Management of IEEE 802.11e Wireless LAN for Realtime QoS-Guaranteed Teleconference Service with Differentiated H.264 Video Transmission
Various realtime multimedia applications will be provided in next generation Internet where IEEE 802.11e wireless LAN will be widely used as broadband access networks. The characteristics of the wireless channels in IEEE 802.11 (i.e., fluctuating bandwidth and large error rate), however, impose challenging problems in the efficient QoS-guaranteed realtime multimedia communications with strict Q...
متن کاملHardware architecture design for variable block size motion estimation in MPEG-4 AVC/JVT/ITU-T H.264
Variable block size motion estimation is adopted in the new video coding standard, MPEG-4 AVCIIVTIITU-T H.264, due to its superior performance compared to the advanced prediction mode in MPEG-4 and H.263+. In this paper, we modified the reference software in a hardware-friendly way. Our main idea is to convert the sequential processing of each 8x8 sub-partition of a macroblock into parallel pro...
متن کاملPerformance Comparison of Auxiliary Vector and RAKE-MF Receiver for Transport of H.264/AVC Video Over DS-CDMA Wireless Channels
In this paper, we propose a robust transmission technique for packet-based H.264/AVC video transmission over DS-CDMA wireless channels using Auxiliary Vector (AV) and RAKE-MF receivers and confirm the superiority of the AV receiver. AV Filtering is an iterative algorithm that has fast convergence for short data records. In the proposed system, the H.264 video data packets are packetized and tra...
متن کاملRealtime H.264 Encoding System Using Fast Motion Estimation and Mode Decision
H.264 provides various useful features such as improved coding efficiency and error robustness. These features enable mobile device to adopt H.264/AVC standard to achieve effective video communications. However, the encoder complexity is greatly increased mainly due to motion estimation (ME) and mode decision. We implemented a realtime H.264 encoding system based on DSP and FPGA chip using the ...
متن کاملA Framework for Interactive Realtime Image Editing
We present a complete framework for interactive image editing with a focus on quickly obtaining results based on user input via brushstrokes. The goal is to show feedback to changing input in realtime while maintaining high quality output. We achieve this by extracting vital information in the form of local color clusters and a corresponding locally linear structure from the input image. With t...
