By the way @Aki does sony avail their circuit diagrams to consumers? ----- Original Message ----- | From: "aki" <aki275@gmail.com> | To: "Skunkworks Mailing List" <skunkworks@lists.my.co.ke> | Sent: Monday, December 5, 2011 8:28:27 PM | Subject: Re: [Skunkworks] Enable Sony Home Theatre play and recognize | proprietary formats | Nice one @Steve! The good old soldering iron and semiconductor days. | :-) | The encoder/decoder chips are locked in, this would be one very | complex task here in KE because the main controller chip picks the | file formats from the laser pickup unit and will reject any other | formats. This bus info is shared between the laser decoders, pre-amp | and sent to the demod chipsets, controlled from the main chip. | However, if @TheMburu can find us the circuit diagram of the unit, I | can point him to the chipset that needs to be replaced, along with | the main controller chip. Unfortunately none of the onboard chips | are re-programmable, due to model features. | This is like really old scholl stuff, nice to re-visit after many | years. | Rgds. | On Mon, Dec 5, 2011 at 8:14 PM, Steve Obbayi < steve@sobbayi.com > | wrote: | | Ok not sure about this particular device but depending on the type | | of | | microcontroller used for playback you may have to program the | | codecs | | right into it. unfortunately some microcontrollers are read only | | but | | thats is debatable.
