It should be noted, however, that although television system 200 is used in the embodiment illustrated in Figure 2, any system capable of receiving broadcast stream 202 may be used, including radio systems.
  • Television system 200 typically includes a receiver for receiving a broadcast signal, a display screen, a tuner for extracting a television signal corresponding to a channel, and other standard components well known to those skilled in the art of television systems.
  • television system 200 also includes a set-top box (not shown in this view).

  • the ROM includes instructions and data for executing on the CPU.
  • the RAM is used for storing program variables for the program instructions contained in the ROM.
  • the set-top box of the present invention also contains executable code, typically in software, for determining at what point to insert recorded media 213 into a broadcast stream 202 based on a comparison of priority indicators 240 in the recorded media insertion 213 and in the broadcast stream 202 in a manner that will be described in detail below.
  • set-top box receives the broadcast stream 202 transmitted from a broadcast station 201 and delivers the broadcast stream 202 in real-time usable form to the receiver (not shown in this view) in the television system 200.
  • event 212 occurs, which requires the insertion of the recorded media 213 into the broadcast stream 202.
  • the media may be a recorded announcement, overlay, text, video, or any other type of available media.
  • the event 212 which triggers the recorded media insertion 213 into the broadcast stream 202 may be a variety of events, such as notification to a user of the television system 200 that an e-mail message has arrived, information regarding traffic or weather conditions, the state of the stock market, sports updates, etc.
  • the recorded media insertion 213 and the broadcast stream 202 are assigned priority indicators 240 ranging between "0,” the highest priority, and "n,” the lowest priority. There may be any number of levels between 0 and n, or only one level. Of course, priority indicators 240 do not necessarily have to range between 0 and n. In another embodiment, for instance, priority indicators 240 may range from “1” through “9,” “A” through “Z,” or may even be symbols such as "*" for the highest priority and "-” for the lowest priority. Priority indicators 240 may be embedded into the broadcast stream 202 according to numerous known technologies, including a pilot tone or by watermarking either video, audio, or other media or data transmitted.
  • a signal (not shown in this view) that is needed to change the priority indicators 240 may be programmed by a time mark. In this way, the recorded media insertion 213 synchronizes with the broadcast stream 202. It should also be noted that it is possible to use existing transport streams (such as the transport streams in digital television broadcasts) to embed the priority indicators 240 into the broadcast stream 202.
  • the priority indicators 240 of various components of the broadcast stream 202 may be annotated by a broadcaster.
  • the broadcaster may assign different priority indicators 240 to various segments of a newscast, such as priority indicator 0 to the actual program and priority indicator n to the commercials.
  • Advertisers could also use the system for low-level local advertising during the newscast (or other program), for example, by allowing an advertiser to address just one subdivision of a population group or some geographic area located close to a specific store or service place. This kind of micro-advertising would allow broadcasters to sell inexpensive local advertising to businesses, which otherwise would not have a chance to get onto a major channel during prime-time. It is also possible for the user to assign priority indicators 240 to the recorded media insertion 213.
  • the user may determine that all e-mail notifications from family members receive priority indicator 0 and all e-mail notifications from friends receive priority indicator n.
  • the user may set for each level and each media type an ignore or a higher level to replace the broadcast stream, thus allowing the user to customize the experience.
  • priority indicators 240 in the broadcast stream 202 may be transmitted over a separate network (e.g., the Internet) (not shown in this view).
  • set-top box is connected to a server (not shown in this view) through the separate network.
  • the server receives the priority indictor 240 of the broadcast stream 202 through the separate network and transmits the priority indicator 240 to the set-top box, rather than having the priority indicators 240 be embedded into the broadcast stream 202 through a watermark or some other method.
  • the recorded media insertion 213 may either be transmitted in advance, using the same transport as is used by the program information, or may be transmitted over the separate network.
  • Prerecorded announcement 242 When watermark 220 arrives, vector 221 changes the priority indicator 240 at point 241 to level 1, which in turn releases a prerecorded announcement 242 for play by sending command 222 and suspending the replay or reducing the replay of the broadcast stream 202.
  • Prerecorded announcement 242 is then inserted or overlaid, depending again on the medium type and the announcement content.
  • Prerecorded announcement 242 may be, for example, a voice-over such as "You've got mail,” that plays during a speaking pause in the program or it may be an overlay in the background of a video such as "Order your movie tickets now — Click here," generated as text and displayed on the television screen.
  • the television system 200 returns to its original broadcast-only type performance as indicated by arrows 226, 227, and 242 a through n.
  • the earlier event 242a indicates that the media insertion 213 has stopped before the second watermark 225 is sent.
  • Non-conventional media may also be used.
  • odor media not currently available, may be used to allow broadcasters to combine smells in broadcasts.
  • Odor media may be used to advertise products (such as perfume, for instance, or pizza), to notify a user that their restaurant take-out meal is available, or in any other capacity where the release of an odor may be helpful.
  • the recorded media insertion 213 may be multi-media in nature. Depending on the required interrupt priority indicator 240, some recorded media insertion 213 may be played, while others may be held back. For example, "You've got mail" may be both a video clip and a sound file.
  • a queue of recorded media insertions 213 may build, which eventually may be played, one at a time, or in a multiple view screen, showing all the icons/media at the same time, based on user requests.
  • FIG. 3 there is shown a flow chart illustrating executing code to compare the priority indicator of a recorded media insertion with the priority indicator in a broadcast stream 300 in accordance with one embodiment.
  • Broadcast stream 310 e.g., a TV program
  • recorded media insertion 320 has an assigned priority indicator B. Both priority indicator A and priority indicator B are functions of time A(t) and B(t).
  • the executing code 330 compares A(t) and B(t) (processing block 340). If A(t) is greater than B(t) then the broadcast stream is not interrupted. Otherwise, an additional recorded media insertion 350 is superimposed on the broadcast stream.
  • FIG. 4 there is shown a flow chart of the steps for comparing priority indicators of a broadcast stream with priority indicators of multiple recorded media insertions 400 in accordance with one embodiment.
  • One or more events 401 that require media insertions into a broadcast stream 402 trigger the initiation of the routine 400 (for example, through an interrupt as is well known in the art).
  • priority indicators for events 401 that trigger media insertions are called up. For instance, e-mail notifications may have a low priority indicator and phone call notifications may have a high priority indicator.
  • Priority indicators of the media insertions are decoded as are the priority indicators of the broadcast stream 402 (processing block 404).
  • the routine 400 applies filter criteria (processing block 405) where a user may set their own preferences for events 401 triggering the media insertions (processing block 405). For instance, the user may give the highest priority indicator to media insertions for an event caused by a particular person causing the event (for instance, the highest priority indicator may be given to all e-mail notifications and phone call notifications from a user's spouse).
  • the routine 400 sorts media insertions by priority indicators, such that media insertions go through a loop (processing blocks 407 and 408). The loop compares the priority indicators of multiple media insertions against the priority indicators of the broadcast stream 402.
  • the loop allows for media insertions into the broadcast stream 402 until an event with a media insertion with a lower priority than the broadcast stream 402 appears.
  • the system 400 sorts (processing block 406) the media insertions by placing media insertions with the highest priority first. When all the media insertions have played, the routine interrupts (processing block 430) and a CPU (not shown in this view) that contains routine 400 returns to its original function.
