Abstract
The present invention relates to method and apparatus of recording graphic data constituting sub-pictures in a main video on a high-density recording medium such as a Blu-ray Disk ROM (BD-ROM) disk. In the present invention, when a plurality of graphic objects, namely, images are received, the plurality of graphic objects and their color control information are organized into a PES (Packetized Elementary Stream) packet and then recorded on a recording medium, wherein the color control information is used in common for screen display by the plurality of graphic objects.
Claims32
A method of recording graphic data on a recording medium, comprising:
- receiving graphic data including a plurality of graphic objects;
- and
- organizing the plurality of graphic objects and color control information into a PES (Packetized Elementary Stream) packet and recording the PES packet on the recording medium, wherein the color control information is used in common for screen display by the plurality of graphic objects so that the graphic objects are changed in color or display effects by using the common color control information.
A computer readable medium having an executable data structure recorded thereon for managing reproduction of images by a reproducing device, comprising:
- a data area storing video and/or audio and graphic data in the form of transport packets, a PES (Packetized Elementary Stream) packet made from some of the transport packets containing the graphic data includes a plurality of graphic objects and color control information that is used in common for screen display by the plurality of graphic objects;
- and
- an information area storing information files for managing reproduction of the video and/or audio and graphic data by the reproducing device so that the graphic objects are changed in color or display effects by using the common color control information.
An apparatus of recording graphic data on a recording medium, comprising:
- a receiving unit configured to receive video and/or audio data, and graphic data including a plurality of graphic objects;
- a packetizer configured to organize the video and/or audio data into a series of PES (Packetized Elementary Stream) packets and to organize the received plurality of graphic objects and color control information into a PES packet, wherein the color control information is used in common for screen display by the plurality of graphic objects;
- and
- a multiplexer configured to multiplex the series of video and/or audio PES packets and the PES packet including graphic objects in the unit of transport packet;
- and
- a driver configured to record the unit of transport packet on a recording medium so that the graphic objects are changed in color or display effects by using the common color control information.
A method of reproducing graphic data on a recording medium, comprising:
- reproducing a PES (Packetized Elementary Stream) packet from the recording medium, the PES packet including a plurality of graphic objects and color information organized into the PES packet, wherein the color information is used in common for screen display by the plurality of graphic objects so that the graphic objects are changed in color or display effects by using the common color control information.
An apparatus for recording graphic data on a recording medium, comprising:
- an optical recording device configured to record data on the recording medium;
- and
- a controller configured to control the optical recording device to record video and/or audio data, and graphic data including a plurality of graphic objects on the recording medium, the video and/or audio data organized into a series of PES (Packetized Elementary Stream) packets and the plurality of graphic objects and color control information organized into a PES packet, wherein
- the color information is used in common for screen display by the plurality of graphic objects, and
- the series of video and/or audio PES packets and the PES packet including graphic objects are multiplexed in the unit of transport packet so that the graphic objects are changed in color or display effects by using the common color control information.
An apparatus for reproducing graphic data on a recording medium, comprising:
- an optical reproducing device configured to reproduce data on the recording medium;
- a controller configured to control the optical reproducing device to reproduce video and/or audio data, and graphic data including a plurality of graphic objects from the recording medium, the video and/or audio data organized into a series of PES (Packetized Elementary Stream) packets and the plurality of graphic objects and color control information organized into a PES packet, wherein
- the color information is used in common for screen display by the plurality of graphic objects, and
- the series of video and/or audio PES packets and the PES packet including graphic objects are multiplexed in the unit of transport packet so that the graphic objects are changed in color or display effects by using the common color control information.
