Vydeo : Aries | DV to BT.656

DV to BT.656 SUBMINIATURE CONVERTER

Aries™ is a ITU-R BT.656 to DV over 1394a encode/decode video format converter, designed primarily as a subassembly for integration into OEM equipment.

Vydeo has designed the Aries module as an integrated approach to fast path, seamless and straight-forward integration into system architectures, providing low cost, key conversion functionality.

Vydeo engineering provides technical support, sample source code and an API to OEMs to expedite bring-up and also, provides hands-on assistance in programming.

The AVC code base used in Aries is available for licensing.

_PRODUCTION VERSION MODULES


	^{Aries Production Version Module (Top)}

	^{Aries Production Version Module (Back)}

Implementation of Aries introduces Digital Video (DV) over 1394a functionality to existing or new product platforms. Leveraging Vydeo's easy-to-integrate Aries design allows OEMs to add key features in order to quickly refresh a product family, either as a standard offering or as an upgrade. Often, renewing, upgrading and/or adding new functionality to legacy equipment that has already had all development costs fully amortized can be highly profitable.

Aries modules for development purposes are delivered with an API and sample source code to assist qualified OEM customers in setting up the integration and initialization of the module.

Detailed hardware and software specifications are available upon request.

_SPECIFICATIONS

The Aries encode/decode board is a small form-factor, 3.3V module that accepts an ITU-R BT.656 (8-bit) compliant signal, processes and converts to DV over 1394a. Aries™ also converts DV25 over 1394a to BT.656 (bidirectional).

The audio interface is I²S. Audio (32 KHz, 12 or 16 bit; 44.1 KHz, 16 bit; and/or, 48 KHz, 16 bit) can be processed or truncated.

Aries supports audio/video sync as well as auto-recovery on 1394 bus disconnection. PAL and NTSC and are auto-detected on the 1394 side and switched accordingly.

_I2C BUS

This flexible and programmable module also features an I²C bus as well as available system-level TTL level Tx and Rx. Vydeo supplies the I²C command set for the base set of functions such as: Stop/Pause/Fast Forward/Fast Search/Rewind, etc.

The board's processing engine is configured as an I²C slave for simplicity in system architectures. Aries provides I²C address pins that allow the host to programmatically select the I²C address of each Aries module in the system. Aries' highly integrated digital video codec's AV/C protocol processing does all the work to setup and manage video and audio data transfers.

_INTERFACE AND INTERCONNECTS

Vydeo has designed and deployed an off the shelf 3M interconnection system that has terrific flexibility for our OEM customer’s designs. These are low cost, low profile, .050" pitch, industry standard interconnect solutions.

Depending upon the internal packaging requirements of our OEM customer's systems, Aries can be configured to be plugged directly into a motherboard, or positioned elsewhere and connected via a low-cost flat ribbon cable assembly.

This system provides very flexible interconnect methods for both domains.

Aries may be purchased in numerous configuration versions, ranging from a low profile, 9.2mm version to the low cost standard product, 14.2mm in height off the motherboard. Board to board and board to cable interfaces are also available. A dual layout on the motherboard can be done to accomodate both the standard and ultra-low profile interfaces.

Various connector mating heights can be selected to accomodate standard or metric stand-offs.

The board is 95.25mm x 76.2mm.

Specifications, detailed pin-outs and prints for these connectors are available upon request.

_AVAILABILITY

Aries is a mature product and has long been released to production as an OEM build to order device. Aries is sold as a board-level only product to qualified OEMs. Production minimum order volumes apply.
