With the fast development of mobile technologies and wireless Internet access, video streaming share grows rapidly. New HEVC (High Efficiency Video Codec) standard was introduced by ITU-T in 2013. It increases compression rate and, in the same time, computational efforts. Thus development of efficient decoding systems for mobile platforms becomes actual problem. This paper is dedicated to analysis...
This paper proposes two unique optimization techniques over USB 2.0 scheduler for addressing low latency requirement of embedded systems. The first optimization technique proposes the new priority based scheduling algorithm of USB 2.0 scheduler for non-periodic data transfer. The second technique is a simple insertion algorithm for scheduling periodic data transfer in USB 2.0 scheduler. The capability...
High quality wireless audio transfer is essential for external digital audio products. There are two kinds of methods for transferring audio data. One is using proprietary RF channel and protocol for reliable audio transfer, the other is using preexisting 802.11 WiFi Network. Audio transfer via WiFi network is more general and preferred method compared to proprietary wireless transfer. But when WiFi...
When embedded devices are connected by USB bus, it is convenient to use Ethernet emulation model which can be used for conventional TCP/IP network. USB Communication Data Class (CDC) defines Ethernet over USB protocol which can be implemented by emulation protocol software, but when it is used with real system, it shows performance degradation problems especially for small size latency critical data...
Recent development of Smart TV shows rapid evolution in performance. Consumers may be reluctant to buy a television for fear of missing upcoming features. We have suggested innovative way for upgrading legacy TV, i.e. Set-Back-Box (SBB). SBB co-exists with previous TV connected over USB bus. SBB connected TV behaves as a cluster of 2 systems in a distributed computing environment. In this research,...
