Updated 1/17/2011- Block diagram for board. Please review and provide feedback.

OSD3 Overview

The OSD3 is intended as an open set top box that allows users to view internet based media content using their home media center as well as capture media content and record it for later playback. The OSD3 seeks to merge the capabilities of the popular OSD1 platform with the Neuros LINK to provide a full high definition solution while remaining open for customization. Neuros believes that you should be in control of your own media content and is creating the OSD3 to give you that control.

The OSD3 will be based on the next generation digital media processor from Texas Instruments. This processor is a System on Chip (SoC) processor that integrates many components required for digital media as well as a high speed ARM based GPP running Linux.

  • PCIe
    • This may be a standard connector or an edge connector. More details to follow.


Many of the software details are still too early to tell but we will update this section as we learn more. What we do know is that the OSD3 will be a no-compromise Internet TV box with high performance playback of full-fledged Adobe Flash and HTML5 video.

We have heard rumor that Texas Instruments is planning to release a simulator for this chip later this year which can be used to develop software prior to the release of the actual silicon.

How Can You Get Involved?

This early in the product cycle we want to know what you think. Post your thoughts about the OSD3 to the OSD3 topic on the forums. Let us know what you want in an open set-top box. We can't guarantee it will all be there, but asking never hurts.

As we move forward and more tools and hardware become available you can always help us in developing/porting cool software to the OSD3 platform. Let your imagination run wild here, the OSD3 is an open platform so you can do what you want.
