The above and other aspects of the invention will become better understood with regard to the following detailed description of the preferred but non-limiting embodiment(s). The following description is made with reference to the accompanying drawings.
The video related tag generating apparatus 20 includes a synchronous information generator 210, an object position generator 220, an object information generator 230 and a video related tag generator 240. The video related tag generating method may be applied to the generating apparatus 20 and includes the following steps. First, as shown in step 110, the synchronous information generator 210 generates synchronous information S3 according to the target object 32. The synchronous information S3 is, for example, a time stamp or a frame number. The object position generator 220 generates an object position S4 according to the target object 32. The object position S4 indicates the position where the target object 32 is located in the video frame 31. The object information generator 230 generates object information S5 according to the target object 32. The object information S5 includes, for example, the description associated with the target object 32, or is used for linking to at least one of an electronic commerce portal website, a website associated with the target object 32, information associated with the target object 32 and an advertisement. The description associated with the target object 32 may relate to, for example, the brand, price or location of sale of the target object. After the information link associated with the target object 32 is clicked and selected, the user can further watch the highlights or background stories of the video broadcast program S1 via a network interface 512.
Next, as shown in step 120, the video related tag generator 240 generates the video related tag S2 according to the synchronous information S3, the object position S4 and the object information S5. The generating apparatus 20 is disposed in, for example, a remote server, and the video related tag S2 is packaged into network packets, for example. The generating apparatus 20 can transfer the video related tag S2 to a client or clients via the network.
The video interacting apparatus can be applied to the video interacting system 50 and includes the following steps. First, as shown in step 410, the video interacting apparatus 51 receives the video broadcast program S1 via the video signal receiver 511, and receives the video related tag S2 via the network interface 512. The video related tag S2 is generated by the generating apparatus 20, for example, and transferred to the network interface 512 via the network. The video broadcast program S1 received by the video signal receiver 511 includes the video frame 31 having the target object 32, and the video related tag S2 received by the network interface 512 relates to the target object 32.
Next, as shown in step 420, the video related tag processing unit 513 generates the synchronous information S3, the object position S4 and the object information S5 according to the video related tag S2. Then, as shown in step 430, the triggering region generating unit 514 generates a triggering region 33 according to an object position S5. The triggering region 33 may be displayed or hidden. The triggering region 33 could be displayed in different way. The triggering region 33 could be displayed a dashed frame such as
Next, as shown in step 440, the image synchronizing unit 516 synchronously overlaps the triggering region 33 on the video frame 31 according to the synchronous information S3 when the video frame 31 is displayed by the display 60. Finally, as shown in step 450, the user uses the triggering apparatus 52 to generate a key-press signal S6, and the video related tag processing unit 513 receives the key-press signal S6 to select the triggering region 33, such that the image synchronizing unit 516 overlaps the object information S5 on the video frame 31, and outputs to display 60 via the outputting unit 517.
The triggering region 33 and the object information S5 could be flexibly adjusted according to a resolution of the display 60. For example, the original resolution of the video related tag S2 is set to 320×240, but the resolution of the display 60 is 640×480. The triggering region 33 and the object information S5 could be flexibly adjusted 640×480 to match the resolution of the display 60.
In addition, in order to remind the user that the object information S5 is hidden in the video frame 31, the video related tag processing unit 513 can further output a notification signal S7 to the processor 522 of the triggering apparatus 52 according to the video related tag S2. The triggering apparatus 52 generates an indication signal, which indicates that the triggering region 33 is located on the video frame 31, according to the notification signal. The indication signal is, for example, an audible signal, a vibration signal or a lighting signal.
With the video related tag generating apparatus, the video related tag generating method, the video interacting method, the video interacting system and the video interacting apparatus, the user can not only watch the video broadcast program in a non-monotonic manner but also interact with the contents of the video broadcast program.
