摘要： The invention provides an apparatus and a method for improving the control of access by a terminal device in a WLAN environment having an access point for determining whether the device utilizes an IEEE 802.1x protocol by the access point communicating to the device, a packet, whereby if the devices utilizes a IEEE 802.1x protocol the device appropriately responds and otherwise the access point determines that the terminal device protocol does not employ a IEEE 802.1x protocol and selects an authentication mechanism compatible with the terminal device. If the device is not an IEEE 802.1x client, an IP packet filtering is configured to redirect a user HTTP request to a local server, and when the HTTP requests are thereby redirected, the HTTP server presents the terminal device with information specifically related to the browser based authentication.

摘要： A method and system for caching data such as audio, video and/or other data uses information including future access request information for improved caching performance. According to an exemplary embodiment, a cache system (20) includes a cache (22) operative to cache a plurality of data items. A processor (28) is operative to enable at least one of the data items in the cache (22) to be replaced using future access request information for the at least one data item.

摘要： A wireless Local Area Network provides data service through a data LAN and also provides video broadcast service through a video LAN. A wireless LAN subscriber accesses the video LAN through one of a plurality of Video Access Points (VAPs) that broadcast multiple video programs on a channel having a frequency different than the frequency over which the subscriber accesses the data LAN. Each VAP maintains the video channel in a one-way broadcast-only mode to prevent a wireless LAN subscriber from seeking to uplink information on that channel. In this way, the wireless LAN can employ a common protocol for both data and video transmission, and deliver the video streams at the maximum permissible downlink transmission rate.

摘要： In a communications system ( 10 ), activation of a user interface (e.g., a hyperlink) to select an application depends on one or more conditions that might impact the application. Monitoring of the condition(s) occurs to determine whether each condition falls outside a corresponding threshold. If so, the interface is constrained, either partially or completely.

摘要： A method for mapping from an MPEG-2 transport stream to an IP-based RTP/UDP/IP stack for broadcasting service in a WLAN. All the mapping functions may be performed in a receiver transcoder (FIG. 2). Mobile devices such as laptop computers, cell phones and PDAs have limited battery power, CPU processing and memory resources. To reduce CPU processing power and consumption battery power in these devices certain data processing functions are achieved in the communicating systems, such as the de-multiplexer function that typically prepares an MPEG-2 for retransmission at the local level. When a transcoder, capable of de-multiplexing and MPEG-2 transport stream receives a program it de-multiplexes the stream based on PIDs assigned to each transport packet. This de-multiplexing function extracts several components from a transport stream: video and audio PES/ES associated with programs and PSI (PAT and PMTs).
