OSD 2.0 Product Specification

Codename Project “Archiver II”

NOTE: the specs below are information about the OSD2 as a consumer product.

There is a separate page about the OSD2 Developer Kits

The OSD 2.0 is roughly based on the Archiver concept, the overall spec is,

  • up to 720p/XGA (1024x768) MPEG4 encoding + AAC/AC3/MP3 encoding
  • up to D1(720x480) H.264 encoding + AAC/AC3/MP3 encoding
  • 720P MPEG4 SP playback, up to 1080i with certain content
  • Support H.264, MPEG2, MPEG4 codec playback with upscaling
    • DivX/XviD as phase two SW integration
    • WMV as possible phase two SW integration
  • Composite/Component Input
  • 2 composite input, 1 component input
  • all with dedicated stereo audio
  • Composite/Component/HDMI Video Output
  • composite and component share the audio output
  • RCA Audio I/O
  • Wifi through USB
  • Internal 3.5 Hard Drive with SATA interface
  • 2 USB ports in rear, 1 in front, and 1 internal to housing



The OSD 2.0 will be based on the Texas Instruments Davinci 6446 chipset, but will attempt to leverage existing investments in application software and testing as much as possible.

Mother Board

The OSD 2.0 main board will comply with the Mini-ITX form factor. Although the IO of the OSD 2 is different than a PC motherboard, the idea is that an interested hacker can put the device into a computer case if they desire to add additional peripherals that are not supported on factory configuration (optical disc drive, etc).

On-board memory:

  • NAND: 256MB
  • RAM: 256MB

Internal Storage

The OSD 2.0 will support one internal ATA-6 3.5” HDD drive with PATA interface.

PATA/IDE drivers are getting harder and harder to find, OSD2.0 will use a PATA to SATA bridge internally to support PATA drive.

Power Supply

NOTE: THE OSD2 REQUIRES A 12V POWER SUPPLY. THE HOUSING MISTAKENLY SHOWS 5V The system power supply is able to power a complete system including one hard disk drive. Devkit Power supply is external to the housing (like a laptop power supply).

  • INPUT: 100-240V, 1.5A, 50-60Hz
  • OUTPUT: 12V 4.1A (50W Max)
    • Output plug is 10.5mm long OD 5.5mm and ID 2.1mm
  • Supply cord will use a C7 connector for flexibility for international users



There is component, composite, and HDMI interfaces available.


  • Composite Video Input
  • 1 RCA jack on front panel for Input 1.
  • 1 RCA jack on the rear panel for Input 2.
  • All RCA jacks for composite video will be colored yellow.
  • Component input
  • 3x RCA jacks on rear for Input 3.
  • Y, Cb and C RCA jacks will be colored green blue and red.

Video Output

SD and HD video output will be mutual exclusive, thus a dedicated Remote Control button (video output) will be designed in to allow user switch real time.

  • Composite output
  • 1x RCA jack on rear panel. Jack shall be yellow.
  • Component output
  • 3x RCA jacks on rear panel.
  • Y, Cb and C RCA jacks will be colored green blue and red.
  • HDMI
  • 1x HDMI output jack on rear panel.
    • HDMI 1.1 or later
    • HDCP not required


Audio Input

  • 2xRCA jacks on the front panel for input 1
  • 2xRCA jacks on rear panel for input 2
  • 2xRCA jacks on rear panel for input 3

Audio Output

  • 2x RCA jacks on rear panel for stereo output.


  • 1xUSB jacks on the front panel
  • 2xUSB jack on rear panel.
  • 1x USB port internal to housing

* an internal USB hub will be used to support above multiple ports.


  • 1xSD/MMC multicard slot support on front panel

No CF/microdrive: this is too expensive and very infrequently used, Memory Stick is not supported by Soc. SD-HC will be supported by SW update.


  • 1x RJ-45 Ethernet jack on rear panel
  • built in support for Wifi accessory through USB Wifi Dongle

IR Blaster

  • Mini-jack compatible with OSDv1 on the rear panel.


  • 2.5mm headphone jack mounted on rear panel (same as the IR blaster jack).


  • No video pass-through support, live with the composite video degrade and component/HDMI output will not be user noticeable.

(Q: will pass-through occur when unit has no power? Will pass-through be enabled during boot sequence?)

User Indicators

  • 2 LEDs on front panel, each LED has 2-color states: Red and Green.



The OSD 2.0 will be enclosed in a plastic housing with accommodations for consumer-installed internal HDD and USB peripherals. Housing style to physically fit within the device stack of common entertainment center furniture. Housing style to have a unique quality while being visually congruent with modern entertainment center equipment (DVDplayers, VCRs, Tivo, etc.).


Dimensions approx. 60mm(H) x 250mm (W) x 250mm (D)


OSD 2.0 will be marketed as a video archiver. There are multiple ways that a user can get content onto the device, but perhaps most commonly this will be done via recording from analog inputs (from sources such as DVD players, VCRs, satellite and cable tuner boxes, etc.).

OSD 2.0 is expected to support a variety of formats and containers as outlined below. The OSD2 is currently in development, for schedule and milestones, see OSD2_Development_Milestones
