- Fig. 6 illustrates a schematic diagram of an embodiment of an optical disk recording and reproducing apparatus according to the present invention. As shown, an AV encoder 9 receives and encodes audio and video data, subtitle data, or ENAV data.
- the AV encoder 9 outputs the encoded audio and video data along with coding information and stream attribute information.
- a multiplexer 8 multiplexes the encoded audio and video data (or subtitle data, ENAV data) based on the coding information and stream attribute information to create, for example, an MPEG-2 transport stream.
- a source packetizer 7 packetizes the transport packets from the multiplexer 8 into source packets in accordance with the audio/video, subtitle, or ENAV format of the optical disk. As shown in Fig. 6., the operations of the AV encoder 9, the multiplexer 8 and the source packetizer 7 are controlled by a controller 10.
- the controller 10 receives user input on the recording operation, and provides control information to AV encoder 9, multiplexer 8 and the source packetizer 7.
- the controller 10 instructs the AV encoder 9 on the type of encoding to perform, instructs the multiplexer 8 on the transport stream to create, and instructs the source packetizer 7 on the source packet format.
- the controller 10 further controls a drive 3 to record the output from the source packetizer 7 on the optical disk.
- the controller 10 controls the source packetizer 7 to align the audio/video data packets and ENAV data packets in interleaved manner.
- the controller 10 also creates the navigation and management information for managing reproduction of the audio/video data and ENAV data being recorded on the optical disk.
- the controller 10 controls the drive 3 to record the data structure of Figs. 1 to 5 on the optical disk. In the process of reproduction, the controller 10 controls the drive 3 to reproduce this data structure from the optical disk. Based on the information contained therein, as well as user input received over the user interface (e.g., control buttons on the recording and reproducing apparatus or a remote associated with the apparatus) , the controller 10 controls the drive 3 to reproduce the audio/video and ENAV source packets from the optical disk. For example, the user input may specify a playlist or a title to reproduce.
- This user input may be specified, for example, via a menu based graphical user interface preprogrammed into the controller 10.
- the controller 10 controls the sequential reproduction of clip files associated with the specified title or playlist. For example, if a title is chosen, the controller 10 examines management information, e.g., the file 'index.bdmv' for the chosen title, and determines a movie object and/or a web object pertaining to the chosen title.
- a locally-stored clip file on a placed recorded medium or a remotely-stored additional content file pointed by at least one play item included in the playlist is read out or downloaded from a web server. If additional content data is included in the read or downloaded data, the controller 10 controls a demultiplexer 5 and an AV decoder 6 to separate and decode the additional content data accordingly, otherwise, it conducts ordinary reproducing operation of the A/V clip file.
- the reproduced source packets are received by a source depacketizer 4 and converted into a data stream (e.g., an MPEG-2 transport packet stream) .
- the demultiplexer 5 demultiplexes the data stream into encoded video and audio, ENAV, and/or subtitle data.
- the AV decoder 6 decodes the encoded data to produce the original audio and video, ENAV, and/or subtitle data that was fed to the AV encoder 9.
- the controller 10 controls the operation of the source depacketizer 4, demultiplexer 5 and AV decoder 6.
- the controller 10 receives user input on the reproducing operation, and provides control information to AV decoder 6, demultiplexer 5 and the source packetizer 4.
- the controller 10 instructs the AV decoder 9 on the type of decoding to perform, instructs the demultiplexer 5 on the transport stream to demultiplex, and instructs the source depacketizer 4 on the source packet format .
- the AV decoder 6 interprets the ENAV data, instead of decoding, to conduct interpreted operations with the aid of the controller 10. While Fig. 6 has been described as a recording and reproducing apparatus, it will be understood that only a recording or only a reproducing apparatus may be provided using those portions of Fig. 6 providing the recording or reproducing function.
- the present invention provides a greater level of flexibility in simultaneous reproduction of audio/video data and additional content data and in additional content providing ways than previously available. While the invention has been disclosed with respect to a limited number of embodiments, those skilled in the art, having the benefit of this disclosure, will appreciate numerous modifications and variations there from. For example, while described with respect to a Blu-ray ROM optical disk in several instances, the present invention is not limited to this standard of optical disk or to optical disks. It is intended that all such modifications and variations fall within the spirit and scope of the invention.
