Rate-distortion optimization (RDO) is a method of improving video quality in video compression. The name refers to the optimization of the amount of distortion (loss of video quality) against the amount of data required to encode the video, the rate. While it is primarily used by video encoders, rate-distortion optimization can be used to ...
Video optimization refers to a set of technologies used by mobile service providers to improve consumer viewing experience by reducing video start times or re-buffering events. The process also aims to reduce the amount of network bandwidth consumed by video sessions.
Request and download all the files and resources, assembling them so that they can be presented to the user as a continuous flow video. The client software downloads first the index file through a URL and then the several media files available. The playback software assembles the sequence to allow continued display to the user.
Perceptual Evaluation of Video Quality (PEVQ) is an end-to-end (E2E) measurement algorithm to score the picture quality of a video presentation by means of a 5-point mean opinion score (MOS). It is, therefore, a video quality model. PEVQ was benchmarked by the Video Quality Experts Group (VQEG
Video converters are computer programs that can change the storage format of digital video. They may recompress the video to another format in a process called transcoding , or may simply change the container format without changing the video format.
Windows Media Video (WMV) is a series of video codecs and their corresponding video coding formats developed by Microsoft.It is part of the Windows Media framework. WMV consists of three distinct codecs: the original video compression technology, known as WMV, originally designed for Internet streaming applications as a competitor to RealVideo, and WMV Screen and WMV Image compression ...
This comparison contains download managers, and also file sharing applications that can be used as download managers (using the http, https and ftp-protocol). For pure file sharing applications see the Comparison of file sharing applications .
As performance is part of the specification of a program – a program that is unusably slow is not fit for purpose: a video game with 60 Hz (frames-per-second) is acceptable, but 6 frames-per-second is unacceptably choppy – performance is a consideration from the start, to ensure that the system is able to deliver sufficient performance, and ...
