Image capture
See freeze frame.

Image management
Stored image management denotes the ability to sort, arrange, and manipulate stored images into functional groups. Some systems allow the user to store images, but once done they cannot be arranged and are permanently stored in the order in which they were saved. This may be cumbersome.

Informatics
The application of computer science and information science to the management and processing of data, information, and knowledge. SEE ALSO Medical Informatics.

Information Infrastructure Task Force (IITF)
The Clinton Administration formed the IITF to articulate and implement a vision for the National Information Infrastructure (NII). The task force consists of high-level representatives of the Federal agencies that play a major role in the development and application of information and telecommunications technologies. Part of the IITF is the Health Information and Applications Working Group. The Federal organizations that are members of this group include: Department of Agriculture Department of Commerce (NIST and NTIA) Department of Defense (ARPA) Department of Education Department of Health and Human Services (NIH) Department of Veteran Affairs National Aeronautics and Space Administration (NASA) National Security Agency Office of Management and Budget

In-house Film Distribution Systems (IHFDS)
A film digitizer and/or "frame grabber," that captures and converts video images in a modality to a digital form, an image file server, display stations and communication capability.

Instructional Television Fixed Service (ITFS)
A non-broadcast television service that is typically used for closed-circuit instructional applications. It requires special antennas and converters to translate signals for viewing.

Integrated Advanced Information Management Systems (IAIMS)
Institution wide computer networks that link and relate library systems with individual and institutional databases and information files, within and external to the institution, for patient care, research, education and administration.

Integrated Services Digital Network (ISDN)
A digital telecommunications channel that allows for the integrated transmission of voice, video, and data; a protocol for high speed digital transmission. Simultaneous copper wire transmission of voice, images and data. No modem required for data. These networks consolidate voice and data facilities and provide a connection to a universal network, thus allowing the user to transmit any type of information, including full motion video to any other location on the network.

InterActive TeleVideo (IATV , ITV)
 

International Medical Informatics Association (IMIA)
 

International Organization for Standardization (ISO)
International Standardization Organization. Establishes and coordinates worldwide standards for electronic information exchange.

Internet Protocol (IP)
Packet transmission standard for the transmission of data, voice, video and other information over the Internet.

Interoperability
A state of complete compatibility among devices required to operate together with each other, with reference to a specified feature set or standard. This is an important consideration when mixing non-ITU-T codecs from different manufacturers and when mixing ITU-T codecs from different manufacturers which may support different capabilities. Remember that ITU-T codec systems revert to the highest common denominator for operation.

Inverse multiplexer (IMUX)
Re-aggregates split subchannels in a data stream into a single channel. See ISDN.

Isochronous
Used to describe the transmission of continuous media, implying finite size data samples generated at fixed intervals.

ITU-R (formerly CCIR)
An International Telecommunications Union (United Nations) international telecommunications standards-setting body, specializing in radio-spectrum usage.

ITU-T(formerly CCITT)
An International Telecommunications Union (United Nations) international telecommunications standards-setting body specializing in telecommunications.

ITU-T-Compatible Codec
A video codec which meets all the minimum requirements as set out in ITU-T Recommendations H.221, H.230, H.242, H.261 and H.320. In order to be compatible with the ITU-T Multipoint Control Unit (MCU), codecs also need to generate and receive commands as set out in H.231 and H.243. T.120 support is also desirable.
