Embodiment Construction
[0024] An embodiment of the present invention is described in detail below. In this embodiment, the interactive television system transmits an audio-visual interactive signal from a broadcast station to a receiving station via a broadcast channel (here "broadcast" is used to mean sending a single signal to all subscriber receivers). The broadcast channel may comprise a direct satellite transmission channel or any known means including non-satellite, cable, MMDS (microwave) and land-based transmitted broadcast signals. (As used herein a "direct" satellite transmission means a transmission received directly from a satellite using an interactive television receiver). In this embodiment the receiving station is additionally configured to receive signals via a modem connected to the broadcasting station.
[0025] Audio-visual interactive signals broadcast to receiving stations may contain television programs and interactive information such as control signals or interactive applic...

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.
Description
technical field [0001] The present invention relates generally to interactive television systems, and more particularly to apparatus and methods for converting user-supplied information by a server into a data format usable by interactive television applications. Background technique [0002] Interactive television systems can be used to provide various services to users. Such systems are capable of displaying text and graphic images for viewer interaction, as well as audio and video streams associated with common television programming. Interactive television systems enable viewers to interact and thus enable the system to be used for sales and education in addition to expanding the entertainment capabilities of ordinary television. Viewers may order an advertised product or service, request information about a particular program, or send electronic messages (e-mail). [0003] In a typical interactive television system, a broadcast service provider generates an interactiv...
