Digital video recording expert witness candidates typically have an advanced degree, and a background in electrical engineering, computer engineering, or computer science. Experts in digital video recording may have an affiliation with a technical industry organization such as the IEEE. Experience in forensic analysis (for example – audio forensics, computer forensics or digital forensics), can be important for a case. Digital video recording devices encompass set-top boxes, portable media players, and digital camcorders.

A digital video recording expert witness could provide expertise in intellectual property matters such as a patent litigation or a trade secret dispute. An expert in digital video technology might also assist law enforcement with an analysis of video evidence. Litigation support by a digital video recording expert witness could include device examination, a forensic investigation, expert report preparation, deposition testimony, and courtroom testimony. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a technologist with prior expert witness testimony experience. Lead counsel may also seek a digital video recording subject matter expert for pre-litigation consultant work.

Expert Witness #255869

This expert holds a B. A. in Mathematics and Computer Science. This expert joined an early provider of timesharing computer services, where this expert developed mathematical and communications software. This expert performed hardware design, installation, and testing of optical character recognition equipment. This expert wrote a bit-slice processor microcode for the first broadcast video framestore/synchronizer and has taught electronics to art students.

This expert founded a company to design and build digital television processing equipment. This equipment converted the field-sequential color television signal from the Space Shuttle to NTSC, for viewing, recording, and distribution to television networks. The conversion and NTSC encoding were accomplished digitally. This company also undertook contracts for the design and development of special-purpose digital television equipment for a number of clients. All of these projects made extensive use of digital video; most dealt with the integration of television systems and computer systems.

This expert introduced video, high-definition television (HDTV), and accurate color technology to computer workstations and developed the system architecture for a product that brings video into the workstation environment.

This expert has been an active member of the Society of Motion Picture and Television Engineers (SMPTE) Working Group on Studio Video Standards, and its various subgroups, and has contributed to many video standards, including ITU-R Recommendations BT.601 and BT.709. This expert was a major technical contributor to the ANSI/SMPTE 240M and 260M standards for 1125/60 HDTV. This expert was involved in SMPTE's Working Group on Digital Pictures, which developed the SMPTE 168M (DPX) standard for the exchange of digital film frames in the film production community. This expert advocated the square-pixel common image format for HDTV, and was the prime mover to have this proposal accepted unanimously.

This expert worked for many years within television and computing standards organizations to encourage the adoption of standards for the use of television technology in computer environments. This expert worked to encourage the computer industry to adopt the ITU-R BT.709 HDTV colorimetry standard for accurate color interchange. This effort resulted in provision for ITU-R BT.709 colorimetry in the TIFF 6.0 file format, and led to the BT.709 color parameters being adopted in the sRGB standard for desktop computing.
