Apple TV - What we know so far.

[Swad]

I thought it'd be a good idea to start off this forum with a list of all the hardware info we can gather - pictures, hardware ID numbers, etc. Post your info in this thread and I'll update this first post as necessary.

 

Hardware:

• 1.0GHz Intel Pentium M-based "Crofton" CPU, based on SSE2 Dothan model # 7645A966 0159
  
• NVIDIA G72M graphics with 64MB DDR2 memory
  
• 256MB of 400MHz DDR2
  

Software:

• Modified version of OS X 10.4.7 along with some 10.4.9 kexts
  

Firmware:

• Apple TV uses EFI, based on the presence of the hard drive in GUID map.
  

Communication:

• TCP port 3689 is used to communicate with iTunes while using the iTunes Library Sharing feature.
  
• UDP port 5353 is used by Apple TV for automatically finding computers with iTunes on your network using Bonjour.
  
• TCP port 80 and 443 are used for basic and secure communications with the iTunes Store via the Internet.
  

Formats:

• H.264 and protected H.264 (from iTunes Store): Up to 5 Mbps, Progressive Main Profile (CAVLC) with AAC-LC audio up to 160 Kbps (maximum resolution: 1280 by 720 pixels at 24 fps, 960 by 540 pixels at 30 fps)
  
• iTunes Store purchased video: 320 by 240 pixels or 640 by 480 pixels
  
• MPEG-4: Up to 3 Mbps, Simple Profile with AAC-LC audio up to 160 Kbps (maximum resolution: 720 by 432 pixels at 30 fps)

(from Apple Insider and other places)

 

1.0GHz Intel Pentium M-based "Crofton" CPU, based on Dothan. model # 7645A966 0159 (SSE2, so many OS X basics to add will probably need to be from hacked binaries we use now)

 

NVIDIA G72M graphics with 64MB DDR2 memory

 

256MB of 400MHz DDR2

 

 

 

Also, from apple:

* TCP port 3689 is used to communicate with iTunes while using the iTunes Library Sharing feature.

* UDP port 5353 is used by Apple TV for automatically finding computers with iTunes on your network using Bonjour.

* TCP port 80 and 443 are used for basic and secure communications with the iTunes Store via the Internet.

 

Why would the Apple TV need a secure connection to the iTunes Store?

[macFabri]

I just got my ?TV yesterday. I will replace the HD to one i have ( 100GB ). I also have new Airpot Extreme and have my entire iTunes library in a USB hard disk plugged on it.

 

Im wondering if we can create an Alias on ?TV to read the files directly.. so we dont need to worry about space there.

 

I will try it when i back from work tonight.

[asap18]

Swad, we know it uses EFI to boot since its hard drive is in the GUID map.

[Colonel]

Here's an image of Firefox (Most likely 3.0 Alpha) on AppleTV taken from the SomethingAweful thread.

 

And here's a picture of iTunes and VLC running on AppleTV. Also taken from the SomethingAweful thread.

 

If this thing can run Firefox, iTunes, and VLC, we know it's got OS X.

[Soündless]

if someone could make a mac osx install dvd for this, i might actually buy one, i am going to the apple store this weekend, so i can ask them what os it runs

[asap18]

It runs a stripped down version of 10.4.7 and it seems to have a few .9 kexts.

 

Also whats weird is that even with a geforce go 7300, qe is "not supported" while core image is.

 

We need some iokit programmers to enable that usb port. = elgato tv tuner = ultimate htpc.

[Swad]

Would there be any way of installing OS X while connecting the HD to a Mac, then reconnecting to the Apple TV?

[mifki]

Yeah, just image your drive across if you want, replace the kernel and the kexts, should work afaik

[Colonel]

Not quite. Remember, AppleTV has an SSE2 processor meaning that we'd need to "hack" some of the core files to work on it.

[ampTK]

The standard OS X wouldn't work, because of the CPU, but a hacked version (for intel with SSE2) without the BIOS hack (probably wouldn't need the TPM workaround either), and maybe with the iTV kernel and/or some of its kexts just might

 

We know that macFabri has an AppleTV, anybody else?

Edited March 24, 2007 by ampTK

[mifki]

Well we just checked, the aTV has karma , and colonels. image a sse2 install

 

EDIT: uname on aTv

 

Darwin appletv.home 8.8.2 Darwin Kernel Version 8.8.2: Mon Jan 29 18:57:29 PST 2007; root:xnu-792.94.18~1/RELEASE_I386 i386 i386

 

EDIT: it turns out there is no sse3 emulator on the aTV

[macFabri]

We know that macFabri has an AppleTV, anybody else?

 

Yes and Im able to try and make any tests. I will just change the HD today to bigger one. After that i can play with the original HD. Just let me know what you guys want me to do.

 

I think i have all hardwares we will need to try anything.

[mifki]

Weird, there is no mach_kernel on the atv, only a mach_kernel.prelink file

[Workplace Shell]

Image courtesy of TechRestore, there are two Automator action scripts for audio and video capture (likely future enhancement for recording capabilities?).

[Dragon]

OS X running on SSE2 WITHOUT emulation??

It would be nice to get a backup image of original drive in iTv can you do it?

[tayklor]

sorry about the Leo thing.

 

dos anyone know if the AppleTV has a finder on the HD?

[Embio]

OS X running on SSE2 WITHOUT emulation??

 

excellent point that no one else has mentioned, Dragon - would be good to compare Apples way of doing things to the communities way

[ampTK]

EMBIO, Why would apple need SSE3 emulation, it's their software, they can make so it doesn't need SSE3.

[Colonel]

sorry about the Leo thing.

It does not.

[mactijn]

For information gathering, we set up a wiki. You can find it at http://wiki.awkwardtv.org/

 

Also, there is a major collaboration effort going on on IRC. See the wiki for more details.
