8/1995 to Present - Algorithm Engineering, Altamonte Springs, FL.

Title: Software Consultant / Owner

Independent contractor for the following customers:

Sony Playstation, Inc 2021

Provided consulting on prototype software for using the CX3 USB 3.0 Camera Controller.

Visible Light Digital, Inc 1/1999 - 1/2000

Ported Visible Light's MPEG OnStage Macromedia Xtra plugin to DirectShow and used DVD Navigator to provide DVD support for OnStage DVD product (www.OnStageDvd.com). More recently I created an OnStage DLL library to unify DVD and other multmedia support (MPEG, AVI, etc...) for OnStage products.

Recent development also includes ActiveX controls for HTML, VJ++, VC++, and VBasic development environments, and an ActiveX control specifically for PowerPoint support. All library and Active controls are developed with VC++. Sample applications development included Visual Base and Java.

FireTalk Communication Inc. 2/2000 - 10/2000

Telecommunications software development for integrating the Firetalk voice over the web application with the physical telephone network. I developed the Firetalk Phone server on an MS NT platform, using VC++ for program code and Natural Microsystems ISDN hardware. The server could accept or place calls and route normal telephone traffic to the Internet for conferencing with Firetalk users. An IVR (Interactive Voice Response) system was developed to handle login, voice messsaging, and connections. Access databases and Microsoft's database API were used to programatically control user authentication, directory services, and dialing restrictions. In a subsequent project I developed the Firephone Conference server.

Whereas the Firetalk Phone server allowed PSTN (Public Switched Telephone Network) calls to be integrated into Firetalk conferences, the conference server allowed PSTN conferencing to be controlled by the Firetalk application. This allowed you to create and participate in PSTN conferences from any location where access to the Internet was available.

ECC International, Inc - 7/1998 - 1/2000

Consulting on the development of an Engagement Skills Trainer that provides small arms training. This is a system that presents 3D graphics and video on a projection screen and uses actual weapons modified to project a laser on the screen for aiming. The software is developed with Visual C++ and MFC. My responsibilities included development of all code related to the video based scenarios. This includes run-time and scenario editing and creation tools. In addition to general MFC programming I utilized the Direct X and DirectShow API's for controlling the video and rendering graphic overlays. The scenario editing tool allow a scenario developer to specify video segments and links, assign branching based on various events such as shooting a target or instructor input, and creates the run-time database. A hit plate editor tool was developed to allow the developer to draw graphical hit plates over the video using geometric objects rather than pixels. The hit plate editor provides a means to specify key frames and automatically interpolate intermediate frames to reduce the level of effort in hit plate creation.

In addition I developed a VxD driver and C++ class for the laser-tracking device. I also assisted in other areas by providing a general architecture and base code for the real-time portion of the application, and a socket based networking class for communicating with the Instructor/Operation Station.

10/1993 – 8/1995 FutureTel, Inc., Sunnyvale, CA.

Title: Director of Software Engineering

( Previously Intelligent Instruments Corp. See next history )

After FutureTel, Inc acquired Intelligent Instruments assets and employees in October 1993, I continued to manage the Florida office and maintained a staff of six software engineers including myself. The File Server development effort in California had been canceled in favor of a ISA bus real-time MPEG encoder. The Florida Group was retasked to replace the Server hardware and proprietary terminal with a PC network and MS Windows based terminals. This proof of concept design was demonstrated in May 1994.

Software development was shifted to reuse of file server components for delivery of MPEG video over T1 communications lines, and driver and applications support for the MPEG encoder. The Florida Group produced the following products in which I performed in both the capacities of software designer and manager.

· MPEGthere and MPEGanyware products. These products distribute live MPEG encoded videos over ethernet and T1 networks. The initial system was deployed by KRON TV for distribution of BayTV programming to cable headends in the San Francisco area. MPEGanyware allows one or more encoders to multicast video over ethernet, with an unlimited number of redirectors which can retransmit over T1 lines. MPEGthere is a smaller scale single unit which encodes and transmit MPEG over T1/ISDN lines. These products incorporate a unique technique, developed by the Florida Group, which performs rate matching for synchronous transmission by decomposing the MPEG system stream and padding per ISO 11172 specifications.

encoder. The PrimeView driver operated at interrupt level, ensuring reliable encoding in the Windows environment. The installable driver provided both a C API and an MCI interface. Included with the driver was a VCR like application and installation program.

files at the GOP (Group Of Pictures) boundary. This application allowed the user to create an EDL ( Edit Decision List ) of mark in/out points using an MPEG decoder for visual editing.

VCR and MPEG decoder and encoder operation to allow frame accurate production of MPEG content from video tape. This application allowed the user to create an EDL ( Edit Decision List ) of mark in/out points using a VCR for selection of source material. A unique feature of MPEGworks was the ability to view the decoded MPEG material while encoding. Since most decoders provide only an MCI programming interface, we developed a Virtual File System based on our file server technology which allowed non-file based data to appear as part of the MS-DOS file system. MPEGworks 2 was a recent rewrite which allowed the spin-off of a product called MPEGworks Engine and provided a enhanced user interface completely rewritten using C++ and Microsoft Foundation Class.

control of the decoder, encoder, and VCR from the application program. The engine provides a C programming interface with an event driven programming model. Also provided with the engine was a VBX control for interfacing to Visual Basic.

allow capable decoders to select and view a live stream transmitted from an MPEGanywhere system.

programming for MPEG transmission applications to third parties. One major project multiplexed ten 2.1Mb MPEG streams into a single 21Mb MPEG stream and retransmitted through the customers proprietary hardware design. This design incorporated multiple ethernet networks and low-level programming to a DMA interface on the customers prototype hardware.

5/92 – 10/93 Intelligent Instruments Corp, Sunnyvale, CA.

Title: Director of Software Engineering

Operating as a subsidiary, IIC of Florida, Inc, I managed a group of five software designers in an effort to build a Multimedia File Server capable of serving up to 80 simultaneous clients over primary rate ISDN lines. Our responsibility was to develop the host level software operating on a Sun computer system and the embedded graphics and windowing software for a proprietary terminal. We worked in cooperation with Intelligent Instruments Corp.'s California division, who's responsibility was a large scale development of a proprietary hardware and embedded software system to move multimedia data between storage devices and the ISDN communications interface

The CA division also produced a set of ISA bus boards which performed H.261 video compression, audio capture, and ISDN/T1 interfacing. IIC of Fla supplied the majority of applications and driver software for these boards.

· System design and management of software development for a Multimedia File Server based on Sun host computer and IIC developed custom data routing hardware. Development highlights of the file server include:

· Object-oriented Multimedia Scripting Language (MSL).

· Network independent distribution of resources with high-performance message passing architecture.
