[HDMI2USB #6] Create EDID database website + scripts for EDID information recorded by HDMI2USB device

Hi. I'd like to take this ticket, can you give more specific information about this issue?

[mithro]

Information about EDID can be found at http://en.wikipedia.org/wiki/Extended_display_identification_data

Despite EDID information being important in telling the computer how the display works, many devices ship with bad or misleading EDID information. We'd like to collect that information in a website.

The website should support basically cataloging and displaying EDID information and support people submitting new EDID that they have captured from their devices (either through the HDMI2USB device or another tool).

[Juggerr]

Okay. There are few questions that I'd like to clarify:

1. This website should be an another Django app inside of existed Django project (website)
2. Some use case questions: Users can upload their EDID files and they should specify their device info e.g. (manufacturer name, device name, device type etc.) Than other users can go to the site and select a device's EDID file which they need. Selection should be as hierarchical selector i.e. first, user should chose manufacturer, than type, than resolution .... Have I understood the task right? And I ask you provide me fields by which devices would be specified.

[mithro]

1. This should be a new totally separate Django website.
2. The manufacturer name, device name, etc should be extracted from the EDID information. For extracting the information take a look
   • Take a look at https://gitorious.org/sigrok/sigrok/blobs/master/libsigrokdecode/decoders/edid/edid.py
   • http://www.polypux.org/projects/read-edid/
3. People should be able to "correct" the edid information.

People don't really need to download EDID information. You need to look at the EDID information for possible fields.

Okay. How you advice me to parse EDID format? The first links that you gave me, that project doesn't support EDID format (their decoder accepts some session format from their devices, they said this function is expecting for implementation, but unavailable now). Probably I should call "parse-edid" utility (the second link) and may be I can adjust this program for our facilities. Or should I write own script for parsing?

[mithro]

You'll probably want to parse the EDID information yourself, it's pretty trivial really. Take a look at the struct library in Python.

[Juggerr]

Well, I have done something. It is not fully ready yet, but you can take a look something. I have created Django website. https://github.com/Juggerr/web_edid

• On the index page, there is link to upload page (I have put some samples of EDID files if you don't have (directory - edid_samples ) ), and also there will show EDID files which devices we already have (there are just list yet, without any choose widgets or/and search).
• On the upload page users can edit their EDID files, and than submit.
• I haven't wrote parsing of all fields yet (but you can see the basic workflow of site with the existed fields)
• So I have created basic functionality of the site, you can check it and say that I need change, correct, add etc.
• In further I will be adding more fields in the parser.

[mithro]

Looks like a pretty great start! I'd like to add a bunch of comments to your code, can you please send me a pull request?

Things to put onto the TODO list might include;

• Ability to search, IE get all monitors made by Dell.
• Ability to tag EDID files.
• Ability to group EDID files in some way, IE they might all be made by Dell but one is "Dell Corporation" and another is "Dell Limited".

This task was completed by @sewar as part of the Google Summer of Code in 2013. The new code can be seen at https://github.com/timvideos/edid.tv and https://github.com/timvideos/edid_grabber_c and the website is live at http://edid.tv
