In [1] we introduced a new real-time variable frame rate control scheme. It is based on the video jerkiness and it can be applied to both coding and transcoding. This scheme constantly traces the motion of the incoming video and automatically tunes the outgoing frame rate according to the level of jerkiness acceptable by the user.
This scheme has been conceived in the framework of mobile communications, which calls for an optimum use of both the available bandwidth and terminal resources.
In this paper we present a subjective assessment of our solution carried out in a professional laboratory suitably equipped. Towards this aim a group of non-expert users was asked to express their preference when watching side by side the same video coded at variable frame rate and at fixed frame rate. Results show that most of the times a variable frame rate control based on a dynamic bit/frame allocation scheme may substantially improve the video quality perceived by the users.
在[1]中,我们介绍了一种新的实时可变帧率控制方案。它基于视频混响,可以同时应用于编码和转码。该方案不断跟踪传入视频的运动,并根据用户可接受的跳动程度自动调整传出帧速率。 P>
该方案是在移动通信框架中构思的,该框架要求同时充分利用可用带宽和终端资源。 P>
在本文中,我们对在配备适当的专业实验室中进行的解决方案进行了主观评估。为了实现这一目标,要求一群非专业用户在并排观看以可变帧频和固定帧频编码的同一视频时,表达他们的偏爱。结果表明,在大多数情况下,基于动态位/帧分配方案的可变帧率控制可以显着改善用户感知的视频质量。 P>
