One of three types of digital pictures in an MPEG data stream. An I-picture is not predictive and is essentially a snapshot picture. This type of picture generally has the most data of any of the picture types. A picture coded using information only from itself. For that reason, an I-picture can be decoded separately.
Industry:Software
The IRE standard oscilloscope frequency response characteristic for measurement of level. This characteristic is such that at 2 MHz the response is approximately 3.5 dB below that in the flat (low frequency) portion of the spectrum, and cuts off slowly.
Industry:Software
An oscilloscope scale in keeping with IRE Standard 50, IRE 23.S1, and the recommendations of the Joint Committee of TV Broadcasters and Manufacturers for Coordination of Video Levels.

a) A linear scale for measuring the relative amplitudes of the various components of a television signal. Reference white is assigned a value of 100, blanking a value of 0. b) The values for NTSC composite and for SMPTE 240M are shown in the following table. One IRE unit corresponds to 7-1/7 mV in CCIR System M/NTSC and to 7.0 mV in all other systems. Measurement procedure developed by the Institute of Radio Engineers, the predecessor to the IEEE.

One of the advantages of an ISA transfer is that it allows the user to process images as they go through the processor. However, its utility is limited by its low bandwidth, Even under ideal conditions, the ISA transfer requires three to five BCLK cycles at 8 MHz to transfer a single pixel. This represents a severe system throughput penalty; a large percentage of the available (and already limited) bandwidth is consumed by the transfer.
