摘要： A chat room is broadcast in an interactive television environment for lurking 'in' a chat room, without the need for establishing a back channel connection. The present invention provides a mode of chat room broadcasting and communication that can be easily handled by a client device, typically a set top box (STB) processor, an interactive television server and its subscriber clients. The present invention broadcasts chat rooms to clients who may either connect through a back channel to participate in a chat room or simply lurk, that is, to watch the chat room content and discussion in the broadcast without participating or registering in the chat room.

摘要： A method and mechanism for repositioning video images in a compressed data stream without requiring bit shifting. A P frame image is to be repositioned from an original position to an alternate position. The P frame image data is analyzed (1102) to determine whether the repositioning will result in the image data bit positions being changed with respect to the original image (1106). In response to determining the bit positions will be changed, the original image data is modified by adding stuffing bits in the form of a stuffing macroblock to restore the image data to its original bit positions. The P frame is intra-coded and the stuffing macroblock (1114) is non-intra coded. A non-intra quantization matrix is selected such that upon decode the stuffing macroblock data does not adversely affect the final picture. Maintaining the original bits positions of the image data facilitates a straightforward copy of unmodified data from the original P frame to the new P frame.

摘要： A system and method for providing user input to an application executing on an interactive television system wherein a user provides non-textual information to the interactive television system and this information is converted by a server to textual information which is provided to the application. In one embodiment, a digitizer pad coupled to a set-top box is used to digitize the user's handwriting. The digitized information is conveyed to a remote server which converts the digitized handwriting data into textual information. The textual information is conveyed to the set-top box, where it is input to an application executing on the set-top box. In another embodiment, a microphone is coupled to a set-top box. The microphone allows the user to input voice information which is digitized and conveyed to the server for conversion into textual information. The textual information is conveyed back to the set-top box and is input to an application executing on the set-top box.

摘要： In an audio video interactive (AVI) receiver receiving a packet stream including a directory and an AVI program having an associated identifier in the directory, a method is disclosed for controlling the execution of the AVI program comprises the following steps. First, loading the AVI program into a memory in response to the presence of the AVI program in the packet stream. Then beginning execution of the loaded AVI program. And then minimizing the executing AVI program when a directory identifying a different AVI program is detected in the packet stream.

摘要： A system and method which displays a graphical icon, such as a slider bar, on a subscriber's television or display unit for indexing to different positions in a video stream in an interactive video delivery system. The interactive video delivery system preferably comprises at least one media server which stores one or more video streams, and one or more subscribers which each include a display device, such as a television. The television displays a slider bar or other graphical icon, and the slider bar is used to index to different locations in the video stream. During video delivery, the user may use or adjust a knob on the slider bar, preferably using a remote control device, to indicate a desire to 'jump' to a different location in the movie or video stream. The media server receives the slider bar user input from the subscriber device and begins outputting the normal play stream at the desired position.

摘要： A system and method for reprogramming a device using programming data that is transmitted over a broadcast network. In one embodiment, a smart toy works cooperatively with an interactive television system to provide an easy-to-use means for reprogramming the toy. The interactive television system has a broadcast station that transmits a carousel of data modules over a unidirectional broadcast link to a group of receiving stations. A radio frequency (RF) transceiver in the receiving station and a corresponding transceiver in the toy provide a bidirectional communications link communicates over which the data modules are transmitted from the receiving station to the toy. The data modules (e.g., data files or application code) are used to reprogram the smart toy. Particular ones of the data modules are selected, either manually or by filtering them according to user preferences, and the toy is reprogrammed with the selected modules. The user preferences can be explicitly entered or they can be constructed by the system according to the use of the toy. The toy can serve as an input device for uploading user preferences or other data to the receiving station or broadcast station. The receiving station can transmit signals to the toy, which can then provide notifications or cues to a user.
