Mask processing is commonly used in many video/image processing functions such as scaling, noise reduction, and edge enhancement by referring several pixels in the adjacent area to generate a processed pixel. Embedded memory therefore occupies large area and consumes power to store and process pixel data, especially for those low-cost applications without a framebuffer. In this paper, we design a...
Designing a real-time video-streaming system involves the challenges of, network congestion and bandwidth fluctuations, lowering the video quality. In this paper, a realtime video-streaming system is designed and implemented for scalable video coding (SVC) with an adaptive control scheme, containing macro- and micro-control, to resolve the bandwidth fluctuation and network congestion. Under macro-control,...
Delivering multimedia streaming on Internet remains several limitations, such as bandwidth fluctuations and network conjunction. We present a multimedia gateway design including dynamic bandwidth estimation, SVC extractor and buffer management to resolve the limitations. The dynamic bandwidth estimation not only selects the appropriate SVC sub-stream, but also measures the change of bandwidth and...
This paper proposes a remote thin client system for real time multimedia streaming over VNC. A remote frame can be split as two parts, i.e. high motion part and low motion part, and transmitted through the Internet from servers to clients according to the proposed hybrid RTP protocol. A Dynamic Image Detection Scheme (DIDS) is proposed to automatically detecting the high motion part of a frame with...
With the growing of Internet service and users, multimedia video streaming application becomes more popular. There are two limitations: limited bandwidth affects high quality video delivery and high bit error ratio reduces system throughput. A packet with bit error is dropped in transport layer. H.264/AVC support high coding efficiency and network friendly. UDP-Lite is an idea that by pass packet...
With the growing of internet service, multimedia applications require higher communication speed. The network traffic has rapidly increased that produces amount of interrupts, memory copies and checksum calculation in end system. The CPU workload is heavy and the processing of network protocol task is the bottleneck. In this paper, we propose a UDP/IP ASIC to accelerate networking multimedia transmission...
Derived from the thought of data cube, this paper presents a new database structure model which organizes multimedia data in a multi-dimensional data cube and presents a new theory for storing non-structure data named matrix division method. With the new theory to organize and store multimedia data, clustered data are stored in instance table. A leading data corresponding are stored in dimension table...
