Hacking psp 1000 video out using this method possible???

aak · Jan 18, 2019

in early to mid 2000s there were some sony handycams with a special IR (infrared) technology known as super laser link.

you could wireless stream handycam video and audio to your television without the need for wires. Only handycams marked with laserlink had that ability (since they were IR blasters and also could recieve IR)

here is an example

i was wondering if something like this can be achieved with the psp 1000 as well. considering the psp 1000 came out same time as those handycams and no reason was provided for the IR blaster.

maybe thats what the IR is for. for streaming wireless video to tv

if someone with psp 1000 can experiment please do tell. thanks

IDK, but I have a 1000 and use remotejoylite which allows streaming to PC, and that PC is a laptop which is hooked up to television via HDMI. Works good and allows for controller used too. I use a wireless dual shock 3 with bluetooth.

i know that. im talking about official accessory use like psp 2000 3000 go component cables etc

psp 1000 doesnt have component or composite so maybe it runs on IR

Someone would need to write a driver (which would probably need CPU and memory intensive processing, for converting progressive video to the interlaced composite which was probably transmitted) - and I'm not even sure of the maximum data rate of the port! (if any)

No, there is no unused hardware video encoder (unlike in the Vita 1000)!

RemoteJoyLite is the correct answer. It's amazing, and before PPSSPP, it was by far the best way to play PSP on a TV, and it works with the 1000. I have a 2000 and was very disappointed by the tiny box the PSP plays in on the TV over component and the quality loss. Using the 2000 with component also required you to use the PSP as a controller, which was cumbersome with both having power and component plugged in. With RemoteJoyLite you can just set the PSP next to the PC and use whatever PC compatible controller or adapter you want.

The IR on the PSP 1000 can control TVs like a remote, which is nifty. I doubt it has the bandwidth to stream video or audio though, and IR requires line of sight, which is a massive pain for gaming. I have an IR wireless controller for N64, it was pretty bad.

IR interfaces usually do not have the bandwidth to transmit anything but small amount of data. They are ok for serial communications but not anything more. The Handycam in the video probably used specialized hardware only for that (and it must be paired with a matching receiver). Also IR need to be steady: often if you move the device you will loose beam alignment; not very useful if you want to play. There were 3 ways to have video out from a psp 1000: streaming thru usb (I have no idea of the lag); using a very convoluted mod that involves a lot of soldering inside the psp and an external docking station with video out and a plug for ps2 joypads (they were sold for a short period of time and they were very expensive)

or using an adapter like this one (basically a small camera mounted on top of psp screen):

anyways, the only good option is using a PC and RemoteJoyLite ~~or just buy a newer PSP~~. Personally, I use the wire for my Wii U Pro Controller as it's pretty long.

ok thanks for the replies

i am trying to find out from handycam owners that what IR is it thats allowing to trasmit video and audio since IR are only known to send small amounts of data with very short distances.

the hardware is easily available for super laser link (the receiver and handycam) but i can not find much information about the workings of the super laser link

IR are used in a lot of fields. The builtin interface you can find in most of the consumer hardware is, usually, only meant for transmitting small amount of digital datas but laser link infra red interfaces for trasmitting huge amounts of data on very long distances are a thing. Have a look to https://en.wikipedia.org/wiki/Free-space_optical_communication.

The Sony laser link probably is used to transmit analog video (as the reveiver only uses analog video). Have a look to this paper: it uses leds to transmit analog video up to 50 cm without using any customs optics. The circuits seems simple. Pair it with a ir laser diode (and some optics for a better alignment) and you will achieve much longer distance.

yes but if you read the research paper or the wikipedia article there seams to be no indication of such IR technology to be available to normal consumers (that transfer video and audio using infrared) in late 90s or early 2000s. and whatever is mentioned regarding high data stream travel using IR seems to be pretty expensive and something unique.
also both the articles are from early 2010s

even as of now the only tech utilizing such a thing and available to normal consumers are these old sony handycams
and the super laser link reciever.

also another thing to know is that i actually used it and the distance is 8 meters which is a lot for wireless transfer of video and audio using IR.
in other older devices using IR data transfer both devices had to be with 1-2 inches if each other. (example gameboy color)

The technology was available also to users, there are many project about using cheap laser pointers to send data.

My link it's just a start to look further on the web.
Commercial products for sending high data streams are not consumer oriented because... consumers do not need those. Also it's difficult to find info about was on the web in the late '90. You should check some old magazines about electronics, in your local public library. Not everything is on internet ;-)
Sony probably was the only one interested in this technology and, seeing how many laserlink receiver you can find NOS at a bargain prices, it didn't catch a lot. If you wanted to send a low quality composite audio and video stream you probably used an RF system, that most of the CRT TV with an external antenna can receive without additional hardware.
IR works only few inches because if you use LED. Switch to a laser diode and you can reach an higher distance. This is not a limitation of IR but a limitation of the device that emits the IR light. You can use also led with visible light, if you want. IR leds were cheaper and IR receiver less sensitive to interferences. In the end the laserlink was fancy but useless.

so the sony handycam uses IR with laser diode since the video transfer is 8 meters

also does anyone have a psp 1000 and can tell what happens when they press the display button for more than 5 seconds???

in psp 2000, 3000, and psp go press the button for 5 seconds switches to a black screen, then a grey screen with the video out display out and then the output goes to tv

what happens when the psp 1000 display button has held for 5 seconds or longer. just asking. thanks

If you press the screen button you change the backlight level. If you keep it pressed longer the screen shut down but the psp stays active. If you keep it pressed even longer nothing happens.

The psp 1000 completely lacks the video out hardware.

aak · Jan 23, 2019

oh ok thank you so much

aak · Apr 18, 2019

it seems that all psp have video out at least software wise

the biggest example is the existence of remotejoylite which allows streaming of psp to monitor

so technically video out can be done on psp 1000 using infrared (just like the sony handycams)

Do you understand just how much slower infrared is than USB? The Laserlink cameras were probably specially designed to be able to output through IR, but you know what isn't? The PSP.
