Abstract

A system and method are disclosed for preloading interactive content before it is to be displayed, thereby avoiding any unwanted delays due to download times. According to the invention, ITV data is embedded into the signal at some predetermined time before the corresponding segment will be broadcast. The ITV data is received by the ITV receiver, which then accesses an interactive site (web site or other server) and makes a request for the interactive content. The server determines the location of the content, and the content is then retrieved and transmitted to the ITV receiver. At the appropriate time (e.g., when the corresponding TV segment is being displayed), the content is displayed on the user'"'"'s display, thereby reliably providing simultaneous display of the segment and corresponding interactive content.

Claims

1-36. -36. (Cancelled)

37. A method for synchronizing display of interactive content downloaded from a remote computer, where time taken for downloading the interactive content is inconstant, the method comprising:

receiving at a receiver a first command and a second command transmitted in a television signal, the first command being inserted at a temporal location of the signal that is received a predetermined amount of time before receipt of the second command;

automatically pre-loading from the remote computer into a data store coupled to the receiver, in response to receipt of the first command, at least a portion of the interactive content, wherein the automatic pre-loading effectively avoids delays in displaying the portion of the interactive content due delays in downloading the interactive content; and

displaying the pre-loaded portion of the interactive content in response to receipt of the second command.

38. The method of claim 37, further comprising:

accessing a web server and requesting for content;

determining at the web server the location of the first remote computer; and

retrieving the interactive content from the first remote computer.

39. The method of claim 38, wherein the retrieving the content is performed by the web server.

40. The method of claim 38, further including transmitting location information to the receiver, wherein retrieving the content is performed by the receiver.

41. The method of claim 38, wherein the remote computer is a content server accessed to retrieve the content.

42. The method of claim 41, wherein the web server accesses the content server for retrieving the content.

43. The method of claim 41, wherein the receiver accesses the content server for retrieving the content.

44. The method of claim 37, wherein the first command is inserted at the time of air.

45. The method of claim 37, wherein the first command is a URL.

46. The method of claim 37, wherein the second command is a trigger.

47. The method of claim 37, further including storing the content in the data store until receipt of the second command.

48. The method of claim 38, wherein accessing the web server comprises accessing a preselected web server.

49. The method of claim 48, further including transmitting to the preselected web server information contained within the first command.

50. The method of claim 38, wherein accessing the web server comprises accessing a particular web server based on the first command.

51. The method of claim 38, wherein requesting content comprises transmitting the first command to the interactive site.

54. The system of claim 42, wherein the first server is programmed to transmit a uniform resource locator of the second server to the end user device, and the second server is responsive to receipt of the second request from the end user device to retrieve and transmit the identified interactive content to the end user device.

52. A system for synchronizing display of interactive content, the system comprising:

an end user device receiving a television signal including a first command;

a first server coupled to the end user device over a communications network; and

a plurality of second servers coupled to at least one of the first server and the end user device, characterized in that the end user device retrieves the first command from the television signal and in response, transmits a first request to the first server, the first server identifying in response to the first request interactive content stored in one of the plurality of the second servers, the second server being responsive to a second request transmitted by at least one of the first server and the end user device in response to the interactive content being identified by the first server, and transmitting the identified interactive content to the end user device for display at an appropriate time.

53. The system of claim 52, wherein the first server is programmed to establish a link to the second server, the second server is programmed to transmit the identified interactive content to the first server, and the first server is programmed to transmit the identified interactive content to the end user device.
