C1LP Low Profile PCI RF COFDM Modulator
The C1LP Low Profile PCI Coded Orthogonal Frequency Division
Multiplexer (COFDM) adds depth to our customers' applications by
incorporating new technologies that allow extended flexibility to configure
unique solutions.
The VideoPropulsion C1LP provides a COFDM RF output from a single or
multiple program transport stream supplied to the card via DMA. Integral upconversion
to RF output provides the ultimate in configurability, eliminating the need
for external upconverters and messy cabling. The C1LP supports both DVB-T and
DVB-H.
Product Highlights
- COFDM RF output with 6, 7, or 8 MHz bandwidth
- Upconversion to 50 - 860 MHz RF output
- Support for DVB-T and DVB-H
- API compatible with VDOPro multiplexing products
- Patented JAVA micro-engine architecture
- PCI Version 2.2
- Full power-up and service diagnostics
The C1LP hardware and device drivers collect and multiplex MPEG-2
transport streams directly from host memory. The resulting multiple program
transport streams are COFDM encoded, modulated, and transmitted with
upconversion.
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: Sun Solaris on SPARC, Sun Solaris x86 on Intel,
Linux, Windows NT/2000/2003/XP, and FreeBSD.

Driver Support
The VideoPropulsion Mux Drivers for the C1LP
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 C1LP 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.
