MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a schematic diagram of attaching information to specific content in the optical disc. As shown in FIG. 1, the optical disc playing device 120 can receive the instantly produced information during the process of playing optical disc 110, it can also receive information stored in the network and information stored in other media, all the information are those attached by the user to a specific scene or a specific segment of the optical disc contents.

Device 120 edits the parameters of the information attached by the user and the corresponding parameters of the specific content on corresponding optical disc into a synchronous playing file, the synchronous playing file can make the attached information and corresponding specific content be played synchronously.

FIG. 2 is a block diagram of an embodiment according to a device 200 for attaching information of the present invention. Device 200 includes an acquiring device 210 for acquiring parameters which include not only the parameters of the information as attached by the user but also the parameters of the specific content of corresponding optical disc, for example, the time parameter, the address parameter, starting time, end time, data type, display effect parameter, etc. of the attached information. These parameters reflect the features like the relative time relation, location relation and relative display relation between the information attached by the user and the specific content of the corresponding optical disc.

Device 200 further includes an editing device 220 for editing the parameters acquired by the acquiring device 210 into a synchronous playing file by the use of a markup language, the adopted markup language is, for example, XML or SMIL, etc.. The synchronous playing file edited by the use of the markup language contains definite relative relations about the playing time and display effect of the corresponding specific content and the information attached by the user. Therefore, the information attached by the user and the specific content of the optical disc can be played synchronously via the synchronous playing file.

In the subsequent playing of the optical disc, the device for playing the optical disc first runs the synchronous playing file and plays the content of the optical disc and the information attached by the user according to the determined time and location relation following the instruction of the file to realize the effect of synchronous playing.

FIG. 3 is a flow chart of an embodiment according to a method for attaching information of the present invention. First, the parameters of the optical disc contents are acquired (step S310). Usually, in order to establish the synchronous relation between the attached information and the specific content of the optical disc, the parameters of the specific content in the optical disc, for example, address parameter, time parameter and so on are required, these parameters can be determined from the parameters of the optical disc contents. In normal case, the parameters of optical disc content are fixed and can be predetermined, for example the time of starting playing of the optical disc content can be set to zero, as a reference for other times.

Then, the parameters of the information attached by the user are acquired (step S320). During playing of the optical disc, the user attaches some information to the specific content of the disc, these information shall have corresponding parameters used for description, for example, an address parameter can describe the address of these information, a time parameter can describe the relative time relation between the time of attaching the information, the playing time and the specific content of the optical disc, and a display parameter can describe the display effect of these information. The above parameters can reflect the time, location and display relations between the information attached by the user and the corresponding specific content and information of the optical disc

Then, the acquired parameters are edited into a synchronous playing file (step S330). The method of editing the parameters into a synchronous playing file can be carried out according to the syntax of the markup language as adopted, the following specific embodiments are provided for further explanation.

After that, it is determined whether other information needs to be synchronously attached to the specific content of corresponding optical disc (stepS340), if so, repeating steps S320 and S330. Prior to attaching a piece of information, if there already exits a synchronous playing file, then corresponding parameters of the optical disc content shall have been edited into the file, whereas the parameters of each segment or scene (i.e. specific content) in the optical disc content can be relatively determined by the corresponding parameter, so it does not need to acquire the parameters of the optical disc content again. However, when first editing and producing the synchronous playing file, it needs to edit the optical disc contents into the synchronous playing file, so it needs to acquire the parameters of the optical disc contents.

The method provided by the present invention does not have limitation on the addresses of the information as attached and the edited synchronous playing file, so long as they can be conveniently invoked during subsequent playing of the optical disc, because in order to realize the synchronous playing effect, it needs to first play the synchronous playing file, and then to invoke the attached information to be played and corresponding optical disc content via the file.

It is very convenient to store the attached information and the synchronous playing file and the content of the optical disc on the same disc, but it may be subject to the limitation of whether the disc is writable and the storage space. It is also very convenient to store the attached information or synchronous playing file in the network, and a plurality of users can share the information via the network, for example, many people can communicate their opinions and comments on a soccer game and an advertising originality and a film cutting together.

The following is a SMIL synchronous playing file formed according to the method for attaching information of the present invention:
