    The following link is an interesting read on this subject.

    I have been searching the internet for a way to make a computer look like a TV set so that HDCP is not a problem. I have programmes recordings on my Humax box that are unlikely to be broadcast again and are not available for purchase, so I have no qualms about trying to capture these programmes on my computer. I have not had much success so far, but an HDMI Splitter as shown on https://www.youtube.com/watch?v=qAJL8pc85lo might be part of the answer. I can after all record HD programmes on my computer using a TV Capture card which takes a feed directly from the aerial. This method is not as convenient as recording with a Humax box, but the recordings are HD and unencrypted. I am not sure it is worth pursuing this any further as it is turning out to be too time consuming but thank you all for your comments.

    This is possible using a digital modulator and a Freeview PVR. The Digital modulator creates a single channel DVB-T HD channel Mux using the UHF carrier of your choice. the pvr can this tune like any other HD mux. The cheaper ones don’t Dolby Digital so you would have to set the box to output PCM stereo.

    Which Humax PVR do you have ?

    Hi Graham, This sounds promising but how will it help me get my HD recording off my dodgy HDR-1000S in a form that is not encrypted and can be backed-up.

    If you can play them back they can be recorded by a Freeview-PVR.

    Be aware that the recordings may have a much larger filesize using this method than regular freeview HD recordings.

    That was certainly the case when I tried this although with a different make of HDMI modulator. It’s fine for feeding an HDMI signal over coax though in DVB-T2 format.

    Afaik know there are no Digital modulators yet available at a reasonable price that can create a DVB-T2 modulated single channel mux.

    All of them rely on backwards DVB-T compatibility built in to DVB-T2 kit and already available in most TV’s not compatible with DVB-T2 but already DVB-T HD compatible (eg TV’s not Freeview-HD capable like the older HD ready models). All Freeview-HD kit is DVB-T HD capable.

    Not sure wht you mean. I imagine the modulator compresses the video using H264/AVC just like the Freeview-HD channels, The lower bitrate is a result of the enhanced capability of DVB-T2 and stat muxing of channels on the same Mux dynamically sharing the total mux capacity according to the individual channel content,

    Of course a single Mux whether DVB-T or DVB-T2 cannot use stat muxing as there is only 1 channel in the mux.

    This doesn’t mean you cannot compress the recordings later using the much more efficient method of pre-scanning the content from the recording and adjusting the bitrate using VBR to produce a much more efficient file size reduction

    What is two pass encoding?

    Most any Video editing software has two pass vbr output which is of course slower but produces much smaller files than the stat muxing capability within a single mux.

    Humax Freeview+ pvrs include a lot of extra data not required so the file sizes are much larger than is needed. See the CF threads on Hummmy.TV

    This is the modulator I have used – Technomate HDMI modulator.

    It required a DVB-T2 tuner to pick up the signal (HDR-T2 in this case). A DVB-T TV would not tune the channel. You may be correct that it is only because the Freeview HD tuners contain the necessary decoders.

    The spec says T or T2, so it’s probably T.

    Requires a DVB-T or DVB-T2 compatible TV. DVB-T2 kit is backwards compatible so any Humax Freeview-HD pvr should be able to tune the DVB-T single mux. There are known compatibility issues with Dolby Digital/ AAC audio. A manual tune set to DVB-T on the UHF Frequency set on the modulator for the carrier should have found the single channel.

    All DVB-T2 TV’s are compatible. Pretty well all DVB-T TV’s also have HD tuners as most are built to be used including the older HD-Ready designs.

    throughout Europe where DVB-T is still used for HD digital TV. The UK was amongst the first to adopt DVB-T2 for HD.

    The output is DVB-T not DVB-T2.

    t gives a DVB-T output which is sufficient to feed a number of DVB-T capable TVs (via a splitter)

    Provides RF Loop Through 50MHZ~2400MHZ with Power Pass through

    TV Must Be MPEG4 Compatible , All Freeview HD TV’s appear to be, Contact TV Tech if unsure, 4G – LTE (Long Term Evolution) filtering switch ON-OFF

    HD Distribution over an Existing Coax Network, works on DVB-S DVB-C DVB-T DVB T2/S2/

    Perfect for HD Distribution in Pubs , Clubs , Conference Centre’s

    My last two TV’s had mpeg 4 HD tuners but not DVB-T2 capability. Of course in the UK there was no broadcast source. At that time digital modulators cost an arm and a leg.
