What is necessary for DLNA?

My friend suggested me to set up DLNA. LOL, I even don’t know what DLNA is. He explains me a lot of it, but I’m still puzzled. If I’m going to set, what do I need? If the DLNA has been set up, what will be different?

The Digital Living Network Alliance (DLNA) is a non-profit collaborative trade organization established by Sony in June 2003, and has more than 250 member companies in the mobile, consumer electronics, PC, and service provider industries. Alliance members have stated the common goal of using standards-based technology to make it easier for consumers to use, share and enjoy their digital photos, music and videos. As of January 2011, more than 9,000 different devices have obtained "DLNA Certified" status, indicated by a logo on their packaging and confirming their interoperability with other devices. It is estimated that more than 440 million DLNA-certified devices, from digital cameras to games consoles and TVs, have been installed in users' homes.

Member companies

As of June 2011, there are 26 promoter members and 199 contributor members. The promoter members are: ACCESS, AT&T Labs, Awox, Broadcom, Cisco Systems, Comcast, DIRECTV, Dolby Laboratories, Ericsson, Hewlett-Packard, Huawei, Intel, LG Electronics, Microsoft, Motorola, Nokia, Panasonic, Promise Technology, Qualcomm, Samsung Electronics, Sharp Corporation, Sony Electronics, Technicolor, and Verizon.

Products supporting DLNA

DLNA-certified devices

There are over 9,000 products on the market that are DLNA Certified. This includes TVs, DVD and Blu-ray players, games consoles, digital media players, photo frames, cameras, NAS storage, PCs, mobile handsets, and more. Predictions have been made as to how many DLNA Certified products are shipping: “According to a study from ABI Research, nearly 200 million such products shipped in 2008; that number will rise to more than 300 million in 2012, and the growth curve accelerates even faster in the years that follow.” Consumers can see if their product is certified by looking for a DLNA logo on the device or by verifying certification through the DLNA Product Search: http://www.dlna.org/products/

DLNA technology components

As the past president of DLNA pointed out to the Register in March 2009:

"The vendors of software are allowed to claim that their software is a DLNA Technology Component if the software has gone through certification testing on a device and the device has been granted DLNA Certification. DLNA Technology Components are not marketed to the consumer but only to industry."

DLNA Interoperability Guidelines allow manufacturers to participate in the growing marketplace of networked devices and are separated into the below sections of key technology components.

• Network and Connectivity
• Device and Service Discovery and Control
• Media Format and Transport Model
• Media Management, Distribution and Control
• Digital Rights Management and Content Protection
• Manageability

DLNA-certified software

In early 2011, DLNA began a Software Certification program that makes it even easier for consumers to enjoy and share their digital videos, photos and music across a broader range of popular products. DLNA is now certifying software that is sold directly to consumers through retailers, websites and mobile application stores. With DLNA Certified software, consumers can upgrade products from within their home networks that may not be DLNA Certified and bring them into their personal DLNA ecosystems. This helps in bringing content such as videos, photos and music stored on DLNA Certified devices to a larger selection of consumer electronics, mobile and PC products.

The first application to be certified under the new Software Certification program was Skifta for Android, a product of Qualcomm Services Labs Inc. Skifta is an application-based media shifting service that allows consumers to access and play their digital media from virtually any source, whether it's accessed on the phone, from the cloud, or remotely from home

How it works

Find and play movies

Your movie collection is stored on your network attached storage (NAS), a certified digital media server (DMS). Instead of watching the movie on the little PC monitor in your office, you want to enjoy it on the large flat-panel TV in your living room. Because your DLNA Certified TV is certified as a digital media player (DMP), you can use the DMP capabilities of your TV to find the movies on your NAS, and then play them on the TV.

Send and display photos

You have photos stored on your digital camera, a certified digital media controller (DMC). You want to look at them on your TV. With a DLNA Certified camera, you can send the photos to your DLNA Certified TV, which, if certified as a digital media renderer (DMR), can use those capabilities to display the photos.

Find, send and play music

You’ve loaded all your favorite music onto your PC, a certified digital media server (DMS). Using your DLNA Certified personal digital assistant (PDA), which may be certified as a mobile digital media controller (M-DMC), you can find songs you want on your PC and send them to play on your DLNA Certified wireless speakers. In this case, the speakers deliver the capabilities of a certified Digital Media Renderer (DMR).

Upload photos

There are photos on your personal digital assistant (PDA), a certified mobile digital media uploader (M-DMU), you want to send and save to your newtork attached storage (NAS). Using a DLNA Certified PDA, you upload the photos to your DLNA Certified network attached storage (NAS), which operates as a certified Digital Media Server (DMS).

Download music

You want to transfer music from your PC, a certified Digital Media Server (DMS) in this scenario, to your MP3 player, a certified mobile digital media downloader (M-DMD). With DLNA Certified devices, you download the music from your PC using the MP3 player.

Send and print photos

You have a photo on your WiFi enabled camera phone you want to print. Assuming the phone is a certified mobile digital media controller (M-DMC), you can send the photo to your DLNA Certified printer, a certified digital media printer (DMPr), to print.

DMS and DMP are the most important elements for DLNA. Of course, some DMPs would function as DMC.

For example, you could have your WD TV Live Plus connected to the share network for your Windows 7 PC. Windows 7 is DLNA compliant. Then stream videos from PC to WD TV Live Plus via network, instead of copying files to external hard drive of WD TV Live Plus.

It saves you from getting messy cables when you get several DLNA devices.

The guy of #2 has introduced you what DLNA is particularly.Now,I just want to give you the answer in one sentence: DLNA connected all your DLNA-certified media devices working together.
