    I suppose nothing will happen. Producers will try to sell as many products as possible and not add details to new standards. In addition, the aging process, which is deliberately planned in such receivers, must be taken into account. Perhaps the material crisis as a result of COVID (and the US / China technology war) will verify the actions of the electronics industry, but it will not happen soon.

    There is more and more talk about the growing demand for monitors with loudspeaker tracks as an actuator for a set-top box or home theater / receiver. This is because there is a sharp decline in interest in "FTA Linear TV" in terrestrial mode. And making the control and switching of the monitor from the decoder / cinema / receiver signal is child's play. Then even the remote control for the "telemonitor" will not be needed, and mostly people do not like the option of multiple pilots.

    I do not think any manufacturer added a module or issued a software update for older receivers. It is not in his interest. He will make such an additional module and earn, for example, $ 10 or $ 20 on it. In the absence of a module, there is a chance that the customer will buy a new receiver and the manufacturer will earn $ 1,000 or $ 2,000. The bill is simple. And since there will be more electro-waste and more CO2, who cares there. Only profit counts. The blame for increasing CO2 will be placed on coal and diesels, because the electronics do not smoke.

    The module will not be simple either because it must have a new head with an antenna input, i.e. practically a receiver / adapter.

    Good morning
    Nothing new in this topic?

    I was thinking about uploading another software from another PANASONIC TV
    TVs from 2014 do not support HEVC, but I found a model from 2014 TX-55AX900E which HEVC has and from 2015 TX-43CX750E also has, these are 4K TVs, and mine found HEVC but there is only the sound of the image, the 2014 model TX-47AS750E and such versions of the software and such processors are given below.
    Visually identical softs in terms of functions and operation, but I am afraid if it is possible and how to restore the old soft in case of failure, I have nothing to test, other motherboards, only one TV and there is no description anywhere and whether it would be able to do it to do this?

    TX-47AS750E Dual-Core Plus 2014 P145_3114.zip MY TV
    TX-55AX900E Quad-Core Pro5 2014 P146_3054_G102.zip
    TX-43CX750E Quad-Core Pro 2015 P153_3252_N025.zip

    Of course, they are packed, and the soft version is SDDL.SEC, what to unpack and see what's there?

    There is a difference in processors, but my old single-core IBM T43 laptop on Linux HEVC plays, so I figured,
    TX-47AS750E Dual-Core Plus would also play?

    I thought about removing the codec from TX-55AX900E Quad-Core Pro5 2014r P146_3054_G102.zip and adding it to
    TX-47AS750E Dual-Core Plus 2014 P145_3114.zip, is it in any way possible?
    Any suggestions, gentlemen or total linden?

    Ideally, you should pull out a parameter set from the codec's specifications. Remember that in the West it is quite common to use 64QAM with a different FEC and different GI. In Poland, however, 256QAM / 32K FEC, most often 2/3 and GI 1/16, are in force. Therefore, a lot of receivers with a loaded HEVC codec but supporting only up to 64QAM and even 32k will not receive it. And then you only have sound without picture.
    I suppose that soft made before 2019 will not work.

    On my LG 55lb674v-zb nothing worked either in terms of the new channels and the test one. I changed the country of transmission: Czech Republic or Germany and it works. I did not check the others. Apparently, we do not have support for some receivers. Maybe it will be useful to someone.

    So you did the installations again and changed the country?
    and that was enough? it would be brilliant if it worked.

    If there is no picture but it plays sound and EPG, it means that the TV set has a newer T2 head but the processor or software cannot decode HEVC video. For some of these TVs, the manufacturer has created software updates that add support for HEVC decoding, so it's worth checking and updating. If there is no image on the latest software, it remains to buy a decoder or replace the TV. The solution could also be a CI module that converts HEVC video to MPEG4. Unfortunately, it seems that nobody came up with the idea to produce such modules and put them on sale. In the past, you could buy a CI module that converts MPEG4 video to MPEG2 because many TV sets only supported MPEG2 and in Poland only MPEG4 worked.

    the cost of a module that would do a recode from h265 to h264 would exceed the value of the TV

    and by any chance in televisions there is no hardware codec? I doubt it is in the software

    And they won't.

    Even if they existed, it would not work for him, the Ci + module never decodes the image, decodes the stream, and the image of the device in which it is mounted, i.e. it must support a given encoding standard.
    It was always cheaper to buy a DVB-T2 HEVC tuner.


    @eewaldi, maybe it would not be that expensive, but it would be hard to find a TV that supports high bitrates after such 1: 1 transcoding. Remember that the use of HEVC allows you to reduce them at least 2 to 3x in relation to the identical MPEG-4 (AVC / H.264) encoded image that its TV probably supports. From 36-40Mbps it would suddenly become 80-120Mbps, which is rather beyond the capabilities of the hardware decoder on the TV.
    The usual speed for MPEG-4 (AVC / H.264) encoding in terrestrial DVB-T was around 20-25Mbps and for HEVC around 40Mbps.

    I have read and I know that there is nothing to buy this German freenet PCMcia, it's a pity. My tv is LG 42LM640S-ZA which is not even on the Lg website.

    I have a test channel, I only receive the sound with the LG logo.

    This freenet tested someone when changing the settings to Germany?

    The module gives nothing, it does not decode the image, but the encoded stream decodes which then tv decodes. There is no codec support on such an old TV, so there will be no picture.

    From the given set of countries, the Czech Republic has DVB-T2 the longest and in the same modulation standard as ours, i.e. 256QAM 32k AC3
    The message about missing CI module proves that the receiver correctly detects programs encoded in MUX4. But it also means that the receiver should receive Events24 from MUX 4go.

    And what is this strange place on the border with DE that there is only MUX1?

    Słubice the bearing of the antenna on Jemiołów I have all the muxs theoretically, maybe the block is covered or the antenna is too weak Mux 2 and Mux 3 quality 0 and signal strength from 40-70% Mux1 has a similar signal strength but quality 100% ... sometimes I have programs with mux2 or mux 3 ....

    The events of 24 I perceive only sound. It is a pity that these radio stations were only caught in the country called --- I can't listen to it because I miss the CI module ...

    In the selected country, the Czech Republic, I only have sound on all channels .. The only countries with pictures are Poland and this ---.

    I have a Sony bought in 2014, and hevc is flying. But I would like a CI supply for the old LG from 2010, and somehow it was possible once. For plasma grundig from 2006, with an analog tuner I added a Ci card to digital TV, it installed, a new digital TV tab appeared in the menu and it worked.

    What that digital TV worked if it is not HEVC encoded and supports old TV with DVB-T.
    You probably write about Polish TV that is completely liquidated and will no longer be there.

    Note that to work with the new HEVC system and support on older TV you MUST have it with HEVC or buy a tuner. No CI cards will spell it to work, no such cards.

    The first plasmas did not have a digital tuner, there was only UHF, and the add-on included the digital TV DVB-T format. And the TV was from such years that there was still no standardization for a digital signal - it simply did not exist - it was a TV bought at the price of a new mid-range car and was 40 inches. If it is not possible, it is very weak on the part of the producers.
    Or maybe some external decoder with the integration of control from the TV remote control? Something like the Sony Ecosystem, where with one TV remote control I can operate Ampli, TV, VCR, DVD, BD, etc.?

    But the TVs already had digital ones because that's the only sense to install digital tuners in a plasma one that meets at least the minimum HDTV requirements for a resolution of 1280 x 720, and not just an analog head. If you watched after eliminating analog broadcasting, it must have had a DVB-T tuner. The CI is only a decoding card, not a TV reception.
    DVB-T tuners have been installed in TV since the beginning of 2000 as a standard. There has been no analog TV in Poland since 2006.

    As for the control from the remote control of the old TV, I will not say whether such a set with HDMI-CEC for the new tuner will definitely work.

    Well, it's a pity if this cannot be done in an elegant way, only with an external device. In addition, in my opinion, the digital TV standard should be more elaborated in terms of backward compatibility. Sure it would technically be done, but I think that this is another leap in the money of TV producers and set-top boxes and such a kind of collusion on the DVB-T standardization. The analog worked with, say, extra supplies for almost half a century in color, and now the system changes every 10-15 years? As for me, it makes no sense, and it could have been done differently.

    For me and in the opinion of my friends, classic television died 5-10 years ago. For most people, the TV serves as a screen / monitor (game console or
    computer) or those with built-in support use the Internet and streaming (netflix, HBO, CDA, youtube). For me, if not for children and TVP ABC or fairy tales plus 2, the antenna would be unnecessary. Nowadays, hardly anyone has time to wait and set the day for the hour of their favorite series or movie (two things that are played are either antiques or something that cannot be watched). And this is how I turn on the internet and watch what I want and when I want.

    The new standard cannot be backwards compatible with the old one because then there is no point in introducing the new one while keeping the old one. The new one is usually better, takes up less bandwidth, and allows you to use a higher resolution. So either you only introduce new standards or stick with the old and the new, which again causes more problems than benefits.

    Usually it is enough that the latest hardware is backward compatible. ;) Unfortunately, it is not possible to produce forward-compatible equipment to meet the new standards. :P

    Software solutions would be ideal but not achievable on such weak processors in chipsets. Even an older and good computer with a good one, e.g. with an older Intel or AMD processor with a minimum of 4 cores at 2-3 GHz, will not be able to 100% decode HEVC at higher resolutions than FullHD without hardware support in the processor or graphics.

    .




    So to deal with software, you need to connect graphics to the TV? These old procks with graphics, as I remember, coped with playback, and since the codec fired on a very old pc, it should also be on a much newer TV. Probably only the CI card is such a bottleneck that the power from the graphics card would be useless. In laptops there is some output for external graphics cards, if there was something similar on the TV, then future standards would be ok

    Hello,
    I am asking for forgiveness if my question is naive, but I am green in the subject of television, and this is the only thread I found on the Internet that raises the issue of set-top boxes in a meaningful way.

    I have a Sony KDL50WF660 TV.
    On the website Telewizjaaziemna_pl they inform that the TV set supports DVB-T2 / HEVC.
    In turn, on the manufacturer's website (www_sony_pl / electronics / support / articles / 00243412) this model is listed as an exception, which is not compatible with the DVB-T2 tuner and H.265 / HEVC video codecs.
    I checked the TV on the "Check TV" channel and I have a beautiful picture and sound, so until now I was convinced that the change of the standard did not apply to me.
    From Monday 23/06/2022 (I am receiving the signal from Opole), there is no access to the changed multiplexes. There is 0 on the channels where the signal level should be.

    Hence my questions: Why am I not receiving channels in the new standard, since the channel "Checking TV"?
    And in this situation, am I doomed to a set-top box, is there any chance that the problem can be solved by, for example, configuring the TV set?

    I would be grateful for any advice.

    Switching to Germany sometimes helps (not just setting the language). Only in the DVBT tuning menu.
