What does this imply about the FCC's proposal to > redefine "broadband" as a symmetrical 10 Mbps? Actually, vision is higher bandwidth than that - most VR people estimate that approaching human vision requires a gigapixel/second (at 24 bits or more per pixel) - and even that needs to play lots of eye-tracking games to concentrate the rendering on where the eye is focused. Consider how fast even high-end NVidia cards can pump out pixels and you can *still* see it's CGI. Well-shot 4K video of real objects displayed on a good monitor is *just* reaching the "it actually looks real" level - and that's a hell of a lot more than 4Mbps. And remember that bits are consumed by more than just one human per dwelling - you can have multiple people watching different things, and silicon-based consumers burning lots of bandwidth on behalf of their carbon-based masters. There's about a half-zillion ways a gaming console can burn bandwidth, for example. Heck, the Raspberry Pi under my TV can soak up more than 4Mbits/sec just doing a software update. /me makes popcorn and waits for 4K displays to drop under US$1K and watch the network providers completely lose their shit.... --==_Exmh_1405631724_2078P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Exmh version 2.5 07/13/2001 iQIVAwUBU8g87AdmEQWDXROgAQIzXRAAkmPsFGjfLkKjx5+wYEz3HABbqKrMMW5Q 0ofXl1mi33xfBUFHwA0a+07foOYGKgmxYGzyWsfblab5FeeA2eD2zKa0mz/eh/SD FEIPdtOp+RPCWr8qIg61mQq6z3X1WuuzSXgLroj/rUcvceCT1zYhVYHCTZ6DDRVy gj3r527qu6kONtuZTXgqmc16NwC8XCpD+BwxtgZ5pjGqsCSQWqvuGYTCoePqPUnm dYOU52voHbUCxs9zfQ2FZeGYWiSbzHkZkBnonkMFPYmII1AO/CC6dLZA6JgAU+/o uP1Z7uOoo90M7XB+wYTzMvMUzpsNOnZzd86Nr0+cXdmrYMmghVSK3Q58HQj1WUpR iIIYc5kjc/WN2+YDUEtMrjxaDs69cBL6PJSbZc4tOXavFySFkXm8JvFGYpgRzSxG N43pbmdKwR8trJQRCs2SM2YeIoozyqNMAtETHeIingtv2p+sUyc+lY2TXhICcGNV e2y8aQ+hvVl6HT6iEJbb9qHi2jz5lOFWYE7sZ8SwdL+FDN+rNBqN81ssuiWe69SG AXFoCkivZWaYRUFAHdjP8J4ISihRKNlutrMxFy3hnaxlZAAxMmcTWg4zdBbB02mK 2+e+0HvwsUoPgBsOkRfiq0cC93X3SEQLNuAYGE7Xh8R/b8fpuA/pgaA1LLq3J8KP zZA1/9+ka6A= =7jd8 -----END PGP SIGNATURE----- --==_Exmh_1405631724_2078P--
