Streaming Endoscopy

 

One way to Live Stream Endoscopy

Although it will not be in HD, use Skype to stream your endoscopy in teaching and education setting.

ASYNCHRONOUS Transmissions

1)

Use a Windows based PC or Laptop with the latest version of Skype installed

2)

Use a good quality headset with microphone

Most PC’s have audio out and microphone in connections – this makes it possible to use a cabled headset with microphone. Older Laptop’s have similar connections but some newer Laptop’s use the built in microphone and only provides audio out. It is not recommendable to use the built in microphone, but it is feasible in the asynchronous setting since you are close to the Laptop during transmission.

3)

Install ManyCam from http://www.manycam.com/

ManyCam offers a lot of options. Comes in a free version and you can buy a pro version for $49.95. ManyCam simulates a video out source and direct this source to Skype. In Skype video settings you can choose to broadcast the ManyCam video source through Skype. The ManyCam source can be a stored video, some still images etc.

SYNCHRONOUS (LIVE) Transmissions

1)

Use a Windows based PC or Laptop with the latest version of Skype installed

2)

Use a good quality headset with microphone (USB/Wireless type). For synchronous transmissions you need a wireless type of headset (fx. USB Wireless type from Logitech, model H800. This headset is plug-and-play, very easy to set up and works with Skype. It comes with a USB dongle so you do not have to struggle with Bluetooth).

3)

Direct a video source to Skype

Video from the endoscope

Video from the fluoroscopy system

Video from a room camera

The PC or Laptop has to be equipped with a hardware based video grabber (video in from the external source). This video grabbers “video out” has to act as a source that Skype can broadcast. There are some hardware systems available – one is the USB-Live2 from www.hauppauge.com/site/products/data_usblive2.html

USB-Live2 cost $49.00. It is a USB video capture device, for recording or streaming video. It can stream video to Skype, Adobe Flash Encoder or Xsplit. USB-Live2 attaches to Windows based laptop and desktop PCs for recording and streaming.

Specifications:

Video digitizer: 720×480 for NTSC, 720×576 for PAL video sources

Video source: S-Video or composite video

Audio input: left and right stereo audio

50cm USB cable

Video capture format using WinTV v7: MPEG-2

Image capture format using WinTV v7: JPEG, BMP

System requirements:

PC with 2.8 GHz single-core or multi-core 1.8GHz

Microsoft® Windows® 7, Windows Vista or Windows XP (min. service pack 2)

USB 2.0 port CD-ROM drive for software installation

OBS! There might be a problem with the external video source (endoscopy rack, fluoroscopy, room camera). Most room cameras have S-video out or composite video out – so it should be compatible. The video source from the endoscopy system often is an YC source and this can create some problems and you have to convert the YC to analog signal (see  “FC-10D Composite YC Comb Filter & Transcoder” from Comprehensive/Kramer).

4)

In Skype video settings – choose the USB-Live2 as source
