Title: Internet television broadcast system

Description:
RELATED APPLICATIONS  
      This application claims priority to U.S. Prov. No. 60/586,827, filed Jul. 9, 2004, incorporated herein by reference. 
    
    
     FIELD  
      The invention relates to the general field of an Internet television broadcast system. In particular, the invention receives local television programming and then serves that programming to subscribers over the Internet.  
     BACKGROUND  
      Television programming is typically subject to local reception. Conventional television reception is by aerial that can pick up television signals from stations located in the same city.  
      Cable television can now broadcast national stations and programs to subscribers. For example, subscribers all over the country can receive the same CNN broadcast over their cable television. Likewise, satellite television subscribers can receive programs from all over the world.  
      However, these two types of broadcast are subject to the programming whims of the cable and satellite providers and do not permit people to see some programs which they may desire to see or to receive programs where there is no cable or satellite signal reception. Also, there is no technique for Internet carriers like SBC or AOL to offer television programming to their subscribers.  
      What is needed is an Internet television broadcast system that permits subscribers to log onto the Internet and access television programming from around the world in real time, quasi real time or on a delayed basis.  
     SUMMARY  
      The invention relates to the general field of an Internet television broadcast system that permits subscribers to log onto the Internet and access television programming from around the world in real time, quasi real time or on a delayed basis.  
      An exemplary embodiment of an Internet television broadcast system comprises a plurality of television receivers for receiving signals from a plurality of television transmitters. A processor is coupled to the television receivers and configured to selectively store television programs on a storage device and the selectively retrieve television programs from the storage device, and configured to selectively bypass the storage device. An Internet interface coupled to the processor and configured to couple to the Internet. The processor is configured to execute a program to selectively deliver requested television programs to subscribers over the Internet.  
      Advantages of the invention include the ability to view television programs over the Internet.

     DETAILED DESCRIPTION  
      The invention is described with reference to specific apparatus and embodiments. Those skilled in the art will recognize that the description is for illustration and to provide the best mode of practicing the invention.  
      The invention relates to the general field of an Internet television broadcast system. In particular, the invention receives local television programming and then serves that programming to subscribers over the Internet.  
       FIG. 1  is an architectural view of an Internet television broadcast system  100  according to an embodiment of the invention. A plurality of television stations  100   a - 110   c  are dispersed at geographically diverse locations such as in difference cities. Additionally, television stations can be delivered via satellite  120   a . An Internet television (ITV) server  320  receives the signals from the various television stations and manages the programming. In one aspect of the invention, the server  320  stores the programming in Data Storage  328 .  
      The server  320  is coupled to the Internet  400  and can deliver the television programs to subscribers  510   a - 510   n  via the Internet. In one aspect of the invention, the television programs are delivered in real time or close to real time. In another aspect of the invention, the television programs are stored in the Data Storage  328  and delivered to subscribers  510   a - 510   n  at later times or on demand.  
       FIG. 2  depicts an Internet television server  320  according to an embodiment of the invention. The server includes a television network interface  324 , which is adapted to receive signals from receivers. The receivers can include one or more of aerial television receivers, cable television receivers, satellite television receivers and/or other types of television receivers. A processor  322  is coupled to the interface  324  and processes the signals. In one aspect, the signals are digitized and encoded in a moving picture format such as MPEG. The MPEG signals can be stored in disk  328  or transmitted over Internet interface  326 .  
      Subscribers  510   a - 510   n  typically communicate over the Internet with the ITV server to request delivery of television programs either in a real time or quasi real time basis, or stored and delivered on demand. The server typically streams the content to the subscribers in a compressed format, for example, MPEG. The subscribers will have a set top box or computer processor that can decode the content from the compressed format.  
      The ITV server manages the users, user interface and billing and payment. The subscribers typically subscribe to a particular type of access and the ITV server controls and grants the access. The ITV server also tracks the usage for payment of licensing fees to providers of content such as the television stations, cable stations (such as HBO and pay-per view, etc.), satellite stations, and other content providers (movie studios, etc.).  
       FIG. 3  depicts an architectural view of an Internet television broadcast system according to an embodiment of the invention. In this embodiment, a number of ITV receivers are located at geographically diverse locations and convert the television programming to a format that is sent over the Internet to the ITV server  620  for delivery to the subscribers.  
      In one embodiment, the data storage  328  includes paid content that subscribers can view on a paid basis, for example, movies, etc.  
      In other embodiments, an ITV server can be located at a subscriber residence for recording and/or download and storage of digital content. A recording of specific content or a time period can be specified in advance or programmed by a web interface over the Internet. Likewise, programming can also be accomplished over the television interface by a remote control or other suitable user device. The storage device can be programmed by a subscriber to record television programs by date and time or by title of the program.  
      In other embodiments, the storage device employs digital rights management to ensure the integrity of copyrighted content. This is particularly important when a content owner is concerned about maintaining the integrity of content and ensuring distribution only to subscribers who are entitled to access the content.  
      Advantages of the invention include the ability to view television programs over the Internet.  
      Having disclosed exemplary embodiments and the best mode, modifications and variations may be made to the disclosed embodiments while remaining within the subject and spirit of the invention as defined by the following claims.
