Phoenix Children’s Hospital Utilizes Streaming Encoders to Broadcast and Record Live Surgical Events for Training, Evaluation and Conferences

As one of the largest children’s hospitals in the country, Phoenix Children’s Hospital (PCH) provides world-class inpatient, outpatient, trauma, emergency and urgent care to children and families throughout the Southwest. As a teaching hospital, PCH also provides training programs and conferences for medical students, residents and fellows. As part of the program, all surgical suites are equipped with a proprietary video management system that enables live viewing and recording of all surgical events.

Application Requirements

Video quality and the sheer expense of broadcasting-capable systems are two of the most pressing issues. “Enabling proprietary system to be IP aware has been prohibitively expensive,” says John Vaux, Enterprise Infrastructure Architect, Information Technology Services with Phoenix Children’s Hospital. “Currently the only method for getting video out of the system is through analog composite video cables and a teleconferencing codec. Unsurprisingly, this (method) downgrades considerably the video quality of the HD surgical equipment.”
As a result, PCH looked to find a streaming encoder to meet all of their needs. In addition to the issue of cost, the solution needed to encode DVI-D signals and adhere to a small form factor for further flexibility and space constrains. For PCH, encoding flexibility is a necessary consideration to allow them to take full advantage of the diverse video formats available to them. Whereas HDMI carries television standard resolutions and refresh timings, only DVI-D can offer the increased flexibility to encode from a computer video card source. Secondly, the encoder solution would need to compete for space in an environment where, typically, the video switch, rack mounting equipment, power and networking are housed.

The Solution

While evaluating a variety of solutions, PCH came across the AVerCaster HD Duet Plus F239+, a multicasting streaming encoder from AVerMedia Technologies, Inc. “The AVerCaster HD Duet Plus F239+ proved to be the perfect solution that met all of the requirements we were looking for,” John commented. “Using DVI-D to HDMI cables into the AVerCaster HD Duet Plus F239+, we were then able to encode our video as an IP stream and send the video anywhere, which enabled us to provide full, high definition video streams of live surgical procedures for an interactive surgical conference, which was held in a separate building within our campus. The quality of video and ease of use was a hit with our surgeons, AV team, and conference organizers.”

Streaming Encoder for Medical Training

The AVerCaster synchronized the video signal delivered from the switch. In contrast, several other solutions tested simply refused to lock onto the video signal while switching resolutions. The AVerCaster HD Duet Plus F239+ maintained the signal lock perfectly.
On the issue of space-saving, the AVerCaster HD Duet Plus F239+ fulfilled the form factor requirements by PCH. Small, compact and versatile, the AVerCaster HD Duet Plus F239+ was a perfect fit.


“The best thing about the AVerCaster HD Duet Plus F239+ and AVerMedia is that not only did the product do what I needed it to do, but when I required support, AVerMedia worked with me to see me through the difficulty,” concluded John. “The final remaining piece included a custom firmware. The firmware allowed the AVerMedia device to talk to our Milestone Video Management System which enabled seamless integration throughout the environment.”
