Chapter 1 - Introduction

Introduction

This chapter outlines the key features of the Imperx HD-SDI

Express series of SDI frame grabbers.

VCE-HDEX02

VCE-HDEX03

VCE-HDPCIe01

Page 6 of 65

HD-SDI Express

The HD-SDI Express frame grabber series includes three models:

VCE-HDEX02 - an ExpressCard/34 card

VCE-HDEX03 - an ExpressCard/54 card

VCE-HDPCIe01 - a low-profile PCI Express x1 card

All cards include an SDI analog interface and a PCI Express x1 lane

interface. They provide the ability to capture digital video and audio data,

from an SD/HD SDI source, and transfer that data to host memory via a

PCI Express x1 interface. All of the cards share the same software ( i.e.

application program, libraries and driver ).

Functionality

•Supports an analog serial interface formatted per SMPTE 292M

with:

•SMPTE 274M framing providing 1080i ( 60 fields/sec ) or

1080p ( 30 frames/sec ).

•SMPTE 296M framing providing 720p ( 60 frames/sec ).

•Supports the 20 bit de-multiplexed HD format ( 4:2:2: YCrCb

where Y = 10 bits and C = 10 bits )

•Captures video data from an SDI analog interface, formats this

data and stores it into local FIFOs.

•Data can be formatted as 20 or 16 bit YCrCb 4:2:2 or as RGB-24

using a color space converter function.

•Supports two 48 KHz 24 bit embedded audio channels.

•Captures audio data from an SDI analog interface, formats this

data and stores it into local FIFOs.

•Audio data can be formatted as 24 or 16 bits per sample.

•Retrieves the formatted video and audio data from the FIFOs and

transfers it into host memory via a scatter/gather DMA over the x1

lane PCI Express interface.

•Provides the ability to upgrade the FPGA firmware in the field by

the user.

•HDPCIe01 only: Provides an SDI Loop-through capability.

A second BNC connector outputs a regenerated version of the SDI

signal received from the first connector.

•HDPCIe01 only: Provides an RS232/RS485 serial communications

COM port for the purpose of configuring an attached camera.

Interfaces SDI interface

The HD-SDI Express provides an HD-SDI compliant receiver interface

capable of acquiring SDI video/audio data at rates of 1.485 Gbps. The

receiver provides full SMPTE processing for signals compliant with

SMPTE 274M and 296M framing. The following formats are supported:

-1080p 30/25/24 fps

-1080i 60/50 fps

-720p 60/50/30/25/24 fps

-SD

SDI Loop-Through interface ( HDPCIe01 only )

The HD-SDI Express PCIe card provides an SDI output which is an

electrically regenerated and retimed version of the input SDI signal. This

is useful when the user requires that the frame grabber be in-line between

a video source ( i.e. camera ) and a video sink ( i.e. monitor ).

PCI Express interface

The HD-SDI Express PCIe card complies with the x1 low-profile PCI

Express add-in card dimensions as defined in the PCI Express Card

Electromechanical Specification revision 2.0.

The HD-SDI Express/54 and HD-SDI Express/34 cards comply with the

ExpressCard/54 and ExpressCard/34 package dimensions, respectively, as

defined in the ExpressCard Standard release 1.2. Both cards include a

37mm x 20mm extension area used to house the BNC connector.

The HD-SDI Express provides a x1 lane ‘end-point’ PCI Express interface

compliant with the PCI Express Release 1.2 specification. The design does

not support any memory mapped or I/O mapped peripherals on the card.

Access to the SDI Express’s FIFOs is achieved through DMA operations

that move the data from the FIFOs into host memory. The host cannot

directly access the contents of the FIFOs. The design supports host access

into PCI Express configuration registers as well as application specific

frame grabber registers.

The ExpressCard standard also defines a Universal Serial Bus ( USB ) and

a Serial Management Bus ( SMBus ) interface on the ExpressCard

connector. These interfaces are unused in the HD-SDI Express card

design.

Page 8 of 65

Serial COM interface ( HDPCIe01 only )

The HD-SDI Express PCIe card provides an RS232/RS485 bi-directional

Universal Asynchronous Receiver Transmitter ( UART ) for the purpose

of configuring an attached camera. The UART transmits and receives

ASYNC formatted characters with 1 Start bit, 8 data bits, no parity and

1 Stop bit. The baud rate of this interface can be configured by the user to

be any one of a set of standard bit rates ranging from 4800 to 115.2K bits

per second. The HD-SDI Express software exposes this interface as a

standard COM port to the host operating system.

Video Capture The video capture engine is responsible for receiving video pixel data and

qualifiers from the SDI receiver, formatting the data and transferring it

into on-board memory. The module receives 20 bits of video data

organized as 10 bits of Luma data and 10 bits of Chroma data as well as

VSYNC, HSYNC and DATA_EN strobes. The interface timing follows

the CEA861 model. The received video data is formatted as YCrCb 4:2:2.

The video capture module supports three modes of operation, as

configured by the user:

-YCrCb-20 mode – uses the 20 bit YCrCb 4:2:2 data received from the

SDI receiver.

-YCrCb-16 mode – uses the 20 bit YCrCb 4:2:2 data received from the

SDI receiver but truncates the 2 LSBs to form 16

bit data.

-RGB-24 mode – uses the 20 bit YCrCb 4:2:2 data received from

the SDI receiver, translates it to 30 bit YCrCb

4:4:4 data using a chroma resampler function, then

generates 30 bit RGB data using a color space

converter function and finally truncates the 2 LSBs

from each component to form 24 bit RGB data.

The video capture engine translates this data into doublewords ( 64 bits ),

as defined in Table 1 – Table 3. These tables reflect how the data will

appear in host memory.
