摘要： A wireless Local Area Network (10) provides data service through a data LAN (14) and also provides video broadcast service through a video LAN (26). A wireless LAN subscriber accesses the video LAN through one of a plurality of Video Access Points (VAPs) (281 and 282) 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： A satellite communications system comprises a transmitter, a satellite transponder and a receiver. The transmitter transmits an uplink multi-level modulated signal (hierarchical modulation, layered modulation, etc.) to the satellite transponder, which broadcasts the multi-level modulated signal downlink to one, or more, receivers. The multi-level modulated signal comprises an upper layer and a lower layer. The lower layer conveys LDPC blocks, or LDPC frames, each LDPC block comprising S bits of data including a header portion and a data-bearing portion. The upper layer conveys shorter blocks, each shorter block comprising R bits of data, where R

摘要： A method and apparatus for staggercasting includes encoding a first signal representing content having a time duration and a second signal also representing that content. A time delay period is specified for the time duration of the content. A composite signal, comprising the first and second encoded signals, is generated. In the composite signal the first encoded signal is delayed with respect to the second encoded signal by the time delay period for the time duration of the content. If an error is detected in the composite signal, then the received second encoded signal is decoded to produce the content, otherwise the delayed received first encoded signal is decoded to produce the content.

摘要： A method for staggercasting, includes encoding a first signal representing content using encoding having successive independent decoding segments and encoding a second signal representing the content using encoding having successive independent decoding segments respectively corresponding to the independent decoding segments of the first encoded signal. A composite signal including the first and second encoded signals is generated in which the first encoded signal is delayed with respect to the second encoded signal. If an error is detected in the composite signal during a portion of an independent decoding segment of the delayed first encoded signal, then the corresponding independent decoding segment of the received second encoded signal is decoded to produce the content, otherwise, the received delayed first encoded signal is decoded to produce the content.

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 (240) that typically prepares an MPEG-2 for retransmission at the local level. When a transcoder, capable of de-multiplexing an MPEG-2 transport stream (105) receives a program it de-multiplexes the stream based on PIDs (204) assigned to each transport packet. This de-multiplexing function extracts several components from a transport stream: video and audio PES/ES (112, 212) associated with programs and PSI (203) (PAT (204, 251) and PMTs (206, 258)).

摘要： A method for downloading and displaying a video program using a mobile terminal in an interworking environment that includes a first radio access network having a first data transfer rate and a second radio access network having a second data transfer rate faster than the first data transfer rate. The video program is downloaded through the first or second networks at the first or second transfer rate, respectively. The downloaded video program is displayed at a predetermined playback rate. Excess portions of the downloaded video program that result when a rate at which the video program is downloaded exceeds the predetermined playback rate are buffered. A third data transfer rate that is lower than the first transfer rate is calculated in response to the predetermined playback rate, the buffered excess portions and the time duration of the remainder of the video program. The third data transfer rate is negotiated with the first network for downloading the video program when the difference between first and third data transfer rates exceeds a threshold level.

摘要： A public wireless LAN (11) permits receipt of non-authentication traffic, such as access information requests, from a mobile wireless communications device (121) prior to device authentication by partially opening a controlled port within an access point (181). The wireless LAN re-directs such non-authentication traffic received at the AP from the mobile wireless communications to a local web server (21). The local web server provides reply to the mobile wireless communications device, enabling a determination by the device whether or not to request access. The device seeks access by way of an access request received at the AP. In response, the AP re-directs the access request through an uncontrolled port in the AP to an access server (26) that authenticates device. Upon successful device authentication, the AP fully opens its controlled port to permit the exchange of traffic through that port with the mobile wireless communications device.

摘要： A system, apparatus and/or method provides frequency response adjustment of an RF input filter of an RF tuner based on impedance of an antenna system that is providing reception of RF signals to the RF tuner. The frequency response adjustment is preferably accomplished dynamically and/or with respect to each frequency tuned. Particularly, the system, method and/or apparatus provides compensation at the RF tuner level for mistuning effects produced on the RF tuner by antenna system impedance presented at the antenna input that is other than a designed for impedance. Frequency response of an RF input filter for the RF tuner is electronically adjustable with an independent or semi-independent control voltage signal based on one or more measured parameters of a tuning frequency. Frequency response adjustment may include adjustment of a center frequency of the RF input filter bandpass frequency range and/or altering the bandpass frequency range of the RF input filter. The subject invention expands the capability of an RF signal receiver, particularly one using at least one electronically adjustable RF filter at the input of an electronic alignment type tuner.
