Method of video information transmission, as well as an information carrier, a device for receiving and a device for transmitting video information

A non-transitory information carrier on which an information signal is recorded which information signal represents video information for reproduction on a display of a receiver device,

• the video information being a multiplexed MPEG stream,
• the video information comprises basic information and overlay information related to the basic information,
• the basic information being an elementary stream of encoded video data,
• the overlay information comprises at least one overlay page to be displayed as a unit in combination with the basic information,
• the overlay page being encoded as a private stream,
• wherein the overlay information additionally comprises:
• a presentation timestamp which denotes an initial presentation time of the overlay information, and
• time information for controlling a period of time during which the overlay formation is to be displayed,
• the time information being expressed in units of an MPEG system clock.

A receiver device for receiving video information for reproduction on a display via an information signal that represents the video information,

• the video information being a multiplexed MPEG stream,
• the video information comprising basic information and overlay information related to the basic information,
• the basic information being an elementary stream of encoded video data,
• which overlay information comprises at least one overlay page to be displayed as a unit in combination with the basic information,
• the overlay page being encoded as a private stream,
• wherein the overlay information additionally comprises:
• a presentation timestamp which denotes an initial presentation time of the overlay information, and
• time information for controlling a period of time during which the overlay information is to be displayed,
• the time information being expressed in units of an available MPEG system clock of the receiver device.
• which receiver device comprises;
• means for receiving the information signal, and
• combining means for generating a video signal for displaying the basic information combined with the overlay information,
• means for recovering the time information from the information signal and wherein the combining means are arranged for controlling the displaying of the overlay information as a function of the time information.

A transmitter device for transmitting video information to a receiver device for reproduction on a display,

• the video information being a multiplexed MPEG stream,
• the video information comprising basic information and overlay information related to the basic information,
• the basic information being an elementary stream of encoded video data,
• the overlay information comprises at least one overlay page to be displayed as a unit in combination with the basic information,
• the overlay page being encoded as a private stream,
• wherein the overlay information additionally comprises:
• a presentation timestamp which denotes an initial presentation time of the overlay information, and
• time information for controlling a period of time during which the overlay information is to be displayed,
• the time information being expressed in units of an MPEG system clock of the receiver device,
• which transmitter device comprises:
• generator means for generating the information signal,
• means for transmitting a complete information signal, and
• means for generating the time information and the generator means are arranged for adding the time information to the overlay information to form the complete information signal.
