Like many other technical terms applicable to television technology, frame rate is also a term that cannot be easily understood by those who are not fully conversant with the subject. The frame rate is the measurement of frequency at which images are produced in a sequence. Obviously it is relevant only in the areas of film and video cameras, computer graphics and other motion capture systems. It is generally expressed as frames per second (fps). In high definition television 1080i and 1080p formats are the two modes of delivery of signals from the source to the television. The suffix I stands for interlaced and p stands for progressive scan. The progressive scan facilitates display at varied frequencies of 30 and 24 seconds.
The television generally has a frame rate of 30 frames per second. In the case of interlaced video it will displace half resolution per frame and in the progressive scan it will be almost double the rate. In progressive scan capture rate is equal to frame rate, while in interlace system the capture rate is double the frame rate because only one field is captured at each interval. The films will have a frame rate of 24 fps. Such a frame rate offers superb reproduction quality, provided the television is compatible with 24fps as well as with 1080p formats. This is the reason why consumers at times have to upgrade the television sets to make them compatible if needed.
24 frames per second progressive mode with NTSC television offers superb picture quality in the case of videos or film based on action themes. Images will be converted from 30 fps to the required 24 fps by the compatible high definition television to offer 1080p scan rate. The viewers can watch film reproduction without flickering or other blemishes. Sensing the consumer preference for the 24 fps progressive scanning, which offer highest standards of picture quality, all leading manufactures in the television segment like LG, Samsung, Sony, Philips and Panasonic have adopted the 24 fps with 1080p in their latest models. It is very much relevant where video signals are to be converted to the movie mode.
The 24 fps HDTV offers quality display as good as the one experienced in a theatre and hence its popularity among the consumers. The professional video makers also find the 24fps 1080p format more effective as it equals the movie standard as far as the resolutions, scanning process, aspect ratio and frame rates are concerned. The mode is easier or convenient for those who want to convert video into films. The consumers will be able to enjoy the benefits of real movie experience from the compatible HDTV with 1080/24fps mode.
