the present day is typically sent within each station's MPEG transport stream, or alongside it in a special data stream.

    You contradict yourself my friend -
    "Listings data for IPGs integrated into digital terrestrial television and radio receivers of the present day is typically sent within each station's MPEG transport stream, "

    "OR alongside it in a special data stream."

    Despite Stephens dislike, YouView doesn't use Freeviews EPG and thats a fact.

    Pull your Ethernet cable.

    All past EPG information will instantly disappear.

    What’s keeping the future EPG information alive, then?

    And here are two screenshots of the same current programme display, first without the Ethernet connection, and secondly with :-



    I know how I explain the differences, and indeed why the first presentation isn’t entirely blank.

    But how do you explain it?

    It irks me that the quality of programme information is better from the Freeview EPG than it is from the so called enhanced information from the internet.

    EDIT: Actually that statement is no longer correct. Having played around a little, it appears that the enhanced info does have stuff that used to be missing. Oh dear - red face!

    Roy,
    If you pull your eternet THEN  you will receive a Freeview EPG. This is because YouView is on a list of STBs that are logged to receive it.

    “If you pull your Ethernet THEN  you will receive a Freeview EPG”

    And re Stephen, it was a Disagree, not a Dislike.  But it’s a brave (or foolhardy) person who tries to contradict someone, like Stephen, who has access to the source code  :p

    Ask Piers how it works.

    Why? It’s fully documented:-

    3.9. Platform metadata

    The Platform Main UI application presents a content guide to assist viewers in discovering and selecting content made available through the consumer device. The principle modes of content discovery supported are:
    1. A basic eight-day lookahead Electronic Programme Guide (EPG) derived from locally-received broadcast metadata.
    2. An enhanced EPG for channels from participating Content Providers offering historical schedules and linkages into the on-demand content catalogue.
    3. A browsable catalogue of on-demand content items aggregated from participating Content Providers.
    4. A means of searching the aggregated on-demand catalogue by keyword.

    The last three modes of discovery are supported by Platform metadata served from a centralised Metadata Aggregation System operated by the Platform and accessed by the consumer device over its IP network interface.

    The first mode of discovery ensures that a schedule is available for channels from non-participating Content Providers. It also provides a fallback source of schedule metadata to cover outages in IP network connectivity, and enables the consumer device to operate as a basic DVB receiver–decoder and Digital Video Recorder where it is installed without connection to an IP network.

    (Discovery of content through third-party "portal" applications is also supported by the Platform, but is not considered further here because this mode is independent of the Platform Main UI application and is not achieved through the use of aggregated Platform metadata.)

    Platform metadata is contributed into the centralised Metadata Aggregation System by participating Content Providers via a Platform-defined Business-to-Business metadata contribution technical interface.

    The contributed metadata is transformed by the Metadata Aggregation System into a form that can more easily be consumed by the consumer device and is exposed as a Business-to-Consumer metadata feed in the form of an HTTP-based web service. This corresponds to interface MD4 in the DTG D-Book 7, Part B Section 3.5 and constitutes an implementation-specific metadata delivery interface in that model.

    My emphasis above. The document regrettably does not cover the cessation of excavation by those already in a subterranean location.  :|

    Hm. I'm going to leave it there. But one of you should ask Piers. Hey ho there you go.

    No I'm not, as you've sadly got my goat.
    YouViews main UI application aggregated platform metadata uses an aggregated portal system integrated into its EPG. Do Freeview provide that?  Well, No.

    None of which explains why the OP is having problems with EPG!!

    A good hypothesis is that YouView, trying to get the enhanced metadata that it knew was available for these channels over the internet, encountered a difficulty. And instead of falling back to the OTA EPG, as it would if it knew it had lost its internet connection, it took an ‘internet available but metadata not’ path that led to the ‘NIA’ messages.

    Assuming this was a minor derangement in the running software, in either the router or the box, Visionman’s advice should have proved effective.

    And that the OP has not returned indicates it probably did.

    YouView probably need to investigate the dusty corner case that the software got itself into, possibly one that cannot even be reached by uncorrupted, correctly running, software and decide if it should be doing what it did there, or if it should be falling back to the OTA EPG.

    Which, as it would mask the issue, perhaps it shouldn’t.

    As we are debating fact, not opinion, there really should be no room for goats here.

    But unless the information you think Piers can supply was vouchsafed to you in a private conversation - not impossible, but if that was the case, how could the rest of us know it? - there should be a record of it somewhere, and you could give us a citation.

    The difficulty that I see with your position is that it would require every ‘Sewing Bee in Old 4:3’ marginal Freeview channel to contribute specifically to YouView’s store of metadata.

    Whereas I doubt that they do, and believe they are what YouView above call non-contributing Providers, just about managing to provide the minimum Freeview OTA EPG information, which YouView likewise picks up OTA to populate that line of its EPG.

    If you don't have internet, can't you set a youview box up using the internet at a friend's house and then bring it home to continue to use with full forward in time freeview EPG?
    I tested my box early doors (prior to the NextGen downgrade) as a friend was interested in it as I was telling him how good youview used to be and he didn't have internet, old gen certainly did this, I did a factory reset and pulled the plug to my router. You could even get past the requirement for an internet question during setup back then.
