| 01:36.22 | MonMotha | landley: you can get parallel RGB to DVI PHYs reasonably easily. Hook that up to your framebuffer of choice. Not a single chip solution, but an option. |
| 01:37.21 | landley | MonMotha: a reasonably clueless end-user can get HDMI input to a $99 television. |
| 01:37.43 | landley | If the driver is in the vanilla kernel, a bootable CD or preinstalled image should recognize it and use it as at least a framebuffer. |
| 01:37.45 | MonMotha | landley: well, what are you looking for? "USB to HDMI"? |
| 01:38.06 | landley | Any solution that involves soldering parts together will have a grant total of maybe 3 dozen potential users in any given year. |
| 01:38.18 | landley | USB3 to HDMI would be idea. |
| 01:38.20 | landley | ideal |
| 01:38.29 | MonMotha | well, you seemed to be looking for a component level solution |
| 01:39.07 | landley | A component level solution could be put in a USB3 adapter pretty easily. And in stuff like raspberry pi. |
| 01:39.33 | landley | Or stuff like http://www.gizmag.com/samsung-galaxy-smart-dock/24820/ |
| 01:39.54 | MonMotha | well, if you've already got an SoC with an "LCD controller", you can probably just drop said DVI PHY down and have what you want without much trouble. |
| 01:40.09 | MonMotha | again, a component level solution, but not much trouble for the designer if you're trying to make something like a raspi |
| 01:40.15 | landley | History is swinging back around to "television as computer display". As in the 8-bit days, so in the smart phone. |
| 01:40.47 | MonMotha | I suspect that dock is largely passive. The note already has an HDMI output on it, IIRC. |
| 01:40.52 | landley | Does it produce output you can plug into a generic television from Target? |
| 01:41.15 | landley | HDMI output in the phone would be great, I thought the power consumption would be too high. |
| 01:41.18 | MonMotha | it'll do whatever you configure the "LCD controller" to which, if TV compatible, yes, will work on a TV |
| 01:41.27 | landley | USB solution has the advantage that you already have to plug the phone into USB to charge it. |
| 01:41.43 | MonMotha | well, that's why they do the docks - it connects both USB for power AND the HDMI |
| 01:42.00 | landley | Exactly. |
| 01:42.08 | MonMotha | but most of them have a micro-HDMI port on them, too |
| 01:42.27 | MonMotha | you can just plug a standard cable in and be done if you don't mind running the device on battery or plugging in a separate USB cable for power |
| 01:42.30 | landley | minimum: keyboard, mouse, power, video. |
| 01:42.37 | landley | Having them be separate connectors gets darn fiddly. |
| 01:42.53 | landley | USB is just one plug that can do all 4. Hence: usb. |
| 01:43.13 | MonMotha | keyboard and mouse are going to be bluetooth in most scenarios these days. It seems rare to find a tablet with dedicated USB hosts nowadays, though you can do dual role and hook up a hub that knows how to provide power back to its host. |
| 01:43.33 | landley | tablet isn't phone. |
| 01:43.36 | MonMotha | video is tough just due to bandwidth. Superspeed USB is fast enough, but I'm not seeing it on smart phones yet |
| 01:43.42 | landley | Tablet is nice, but the phone is with you 24/7. |
| 01:43.52 | MonMotha | well, you're definitely not going to see multiple USB host ports on a phone |
| 01:43.54 | MonMotha | not enough room |
| 01:44.02 | landley | MonMotha: you only need one. |
| 01:44.07 | landley | USB has hubs for a reason. |
| 01:44.15 | MonMotha | so if you want USB devices plugged in plus power back to the phone, you'll need an OTG aware hub |
| 01:44.18 | MonMotha | and those are rare |
| 01:44.30 | MonMotha | but the standards are out there |
| 01:44.52 | MonMotha | there's also a standard for full motion uncompressed video over USB, IIRC |
| 01:45.12 | MonMotha | it was kinda useless in the past since high speed USB wasn't fast enough for any realistic use |
| 01:46.01 | MonMotha | sadly, Android's support for host-mode USB is kinda crummy |
| 01:46.19 | MonMotha | I don't know if iOS has any at all - no Apple devices running it have a capable port, IIRC |
| 01:46.56 | MonMotha | and you'd need a breakout cable on iDevices, anyway, so you might as well just run displayport or HDMI/DVI physically and let people plug that in |
| 01:47.02 | MonMotha | since that's where it's going eventually, anyway |
| 01:47.31 | MonMotha | FWIW, displayport could fix this, too |
| 01:47.58 | MonMotha | there are provisions for back-powering the host (though you'd need a special cable), and it can carry USB in the aux channel |

| 05:21.51 | _av500_ | new androids will all get Wifi display I think |
| 05:22.01 | _av500_ | at lest QC is pushing that |
| 05:22.04 | _av500_ | least |
| 05:22.22 | _av500_ | and ti was when they were still interested in mobile |
| 05:27.03 | MonMotha | Is it actually wifi? There's no way that will be full motion |
| 05:27.23 | MonMotha | or is it UWB on 60GHz or similar? |
| 05:27.24 | _av500_ | it is |
| 05:27.32 | _av500_ | h264 compressed |
| 05:27.41 | MonMotha | ah, well, that causes other problems |
| 05:27.45 | _av500_ | yes |
| 05:27.52 | _av500_ | but, its for consumers :) |
| 05:27.54 | MonMotha | true |
| 05:28.02 | MonMotha | I'd like to see UWB wireless video take off |
| 05:28.06 | _av500_ | theyare happy to see utub on the big screen |
| 05:28.15 | _av500_ | MonMotha: I've see a 60ghz demo |
| 05:28.18 | _av500_ | seen |
| 05:28.29 | _av500_ | its wireless PCIe |
| 05:28.31 | MonMotha | remoting video from laptops, tablets, phones, etc. to large fixed screens (projectors, TVs, etc.) is neat |
| 05:28.37 | _av500_ | they had the gpu on the other end |
| 05:28.43 | MonMotha | you wouldn't have to do it that way |
| 05:28.50 | MonMotha | there's bandwidth for a full rate framebuffer |
| 05:28.53 | _av500_ | also the HDD and NIC |
| 05:29.05 | MonMotha | though that could be handy for other applications |
| 05:29.08 | _av500_ | its nice to dock a phone/phablet |
| 05:29.12 | MonMotha | right |
| 05:29.13 | _av500_ | "dock" |
| 05:29.36 | _av500_ | and its very short range, line of sight |
| 05:29.46 | _av500_ | can have one at each desk :) |
| 05:29.51 | MonMotha | I'm just thinking it would be nice to be able to just set my tablet down on a podium in a conference room, tell my tablet "clone the display to the receiver built into the podium", and I'm giving a presentation |
| 05:30.01 | _av500_ | wifi display |
| 05:30.12 | _av500_ | new android 4.2 API allows to have a 2nd screen |
| 05:30.15 | MonMotha | no weird drivers needed, etc. Just need to negotiate framebuffer formats, and there aren't TOO many of those |
| 05:30.25 | _av500_ | if you app is aware, it can send the pres to the remote display |
| 05:30.29 | _av500_ | and keep UI and notes local |
| 05:30.34 | MonMotha | well, that would be great |
| 05:30.45 | MonMotha | I'm just thinking it needs to be as dumb as possible to be accepted |
| 05:30.48 | _av500_ | work ovr both, hdmi and wifi display |
| 05:31.04 | MonMotha | witness how few people give presentations with e.g. Powerpoint (much maligned as it is) using the split presenter/presentation view |
| 05:31.35 | _av500_ | last one I gave I pointed acroread to a pdf in the cloud |
| 05:31.44 | MonMotha | I tend to just use PDFs, too |
| 05:31.56 | MonMotha | though I just drop evince or similar on the projector |
| 05:32.00 | _av500_ | saved me from bringing even a laptop |
| 05:32.04 | MonMotha | well, the output hooked up to the projector |
| 05:32.13 | MonMotha | but it would be nice to be able to do that from e.g. my phone |
| 05:32.18 | _av500_ | sure |
| 05:32.19 | MonMotha | though my phone's PDF reader sucks... |
| 05:32.25 | MonMotha | I'm not big on this "cloud" thing |
| 05:32.30 | MonMotha | I've gotten burned by vendors too many times |
| 05:32.32 | _av500_ | if your phone has hdmi and you get 4.2, you can do it |
| 05:32.41 | _av500_ | MonMotha: cloud was my personal webspace :) |
| 05:32.43 | MonMotha | heh, my phone is 3 years old :) |
| 05:32.49 | MonMotha | ah, well, that's acceptable then |
| 05:32.52 | _av500_ | thus it does not exist |
| 05:32.56 | _av500_ | get a N4 |
| 05:33.19 | MonMotha | heh, actually, it's still amazingly popular since it was, until very recently, the highest end slider keyboard phone Sprint would permit on their network |
| 05:33.27 | MonMotha | and say what you will about Sprint, but the price is right |
| 05:33.38 | _av500_ | chuckles at "permit on their network" |
| 05:33.43 | MonMotha | it's sadly true |
| 05:33.52 | _av500_ | "land of the free" :) |
| 05:33.53 | MonMotha | Sprint will only allow handsets they sell on their network |
| 05:34.11 | MonMotha | they're the only major carrier doing that (Verizon will give you the run-around, but they will eventually let basically anything physically compatible on) |
| 05:34.14 | _av500_ | you are free to build your own phone network :) |
| 05:34.18 | MonMotha | I know |
| 05:34.30 | MonMotha | and I've considered getting some WiMax gear or similar |
| 05:34.39 | _av500_ | its called LTE now |
| 05:34.45 | MonMotha | LTE is crazy expensive |
| 05:34.58 | MonMotha | 802.16 gear can be had at somewhat reasonable prices |
| 05:35.13 | MonMotha | and you can do full QoS'd voice over packet on it (need not be VoIP) |
| 05:35.39 | MonMotha | 802.16 gear is also easier to get on frequencies that don't require billions of dollars to license in the USA |
| 05:40.44 | _av500_ | ah, so you are building your own network :) |
| 05:46.38 | MonMotha | not really |
| 05:46.41 | MonMotha | but it's an option |
| 05:47.07 | MonMotha | I actually am helping somebody set up a wISP, but he's using 802.11n for most things just because it's so much cheaper |

| 19:17.02 | prpplague | is filling out his CV |
| 19:17.24 | chouimat | still fighting with a badly coded firmware ... trying to figure out the problem with the codec ... |
| 19:17.54 | chouimat | and fighting a really bad cold too |
| 19:23.26 | Spida | had an incident with badly coded firmware in his holidays. sparate elevator call buttons for upward/downward. and a LARGE sign warning not to push both buttons. guess what happens when you do... |
| 19:23.58 | chouimat | hehehe |
| 19:29.24 | landley | spida: what happens? |
| 19:38.46 | Spida | landley: the elevator is not allowed to go either upward or downward. |
| 19:38.57 | Spida | it justs stays where it is |
| 19:40.18 | landley | Spida: does this time out? |
| 19:41.14 | Spida | no clue |
| 19:41.22 | Spida | hotel staff fixed it |
| 19:41.50 | Spida | i guess they just pulled the fuse |
| 19:42.09 | landley | This strikes me as a thing they might want to fix. |
| 19:42.09 | keesj | where can I get a job coding bad firmware? |
| 19:42.17 | landley | Presumably, the elevator has a service company. |
| 19:43.03 | keesj | wow that't really bad. |
| 19:44.09 | roxfan | i suspect the incident rate went up after they added the warning :) |
| 19:44.13 | Spida | they had large signs, 20cm by 30cm telling everybody not to do it. |
| 19:44.18 | chouimat | keesj: don't. since you might piss off all the people that will get paid to fix it |
| 19:44.23 | Spida | that was their fix. |
