Codka fiidiyowga ee^{(video codec)} ugu caansan hadda waa heerka H.264 tan iyo ku dhawaad ​​dhammaan aaladaha warbaahinta ayaa taageeraya. Xataa goobaha fiidyowga ah ee shabakada ma caawin karaan, laakiin waxay ku dari karaan taageerada codeckan, iyo sababo wanaagsan aawadood. YouTube , inkastoo ay leedahay u gaar ah, waxaa loo arkaa H.264 , oo tani ma beddeli doono sanadaha soo socda.

Hadda, kama fileyno inuu noqdo eyga ugu sarreeya weligiis iyadoo tartamo badan ay goobta yimaadaan iyagoo rajeynaya inay beddelaan. Waxa ugu caansan waxay u badan tahay inay noqoto nooca la cusboonaysiiyay, H.265 , oo sidoo kale loo yaqaan HEVC ( Footiyaha Fiidiyowga Waxtarka Sare^{(High-Efficiency Video Coding)} ).

Waxa kale oo jira H.266 codec, laakiin aad ayey uga duwan tahay marka la barbar dhigo kuwa kale ee aan hadda soo sheegnay. Ha ka werwerin^(Worry) , si kastaba ha ahaatee, sababtoo ah waxaan u sharaxeynaa mid walba fahamkaaga qoto dheer.

1] Waa maxay H.264 codec

Koodhkani waxa uu jiray ilaa 2009, iyo in muddo ah, waxa uu ahaa heerka. Codka waxaa sidoo kale loo yaqaan AVC , MPEG-4 Part 10 , iyo VC-1 .

Waa halbeeg isku xidhid fiidiyoow ah oo loogu talagalay in lagu soo celiyo muuqaal tayo sare leh oo ka yar RAW iyo heerarkii hore. Waxaan fahamsanahay saamiga cadaadisku waa laba jeer in MPEG-2 , taas oo ah arrin la yaab leh. Waxay ballan qaadaysaa inay bixiso waxyaabo tayo sare leh oo aan lahayn wax tayo leh marka la barbardhigo heerarka kale.

Asal ahaan, haddii cabbirka faylkaagu yahay 88GB, riixitaanka H.264 wuxuu hoos u dhigi karaa in ka yar 800MB. Intaa waxaa dheer, marka la barbar dhigo tignoolajiyada kale ee cadaadiska, heerka hooseeya ayaa door muhiim ah ka ciyaara. Dhammaadka, isticmaalayaashu waxay kaydin doonaan waqti marka ay tahay inay soo dejiyaan ama daadiyaan nuxurka fiidiyowga wakhti kasta.

2] Waa maxay H.265/HEVC codec

Sida laga yaabo inaad ka garan karto magaca, H.265/HEVC waa nooca la cusboonaysiiyay ee hore, waxaana loogu talagalay in lagu beddelo wakhti mustaqbalka ah. Heerka cusub ayaa dib loo sii daayay 2013, laakiin hadda kaliya ayaa helay taageero weyn sababtoo ah kor u kaca 4K.

Tani waxay shaki la'aan sii socon doontaa sanadaha soo socda iyadoo telefishinada 4K iyo kormeerayaashu ay noqdaan kuwo la awoodi karo. Si kastaba ha ahaatee, su'aasha ugu weyn ee hadda, waa, maxaa H.265 ka dhigaya mustaqbalka?

Waa hagaag, haddii aad daawato nuxurka 4K ee YouTube , waa inaad ogaataa in aysan shumac ku haynin fiidiyow la mid ah saxanka Bu-Ray^(Bu-Ray) . Taasi waxay sabab u tahay cadaadiska H.264 inta badan, taasina waa wax codec-ka cusub uu rabo inuu xalliyo.

Wixii aan u nimid inaan fahanno, HEVC waxay isticmaashaa habab isku-buufin oo hufan, sidaa darteed, waxa ku jira dhamaadka waxa ay soo bandhigi doonaan tafaasiil dheeraad ah iyo waxyaabo yaryar. Dhammaanteen waxaan rabnaa tan, taas oo ah sababta aanan u sugi karin soosaarayaal qalab badan si ay u taageeraan heerka mustaqbalka.

Hadda, waxaa jira hal dhibaato weyn oo H.265/HEVC hadda. Waad aragtaa, way gaabis tahay haddii Dardargelinta Hardware^{(Hardware Acceleration)} aanu ku jirin ciyaarta. Haddii aad rabto inaad ku furto HEVC^(HEVC) , markaa kombuyuutar awood leh ayaa loo baahan yahay. Jiilka 6-aad ee Intel^{(Intel 6th)} ama ka cusub, iyo AMD^{(AMD 6th)} jiilka 6-aad ama ka cusub, waa CPU-yada^(CPUs) ay tahay inaad tixgeliso marka aad kombuyuutar ka iibsanayso HEVC .

3] Waa maxay H.266 codec

Dunidu wali si buuxda uma aqbalin H.265 oo ah heerka cusub ee codecs-yada fiidiyooga ah, laakiin horeba H.266 ayaa lagu tilmaamay Fraunhofer HHI , shirkadda ka dambeysa dhammaan saddexda codecs.

Waqtigan xaadirka ah, waxaan fahamsanahay in codec-kan cusub, oo sidoo kale loo yaqaan ' Versatile Video Coding ' ( VVC ), uusan hagaajin doonin tayada muuqaalka hore, laakiin waxaa la filayaa inuu yareeyo cabbirka. Markaa macno ahaan, waxay la mid tahay H.265 , laakiin leh raad yar.

Marka codec-ka H.266 la qaato mustaqbalka, dadka ka yimid adduunka oo dhan waxay yeelan karaan dhibaatooyin yar oo ku saabsan qulqulka 4K ee goobaha ay jecel yihiin. Ma aha in la xuso, waxay kaa caawin kartaa in ay keento xilligii 8K sidoo kale.

Waxaan rajeynayaa in tani ay sharraxayso mawduuca.

H.264 vs H.265 vs H.266: We explain what they are all about

The most popular video codec right now is the H.264 standard since almost all media devices support it. Even video platforms on the web can’t help but add support for this codec, and for good reasons. YouTube, despite having its own, is beholden to H.264, and this won’t change for years to come.

Now, we do not expect it to be the top dog forever as more competitors come on the scene in hopes to replace it. The most notable would likely be the upgraded version, H.265, also known as HEVC (High-Efficiency Video Coding).

There is also the H.266 codec, but it differs a great deal when compared to the others we’ve just mentioned. Worry not, however, because we are going to explain each for your deeper understanding.

1] What is H.264 codec

This codec has been around since 2009, and for quite some time, it has been the standard. The codec is also known as AVC, MPEG-4 Part 10, and VC-1.

It’s a video compression standard that is designed to playback high-quality video at a small size than RAW and previous standards. We understand the compression ratio is twice that of MPEG-2, which is quite astonishing. It promises to provide high-quality content with no quality loss when compared to other standards.

Basically, if your file size is 88GB, H.264 compression can bring it down to a little over 800MB. Additionally, when compared to other compression technologies, low-bit rate plays an important role. In the end, users will save time when having to download or stream video content at any time.

2] What is H.265/HEVC codec

As you might be able to tell from the name, H.265/HEVC is the upgraded version of the previous, and it is designed to replace it at some time in the future. The new standard was released back in 2013, but only now has been getting huge support due to the rise of 4K.

This will no doubt continue in the years to come as 4K televisions and monitors become more affordable. However, the big question right now, is, what makes H.265 the future?

Well, if you watch 4K content on YouTube, you should realize that it doesn’t hold a candle to the same video on a Bu-Ray disc. That is due to H.264 compression for the most part, and that is something the newer codec wants to solve.

From what we’ve come to understand, HEVC uses more efficient compression methods, therefore, the end content will showcase more detail and fewer artifacts. We all want this, which is why we cannot wait for more hardware manufacturers to support the future standard.

Now, there is one big problem with H.265/HEVC right now. You see, it is quite slow if Hardware Acceleration is not in play. If you want to decode in HEVC, then a powerful computer is required. Intel 6th generation or newer, and AMD 6th generation or newer, are the CPUs you should consider when purchasing a computer for HEVC.

3] What is H.266 codec

The world has yet to fully accept H.265 as the new standard where video codecs are concerned, but already H.266 is being touted Fraunhofer HHI, the company behind all three codecs.

At the moment, we understand that this new codec, also known as Versatile Video Coding (VVC), won’t improve video quality over its predecessor, but is expected to reduce the size. So in a sense, it is the same as H.265, but with a smaller footprint.

When the H.266 codec is adopted in the future, people from around the world may have little problems with streaming 4K content on their favorite platforms. Not to mention, it could help usher in the era of 8K as well.

I hope this explains the subject.
