FD300™ Forward Video Processing Board

FD300 Video/Audio Processing Card

General Purpose Video Inputs, Processing, Output BoardDesigned for Broadcast Automation Environment

FD300™

Highest level of reliability

for low-budget are based on: Unique hardware Optimized software Many years of SDK usage for

different broadcasting tasks solving

Uniqueness of Hardware

FD300 provides Simultaneous ingest of up to 2 channels of video with frame

synchronization and switching of sources Simultaneous record and playback of video and audio (up

to 6 audio mono-channels) Pass-through one of several sources of video and an audio-

signals (software switching) with an adjustable audio delay Exact synchronization of video and audio Mix of two streams of video data with simultaneous titling Support of all analog video signals Synchronization of a video output to any external source

(genlock) Generation of a signal of a mask ("chroma key") for input

channels Additional video output of the alpha - channel for mixing on

an external mixer options for digital video signals as SDI and ASI

Part B. Forward SDK

Forward SDK have two groups 1. Microsoft Standard API : VfW, and Direct Show Filters, Audio Wave device

2. Darim-Softlab COM-based APILow-Level API : (HD as well as SD resolution available)

hardware management & control (Direct Forward Control)Capture and playback different data trough video buffers ( Memory Buffer Access)

High-Level API : Easy to use, mostly File Operation

Playback different type filesForward OnAir application management ( Forward OnAir application Use Only High-level API)

Forward SDK Functional structure Microsoft API

I. VfW (Video for Windows) II. Audio Wave Device ( Audio Capture and Playback)III. DirectShow filters

Darim API1. Capture SDK : ( Only Low-level )2. Video Playback SDK ( High-level )3. Titling SDK ( Both Low and High-level)4. Darim OnAir application command’s SDK ( Only

High-level)5. Board configuration SDK ( High-level )6. Other SDK (only Low-level) : many other

miscellaneous features like Low-level playback

Microsoft API (I,II) Darim VfW™ (Video for Windows)

capture driver allow you to capture video through Microsoft standard API

Darim WAVE device (following Microsoft standard system audio driver) allow you to capture and playback up to 6 mono channel by Microsoft standard API

Microsoft API (III-1) Darim DirectShow™ source filter

allow you capture up to 2 uncompressed video streams + up to 6 mono audio streams from FD300 board

Darim DirectShow™ render filter allow you playback one uncompressed video stream + one stereo/mono audio stream on FD300 board

Microsoft API (III-2) Darim DirectShow™ ASI source

filter allow you capture MPEG2 transport stream from ASI input (by FD210 board)

Darim DirectShow™ ASI render filter allow you playback MPEG2 transport stream by ASI output (optional ASI daughter board required)

1,2 32 Inputs Capture1 Output CaptureWhile multichannel Play

Darim API : 1. Capture SDK

This Low-level capture SDK allows you capture videos and audios through Memory buffer from : Forward board Input Stream

up to 2 video streams alpha stream(Key/Mask) up to 6 mono audio streams

Forward board output stream One Video Stream 6 mono audio streams

Darim API : 2.Video Playback SDK This High-level SDK allows you playback video and/or audio

tasks: AVI-files with any VfW codec (VfW codec should be installed on your

PC) MPEG Movie Picture (JPG, TGA, PNG, BMP) LIVE video channel (one from 6 user selected inputs of Forward300)

Tasks will be played one by one exactly at specified time with frame accuracy

During one task playback you can prepare next task (check file, load beginning part of the file) and then start playback of the prepared task with cross-fading

At the same time, additional audio players ( unlimited number of players) allow you to playback Audio files. For example:

One long audio file playback together with image sequence playback ( slide show )

Additional audio stream playback (Matrox movie have splitted video and audio as AVI–file and WAV-files)

Darim API : 3.Title SDK (I) This SDK includes both High-level and Low-level API:

Low-level Titling API allows you to playback generated title images (RGBA) trough video buffer

High-level Titling API allows you playback files (TGA,BMP,PNG,JPG, AVI with/without Alpha channel, Flash,Image Sequences, Movie Sequences,Clock-Darim Format,etc) by title project(should be created by FDTitleDesigner)

You can use both API at the same time into your application.

Darim Title SDK contains Darim Title Engine which can mix unlimited number of layers. Every layer have a title region( own user defined rectangle region) And a corresponding FIFO ( PC Memory buffer for RGBA images)

Darim API : 3.Title SDK (III)

Darim Tiltle SDK includes 3 engines which generate 3 streams for DSP Mixer on Forward300 board: Title, Background and Foreground

One title engine can mix unlimited number of regions at the same time

Your application can use both Low-level and hi-level API without any limitation

4 input Forward Mixer

Darim API : 3.Title SDK (IV) How to use Low-level Title API Memory(Video, RBGA) buffer (FIFO) used for

guaranty of title playback without any drops Your application should generate images one

by one and put it into FIFO – title engine will take away images, mix all and show result

You can start/stop and hide/show any title region with frame accuracy – just specify time( frame number) when command should be executed.

Low-level Title API can be applied to make HD title application as well as SD.

Multi-Layer Title Designer

Title ObjectIs Group of Title Elements, Each element has one region

Title ProjectIs a set of all Title objects

Darim API : 3.Title SDK (V) How to use High-level Title API You can :

Open a title project (should be created before by FDTilteDesigner)

Specify a task file ( Flash file, AVI, Image..etc) for every title object of selected title project

Start playback at specified time Obtain rest time and current state Stop or abort current playback (by next start title

object continue playback from stopped position) At the same time you can load unlimited

number of title projects (all created/loaded title regions have to has different Z-order)

Darim API : 4. Darim OnAir application command’s SDK SDK for Programming remote client

control S/W for FDOnAir Server system. You can send any command ( which

operator can do by mouse click ) into running FDOnAir application

(EX. You can generate schedule for playback by your own application – as a result, FDOnAir application will be playback server and your application will be client application)

Darim API : 5. Board configuration SDK

You can call FD300 configuration dialogs from your application, then save and restore settings

Forward control: Low-level playback of uncompressed video FD300 internal 4-input mixer management FD300 internal audio mixer management FD300 input video switcher management Others like Security control, board selection, board

information scan, etc. which is not so important but we have many others as well( Contact us )
