System and method for transmitting and displaying interactive TV content
InactiveUS20050005303A1Avoiding any unwanted delayReliably of contentDigital data information retrievalBroadcast information characterisationInteractive contentDisplay device
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.

It is an object of the present invention to provide a technology for manufacturing a highly reliable display device at a low cost with high yield. In the present invention, a spacer is formed over a pixel electrode, thereby protecting the pixel electrode layer from a mask in formation of an electroluminescent layer. In addition, since a layer that includes an organic material that has water permeability is sealed in a display device with a sealing material and the sealing material and the layer that includes the organic material are not in contact, deterioration of a light-emitting element due to a contaminant such as water can be prevented. The sealing material is formed in a portion of a driver circuit region in the display device, and thus, the narrower frame margin of the display device can also be accomplished.
