The devices can include a computer, TV, DVR, set-top box, printer, and cell phone.For example, a computer running Windows 7 is already DLNA-enabled and will allow a DLNA-enabled Blu-ray player (with a built-in network connection) to "pull" digital photos and videos from the computer, with no additional software needed.Services may be added or removed with future firmware updates.This feature allows your player to connect to the Internet or to a home network without the use of a wired Ethernet connection.HDMI supports a range of standard- and high-definition video formats, although it can vary for each product.HDMI supports up to eight channels of uncompressed, 24-bit/192k Hz audio.Some players have built-in Wi Fi capability, while others come with a Wi Fi dongle (external adapter) that you plug into the player's USB port.In both cases, we denote Wi Fi as a standard feature.
Lets you play discs formatted in Super Audio CD (SACD), one of two competing audiophile music formats.
This is convenient when your Internet connection isn't near your entertainment setup, which would otherwise require you to run a long cable from room to room.
A growing number of Blu-ray players can use Wi Fi to connect to other DLNA-compliant devices in the home, enabling you to access digital music, videos, and photos stored on a computer or networked storage device and play them on the TV.
Digital-audio outputs are important only if your home-theater system lacks HDMI connections.
As an alternative, you can pipe the digital audio signals--both stereo and multichannel--from the Blu-ray or DVD player, or television set-top box into a digital receiver.
