MPEG4 Encoding Hardware - Device Driver and SDK porting to Linux
The Customer
The customer is a pioneer and market leader in broadband media gateways and
MPEG-1 and MPEG-2 encoding and streaming platforms. Propelled by sophisticated
technology and market expertise, its products are at the core of professional
digital video solutions worldwide.
The customer is a technological leader in its field with core competencies in
MPEG encoding/decoding and bridging between DVB and IP networks. Leveraging this
expertise, the company has developed technologies for transcoding, multiplexing
and IP/DVB conversion, all of which are integrated into its highly valued range
of products. In the enterprise domain, the Company's MPEG encoding/decoding and
streaming platforms facilitate video distribution over corporate LANs and
WANs.
Its media gateways create new opportunities for operators and telcos by enabling
the delivery of value added services such as TV over IP, personalized rich media
services and interactive TV, to residential users.
The Product
The product is a Low-Profile PCI MPEG-4 encoder card, which can capture and
compress two simultaneous audio/video streams, offering high-quality video at
low and midrange bit rates.
Developers who want to develop digital video-based applications can profit from
the Software Development Kits (SDKs), which offer a multi-feature cross platform
scalable development environment for digital video applications.
The Challenge
Ximpo Group's Networking/Media Streaming and Kernel experts were hired
to develop the Linux Kernel driver for the encoder, and to port the SDKs from
Win32.
The Linux Kernel driver was developed based on technical information from the
DSP manufacturer, and a "Reference Implementation" of a driver from the
evaluation board of the DSP manufacturer.
The SDKs were ported from the customer's Win32-based version, and included
implementing an "abstraction layer", to enable managing a single code-base for
both Win32 and Linux versions of the SDK, and as a preparation for future
portings to other OSes.
In order to reduce the learning curve required from the customers' R&D
personnel, the "abstraction layer" exposes an interface extremely similar to
the Win32 SDK.
Ximpo Group is providing to this project, through a multi-year support
contract, maintenance, support and ongoing development for the lifetime of the
product.
The product's marketing spans over 40 countries through a combination of
direct sales, independent distributors, authorized resellers, system integrators
and OEM partners. Worldwide technical support is being provided to customers
with on-site, e-mail, telephone and fax assistance.
