PS Vita Video Out: Initial Analysis
I’m sorry readers. It’s been a while since you’ve heard from me on my PS Vita video out endeavors. I’ve been bus with travelling, gaming, and other tasks. I’ve actually had this update ready for you guys for almost a month, but just couldn’t find the time to write it.
The most practical way to go about this project was to use something that we already have, and make something out of it. On the PS Vita, there is a MIPI signal that is readily utilizable (the signal that the 3dsvideocapture guys use). The signal used for HDMI is a TMDS signal. Thus, we wanted to convert a MIPI signal to a TMDS one.
There were two problems that were encountered during the analysis.
How Practical Is It?
Despite what some of you would prefer, this most likely isn’t going to be plug-and-play. You will have to do some installation yourself. Maybe some simple soldering, but probably not much. I would love it as much as you would to not have to do work to get video out on my PS Vita, but it’s the reality of the situation that makes it so that you’ll have to.
Cost (Production and End-User)
This is probably the most important factor of the entire project. Here are the factors for the cost of producing the hardware for the mod.
- Cost of the converter chips
- Development board
- Spare Vitas for testing
- Miscellaneous bits for each board
- Shipping and customs charges
- Software development time
All of this will add up to upwards of $125k, and a very uncertain investment.
The cost for the end-user isn’t set yet, but there is a goal. Ultimately, the cost of the whole the mod should be less than that of a PlayStation TV (Vita TV). Especially so if Sony lets us play all of our games.
The thing is, it may seem like this is it, but there is more. I have a hunch on another way to approach this. I’m not sure if it will work, but if it does, the cost will rocket down, and the practicality will improve.
On a side note, I’m currently holding a $10 US PSN code giveaway. If you’d like to enter, click here.
Special thanks to Josh_Axey for figuring a lot of the factors and costs.
