1. A new Blu-ray Disc player that is designed from the ground-up to comply fully with the recently adopted 3D for Blu-ray Disc standard. This means that the Blu-ray Disc player must be able to deliver two simultaneous 1080p signals (one 1080p signal for each eye). In order to do this, the Blu-ray Disc play must employ a new version of HDMI 1.4 that is able to transfer this signal. Of course, on the receiving end, it is required that the TV must be able to receive and process this signal, which will also require that the TV also be HDMI ver1.4 equipped.
2. Based on information that may be subject to change as more details come to light, the second way to implement 3D for Blu-ray may be a "short-cut" method that would allow for a downloadable firmware upgrade for some, or all, currently Profile 2.0 (BD-Live) compatible players that would make them 3D-enabled. This upgrade, if possible, would probably be at the discretion of the player manufacturer. The Sony PS3 is the only confirmed upgrade to 3D for an existing Blu-ray Disc Player product announced so far.
If such an upgrade is actually implemented on a wider basis, it would enable chosen players to access 3D Blu-ray content and send that signal to 3D-enabled TV in the form of two 1080i signals (one 1080i signal for each eye). This method complies with the signal processing capabilities of current Blu-ray disc players. The 3D-enabled TV would then perform any additional processing to display the images on the screen properly so that they can be seen properly by the viewer wearing 3D glasses.
This concept, if actually implemented, would undoubtedly save the expense of having buying a new Blu-ray Disc player and can use the currently used HDMI output from the player, the result is you will still need a 3D-enabled TV and once the two 1080i signals are processed, displayed, and received by your eyes, you will actually viewing a 540p 3D image. In other words, the resulting resolution will not be in high definition, but is a resolution that is one-half the resolution of a full 1080p image and lies just above standard DVD quality in terms of image detail.
The last thing to point out with regards to 3D Blu-ray Discs, is that if you have a 3D Blu-ray Disc movie, you will be able to play it on any 3D-enabled Blu-ray Disc player regardless of brand or model. So, if you and your friend both have 3D-enabled Blu-ray Disc players, you can take your 3D Blu-ray Disc movie and play it on his/her 3D-enabled Blu-ray Disc player. Your friend just needs to have an extra pair of 3D glasses you can with his/her TV.
