Definitions

  • This invention relates to communication systems using the Internet and in particular to a method for manipulating a live audio media stream providing an on-line real time custom tailored news source.
  • BACKGROUND OF THE INVENTION Every business day hundreds of millions of shares of stock representing thousands of publicly owned companies are traded by individual and institutional investors . These publicly owned companies represent a variety of industry sectors, e.g. transportation, utilities, energy, telecommunications, computer technology, retail, real estate, and health. In years past many individual investors relied on full service brokerage firms, mutual fund managers, or investment advisers for making investment decisions.
  • News items may concern the market in general, an industry sector, or a corporation.
  • the news might be statistical data on an industry sector cyclical trend, or a corporate announcement about a new product, merger, or change in executive management.
  • the news item sometimes includes the trading price of one or more related stocks .
  • Broadcast news reports i.e. television and radio
  • a viewer or listener must tune in with undivided attention in order to receive the information.
  • the information Unless the investor records the broadcast, the information generally cannot be retrieved.
  • Other problems with broadcast news are the time constraints and large target audience, which tend to result in highlight news of broad appeal. For the serious investor, real-time broadcast news does not usually provide enough detail about the stocks of interest, and therefore is not a preferred source of investment news.
  • Print media such as newspapers, provide the previous day' s trading prices for thousands of stocks and in-depth business reports.
  • the investor must devote full attention to manually searching for news that is of interest. Due to limited print space, business reports are selected based on relevance to many readers and do not provide 100% coverage of business news.
  • the news wire probably provides the most recent business news that can be easily accessed through electronic means.
  • News wire services are generally the primary source of national and world business news for the broadcast and print media. Therefore news is typically available through a news wire service before it is broadcast or printed.
  • News items are stored in computer databases and can be easily searched. However, the investor must actively perform the search and retrieve the information, diverting time and attention from other tasks.
  • the Internet gives the investor access to many sources of investment information.
  • Many financially oriented web sites provide useful services to an investor. Some of these enable a user to build a customized watch list of stock symbols, showing trading information such as price of the last trade (usually delayed 15-20 minutes), day's high and low, volume, and historical price data. Also provided are automatic links to news and research for each stock on the watch list. Many of the news links are obtained from the newswire services and are specific to that stock or its industry sector. Although the information is at the user's fingertips, it still requires time and attention to review the news links periodically to see if any new items have appeared in the list. There are other services that employ push technology to deliver information directly to the investor. One service delivers customized headline news and stock data passively to a user' s computer desktop and is accessed by opening an icon.
  • the invention is a method for manipulating a live audio media stream such as, by way of example, a PRNewswire press release.
  • a PRNewswire press release In this example, the press release is received by a News Server computer is read until one whole press release has been received. The press release story is then sent to a PRNewswire Parser.
  • the PRNewswire Parser parses through the press release to break apart the data into its individual components, i.e. headline, press release text, stock symbols, industry codes etc. This data is put into a press release object and sent to server software.
  • the server software receives the press release object and stores each of the fields of the object into a record in the database. The release is also added to an editor queue.
  • the server also manages the narrator queue, ordering the releases in the queue by priority code. This queue is populated after an editor has edited and saved a press release on one of the editor computers . Another main function of the server is to keep track of the status of all the press releases as they flow through the system, updating the statuses in the database as they change.
  • the Editor Client is the interface between an editor and the server. When an editor executes an operation (edit, skip, delete, save, or cancel) on a press release, the Editor Client makes the appropriate method call on the server software to handle the operation.
  • server software When server software handles any operation on a press release it must push information to the Editor Client to inform the Editor Client when the status of a press release has changed so that the Editor Client can update its information to the editor.
  • the Narrator Client gets the next press release to be read from the server upon the narrator "pressing" the next button on the console.
  • a call is made to the media encoder, such as a Microsoft Windows Media Encoder, to send a command and text script string through the live media stream.
  • the data sent in the stream for the "HEADLINE" type includes the stock symbol associated with the release, the industry code associated with the release, the headline of the release and the unique ID of the record in the database for this release.
  • buttons on the console there are also buttons on the console to send commands and text strings for market update, end of day and commercials.
  • the Javascript on the HTML page reads the preferences from the "cookie” and stores them in local variables; a media player is also started.
  • text string and command that was sent by the media encoder is received by the media player, the player calls a Javascript function that determines what type of command has been received.
  • the commands that are currently implemented are "HEADLINE", “MRKTUPDT” (market update) , “EOD” (end of day) and "PROMO” (for commercials).
  • the "HEADLINE” command is received, the text is decoded to get the id, stock symbol, industry code and headline text for the headline that is about to be read by the narrator.
  • the stock symbols and industry code of the release are compared against the preferences set by the user. If a match is found then a call is made to the media player to make sure the volume is turned on if the user has chosen to set it to mute.
  • the stock symbol and headline are also displayed highlighted in a scrolling table.
  • the headline text is also an active (Uniform Resource Locator) URL link to the full text of the press release on the web site.
  • the volume of the player is returned to its previous state and the headline is displayed in normal text.
  • the other commands and text strings are received the volume is turned on if it is set to mute and a message is displayed to the user.
  • An objective of the invention is to disclose a method for manipulating a live audio media stream. Another objective of the invention is to disclose a method for providing an on-line real time custom tailored news source. Still another objective of the invention is to provide a news source that will automatically provide an investor with critical news on selected holdings by parsing a news text feed into individual components and providing queue to determine a priority order of media releases. Another objective of the invention is to compare media releases to user preferences and, manipulate the volume of a media player based upon matching of user preferences and also highlighting the headline of said media release when matched against the user preferences. Still another objective of the invention is to provide an active URL link to the full text of a media release.

Abstract

L'invention concerne un procédé pour manipuler un flux audio en direct. On crée un flux audio en direct et codé à partir d'un texte d'informations qui a été parsé en des composants individuels tels que le titre, le texte des informations, les symboles et le code d'activité économique. Les composés sont stockés afin d'être comparés aux entrées introduites par l'utilisateur. Lorsque l'ordinateur d'un utilisateur reçoit le flux audio multimédia en direct, ce flux multimédia est décodé; si les codes d'activité économique et les symboles correspondent aux préférences de l'utilisateur, le volume du lecteur multimédia de l'ordinateur utilisateur est augmenté, et le titre est affiché sous forme de texte en surbrillance dans une table de défilement. Le texte du titre constitue également un lien URL actif vers le texte complet du communiqué de presse sur un site Web. Lorsqu'arrive la prochaine édition et qu'il n'y a pas de correspondance avec les préférences, le volume du lecteur est baissé jusqu'au niveau initial et le titre est affiché sous forme de texte normal.
