Waqti dheer ayaa tagay maalmihii la macaamilka cajaladaha fiidyowga si loo duubo barnaamijyada telefishinka ee aad ugu jeceshahay (carruur 80-meeyadii way garanayaan waxaan ka hadlayo). Hadda waxaad iibsan kartaa qalab qaban doona isla hawsha dhowr jeer oo keliya ee kontoroolka fogfog. Hase yeeshe, xitaa jawiga dhijitaalka ah ee maanta, waxaa jira dhibaatooyin la socda ku habboonaantaas.

Arrimaha ugu waaweyn ee laga yaabo in mid ka mid ah laga yaabaa in la leh cajalad duube digital ah ( DVR ) waa in aad ku dheggan tahay wax kasta oo awoodaha la socda qalabka. Taas, oo ay ku jirto kharashyada dheeriga ah ee lagu soo rogay biilka ISP -gaaga billaha ah, waxay dadka ka celin kartaa gebi ahaanba. ^(ISP)Haddaba maxaadan u dhisin adiga oo keliya?

Dhisida DVR kaaga maaha mid adag sida qofku u rumaysan karo. Iyada oo dhawr qaybood oo ka mid ah qalabka shelf-ka-baxsan, waxaad iska dhaafi kartaa bixinta khidmadda adeegga bisha ee guud ahaan la socota isticmaalka sifada noocaan ah.

Taas oo kaliya maaha ee maadaama aad adigu samayn doonto, waxaad yeelan doontaa awood aad wax kaga bedesho tignoolajiyada mar kasta oo aad dareento baahi. Tan waxa ka mid ah balaadhinta saldhiga kaydinta iyada oo loo marayo casriyaynta wadista adag iyo isku dhafka isticmaalaha wax si sahlan loo maro.

DVR asal ahaan waa darawal adag, oo leh awood uu kula xidhiidho TV-gaga, iyo qaar ka mid ah software-ka weheliya ee kaa caawinaya inaad gacanta ku dhigto. Marka, jooji bixinta kharashka bilaha ah marka aad u isticmaali karto kombuyuutar hore oo hore si fiican uga faa'iidaysan kara.

Sida Loo Bedelo Kombayutarkaga DVR^{(How To Turn Your Computer Into a DVR)}

Si aad u samaysato saldhig DVR kaaga cusub , waxa aad doonaysaa in aad boodhka ka jafto kumbiyuutarkii hore ama aad soo iibsato mid la cusboonaysiiyay oo^{(buy a refurbished one)} aad ku heli karto jaban. Haddii aad leedahay wax qorshe ah oo aad mustaqbalka ku ballaadhinayso ama aad ku rakibayso qaybo cusub, kombuyuutarku waa jidka aad ku socon karto. 

Waxaad isticmaali kartaa laptop laakiin way adkaan doontaa in la cusboonaysiiyo maadaama intooda badan ay aad ugu xadidan yihiin waaxda balaadhinta. Mac^{(A Mac)} sidoo kale waa doorasho wanaagsan laakiin kombuyuutarku wuxuu caadi ahaan yeelan doonaa doorashooyin badan oo la heli karo.

Duubista fiidiyoowga qeexida caadiga ah (SD) uma baahna wax badan habka awoodda. Duubista iyo daawashada muuqaalada qeexida sare (HD) ama Blu-ray waa bahal ka duwan gabi ahaanba. Mar kasta oo qeexitaanku sarreeyo, waxaa loo baahan doonaa awood badan. 

Markaad dejinayso DVR -gaaga , waxaad u baahan doontaa inaad fiiro gaar ah u yeelato qaybo gaar ah.

• Processor – Ilaa inta aad haysato Processor ku shaqayn kara nidaamyada hawlgalka ee ugu dambeeyay, uma baahna inuu noqdo wax gaar ah. Codaynta DVR waxaa lagu maamuli doonaa kaarka qabashada TV-ga, isagoo ka qaadaya culeyska garbaha processor-ka.
• Hard Drive - Duubista hal filim, gaar ahaan HD, waxay sida caadiga ah kuugu kici doontaa gigabyte ama in ka badan oo ah meel adag. Noocan oo kale ah ayaa si degdeg ah isu soo kordhin kara si aad u haysato meel ku filan si aad DVR -gaagu u socoto waa lama huraan. Hard Drive-yadu waxay noqdeen kuwo raqiis ah sannadihii la soo dhaafay, markaa iibsashada mid cusub waa inaanay shandadaada dab qabadsiin. Si kastaba ha ahaatee, haddii aad ku xayiran tahay lacag caddaan ah, waxaad had iyo jeer kordhin kartaa hadhow marka dariiqa adag ee bilowga ah uu buuxsamo.
• Graphics/Video Card - Tani waxay noqon doontaa qaybta ugu qaalisan ee habaynta DVR^(DVR) gaaga . Waxaad u baahan doontaa kaadh awood leh oo kugu filan oo farsamayn kara calaamada fiidyaha ee loo soo dirayo TV-gaaga. HD iyo Blu-ray waxay u baahan doonaan kaadh muuqaal ah oo leh xoogaa faras wanaagsan ah. Ha^(Don) ka baqin inaad ku dhufato qaybtan maxaa yeelay tani waxay ku xidhan tahay waxa ay indhahaagu ku eegi doonaan marka ay timaado tayada muuqaalka la daawado.
• Xusuusta^(Memory) - 2GB ee xusuusta gelitaanka random ( RAM ) waxay xaqiijin doontaa waayo-aragnimada fudud ee qeexitaankaaga caadiga ah ee DVR . Si kastaba ha noqotee, cusboonaysiinta 4GB^(Though) + waxay ka dhigi doontaa in welwel kasta oo HD uu si dhakhso ah u libdho. Wax badan ayaa had iyo jeer ka wanaagsan RAM- kuna wuxuu u janjeeraa inuu noqdo mid aan qaali ahayn maalmahan.
• Bixinta Korontada^{(Power Supply)} – Marka ay sii xoog badan yihiin qaybaha aad kor ku dooratay, waxa loo baahan doonaa awood badan si loo socodsiiyo. Ka raadi khadka tooska ah xisaabiyaha korontada ( PSU ) si aad u go'aamiso inta awood ee DVR -gaagu u baahan tahay.

Kaararka Qabashada TV-ga^{(TV Capture Cards)}

Si ka duwan inta badan TV-yada maanta, kaarka qabashada TV-ga wuxuu la yimaadaa tuner u gaar ah si uu u helo calaamadaha telefishinka. Kaararka qabashada xariiqda ugu sarreeya waxay yeelan doonaan soo-saareyaal dusha sare leh kuwaas oo awood u leh inay qabtaan dhammaan cod-bixinta calaamadaha. Tani waxay culays badan ka saari doontaa processor-ka ugu weyn ee kumbiyuutarka si aad mid u iibsato. 

Markaad eegayso waxyaabaha gaarka ah ee kaadhkaaga qabashada fiidyowga, waa muhiim inaad raadiso mid awood u leh inuu aqbalo qulqulka gaadiidka MPEG-2 ee DBV iyo ATSC labadaba . Kaararkan waxaa mararka qaarkood loo yaqaan kaadhadhka hardware-ka dhijitaalka ah waana nooca ugu wanaagsan ee kaadhadhka qabashada fiidyowga marka la eego inta badan TV-ga si dhijitaal ah ayaa loo sii daayaa halkii analooga ahayn.

Inta badan kaadhadhka duubista fiidyowga ayaa ah kuwa isku xidha qaybaha durugsan ( PCI ) ama kaadhadhka PCI -Express waxayna geli karaan boosaska Motherboard-ka ee kombiyuutarkaaga. Waxa kale oo jira aalado qaadis muuqaal ah oo qaadi kara booska USB 2.0 haddii aad doorbidayso jidkaas.

Software-ka DVR^{(DVR Software)}

Marka ay timaado software-ka loo baahan yahay in lagu socodsiiyo DVR , waxaa jira fursado badan oo la heli karo. Qaar ka mid ah xulashooyinkaan xitaa waa bilaash isticmaalka. Kaadhkaaga qabashada fiidyaha ee aad dooratay waxa laga yaabaa inuu xataa la yimaado barnaamijkiisa DVR oo aad dooran karto inaad isticmaasho iyo inkale. Ilaa iyo inta aad jeceshahay software-ka, waxay kaa badbaadin kartaa wakhti iyo lacag adoo raadinaya software dheeraad ah.

Ikhtiyaarada software-ka ee aad haysato waxaa go'aamiya nidaamka qalliinka ee aad dejisay. Nidaamka hawlgalka Linux wuxuu leeyahay ^(Linux)MythTV (doorasho bilaash ah) ama SageTV . SageTV waxa kale oo loo isticmaali karaa Windows OS- ka kaas oo faa'iido leh haddii aad dooratay in aad laba-boob ka dhigto labada nidaam ee hawlgalka^{(dual boot the two operating systems)} . 

Daaqadaha^(Windows) sidoo kale waxay geli karaan GB-PVR (free) iyo BeyondTV . Isticmaalayaasha Mac waxay heli doonaan Elgato's EyeTV ama Miglia's EvolutionTV midka ugu fiican ee lacagtooda. Ka dib waxaa jira NextPVR oo ka shaqeeya dhammaan saddexda.

Tani weli waa doorasho kale oo shakhsi ah sida interface user iyo habaynta ayaa runtii dhammaan ku kala duwan codsiyada. Qaar waxay u baahan doonaan isku xirka internetka si ay macluumaadka barnaamijka ugu soo diraan DVR kaaga halka kuwa kalena ay isticmaali karaan biraawsarkaaga.

How To Turn Your Computer Into a DVR

Long gone are the days of deаling with videotapes in ordеr to record your favоrite television programs (80s kids know what I’m talking about). Yоu сan now buy а device that will do the same task in just a few clicks of a remote control. Yet, even in today’s digital climate, there are complications that come with such convenience.

The main issues one may have with a digital video recorder (DVR) is that you’re stuck with whatever capabilities come included with the device. That, on top of the additional charges tacked on to your monthly ISP bill, can turn people away altogether. So why not just build your own?

Building your own DVR is not as daunting as one may believe. With a few pieces of off-the-shelf equipment, you can forego paying the monthly service fee that generally accompanies the use of such a feature.

Not only that but since you’ll be doing it yourself, you’ll have the capability of modifying the tech whenever you feel the need. This includes expanding the storage base through hard drive upgrades and tweaking the user interface to something more easily navigable.

A DVR is essentially just a hard drive, with the ability to interface with your TV, and some accompanying software that helps you take control. So, quit paying for the monthly feature when you could put an old desktop computer to good use instead.

How To Turn Your Computer Into a DVR

To establish a base for your new DVR, you’re going to want to dust off an old computer or buy a refurbished one you can get on the cheap. If you have any plans to expand in the future or install newer components, a PC is the way to go. 

You could use a laptop but it’d be difficult to update as most are very limited in the expansion department. A Mac is also a decent choice but a PC will normally have far more available options.

Recording standard definition (SD) videos won’t require much in the way of power. Recording and watching high definition (HD) videos or Blu-ray is a different beast entirely. The higher the definition, the more power will be needed. 

When setting up your DVR, you’ll want to pay attention to a few specific parts.

• Processor – So long as you have a processor that can run the latest operating systems, it won’t need to be anything special. The encoding for the DVR will be handled by a TV capture card, taking the heavy lifting off of the processor’s shoulders.
• Hard Drive – Recording a single movie, especially in HD, will normally cost you a gigabyte or more of hard drive space. This sort of thing can add up quickly so having enough space to keep your DVR going is a must. Hard drives have become rather cheap over the years so purchasing a new one shouldn’t set your wallet on fire. However, if you’re stuck for cash, you can always expand later on once the initial hard drive fills up.
• Graphics/Video Card – This will be the more costly portion of your DVR setup. You’ll want a powerful enough card that can process the video signal being sent to your TV. HD and Blu-ray will require a video card with some decent horsepower. Don’t be afraid to splurge on this component as this is tied into what your eyes will be staring at when it comes to the quality of video being watched.
• Memory – 2GB of random access memory (RAM) will ensure a smoother experience for your standard definition DVR. Though, an upgrade to 4GB+ will make it so that any HD worries fade rather quickly. More is always better and RAM tends to be rather inexpensive nowadays.
• Power Supply – The more powerful the components you’ve chosen above, the more power will be required to run them. Look online for a power supply (PSU) calculator to determine how much power your DVR is going to need.

TV Capture Cards

Unlike most TVs today, a TV capture card comes with its own tuner to receive television signals. Top of the line capture cards will have onboard processors that are capable of handling all of the signal encodings. This will take a lot of stress off of the computer’s main processor so look to purchasing one. 

When looking into the specifics of your video capture card, it’s important to look for one capable of accepting an MPEG-2 transport stream in both DBV and ATSC. These cards are sometimes referred to as digital hardware cards and are the better version of video capture cards seeing as most TV is broadcast digitally rather than analog anymore.

Most video capture cards are either peripheral component interconnect (PCI) or PCI-Express cards and can fit into slots on the motherboard of your computer. There are also video capture devices that can take up a USB 2.0 slot if you’d prefer that route.

DVR Software

When it comes to the software needed to run a DVR, there are plenty of options available. Some of these options are even free for use. Your chosen video capture card might even come with its own DVR software that you can choose to use or not. So long as you like the software, it can save you time and money looking for additional software.

The software options you have are determined by the operating system you’ve settled on. The Linux operating system has MythTV (free option) or SageTV. SageTV can also be used for the Windows OS which is useful if you’ve chosen to dual boot the two operating systems. 

Windows also has access to GB-PVR (free) and BeyondTV. Mac users will find either Elgato’s EyeTV or Miglia’s EvolutionTV the best bang for their buck. Then there is NextPVR which works on all three.

This is yet another personal choice as user interface and customization are really all that differ between the applications. Some will require an internet connection in order to send programming information to your DVR whereas others may use a web browser.

Enjoying The Fruits Of Your Labor

After connecting all internal components and installing the software, connect the newly assembled DVR to your TV. 

1. First, attach your cable connection or satellite cable to the video capture card’s input.
2. Next, connect the DVR computer’s video card to your TV. For HD viewing, an HDMI connection is a must.
3. Connect the audio output of your computer to the inputs on your TV or home theater system.
4. Finish the process by connecting the computer to the Internet and powering everything on. Allow the program list load and you’ll be ready to watch and record TV shows with your non-contractual self-built DVR.
