Analysis of Computer Hardware Affecting Video

When 60 de-interlaced fields per second digital uncompressed video is streamed to a computer, some video fields are lost and not able to be stored on a computer’s hard drive successfully. Additionally, this problem amplifies once multiple video sources are deployed. If it is possible to stream digital uncompressed video without dropped video fields, then a sophisticated computer analysis of the transmitted via IEEE 1394a connection video is possible. Such process is used in biomechanics when it is important to analyze athletes’ performance via streaming digital uncompressed video to a computer and then analyzing it. If a loss of video fields occurs, then a quality analysis of video is not possible. MOBILE COMPUTER HARDWARE The recording of video is complicated when mobility on a field is required. Seldom, desktop computers are used to collect video information out on a field due to the lack of mobility, weight and connectivity options. Laptop computers are utilized to perform the same functions with little or no impact on performance. However, the cost associated with powerful “desktop replacements” (laptops) often interferes with one’s ability to perform various tasks. Therefore it is important to understand whether certain computer hardware on a laptop computer improves the transmission of video via IEEE 1394a protocol or certain hardware configurations, often expensive ones, do not improve the transmission of video. This manuscript presents the examination of the following hardware components: 1) hard disk rotational speed (RPM), 2) amount of Random Access Memory (RAM), and 3) the number of video sources that record and transmit a video file.
