The extended use of DMX512 protocol has been applied in many areas such as stage and theatre. While it has two inherent flaws in landscape lighting control: the quantitative limitation of control slots and slow bandwidth utilization ratio. This paper proposed the evolution of a management and control system for landscape lighting. By using the upper Internet management network, several lower DMX512...
Real-time video streaming over the Internet often suffers from a kind of congestion on the bottleneck links caused by the video stream itself, a phenomenon so called self congestion. The motion compensation based video coding algorithms make video streams of variable bit-rate nature, which cause burst traffic, extra transmission delay, and even queue overflow of the bottleneck link and video data...
This paper solved the problem of how to connect DALI (digital addressable lighting interface) with Internet. A design of embedded DALI dimming controller which based on muC -Linux embedded operation system is presented, the hardware construction using ARM7 MCU and the software conversion between thin TCP/IP and DALI protocol are mainly expounded. The DALI receiving/transmitting circuits and the information...
This paper introduced the improvement and trend of home network. After studying the CEBus standard and technology methods of embedded system's Internet accessing, an embedded gateway based on ARM for the home network was designed. In the design, using SoC chip designed for this project to connect CEBus and the home appliances at home helps users control them easily and remotely through the Internet.
The hardware and software method of developing EIB gateway based on ARM Linux is addressed after some summaries of the smart home development. Through establishment of serial communication by PEI16 handshake protocol, home Web server by boa, and primitive database to access, a remote Ethernet access to EIB device node test was established, which proved the utility of EIB ARM Linux server gateway....
