摘要： A wireless local area network (WLAN) adheres to ANSI/IEEE 802.11 standards and communicates with user terminals (UTs) in a coverage region. The WLAN communicates video and audio to the mobile terminals over a downlink channel. In order to maximize quality of service, the system provides for a method of inhibiting the mobiles terminals from attempting to gain control of the downlink channel during transmission of program information. In particular, the WLAN access point transmits data frames that are separated in inter-frame time period that is shorter than a first inter-frame period defined by the communications standard for allowing a device to gain control of the transmission channel.

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： 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).

摘要： A mobile wireless terminal, upon transitioning from a wireless telephony network to a wireless Local Area Network (LAN), seeks identification by sending the same identity information used for identification in the wireless telephony network. Upon receipt of the identity information, a wireless LAN Access Server in the wireless telephony network identifies a Serving General Packet Radio Service Serving Node (SGSN) that had last served the wireless terminal in the wireless telephony network prior to transition. The wireless LAN Access Server forwards the identity information to the SGSN, which, in turn, provides an identification response for validating the terminal.

摘要： A method for evaluating an available bitrate over a path among one of at least two paths linking a first endpoint and a second endpoint, the path being called an evaluation path, is disclosed. The first endpoint is configured for sending data packets to the second endpoint, the second endpoint is configured for sending at each data packet reception an acknowledgment message to the first endpoint through one of the at least two path selected at each data packet reception. The method comprises, at the first endpoint, steps of: inserting a flag in a first data packet out of the data packets to be transmitted to the second endpoint through the evaluation path; sending said first data packet through the evaluation path; measuring and recording a sending time of the first data packet from said first endpoint; receiving an acknowledgment message sent by the second endpoint through the evaluation path for acknowledging reception of the first data packet at said second endpoint; measuring and recording an arrival time of said acknowledgment message at said first endpoint; assessing the available bitrate from an interval between the sending time and the arrival time and from the size of said first data packet. A method for sending at a second endpoint an acknowledgement message over a path among one of at least two paths linking a first endpoint and said second endpoint is further disclosed. Associated device for evaluating an available bitrate and device for sending at a second endpoint an acknowledgement message are disclosed.

摘要： The present invention concerns an adaptive streaming method, at a client device, for receiving content split into chunks corresponding to a content duration, the chunks being encoded at a server into at least a first and a second formats, the first format corresponding to a better content rendering quality level than the second format, a chunk being received during a chunk reception period. According to the invention, the method comprises the steps of measuring the available bandwidth between the client and the server for the next chunk reception period, requesting the server to send a chunk encoded at a format so that the chunk can be received during the next chunk reception period, and if some bandwidth is available for the next chunk reception period, requesting the server to send a part of a chunk encoded at a second format, the chunk having been received encoded at the first format.

摘要： The present invention provides apparatus and methods for measuring multimedia demand and for maximizing broadcast channel utilization. A first, two way communications channel or channels, from a customer to a broadcaster are provided, as well as a second broadcast channel, which may be, in some embodiments, combined with the two way channel. A bid cycle is established for available programs, whereby one or more programs is listed as available on said two way channel, whereupon one or more customers may bid on those programs in order to view those programs. If the aggregated bids reached a threshold value, the broadcaster will then broadcast the program to the bidding customers, thus closing the bid cycle. If the threshold is not reached, the bid cycle is unsatisfied.
