Cost-optimal Data Retrieval for Video Servers with Variable Bit Rate Video Streams
نویسندگان
چکیده
We consider the problem of data retrieval from disk storage in a video server where the data is stored in constant size blocks. The two critical resources of a video server are the amount of disk I/O bandwidth and the main memory buffer required to support a video stream. We propose a new algorithm that allows us to determine the cost-optimal trade-off between these two server resources as well as bounds and statistics of the start-up latency seen by the user.

A Full-Fuzzy Rate Controller for Variable Bit Rate Video
In this paper, we propose a new full-fuzzy video ratecontrol algorithm (RCA) for variable bit rate (VBR) videoapplications. The proposed RCA provides high qualitycompressed video with a low degree computational complexity.By controlling the quantization parameter (QP) on a picturebasis, it produces VBR video bit streams. The proposed RCAhas been implemented on the JM H.264/AVC video codec andth...
متن کاملDeterministic Admission Control Strategies in Video Servers with Variable Bit Rate Streams
Video servers are a key component in multimedia systems. Due to the real-time requirements and high resource demand of digital media, a video server must restrict the number of simultaneously serviced media streams. We consider the admission control problem in video servers for the retrieval of media data from secondary storage. Admission control decides whether or not a new request can be acce...
متن کاملConstant Data Length Retrieval for Video Servers with Variable Bit Rate Streams
Video servers store digitized, compressed continuous media information on high-capacity secondary or tertiary storage [6]. The secondary storage devices allow random accessible and provide short seek times compared to tertiary storage. Video server design differs significantly from that of traditional data storage servers due to the large size of the objects stored and the real-time requirement...
متن کاملVideo-server retrieval scheduling and resource reservation for variable bit rate scalable video
State of the art digital video compression produces bursty, variable bit rate video. The bursty nature of compressed video raises challenges in the design of video servers. In this paper, we first present a method for the efficient retrieval of bursty video data from the disk system to the memory of a digital video server. For a single video stream, the proposed retrieval schedule minimizes the...
متن کاملStatistical Admission Control in Video Servers with Variable Bit-Rate Streams and Constant Time Length Retrieva
We consider the admission control problem in video servers for the retrieval of media data from disk storage. We assume that the I/O bandwidth of the server disk is limited. Given a certain I/O bandwidth, admission control decides whether or not a new client can be accepted without affecting the quality of service promised to the already admitted clients. Assuming variable bit rate (VBR) video ...
