59.94p is the frame rate used for 720p broadcast HDTV in the USA and other countries with an NTSC broadcasting history, as specified in SMPTE 296M. The exact rate is 60000/1001, which works out to be slightly over 59.94 frames per second. 60p is a progressive format that is very close to the 60000/1001 broadcast system used in some countries.
In the United States, the original ATSC standards for HDTV supported 1080p video, but only at the frame rates of 23.976, 24, 25, 29.97 and 30 frames per second (colloquially known as 1080p24, 1080p25 and 1080p30).
For the commercial naming of a product, the frame rate is often dropped and is implied from context (e.g., a 1080i television set). A frame rate can also be specified without a resolution. For example, 24p means 24 progressive scan frames per second, and 50i means 25 interlaced frames per second. [51] There is no single standard for HDTV color ...
The frame rate of 1080i is usually 50 or 60 Hz. It depends on the region. In areas using the PAL or SECAM standards, like Europe and parts of Asia, the frame rate is 50 Hz. In regions using NTSC, like North America and Japan, the frame rate is 60 Hz. The frame rate refers to how often a new field is shown per second.

Often, the rate is inferred from the context, usually assumed to be either 50 Hz (Europe) or 60 Hz (USA), except for 1080p, which denotes 1080p24, 1080p25, and 1080p30, but also 1080p50 and 1080p60. A frame or field rate can also be specified without a resolution. For example, 24p means 24 progressive scan frames per second and 50i means 25 ...
