Detailed ways

Please refer to Fig. 1 first, which is a system structure diagram of the present invention.

The digital film that the method of the present invention says below, for convenience of explanation, take the film of digital play as example, in fact, the present invention is not only applied to playing digital film, also can be applied to other similar purposes, for example is to play digital TV program etc. .

The present invention includes two main components, one is a digital video recorder (DVR) 10 and the other is a content provider 12 .

The content provider 12 is used to broadcast the movie to the DVR 10 and to host the movie content discussion board. When there is a new movie, the movie ID generation module 14 will generate a movie ID for the new movie, and then store the new movie in the movie storage module 16 . When a DVR user requests to watch a movie, the movie playing module 18 will call out the selected movie from the movie storage module 16, and broadcast the movie to the DVR 10 in the form of a data stream.

At this time, in the DVR 10 , the recording and playback module 20 can receive the movie data stream from the content provider 12 and output it to be played on the TV 21 .

While playing the movie, the DVR device 10 can receive the pressing command signal of "movie annotation" from the remote controller 22, and after the wireless input module 24 receives the command signal, it transmits the signal to the command interpretation module 26, and the command Interpretation module 26 can identify the type of the command, if it is determined that the command is the command of "movie annotation", DVR device 10 will start the screen display module 28 to divide the screen plane into two parts, one is the movie recording and playback screen, and the other is Annotate frames for movies.

Afterwards, the screen display module 28 will adjust the size of the currently playing movie according to the size of the movie recording and playback screen, and display the movie annotation page on the movie annotation screen.

The screen display module 28 will display the selection list of the content type on the movie annotation screen of the TV. The content type is, for example, "scene picture", "only sound" and "movie clip". At the same time, the command interpretation module 26 will also activate the movie frame marking module 30 to mark the current movie frame as the annotation start frame.

The annotation start frame indicates the frame number when the DVR device 10 receives the "Movie Annotation" command for the first time.

In addition, when the second press signal of "movie annotation" is detected, the movie frame marking module 30 will mark the current frame number as the end frame of the annotation.

The DVR device 10 is then ready to receive a subsequent command from the remote controller to select a content type.

The wireless input module 24 obtains subsequent commands from the remote controller, and the command interpretation module 26 interprets the commands.

In one embodiment, if the command is "picture picture", the picture picture module 31 will activate the picture capture module 32, convert the annotation start picture into a picture in a fixed picture format, and store the picture in the storage module 34 in. Then, the screen display module 28 will display the picture on the movie annotation screen.

In another embodiment, if the command is "sound only", the command interpretation module 26 will start the sound only module 36 to play its audio track, and the sound only module 36 will obtain the annotation start The video track between the screen and the annotation end screen is passed to the sound separation module 38, and the sound is separated from the video track and stored in the storage module 34.

In another embodiment, if the command detected by the command interpretation module 26 is "movie segment", the movie segment module 40 will obtain the movie track between the annotation start frame and the annotation end frame, and store it in the storage Module 34.

After selecting the content, the system will obtain the text information of the user, and the text input module 42 will manage and process the text input by the user. The user can operate the remote controller to output text data to the DVR 10, and the text input device 42 in the DVR 10 will receive such text data.

After content selection and completion of the text message, the DVR device 10 will determine whether it detects a "post" command or a "cancel" command from the remote controller. If the DVR device 10 receives a “post” command, the encoding module 44 encodes the content of the comment and the matching text. The content can be a picture of a scene, or the sound of a movie or a movie clip.

Afterwards, the information posting module 46 will post the annotation information including the annotation content and text on the movie annotation discussion board of the content provider 12 . Wherein, the information is transmitted to the content provider 12 through the network interface module 48 . The information receiving module 49 in the content provider 12 will receive the annotation information from the DVR 10, and the analysis module 50 will analyze and identify the movie that the user will add annotations according to the movie identification, and then the annotation information will be passed to the movie annotation module 52, Controls are stored in the movie storage module 16 .

Please refer to FIG. 2 , which is a flow chart of assigning movie identification to newly added movies.

The content provider 12 assigns a movie ID to each movie newly added to the system storage module 16 . The movie identification is used to allow the content provider 12 to determine the title of the movie that the user wants to annotate, so that the content provider 12 can establish a channel between the annotation information and the appropriate movie name, so that the user can easily Find all annotation information below by typing the movie title.

The process starts at step 200, the content provider 12 judges whether a new movie is added in the storage module 16; The movie generates a movie ID; step 202, after that, the content provider 12 configures a specific storage location for the newly added movie to save the movie annotation information from the user. Therefore, each movie title has a specific storage location for saving annotation information posted by users. The purpose is to facilitate the user to view the annotation information, and the user only needs to search the annotation information according to the movie title.

Please refer to Figure 3 for a flow chart of combining annotation text and content for posting.

The content referred to below may be pictures of movie screens, movie sounds, and movie clips.

The process starts at step 300 , the content provider 12 streams the movie data including the movie ID to the DVR 10 , and the recording and playback module 20 plays the movie. In step 301, the DVR 10 will judge whether it has detected the pressing signal of "movie annotation" from the remote controller 22, wherein when the user operates the remote controller 22 to input the command of "movie annotation", the DVR device 10 will automatically control the The device receives the "Movie Notes" command. In step 302, if the DVR device 10 detects a "movie annotation command", it will proceed to process A, or the DVR device 10 will continue to play the movie.

Please refer to FIG. 3A , which is process A, which shows the flow chart of the system's reaction when the "Movie Annotation" button is pressed.

Step 3020, when the DVR device 10 detects the press signal of "movie comment", the screen marking module 30 will mark the current picture number as the comment start picture according to the "movie comment" press signal; step 3021, then, the screen displays The module 28 will divide the screen into two parts, one is the movie screen, and the other is the movie annotation page screen. After that, in step 3022, the screen display module 28 will adjust the size of the currently playing movie to display it on the movie screen, and at the same time display the movie comment page on the movie comment page screen. The movie comment page screen is a display page for users to input their text comments. Step 3023 , at this time, on the note page, the system will display the content type selection for adding note, such as the scene picture of the movie, only the sound and the movie clip.

"Screen Picture" means to allow users to capture a picture from the movie screen to add annotations. "Leave only sound" means to let the user select the sound from the movie to add to the annotation. "Movie Clip" means that users can select a video track from a movie to add annotations to. All the above can be sent to the movie annotation discussion board of the content provider 12 after adding annotations.

Please refer to FIG. 3 again now. After displaying the content type selection, in step 303, the device 10 is ready to receive the user's command for selecting the content type for posting to the movie annotation discussion board. Then in step 304, the device 10 receives When the user's command is issued, the command will be recognized. In step 305, it is judged whether the command is a "scene picture" command. If so, then in step 306, the procedure B will be entered.

Please refer to FIG. 3B , which is a flow chart of the method for capturing movie screens in the process B in FIG. 3 .

Once the device 10 detects that the user's command is "picture picture", step 3061, it will immediately start the picture capture module to convert the annotation start picture (as described in step 3020 of Figure 3A) into a fixed picture format (step 3060) , and store the fixed picture in the storage module 34, and then, in step 3062, the screen display module 28 will display the converted fixed picture together with the annotation text on the movie annotation page screen.

Please refer to FIG. 3 again. In another embodiment, in step 307, if the device 10 detects that the user's command is not "screen picture", it will compare the command with another example to determine whether the command is " Leave only sound" command. In step 308, if the detected command is the "only keep the voice" command, process C will be performed.

Please refer to FIG. 3C , which is a flow chart of process C in FIG. 3 , a method for obtaining sound from a movie.

Step 3080, the process starts with the device 10 judging whether it has detected the second press signal of "movie annotation", if not, then step 3081, the device 10 continues to play the movie and continuously detects the press signal, step 3082, but if The device 10 detects the pressing signal of the second "movie annotation", and it will immediately start the frame marking module 30 to mark the current frame as the end frame of the annotation on the currently playing movie, and then, in step 3083, the device 10 will Pass the video track between the annotation start screen to the annotation end screen to the sound-only module 36 . Step 3084, the sound separation module 38 will only separate the sound from the video track, step 3085, and store the sound in a sound file format, the sound file format is for example wav, after that, in step 3086, the device 10 will display a representative The image of the wav file is displayed on the movie annotation page screen to show that the sound file will be linked to the annotation text to be input later and included in the annotation information.

Please refer to FIG. 3 again. On the contrary, if the user command detected by the device 10 is neither "picture picture" nor "sound only", step 309, the device 10 will judge whether the command is a "movie clip", if so, Then in step 310 , the device 10 will perform the process D.

Please refer to FIG. 3D , which is a flow chart of the method for capturing movie clips as the process D in FIG. 3 .

Step 3100, the process starts with the device 10 judging whether the second press signal of "movie comment" is detected, and step 3101, if the second press signal of "movie comment" is not detected, the device 10 will continue to play the movie And continue to detect the press signal, but if the device 10 detects the second "movie comment" press signal, step 3102, the device 10 will start the frame marking module 30 to mark the current frame number as the annotation end frame on the currently playing movie , then step 3103, the device 10 will obtain the video track from the annotation start screen to the annotation end screen, step 3104, and store the video track, after that, step 3105, the device 10 will display the image of the video track On the screen of the movie comment page to indicate that it is linked with the added comment text after a period of time, and is included in the comment information.

Please refer to Fig. 3 again, step 311, after the device 10 obtains the content type from the user, it is ready to obtain its annotation text from the user end, therefore, in step 312, the device 10 will continue to detect whether to obtain the annotation from the user end Text, if the device 10 has received the annotation text sent from the user end, then step 313, the device 10 will then judge whether it has detected the information of "posting annotation" from the user end. The “post comment” command will post the comment information including comment text and content to the movie comment discussion board maintained by the content provider 12 . Wherein, if the device 10 detects the user's command of "post annotation", then step 315, the process E will be carried out.

Now please refer to FIG. 3E , which is a flowchart of the method for posting annotation information in the process E in FIG. 3 .

In step 3150, the content provider 12 may require the user to enter a valid user name and password before they can post the annotation information. Once the user name and password are valid, step 3151, the DVR device 10 and the content provider will be established. 12, then, in step 3152, the encoding module 44 will encode the content and annotation text together, after encoding, in step 3153, the device 10 will start the information posting module 46 to pass the annotation text, content and movie identification together Web posting to the movie annotations discussion board. Wherein, as long as the DVR device 10 plays a movie, the movie identification will be sent from the content provider 12 to the DVR device 10 (as shown in step 300 of FIG. 2 ). The purpose of the movie identification is to allow the content provider 12 to determine the title of the movie to be annotated, so the content provider 12 can establish a channel between the annotation information and the appropriate movie title.

As shown in FIG. 3 , in another example, when the device 10 does not detect the command of “post annotation”, but instead receives the command of “cancel” from the remote controller 22, the step of movie annotation will be ended.

See Figure 4, which shows the flowchart for receiving new annotation information in a content provider.

When the annotation information linked with the content and text is sent to the content provider 12, step 400, the information receiving module 49 in the content provider 12 will receive the annotation text, content and movie identification from the DVR device 10, then, step 401 , the analysis module 50 will identify the movie ID and match it with the movie title. According to the movie ID, step 402, the analysis module 50 will establish a channel under the annotation information and the appropriate movie ID/movie name , and then step 403 , the content provider 12 will store the annotation information in the movie storage module 16 . Therefore, all the annotation information of each movie will be stored under its movie ID/movie title (as mentioned in step 202 in FIG. 1 ). For example, all annotation information about the movie "Lord of the Rings" would be saved under the title of the movie "Lord of the Rings".

Please refer to FIG. 5 , which is a flowchart of a method for viewing annotation information in a content provider.

First, in step 500, the connection between the DVR device 10 and the content provider 12 must be established, and then, in step 501, the DVR device 10 will obtain data from the content provider 12, and display the main page of the movie annotation discussion board on the TV screen 21, at this time, step 502, the content provider 12 is ready and enough to obtain the command from the DVR device 10, step 503, it will judge whether the command is "search for annotation information according to the movie title", if so, then step 504, The content provider 12 obtains the movie title from the DVR device 10, step 505, and searches for annotation information according to the movie title. Step 506, the content provider 12 will judge whether it finds the annotation information required by the user, if so, then step 507, the content provider 12 will send the annotation information data selected by the user to the DVR device 10, and once the DVR retrieves the annotation information from the content The provider 12 obtains the data. In step 508 , the screen display module 28 will start to display the annotation information window on the TV screen 21 .

Please refer to FIG. 6 , which is a flowchart of the user interface for composing and posting new annotation information.
