Multi-Room IPTV Delivery through Pseudo-Broadcast over IEEE 802.11 Links

摘要: The IEEE 802.11 wireless LAN (WLAN) is a timetested technology, but it still evolving towards even higher speeds and richer features. For multi-room IPTV delivery, where multiple IPTVs are fed from main set-top box (STB), the WLAN an attractive choice for wirelessly connecting STB IPTVs. In this paper, however, we first show that both standard unicast broadcast/multicast delivery mechanisms have efficiency reliability issues when they applied to delivery. order resolve issues, propose use so called pseudo-broadcast, transmission promiscuously received by receivers. By dynamically changing destination based on 802.11k measurement, scheme also minimizes losses experienced promiscuous can be implemented without any change in standard, provides cost-effective solution high-reliability highefficiency
