Q10 10 Channel PCI RF QAM
The Q10 PCI Quadrature Amplitude
Modulator (QAM) Host Bus Adapter (HBA) is the newest member of the Company's
VDOProTM family of high performance, low cost per stream MPEG
transmission devices for open system Video on Demand (VoD) servers.
The VideoPropulsion Q10 provides 10 QAM channels
in two sets of 5 adjacent channels. Each channel is capable of
up to ten 3.8 Mbps SDTV, three 12.9 Mbps EDTV, or two 19.4Mbps HDTV streams
when configured to use Annex B.
Integral upconversion to RF output provides the ultimate in flexibility by
eliminating the need for external upconverters and messy cabling.
An onboard JAVA engine substantially reduces host CPU overhead leaving more
CPU cycles for your application or denser integration.
Software drivers are available for the Sun Solaris, Windows, FreeBSD,
and Linux operating systems allowing you to choose from a large variety of
computing environments.

The Q10 hardware and device drivers collect and multiplex MPEG-2
transport streams directly from host memory. The resulting multiple
program transport streams are transmitted with upconversion using 16QAM,
32QAM, 64QAM, 128QAM, or 256QAM modulation with variable symbol rates up
to 7 Msymbols/second. Forward Error Correcting (FEC) encoding complies
with ITU-T J.83 Annex A (DVB/DAVIC/EuroDOCSIS/IEEE802.14), Annex B
(DigiCipherII/SCTE/DOCSIS/IEEE802.14), and Annex C (Japan).
VPiTVTM Libraries, VideoPropulsion's standardized application
interfacing software, enables developers to build interactive VoD applications
across a multi-vendor server environment. Customers can select from a
broad range of interconnect hardware and use a common application program
interface (API) which supports a fully heterogeneous server environment
for the most popular operating systems: Linux, Windows (2003/XP), Solaris
(SPARC, x86), and FreeBSD.

Driver Support
The VideoPropulsion Mux Drivers for the Q10
use a highly efficient patent pending
architecture for precise timing. Designed to automatically detect and
configure to the hardware, these drivers offer numerous options to
users. The driver accepts any combination of single program transport
streams (SPTS) and multiplexes
them into a single, multiple program transport stream (MPTS). The streams
must be Constant Bit Rate (CBR) encoded and may contain embedded PAT, PMT and
PCR data. The product is capable of remapping PIDs and restamping PCRs as
needed for the multiplexing. Included with the driver are sample programs and
their sources for guidance in using the API to interface with higher level
applications. The Q10 API is compatible with the API used on other
VideoPropulsion products providing integrators with the flexibility to solve a
myriad of customer needs with a minimum of effort.
