As shown in FIG. 2, the following describes a flow of a method for switching a panoramic image by using a switching system S for playing a panoramic image, which includes at least the following steps:

Step S201: providing a real-time video source 10, including a first continuous live play image 1010, a second continuous live play image 1020, and at least one captured from the first continuous live play image 1010 and compressed. A segment of the instant play buffer image 1030 and the instant play buffer image 1040 of the at least one second segment captured from the second consecutive live play image 1020.

Step S202: The first continuous play image 1010 is received and played by the first play mode 3010 of the play module 30.

Step S203: The first switching instruction is received, so that the playing module 30 is switched from the first playing mode 3010 to the second playing mode 3020, and the first delay time segment in which the second consecutive instant playing image 1020 cannot be played immediately is generated. After the first play mode 3010 is switched to the second play mode 3020, the second play mode 3020 of the play module 30 first plays the at least one second clip of the instant play buffer image 1040 to fill the first delay period, and then continues to play. Two consecutive instant play images 1020.

Step S204: The second switching instruction is received, so that the playing module 30 is switched from the second playing mode 3020 to the first playing mode 3010, and a second delay time segment in which the first continuous instant playing image 1010 cannot be played immediately is generated. After the second play mode 3020 is switched to the first play mode 3010, the first play mode 3010 of the play module 30 first plays the at least one first clip of the instant play buffer image 1030 to fill the second delay period, and then continues to play the first play mode 3010. A continuous instant play image 1010.

In detail, first, it can be provided by the switching system S that plays the panoramic image. Instant video source 10. The instant video source 10 can include any instant video provided through a network streaming platform, or through a video file input from an external storage medium.

In addition, the first continuous live play image 1010 is captured and compressed to obtain at least one first clip of the instant play buffer image 1030. Similarly, the second continuous live play image 1020 is extracted and compressed. In order to obtain at least one second segment of the instant play buffer image 1040.

In addition, the switching system S for playing the panoramic image transmits the instant video source 10 through the storage module 20, that is, the first continuous instant playing image 1010, the second continuous instant playing image 1020, and the at least one first segment of the instant playing. The buffered image 1030 and the at least one second segment of the instant play buffer image 1040 are temporarily stored in the temporary storage area 210.

Next, the playback module 30 of the switching system S that plays the panoramic video receives the playback command from the outside and starts playing the video. The play module 30 of the switching system S for playing panoramic images of the present invention provides a first play mode 3010 and a second play mode 3020.

In detail, after receiving the play command from the outside, in the first play mode 3010 of the play module 30, the play module 30 accepts and plays the first continuous live play image 1010. At this time, the second play mode 3020 of the play module 30 can play the at least one second clip of the instant play buffer image 1040 in advance, or play simultaneously with the period of the first play mode 3010. In other words, when the first play mode 3010 continues, the second play mode 3020 can also continue to play the at least one second clip of the instant play buffer image 1040. As usual, when the playback module 30 receives the first switching command and wants to switch from the first playback mode 3010 to the second playback mode 3020, a first delay period in which the second consecutive live playback video 1020 cannot be played immediately will be generated. . However, since the playing module 30 of the switching system S for playing the panoramic image of the present invention has previously made the second playing mode during the playing of the first playing mode 3010. The 3020 first plays the at least one second segment of the instant play buffer image 1040 such that the first delay period can be filled by the at least one second segment of the instant play buffer image 1040. Moreover, after the play module 30 switches from the first play mode 3010 to the second play mode 3020 through the first switching instruction, since the first delay period has been filled by the at least one second segment of the instant play buffer image 1040, The second continuous live play image 1020 is continuously played. In short, the second play mode 3020 is played during the playing of the first play mode 3010 to play the at least one second play instant play buffer image 1040 to fill the first delay time segment, so that the first continuous live play image 1010 Switching between the second consecutive live play image 1020 does not cause a delay.

As described above, the playing module 30 of the switching system S that plays the panoramic image at this time provides the second playing mode 3020 and plays two consecutive instant playing images 1020. At this time, the playing module 30 of the switching system S that plays the panoramic image further receives a second switching instruction to switch the playing module 30 from the second playing mode 3020 to the first playing mode 3010. Similarly, when the second play mode 3020 is to be switched to the first play mode 3010, a second delay period in which the first consecutive live play image 1010 cannot be played immediately is also generated. As described above, since the playing module 30 of the switching system S for playing the panoramic image is in the second playing mode 3020, the first playing mode 3010 has played the at least one first segment of the instant playing buffer image 1030 at the same time or in advance. Therefore, the instant play buffer image 1030 of the at least one first segment is used to fill the second delay period, so that the play module 30 can continuously play the first continuous live play image 1010. As a result, the switching between the first continuous live play image 1010 and the second continuous live play image 1020 does not cause a delay.

It is to be noted that the first continuous live play image 1010 of the present invention may be one of a continuous 2D live play image and a continuous 3D live play image, and the second continuous live play image 1020 may also be The other is a continuous 2D live play image and a continuous 3D live play image. In other words, the switching system S for playing panoramic images of the present invention can be applied to play continuous Switching between 2D live play images and continuous 3D live play images.

Please refer to FIG. 3 and FIG. 4. FIG. 3 is a flowchart of an embodiment of the present invention; FIG. 4 is a timing diagram of a method for switching a panoramic image according to the present invention. In the following, the switching system and the switching method for playing the panoramic image of the present invention will be described in detail through the implementation of the continuous 2D instant playing image and the continuous 3D instant playing image. A flow of an embodiment of the method for switching a panoramic image of the present invention includes at least the following steps: Step S301: providing a real-time video source 10 having a first continuous live play image 1010 and a second continuous live play image 1020.

Step S302: The first continuous live play image 1010 and the second consecutive live play image 1020 are temporarily stored in the temporary storage area 210 of the storage module 20.

Step S303: During the playing period, the first continuous live playing image 1010 temporarily stored in the temporary storage area 210 is played by using the playing module 30, wherein the playing module 30 accepts and compresses every predetermined time period during the playing period. The second continuous instant playback of the image of the predetermined length of the image 1020 to form an instant play buffer image of the segment.

Step S304: According to the switching instruction, the playing module 30 switches from playing the first consecutive instant playing image 1010 to the instant playing buffer image of the playing segment.

Step S305: After the playback of the instant play buffer image of the segment ends, the second continuous live play image 1020 continues to play the instant play buffer image of the segment.

The following is a detailed example of a continuous 2D instant play image and a continuous 3D live play image.

First, an instant video source 10 is provided in the switching system S that plays the panoramic image. The instant video source 10 is a continuous 2D live play image and a continuous 3D live play image. The continuous 2D live play image and the continuous 3D live play image are temporarily stored in the temporary storage area 210 of the storage module 20 by the storage module 20 in the switching system S for playing the panoramic image.

Referring to FIG. 4 at the same time, the following is an example of switching from a continuous 2D instant play image to a continuous 3D live play image. When switching the panoramic image switching system S Upon receiving a 2D video playback command from an external (eg, user), the system plays a continuous 2D live playback image temporarily stored in the temporary storage area 210 through the playback module 30. The playback module 30 accepts and compresses the continuous 3D live playback image every predetermined period of time during the playback of the internal video program of the switching system S for playing the panoramic image during the playback of the continuous 2D live playback image by the playback module 30. A predetermined length of image to form a 3D live play buffer image of the clip. The predetermined time may be 1 to 10 seconds, and the predetermined length image may be 2 to 5 seconds. In other words, when the playback module 30 is playing a continuous 2D live play image, the playback module 30 accepts and compresses the unplayed continuous 3D live play image by about 2 to 5 every 1 to 10 seconds. The length of the movie in seconds, so that the length of the movie can form a 3D live play buffer image of the clip. Therefore, when the play module 30 plays a continuous 2D live play image, the 3D instant play buffer image of the compressed continuous 3D live play image segment of the predetermined length image is simultaneously at each time point. It is worth noting that the predetermined time period and the time of the predetermined length of image can be adjusted according to actual needs. In the present embodiment, the preferred predetermined time period is 1 second, and the predetermined length image is 3 seconds, but is not limited thereto. That is to say, in the embodiment, when the playing module 30 is playing a continuous 2D instant playing image, the playing module 30 accepts and compresses the unplayed continuous 3D live playing image every 1 second. A predetermined movie length of 3 seconds, such that the predetermined movie length can form a 3D live play buffer image of the clip. As can be seen from FIG. 4, on the playing time axis of the instant video source 10, when consecutive 2D live playing images are played, the time point of each second has a starting time from the number of seconds and a length of 3 A 3D instant play buffered image of a segment of seconds.

As described above, the switching system S for playing the panoramic image is further switched from playing the continuous 2D live playing image to the 3D instant playing buffer image of the segment according to the switching instruction. Since the playback module 30 already contains the continuous 2D live play image being played and the 3D instant play buffer image of the pre-buffered clip in 3 seconds at each second time, when the switch command is issued from the outside, the play is played. The module 30 switches from the continuous 2D instant play image to the 3D instant play buffer image of the segment of the continuous 3D instant play image, and waits for the 3D instant play buffer image of the clip to end after playing, and immediately continues to play the original uncompressed continuous image. 3D instant play image. As shown in FIG. 4, it is assumed that when the switching instruction is issued at t=t 4 , the play module 30 plays the 3D instant play buffer image of the clip buffered from t=t 4 at t=t 5 , and then after t=t At 7 o'clock, continuous 3D live playback images are played.

On the other hand, the switching mode for switching from a continuous 3D live play image to a continuous 2D live play image is also the same. In detail, first, when the switching system S that plays the panoramic image receives a 3D video playback command from the user, the system plays the continuous 3D live playing image temporarily stored in the temporary storage area 210 through the playing module 30. During the playing of the continuous 3D live playing image by the playing module 30, the playing module 30 accepts and compresses one of the consecutive 2D instant playing images every predetermined period of time by playing the internal software program of the switching system S for playing the panoramic image. A predetermined length of image to form a 2D live play buffer image of the clip. Similarly, the predetermined time period is 1 second, and the predetermined length image is 3 seconds. That is to say, in the embodiment, when the playing module 30 is playing a continuous 3D instant playing image, the playing module 30 accepts and compresses the unplayed continuous 2D live playing image every 1 second. A movie segment having a predetermined movie length starting from the second of 3 seconds to form a 2D live play buffer image of the segment. In this way, on the time axis of playing the instant video source 10, when consecutive 3D instant play images are played, the time of each second has a 2D instant play of the clip starting from the number of seconds and having a length of 3 seconds. Buffer images.

As described above, the switching system S for playing the panoramic image is further switched from the continuous 3D live playing image to the 2D instant playing buffer image of the clip according to the switching instruction. Since at each second time, the play module 30 already contains the continuous 3D live play image being played and the 2D instant play buffer image of the pre-buffered clip in 3 seconds. Therefore, when the switching instruction is issued from the outside, the playing module 30 switches from the continuous 3D instant playing image to the 2D instant playing buffer image of the clip, and waits for the 2D instant playing buffer image of the clip to end after playing. Continue to play a continuous 2D live playback image that was originally uncompressed. Thereby, the switching between the continuous 2D instant play image without delay and the continuous 3D live play image is completed.

It is worth mentioning that the playing module 30 of the switching system S for playing panoramic images of the present invention may be a video platform that is streamed through a wired or wireless network. When the playing module 30 is a video platform that is streamed through the network, the playing module 30 receives the first continuous instant playing image 1010 and the second continuous instant playing image 1020 from the instant video source 10 through the network. The playback module 30 needs to accept and compress the predetermined length of the second consecutive instant play image 1020 to form the instant play buffer image of the clip while playing the first continuous live play image 1010, in order to reduce the transmission of the audio and video data through the network. The occupied bandwidth, the clip's instant play buffer image can have a smaller resolution. And vice versa, when the playing module 30 plays the second consecutive instant playing image 1020, and needs to accept and compress the predetermined length image of the first continuous instant playing image 1010 to form a short-playing video buffer of the clip, the clip Instant playback of buffered images can have less resolution. Moreover, the resolution of the instant play buffer image of the clip is less than the resolution of the instant video source 10.

In summary, the present invention provides a switching system S and a switching method for playing a panoramic image, which can pass the first playing mode 3010 of the playing module 30 to receive and play the first continuous. The instant playback image 1010", "the playback module 30 receives the first switching command to switch from the first playback mode 3010 to the second playback mode 3020, and generates a first delay period in which the second consecutive live playback video 1020 cannot be played immediately. And the technical feature of the second playback mode 3020 of the playback module 30 playing the at least one second-segment instant play buffer image 1040 to fill the first delayed delay segment and then playing the second continuous live playback image 1020. The delay period generated when switching between the first continuous live play image 1010 and the second continuous live play image 1020 can be filled. Thereby, the viewer does not perceive the delay between the first continuous live play image 1010 and the second continuous live play image 1020, thereby improving the viewing quality.

Another advantageous effect of the present invention is that the switching system S and the switching method for playing a panoramic image provided by the present invention can be used to play the first continuous temporary storage area 210 by using the playing module 30 during the playing period. The instant play image 1010", "during the playback period, the playback module accepts and compresses the predetermined length of the second consecutive live play image 1020 to form the instant play buffer image of the clip" and "switch according to the switch.
