Definitions

  • This invention relates to a method and apparatus for processing a digital program, and more particularly, to a playing back method and apparatus for a digital TV program.
  • a digital interactive TV (iTV) program includes not only audiovisual contents but also interactive applications. Some interactive applications have the ability to access a network or get data through a network connection.
  • a set top box (STB) with storage or an interactive TV recorder can record the iTV program to a storage medium, which can be a hard disk or an optical disc such as DVD + RW disc or Blu-ray disc. The recorder can directly record the iTV program without playing back it.
  • Network service provides individuation to users, and the users can choose to view the interested item. This is one feature different from the broadcast. Broadcaster could charge for providing some extra services or use these services to attract customs.
  • One example for the broadcaster to use network data is a multi-angle program. For example, during a football match, there can be a multi-angle program. When there are some highlights, users may want to view them from different angles and usually there are multiple cameras in the field to track the whole match. Broadcasting all the programs from different angles at same time will cost much because of the bandwidth usage, and some users may want to view the different angles but some others do not.
  • a good way to solve this problem is to broadcast the main angle on broadcast channel and put other angles on a network server, and users view these angles as they want. The broadcaster can charge for this access or use this feature to attract users.
  • the interactive program will determine the display of these angles. They can be showed as picture in picture or in full screen.
  • Recording of a TV program is a natural requirement from users. Users want to record a digital TV program by using a PDR as to record an analog TV program by using a VCR. When users watch a TV program and find that is relatively interesting, the users want to record such TV program.
  • the command to access network is started by the interactive application. For example, a network server can be accessed by the application, so as to get some image files for displaying from the server.
  • the recorder fails to know that the iTV programs will access network. Thus, the recorder would not record the network data.
  • the network data directed by the network link provided together with the iTV program will not be available at certain time after live broadcasting. If the recorder does not record the network data during live broadcasting, the playing back of the recoded iTV program may not be made as the users normally expected.
  • An object of the invention is to provide a method and apparatus for playing back a digital program, which method and apparatus can get the network data related to such program when it is being played back, so as to record the network data in a local storage.
  • Another object of the invention is to provide a method and apparatus for reproducing a digital program, which method and apparatus can conveniently play back the digital program recorded in a local storage.

  • Instructing a personal computer to execute corresponding downloading process is based on the following consideration.
  • the network navigation sometimes does not conform to the activities of watching the digital program such as iTV. Some web pages may have poor displaying effect on TV sets. Even some TV sets do not support the newest web format. However, Broadcaster always tries to provide some extra data contents via iTV program to attract TV audiences to access a specific web site.
  • the broadcaster may insert certain graphics or texts (not the actual URL) into the iTV program, to provide them to the TV audiences with the transport stream.
  • the TV audiences can select to watch or download the web contents (hereinbefore referred as to "network data") linked with those graphics or texts. It is not convenient for some web contents (such as "flash" files) to be played back on TV sets. Therefore, users can select to download such web contents into apparatus (such as personal computer) which is adapted to play back those contents, so as to can view them later.
