All attempts at using this format for terrestrial TV transmission were abandoned by the mid-1990s. Attempts at implementing HighVision as a 6 MHz broadcast channel were mostly unsuccessful. HighVision video is still usable for HDTV video interchange, but there is almost no modern equipment available to perform this function. The NHK system was standardized in the United States as Society of Motion Picture and Television Engineers (SMPTE) standard #240M in the early 1990s, but abandoned later on when it was replaced by a DVB analog standard. The Sony HDVS system was presented at an international meeting of television engineers in Algiers, April 1981 and Japan's NHK presented its analog high-definition television (HDTV) system at a Swiss conference in 1983. Modern HD specifications date to the early 1980s, when Japanese engineers developed the HighVision 1,125-line interlaced TV standard (also called MUSE) that ran at 60 frames per second. The 720p format is still HD quality and is preferable for editing and playback on a computer.Further information: Analog high-definition television system If your videos are recorded in 1080i or 1080p, consider down-converting them to 720p.We recommend to use PlayMemories Home™ software since it can play videos of up to 4K quality.
Increasing the RAM of the computer may help eliminate these issues, but isn't guaranteed. This will release some of the RAM or system memory used and shared by running multiple applications. Close other applications running in the background.SolutionĬheck the following information to improve HD video playback on your computer. Although some computers support 1080i and 1080p, these formats are best-suited for HDTV. While playing HD videos, especially 1080i or 1080p, image noise and dropped frames may occur because they task the computer processor. Videos recorded in High-definition (HD), like AVCHD, XAVC, XAVC S HD, or XAVC S 4K, may play choppy when played on a computer.
