Abstract: An intermediate casing for a turbojet fan compartment, including: a shroud centered along a longitudinal axis of the turbine engine; an annular cheek plate centered along the longitudinal axis of the turbine engine and mounted against a downstream face of the shroud; a suspension beam fastened to the cheek plate and extending downstream parallel to the longitudinal axis of the turbine engine; and an AGB suspended from the beam and including an upstream side face spaced apart axially from the cheek plate, a downstream side face opposite the upstream side face, and a plurality of accessories mounted against its downstream side face and distributed about the longitudinal axis of the turbine engine.

Abstract: A by-pass turbojet including a thrust reverser is disclosed. The thrust reverse includes a deflector device which deflects all or part of the primary stream gas in such a manner that the deflected primary stream gas encounters the secondary stream, thereby reducing the injection speed of the secondary stream in an aft direction, and thus generating the thrust-reversal effect. The secondary stream escapes from the aft end of the nacelle. In the thrust-reversal position, the deflector device is inscribed radially substantially within the section of the primary nozzle cowl at the aft end of the nacelle. Such a thrust reverser is particularly simple in design, inexpensive, and makes it possible to avoid having moving parts present on the outside portion of the nacelle, thus simplifying the design of the turbojet.

Abstract: A client device receives a broadcast content signal containing an interactive identifier over a managed network at a client device. The interactive identifier may be a trigger that is included in a header or embedded within the digital video data. The trigger may have a temporal component, wherein the trigger can expire after a certain period of time. In response to identification of the trigger, the client device sends a user request for interactive content over an unmanaged network. For example, the managed network may be a one-way satellite television network, IP-television network or cable television network and the unmanaged network may be the Internet. The client device switches between receiving data from the managed network to receiving data from the unmanaged network.

Abstract: A method, system, and computer program product for providing a decoy identifier, such as an MPEG PID, for a non-encrypted component. By obscuring the true identifier, an MPEG receiver that can decode ‘clear channels’ can not locate, and therefore, can not decode and present the true component for the program to a display device. By using the disclosed methodology, computer program product and system a cable television system or other provider of individualized content can broadcast a requested component without needing to encrypt the component.

Abstract: Efficient messaging techniques that facilitate interactive program guide (IPG) delivery and allow a terminal to specifically designate requested items of information from a server. The IPG can be provided via a number of IPG pages, with each page including a number of defined regions. In one method, selection for a particular region of a particular page is received at a terminal and a determination is made whether the selected region is currently received. If the answer is no, a request for the selected region is generated and sent to a server. The request can conform to a particular message format that includes a number of fields, e.g., a region ID field that identifies the selected region, a subtype field that identifies a particular type, a time slot field that identifies a specific time slot, and a page offset field that identifies a specific page from among many.

Abstract: A system and method for efficient delivery of video segments. One embodiment relates to the delivery of short-time duration video segments. The video segments may be delivered as part of a media-rich interactive program guide (IPG) or for some other application. The system and method provides a viewer with access to a video segment starting at its beginning (or any other selectable point within the video segment). Such access may be provided using a server-centric interactive technique. The server-centric technique may involve use of a demand-cast system and method. Demand-cast messaging may occur between a session manager, transport stream generator, and terminal. For example, a video object on a screen may be activated by a viewer using a remote control for a terminal. Activation of the object may cause transmission of a request from the terminal to a session manager for a video segment corresponding to the object.

Abstract: Techniques to create, generate, and deliver customized interactive program guide (custom-IPG). In one embodiment, selections indicative of a set of channels to be included in the custom-IPG are received. In response, one or more custom-IPG screens including the set of selected channels are rendered at a headend. Custom-IPG screens can be formed as subsets of the regular IPG screens, or as new screens. The rendered custom-IPG screens are provided from the head end to a set top terminal upon receiving a viewer request for the custom-IPG. Commands indicative of a particular location at which to overlay the custom-IPG screens may also be received, and the custom-IPG screens are re-rendered at the indicated location. Custom-IPG screens can be overlaid on a video sequence provided on a particular channel being viewed, used to carry regular program guide, or a channel independent of the channel used to carry regular programming and program guide.

Abstract: A terminal for decoding and presenting encoded realtime and non-realtime interactive program guide (IPG) content including a realtime video portion and a non-realtime guide graphics portion. The terminal includes a demodulator operative to receive and demodulate a modulated signal to provide a transport stream, and a transport demultiplexer coupled to the demodulator and operative to receive and process the transport stream to provide a sequence of transport packets re-timestamped to synchronize encoded realtime content and encoded non-realtime content included therein. At least one video decoder is coupled to the transport demultiplexer and operative to receive and decode the encoded realtime and non-realtime contents to recover the realtime and non-realtime contents for the user interface.
