This paper based on embedded technology, video coding compression technology, GPRS mobile communications technology and so on. Design a video monitoring system of embedded wireless remote mobile. The front end hardware platform choose S3C2440 chip of SAMSUNG company as MCU.GPRS wireless module to send data. The software platform choose embedded Linux operating system. Construct the module of video...
Nowadays multimedia teaching devices and facilities are being widely used in the new round of English teaching reform. Under this circumstance, English teachers must learn more about the new teaching context, change their teaching mode, make full use of multimedia textbooks, and try to improve students' overall English abilities. Based on learning theories this article discusses how to integrate Multimedia...
As a new open-source smart mobile phone platform, Android has become one of the popular cell phone systems. Many users like to watch Video by a mobile phone, but the original media player in Android has many limits. For example, the media formats supported are few and the decode efficiency is fair. First, the paper designs a new media player system structure based on hiberarchy. Then, the paper designs...
802.11e HCCA (Hybrid coordination function Controlled Channel Access) exhibits good QoS provisioning for constant bit rate (CBR) video streams in a single collision domain. However, its performance degrades significantly for variable bit rate (VBR) video streams particularly in multi-collision domains. In addition, HCCA has the disadvantage of high complexity. In this paper, we introduce a deterministic...
QoS provisioning for video streaming over 802.11 home networks is challenging due to the tight bandwidth and delay constraints. Currently, both 802.11e HCCA and EDCA have their disadvantages when delivering video over 802.11 networks. EDCA exhibits degraded QoS performance for increased number of stations, while HCCA has high complexity, and also suffers from the impact of inter-cell interference...
