 Posted: Thu Nov 27, 2008 12:43 am Post subject: Hacking the 1Seg audio codec |
 |
|
Hi, I live in Brazil and digital TV was just released here. Well, if you try to use the 1Seg receiver here you can watch all the channels just fine, but there is no audio, since the codec used here is different from the Japanese standard.
My question is: Is it possible to hack into the 1Seg module and alter (or add) a new codec? |

| Yes, but pretty much beyond any feasible effort. Basically no one will do it. |

If by effort you mean porting the codec, it will be easier since the codec is open source. My main problem right now is the "how" part. How and where should I Start? Which modules should I look into? (ignoring the coding and setup part). |

No one has bothered to figure out the interfaces to the Sony PRXs. Its the same reason we don't have custom music_plugin.prx with support for more codecs etc. |

| Got your point. Where I can get more technical information about this? (the prx and how to append / analise / whatever code to it) |

| there isnt any information about the audio/video player prxs. youll have to reverse them yourself to see what functions they export for utilizing them. then youll need to make a decoder prx for your codec and wrap it with the samd functions. a herculian task as there are 100s of exports and the nids havent even been cracked. |
