Definitions

  • the present invention relates to the provision of Internet data to wireless telephones and, more particularly, to a system for converting Internet streaming media, such as audio and video packets, to a format that can be used by a wireless telephone.
  • WAN and MP3 sound files can be downloaded from the Internet and then played by the user on a PC or other device.
  • Other sound files such as those created by RealAudio® software, allow the user to listen to the sounds while the file is downloading. This process is known as audio streaming.
  • Video files Users can also obtain video files via the Internet.
  • Common video formats include the MPEG format (files ending in .mpg) and Macintosh QuickTime.
  • Windows ".avi" files can be used for animation.
  • WAN and MP3 files it is typical for these video and animation files to be completely downloaded by the user and then played.
  • Other files use special software so that the user can watch the video while it is downloading. This capability is known as video streaming.
  • Streaming audio and/or video techniques provide a method of sending the audio or video data over the Internet as a continuous, compressed stream that is played for the user on the fly as it is received. Streaming allows the user to listen to or view received information almost as soon as it is received, as compared to playing downloaded audio or video files which may have a delay of several minutes while the entire file is transferred.
  • RealAudio® a widely used standard for audio streaming is RealAudio®.
  • Streaming technology not only allows users to play prerecorded audio and video files, such as books, music or videos that have been digitized and stored, but also allows users to receive live audio and video in realtime.
  • radio stations and television stations can stream their broadcasts over the Internet or any other computer network. Any other source of live or recorded audio or video can also be streamed to send users information or entertainment via the Internet. Users can listen to or watch these broadcasts using, for example, RealPlayer® software or Windows® Media Player.
  • a user selects a sound clip on the Internet, such as by clicking on a Web page link on the PC's Web browser, the link typically does not lead directly to a sound file. Instead, the Web browser contacts the Web server, which sends a metafile to the browser.
  • the metafile contains the true location (Internet/network address or Universal Resource Locator (URL)) of a server that hosts the selected sound file.
  • the metafile also contains instructions directing the Web browser to launch an audio player.
  • the audio player is a software plug-in that is designed to work with the Web browser. Once the audio player is launched, it contacts the URL contained in the metafile.
  • This URL may not be on the original Web server, but instead may be for a separate server that is designed to deliver streaming audio or video clips, such as a RealPlayer® server that delivers RealPlayer® sound clips.
  • the audio player and the streaming audio server exchange information, such as the connection speed between the user and the Internet. Higher speed or wider bandwidth connections allow the audio server to send more data, which corresponds to a higher- quality sound file and, thus, higher-quality sound played by the PC. For lower coimection rates, the sound quality may be diminished.
  • the sound file which has been compressed and encoded, is sent in LP packets using the User Datagram Protocol (UDP) instead of the more widely used Transmission Control Protocol (TCP). UDP does not resend packets if there are problems in the transmission to the user. If missing or corrupted packets were resent, the sound player would be continuously interrupted and could not play the sound clip properly.
  • the Real-time Transport Protocol RTP timestamps the packets so that missing packets can be detected and compensated for by the receiving audio or video codec.
  • the received packets are stored in a buffer on the user's PC.
  • the audio player begins playing the sound clip.
  • the audio player allows the user to move to different places in the sound clip to replay the sound or to jump ahead to a later portion of the clip.
  • the audio player contacts the streaming audio server and tells the server to start sending packets from the new position.
  • radio stations are providing live audio streaming over the Internet.
  • radio station include traditional radio stations that broadcast over the airwaves and newer "Internet radio stations" that offer Internet-only broadcasts. Music, news or other sounds are played or broadcast by the radio station.
  • the broadcast information is then converted to a digitized format that can be processed by computers and sent over the Internet.
  • These formats include the RealPlayer® and Windows® Media Player formats.
  • An Internet server hosts the live broadcast in the converted, digital format.
  • a user wants to listen to a radio broadcast via the Internet, they launch a client software radio player. From the radio player, the user either selects a link or enters a URL for the desired Internet radio broadcast. When the link is selected or clicked, the radio player software contacts the hosting server, which then sends the broadcast to the user's PC in a steady stream similar to the transmission of an audio clip. The radio broadcast is then played on the user's PC. Generally, the higher the connection speed or the wider the bandwidth, the higher the quality of the broadcast.
  • Video streaming is accomplished in basically the same manner as audio streaming. Both live video and previously stored video files can be streamed over the Internet.
  • the original video image is captured, digitized and compressed into an appropriate format.
  • interframe compression may be used so that only those pixels that change from one frame to another are transmitted.
  • the video information is stored or hosted by a video server on the Internet. Users may view video clips by using a software video player. Packets of video data are sent to the user's PC over the Internet connection using the UDP protocol. As the LP packets are received, they are buffered and then played for the user. Usually, the video information is discarded after it is played rather than being saved on the PC.
  • a special Internet high-speed backbone called the Multicast Backbone (MBone)
  • MONE Multicast Backbone
  • Transmission via the MBone uses an IP Multicast protocol instead of the TCP protocol.
  • the Multicast protocol allows the packets to be sent to many users by putting information about multiple Internet destinations within the packets. Initially, the transmission goes out as one file. As the files traverse the Internet, copies of the files are made when appropriate to ensure that the files reach each user. For example, a live video stream may be sent via the MBone to ten users that share the same Internet Service Provider (ISP). A single copy (instead often copies) of the file is sent from the video source server to the ISP's server. The ISP server then copies the files and sends a file to each of the ten requesting users.
  • ISP Internet Service Provider
  • Videoconferencing is also possible via the Internet. Two users may exchange video information directly from one Internet address to another. Alternatively, two or more users may conduct an Internet videoconference by using a "reflector" server that sends the video signals from each participant to all of the other participants.
  • Whiteboard applications which allow two or more participants to work live on the same computer display from different locations, are also possible with video streaming.
  • SMS Short Message Service
  • the source of the audio or video stream may be an Internet web server or another node on a computer network.
  • a system and method which provides an interface between streaming audio and video Internet servers and a wireless device. Broadcasters and others can provide real-time or on-demand audio and video information via the Internet.
  • the present invention provides a link between such audio or video streams and user telephones.
  • a wireless telephone user configures a user profile to identify a number of preferred services.
  • the user profile associates these preferred services with certain dialed digit strings, feature codes or telephone numbers.
  • the wireless network analyzes the dialed digits, telephone number or feature code to determine if it is associated with a preselected service in the user's profile.
  • the wireless network determines the address or URL for the server that provides the audio or video stream. A connection is established to the streaming server and the wireless network begins receiving audio or video packets via the Internet.
  • the call connection setup messages include information to link the wireless call to the received audio or video stream.
  • An interface device converts the streaming audio or video packets in to the appropriate format that can be sent by the wireless network to the telephone.
  • the streaming audio and video packets may be converted to a PCM format and the signals can be processed and sent to the wireless telephone as if they were received from the public telephone network.
  • the present invention may also be part of a wireline network, such as a private network in which calls are routed by a Private Branch Exchange (PBX).
  • PBX Private Branch Exchange
  • the dialed digits or feature codes used in the invention to initiate the streaming audio or video service may be unique for each user, such as those defined in a user profile, and/or they may be generic numbers or codes that are available for use by an subscriber to the system.
  • the present invention may be a stand alone system that can receive calls from any subscriber via the PSTN. The stand alone system determines what service is being requested by the user in any of a number of ways. For example, the system may maintain unique user profiles in a database and the system could provide the user-selected services after the caller was identified. The callers could be identified by Automatic Number Identification (ANI) information for incoming calls.
  • ANI Automatic Number Identification
  • DNIS could be used to identify the caller.

  • the present invention Upon recognizing a preselected event or time, the present invention would initiate a call to the user and simultaneous open a link to the host for the audio or video stream associated with the event or time. For example, if a financial index, such as a market average or a certain stock price, hit a certain level, then the user may be connected to a financial news service audio stream. In another example, many radio stations have an Internet web page with a streaming audio link. If a user enjoys a particular radio broadcast, then the user could configure his profile so that system establishes a connection to the streamed audio for that broadcast at the same time everyday. Thus, the user would always be able to listen to a selected program even if he was traveling.
