Method and device for basic and overlay video information transmission

A transmitting system comprising:

• means for acquiring basic information including video content capable of being displayed on a display device;
• means for acquiring overlay information includes overlay content capable of being displayed on a display device and time information;
• combining means for combining said basic information and said overlay information to form an information signal;
• and
• transmitting means for transmitting said information signal to a receiving system,
• wherein, in the receiving system, the overlay content is overlaid on a portion of the displayed video content for a period of time during the displaying of the video content,
• wherein the overlay content, and not the portion of the displayed video content, appears visible during the period of time, and
• wherein the time information is indicative of the period of time.

A receiving system, comprising receiving means for receiving an information signal transmitted from a transmitting system,

• wherein the information signal comprises basic information and overlay information,
• wherein the basic information includes video content capable of being displayed on a display device,
• wherein the overlay information includes overlay content and time information,
• wherein the overlay content in the information signal is capable of being displayed on a display device, said overlay content being overlaid on a portion of the displayed video content for a period of time during the displaying of the video content,
• wherein the overlay content, and not the portion of the displayed video content, appears visible during the period of time, and
• wherein the time information is indicative of the period of time.

An information carrier, comprising a substrate and an information signal recorded on the substrate,

• wherein the information signal comprises basic information and overlay information,
• wherein the basic information includes video content capable of being displayed on a display device,
• wherein the overlay information includes overlay content and time information,
• wherein the overlay content in the information signal is capable of being displayed on a display device, said overlay content being overlaid on a portion of the displayed video content for a period of time during the displaying of the video content,
• wherein the overlay content, and not the portion of the displayed video content, appears visible during the period of time, and
• wherein the time information is indicative of the period of time.
