DVB-T: RTVS disconnects programs in MPEG-2 - SatelitnáTV.sk

In addition to the launch of the new Šport sports station, RTVS is also preparing changes for the distribution of its DVB-T programs for this December.On 13 December, the public service broadcaster will stop broadcasting its programs in the older MPEG-2 compression format in the public multiplex (MUX 3)."After this date, the SD unit will be offered in the public multiplex and the Dvojka SD and Trojka SD program services will only be distributed in the more efficient MPEG-4 compression format," RTVS announced today.In addition, a new Sports HD (MPEG-4) channel will be added.The changes will also be in the first DVB-T2 multiplex (MUX 1), where a new Sport HD channel in the newer HEVC format will appear at the position of the Trojka HD station.Viewers who have an even older device that supports the MPEG-2 format will have to purchase new devices.Ideally, they would already support the newer HEVC compression format.How do I verify that your device supports MPEG-4?If you can currently watch HD Drive, you will still be able to watch RTVS programs.However, if you only have audio in the HD Drive position, your device does not support MPEG-4."In an effort to improve our television broadcasting, we ask viewers of terrestrial broadcasting who use the above-mentioned older types of equipment to purchase the recommended type of television set, resp.set top box, thanks to which they will be able to watch RTVS broadcasts in higher quality, without fees and in the full program offer, "said Roman Skřivánek, director of the RTVS technology section.RTVS is switching to the MPEG-4 compression format after ten years of terrestrial distribution.The termination of SD MPEG-2 broadcasting is necessary for a more efficient use of the capacity of the public multiplex and, in particular, allows RTVS to include a new program service.Finally, RTVS is converting to the MPEG-4 compression format.But that took them.Why is it not possible in Slovakia as in the public mux of Czech Television.I really don't understand.In our country, they all were forced to simply switch to HEVC 265, and it was not wasted and unnecessary to broadcast on other muxes and in duplicate.After all, this is ordinary chaos.CT has 6 Stations + 2 for Moravia and Silesia + radio in one mux and it's good quality, so why couldn't Stv broadcast 4 stations in HD plus the radio on one mux doesn't bother me .. It's all about people and probably there bad people are sitting on those chairs.This would not happen with us !!I understand that too, so the trio will only be in SD.In my opinion, this means that in Mux 3 (public) from the 13th of December there will continue to be the HD Unit, the SD Unit will turn off completely, the SD Unit can be switched to HD / MPEG4 or disconnected, the SD Unit will be switched to HD / MPEG4 and they will also add sports. HD / MPEG4.In Mux 1, the HD Two (MPEG4) may be disconnected and the HD Three (MPEG4) will switch to Sport HD (HEVC).So I understand that from the text.It would be nice if the editors found out the details if they don't know them yetSo those RTVS technicians are really crappy and managers are really tunnelers!It really wants to spread the HD Unit in MUX 3, which is already there in MPEG-4 / H264, and the new Two with the Three further in SD, but only with the difference that these two stations will no longer be in MPEG-2 but new in MPEG-2. 4 (when the article says "Two SD and Three SD will only be distributed in the more efficient compression format MPEG-4") and will Sports HD in MPEG-4 / H264 be added there?So HD Two will only remain in MUX 1 HD (which is also in the DVB-T2 standard) and HD Three will become a duplicate Sport HD with the difference that there will be no MPEG-4 / H264 but in HEVC / H265?Super experts from RTVS for the fact that you will continue to pay Towercom for two MUXy and in the final you will have only Unity with Two in HD according to this article, with the fact that you will continue to broadcast Sports HD twice (1x in Mux 3 and 1x in MUX 1) and Trojka will be just SD ?!RTVS should leave MUX 1 completely, staying only at MUX 3 where Unit HD, Two HD, Three HD and Sport HD would be in MPEG-4 / H264.SRo - Slovak Radio has nothing to do in DVB-T and there is an FM band or possibly DAB.RTVS is indeed probably the richest public service TV in Europe when it can afford to pay for two MUXes just to broadcast four stations.All those who invented and approved this public tunneling of money from paying dealers should sit in the crime scene, return this tunnel on their own, or confiscate their property.As far as I know, RTVS pays nothing for MUX1.Question of the day.How to use efficient 19.91 Mbit / s for four TVs and radios?For Zero: If they don't want to flip MUX 3 to T2 yet, at least let them change the convolution interval from 1/4 and 2/3 to 1/8 and 3/4.As a result, the flow would increase from 19 Mbps to 24 Mbps.There are no limits to foolishness, Slovakia flourishes with foolishness.Why couldn't all 4 RTVS programs be in HD in muxe3.The Hungarians also have muxe programs M1 HD, Duna HD, Duna World HD, M4 Sport HD and 4 more radios.The capacity of the Hungarian mux is 22.39 Mbit / s, the capacity of our mux is even 24.88 Mbit / s, so I don't see any problem with that.I guess all RTVS HD programs will be in public mux, because it has no logic or what RTVS Sport HD 2X will have, only if the public muxe has a resolution of 720p and 1 muxe 1080p hevc, because otherwise I don't understand.Well, when I read the discussion of these articles, I see chaos in it, when I read it.Maybe it's like this: MPEG2 - SD, HD - turn off RTVS 1, 2, 3RTVS SPORT HD - H265 / HEVCThe MUX 3 public multiplex RTVS was long overdrawn in the H265 / HEVC codec.Well, in this of our Slovakia, this cesspool has been stealing for 28 years since the division of the republics of the Czech Republic and the Slovak Republic.No one here is doing business as honestly and honestly as such a state.We have capitalism - "hamba".Well, I see that you yourself "read" wrong!The article makes it clear: On 13 December, the public service broadcaster in the public multiplex (MUX 3) will stop broadcasting its programs in the older MPEG-2 compression format."After this date, the SD unit will be offered in the public multiplex and the Dvojka SD and Trojka SD program services will be distributed only in the more efficient MPEG-4 compression format,"So I see that you don't understand when you write "MPEG 4 HD - turn on RTVS 1, 2, 3"Someone find in that article where it is clearly written that Two and Three will stay in HD.I don't see this anywhere, but only that SD Two and SD Three will continue to be in MPEG-4 and not in MPEG-4 HD.MPEG-4 and MPEG-4 HD are completely two different things !!!It goes on to say there: The changes will also be in the first DVB-T2 multiplex (MUX 1), where a new Sport HD channel in the newer HEVC format will appear at the position of the Trojka HD station.So again, there is nothing clear about the fact that Trojka will stay in HD.If this is an exact copy of the report from RTVS, then there is probably a good amount in RTVS if it cannot state it clearly.Another possibility is that even the RTVS does not know how it will be at all.@BMX: You confused it a bit - What a citizen, such a government!there it begins… and do not blame Saa, he is innocent tomWell, I would also like to see it so clean in muxes….also with prices 🙂(2 Euro) Mux1: MarkizaHD, DajtoHD, DomaHD, TA3HD, PrimaPlus720, PrimaCool720, CT1720, CT2720, (2 Euro) Mux2: JojHD, PlusHD, Wau720, JojSportHD, Jojko720, JoJ CinemaHD (Free) Mux3: JednotkaHD7 Dvojka , SportkaHD, Lux720 (3 Euro) Mux4: all the othersI don't understand the prices.But it's not as easy as you think.Some TVs pay for themselves and decide what Muxe and codec they will be.In addition, MUX3 is by law reserved for RTVS only.Nothing else can be there.Exactly as you write (only for Mux 3 SK there is not 24.88 Mbit / s as you write but really only 19.91 Mbit / s), in Mux 3 there can be 4 RTVS programs in HD H264 / AVC without any problems.When modulating: QAM 64, code ratio: 2/3, security interval 1/4, transmission mode: 8K (DVB-T) the net transmission speed is 19.91 Mbit / s.Even if it reads 1.4 Mbit / s from the Mux as a reserve, the data flow of 18.5 Mbit / s still remains, which is enough for the 4 stations.In the SK land, Unit HD + Two HD now has three audio tracks (1. SK 192 kbit / s, 2. original 192 kbit / s and 3. AD-audio commentary 64 kbit / s), Trojka HD has only two audios ( 1, SK 192 kbit / s and 2nd AD-audio commentary 64 kbit / s) and the RTVS Sport point costs the two audios (1, SK 192 kbit / s and 2nd AD-audio commentary 64 kbit / s) where there is no need for peace of original sound such as in foreign films.So the sounds occupy 6x audio 192 kbit / + 4x 64 kbit / s which is a total of 1,408 Mbit / s.When the reserve of 1.4 Mbit / s is subtracted from the net transmission speed of 19.91 Mbit / s of Mux 3 for some unexpected peaks of the need for higher data flow, it still remains 18.5 Mbit / s and when it is then subtracted another 1,408 Mbit / s for sounds so it stays on video + on EPG and TXT for a total of 4 stations 17,092 Mbit / s, which is one station for video with EPG and TXT 4,273 Mbit / s.E.g.for an idea on Antik SAT 16.0 ° E u Jednotky HD average data rate 3,711 Mbit / s and Dvojky HD (where sport is taught) 4,199 Mbit / s.Towercom from 23.5 ° E - Unit HD average data rate 4.998 Mbit / s and Two HD 4.964 Mbit / s.So I don't know, in CrazyScan2 the muxe3 really says 24.88Mbit / s.But in the AltDVB program at muxe2 the baud rate fluctuates in the range of 2380-2488 kB / s and when I convert it to Mbit / s, the max.is 2488/1024 * 8 = 19.44Mbit / s resp.2488/1000 * 8 = 19.90MBit / s.So probably the AltDVB shows it well.It has a Hungarian mux 2684-2790 kB / s, ie max.is 22.32 Mbit / s.This value is almost identical to CrazyScan2 (22.39Mbit / s).But it's interesting because the Hungarian mux has essentially the same baud rate in both applications, but the Slovak no longer has it.Here is the screen from CrazyScan2 https://files.fm/f/e8xrkq8c9* fix: "Well in AltDVB at muxe2" should be muxe3Mr. Zdenek I agree with you that RTVS is to broadcast all TV stations on one frequency, as is the case with Czech public television.which is one of the best public service broadcasters in Central Europe, but I do not agree with your view that DVBT- do not broadcast radio, they broadcast on DVBT- throughout EuropeA bit off topic 25k AVIS Veľké Hradisko has been added to TV Považie.So it is already known how it will be after the 13th, resp.after December 20 ???the transition to MPEG4 in mux 3 is done in order to spread all RTVS television circuits in better technical quality.Otherwise, the change would not matter.In mux 3 I will definitely siren all (four) stations in HD.I don't understand why the RTVS press department published it so confusingly.Just write from the end of SD / Mpeg2 and it will flip to HD / Mpeg4.Igor 28.11.2021 at 13:39 If in your opinion all four will be broadcast in MUX 3 (RTVS stations in HD so what would be the point of distributing RTVS stations in duplicate in MUX 1 which has worse coverage and even more so in DVB-T2 compared to DVB-T2! I would like to see how many viewers have a TV older than 12. Those who still own a glass CRT TV or the very first pancakes more than 15 years old only with DVB-T MPEG-2, so it's really so in the collection yard because there the picture must be totally in a mess and it is just like destroying the eyes like in the fog behind the haze !!! If I have a concession fee to pay, do I have a one-time 20 Euro for a new set-top box or do you think not?I'm not saying anything either.Plustelka and RTVS know that there are few devices with HEVC support among viewers, so they are still reluctant to go to T2 / HEVC.They know that such a change would cause considerable resentment.In contrast, only MPEG-2 devices are about 5%.Most viewers should have no trouble switching to mpeg4.There is no more room for another RTVS channel in mux1.Therefore, it is less painful to switch mux3 to dvb-t / mpeg4 and broadcast in hd.If RTVS broadcasts sport in mux1 in the HEVC codec, RTVS can claim that it is a test and a contribution to the future transition to HEVC with the possibility of extension to another program. does not run an information campaign to ensure that viewers affected by this change purchase equipment only with T2 / HEVC support.Hello.You're obviously right about everyone.The result will be MUX3: Drive HD Mpeg4, Two SD Mpeg4, Three SD Mpeg4, Sport HD Mpeg4.MUX1: Two HD Mpeg4, Sport HD HEVC.By law, RTVS must have everything it broadcasts in MUX3.RTVS does not pay for the capacity in MUX1 unless it goes to T2.For me, HEVC is a path not only to higher quality but also higher resolution.Next year, they could retune MUX3 to T2, combine it with switching everything to HD, and even turn on Sport in UHD HEVC.But according to that report from RTVS, the SD Two with the SD Three in MPEG-2 will switch to MPEG-4 but will remain in SD and not HD.So in the Mux, the MPEG-2 SD Unit will be completely eliminated and replaced by the new RTVS Sport HD in MPEG-4.Mux 3 DVB-T will be the new HD MPEG-4 Unit, the two SD MPEG-4 Units, the SD MPEG-4 Units and the RTVS Sport HD MPEG-4 Unit.In Mux 1 DVB-T2, the HD Two MPEG-4 will remain unchanged, the HD Three will be switched off and replaced by RTVS Sport HD HEVC.So after this change, Trojka will no longer be in HD in the terrestrial (by the way, it is not even from SAT 23.5 ° E to RTVS cards) but only in SD, and thus a change for the worse and especially that RTVS Sport will spread twice in HD quality.Only a total "mgr" can really come up with this and someone with intelligence and common sense !!!for God's sake, what's the money over dead TV here?who is watching STV?masochists?these are unobtrusive programs that only serve to get there mullerka, brychtova, malachovska, marcin, nikodym… etc., on those they forgot I'm sorry, it's not a hit 🙂@obcan Kane> what are those unseen programs on rtvs fesak?For the sake of interest, I assume that your standard of interest is, for example, the Marquis on Tuesday (what should I watch?): 05:00 Television newspaper 06:00 Teleráno 08:25 Swapping wives 09:45 Fathers 10:45 Family cases 11:45 Cobra 11 12 : 45 Cobra 11 13:50 Farm 14:55 Police cases 15:55 Family cases 17:00 First television newspaper 17:25 Reflex 17:55 Dads 19:00 Television newspaper 20:05 Weather 20:20 Sports newspaper 20:30 Nurses 20:55 Farm 22:00 Wife swap 23:20 Police cases 00:30 Cobra 11 01:30 Cobra 11 02:35 Police cases 03:20 Farm 04:20 Family casesOIOI, you have to realize that for some people, commercial programs (see your list from Marquis) are the best choice, given the IQ of the viewer in question.For me, the best free program is Dvojka.Fte: also for me without debate.BTW today at 22:15 rtvs2 Bobo.Successful Croatian cinema club.pooh, I only use DVB-T as a backup in adolescents' rooms, the main signal goes via satellite.Since LG and PHILIPS LED TVs are still functional in their rooms, which HEVC can't handle, I would have to buy STB boxes.I don't think it is necessary to switch to HEVC next year with the content quality of MUX 3.MPEG-4 will definitely suffice for those RTVS channels, and people can continue to watch those programs on their functional TVs.Of course, it will not be possible to switch to HEVC in mux3 in a year.There is an agreement between Towerco and RTVS that they will act in a coordinated manner.After the changes in mux3, there is no pressure to change the codec, because it would not bring anything.There will still be 4 TV programs.If the 5th program started broadcasting, HEVC would be important.The current management of RTVS will live to see the status quo.But four stations from RTVS in HD will easily fit into the public MUX 3DVB-T (not DVB-T2) in good picture quality.Therefore, I would expand Slovak Radio as much as possible in MUX 1, but this should be preferred in MUX 2 because TVs with the DVB-T2 standard do not have many viewers.I don't see the awning jojka as a year long and those all kinds of hbo cinemax filboxes are all American gichs.Kamil you write that MPEG-4 is enough for you and how you watch Czech stations that have been broadcasting on DVB-T for a long time - HEVC MPEG -4 in the Czech Republic is no longer about anything.tono, I'm saying the main source is the satellite in the living room.DVBT is only a backup in the rooms of the descendants.I don't catch Czech DVB-T, I'm from Prešov, there is no cross-border overlap from the Czech Republic.Kamil I'm sorry I'm from western Slovakia where there is a quality DVB-T signal from Austria and the Czech Republic.Comments are no longer allowed.- The TV program will soon be expanded with the sports channel Eurosport 4K, lifestyle E!and children's Cartoon Network and Disney Channel.
