PCRTT Enhancement for Off-Line Video Smoothing
نویسندگان
چکیده
A n enhancement of the Piecewise Constant Rate Transmission and Transport (PCRTT) algorithm for reducing the burstiness of a video stream based on smoothing constant intervals is proposed. The new algorithm, called e-PCRTT, relies on geometrical considerations rather than traditional rate-control analysis. E-PCRTT is shown to construct transmission rate-plans with smaller buffer sizes, as compared to the original PCRTT, and alternatively, for the same buffer size, e-PCRTT reduces the number of bandwidth changes compared to PCRTT. In addition, e-PCRTT produces a rate-plan that requires a smaller initial playback delay.

Efficient Changes and Variability Bandwidth Allocation for VBR Media Streams
Recently the Internet bandwidth is rapidly increased. Current available network traffic includes not only text but also graphics, such as JPG, GIE Many multimedia applications are emerging, such as Video on Demand (VoD) and distance learning. These services involve complicated network connections between servers and clients. To simplijj this system, we propose an effective and efficient traffic...
متن کاملA dynamic programming methodology for managing prerecorded VBR sources in packet-switched networks
Broadband networks will increasing carry prerecorded traac, such as high-delity audio, short multimedia clips, and full-length movies. We study how to manage the transmission and transport of traac from prerecorded VBR sources so that network resources are ee-ciently utilized and end users receive satisfactory service. Speciically, we study Piecewise Constant-Rate Transmission and Transport (PC...
متن کاملOptimal Video Stream Multiplexing through Linear Programming
This paper presents a new optimal multiplexing scheme for compressed video streams based on their individual ePCRTT transmission schedules. A linear programming algorithm is proffered, which takes into account the different constraints of each client. The algorithm simultaneously finds the optimum total multiplexed and individual stream schedules that minimize the peak transmission rate. Since ...
متن کاملMeshFlow: Minimum Latency Online Video Stabilization
Many existing video stabilization methods often stabilize videos off-line, i.e. as a postprocessing tool of pre-recorded videos. Some methods can stabilize videos online, but either require additional hardware sensors (e.g., gyroscope) or adopt a single parametric motion model (e.g., affine, homography) which is problematic to represent spatiallyvariant motions. In this paper, we propose a tech...
متن کاملDynamic Programming Based Smoothing of VBR Video Traffic
The compression of videos using variable-bit-rate encoding produces constant quality video at the expense of significant bit-rate variability. Intelligent traffic smoothing techniques are needed to support efficient network resource utilization. In this paper, we examine a class of bandwidth smoothing algorithms and propose a novel enhancement that uses dynamic programming (DP) to improve upon ...
