Hacking DPG video server and client like tversity

[maru487]

So in my quest for streaming movies to the DS I have found a couple of issues:

1. Wifi is too slow
2. DS can't handle the decoding

So unless I am way off, why couldn't a TVersity like server work with the DS to convert videos on the fly?

First problem:
802.11b is up to 11Mbits/sec but usually runs at 1-5Mbits/s.
An average DPG is 300 - 500MBytes, that would be 8*300 - 500Mbits = 2400 - 4000Mbits
An average movie length is 90-120 minutes = 5400 - 7200 seconds

So using the worst case of 4000Mbits and 5400 seconds you get:
4000Mbs/5400s = 0.74Mb/s

Thats 25% less then the worst case scenario of 802.11b. The DS wifi can can handle that just fine

Second Problem (decoding):

If the unit can decode a dpg, there should be no difference if it's a streaming DPG.

Anyone? This seems to simple for someone to miss, so I must be missing something?

well maybe it's just that no one has invented it yet, just like that N64 that streams over wifi, except this would be better as the input lag wouldn't matter near as much

Except that when the DS is downloading it takes away a little bit of the cpu vs playing a file locally. I am not sure what the overhead is, but I'm pretty sure this is the main reason why we dont see any streaming solutions on the DS.

I doubt that considering the wifi linked games that are available.

Although the amount of wifi data is less for games, the processor is able to handle all of the I/O from the user, the implementation of the game and data transfer.

If I knew how to code better then a few VBA scripts this is a project I would definitely take on.

Any programmers here that may know the reason or limitations?
