To further illustrate, the aforementioned first popularity indexes are defined as rebroadcast positive index values.

Therefore, the hotspot detection module 23 adds the first heat index at each time point (that is, the 0th second, the 5th second and the 10th second) to obtain the first time-sharing interval CH1#Seg1 (range A). The interval heat index is 8, and after the hotspot detection module 23 confirms that the interval heat index (8) is greater than a interval threshold value (such as 5), the hotspot detection module 23 uses the hotspot selection method (2) to find out the first point The median of the time points (that is, when the playback starts) of the eight playback records in the time interval CH1#Seg1 (range A), for example: [0, 0, 5, 5, 5, 5, 5, The median in 10] is (i.e. 5), and then the hotspot detection module 23 utilizes the hotspot selection method (3) according to the time point (the 5th second) corresponding to the median to obtain The first hot spot in the first time-sharing interval CH1#Seg1 (range A) is 10:00:05, and the first heat index (i.e. 5) of the first hot spot (5th second) is the first hot spot heat index .

Next, the hotspot detection module 23 takes the first hotspot (10:00:05) in the first time-division interval CH1#Seg1 (range A) as the starting time of the first hotspot. Again, the hotspot detection module 23 utilizes the hotspot selection mode (2), (3) according to the eight pens in the first time-sharing interval CH1#Seg1 (range A) when looking back and playing the record, for example: [ 14, 14, 14, 29, 29, 29, 29, 29] to find the time point (10:00: 29), and this time point is used as the end time of the first popular segment. Afterwards, the hot spot detection module 23 will base on the first hot spot (10:00:05), the first hot segment (10:00:05~10:00:29) of the first time-sharing interval CH1#Seg1 (range A). ), the first hotspot popularity index (5) and the first interval popularity index (8) generate the hot segment information with the first hot spot, and then provide the hot segment information with the first hot spot to the user through the channel streaming module 24 End devices D1~D10.

The following embodiment is the second embodiment of the hot segment real-time detection system of the live channel of the present invention, and the main content of the second embodiment is as follows, and the rest of the content is the same as the description of the above-mentioned FIG. 1 and the first embodiment.

In this embodiment, the user-end devices D91~D100 (i.e., the user-end device 10 in FIG. 1 ) receive the hot segment information with hotspots transmitted by the platform-side device 20 (such as the hotspots with the first hotspot in the first embodiment) segment information), watch the hotspot play record generated by the popular segment with hotspots by multiple users, as shown in FIG. 3 , and the hotspot play record is stored in the storage module 22. For example: the playback record of the client device D92 is <D92, CH1#Seg1, IndexType2, 10:00:05, 10:00:09>.

In one embodiment, the platform device 20 can calculate the start and end times of popular segments based on the hotspot detection module 23, and provide users with only one video generated based on the start and end times of the hot segments (for example, only the one shown in FIG. 3 is provided. range B), or the platform device 20 is marked on the original live channel according to the start and end of the hot segment, so that the user continues to watch the follow-up content after watching the hot segment (such as providing the user to continue watching the range B of FIG. 3 future video).

It must be explained first that in this embodiment, it is assumed that the platform device 20 only provides the hot clips from 10:00:05~10:00:29 to the user devices D91~D100, so the user devices D91, D93~D97, D100 The end time of the hot spot broadcast in the hot spot broadcast record is 10:00:29.

Accordingly, the hotspot detection module 23 obtains the hotspot playback records of the client devices D91~D100 from the storage module 22, wherein the hotspot detection module 23 determines the hotspot playback records of the client devices D91, D93~D97, and D100 The playback length is greater than an index threshold (such as 5), so the hotspot detection module 23 will use the hotspot playback records of the end devices D91, D93~D97, and D100 as hotspot positive indicators and the weight is preset to 1, and the hotspot The heat value of the playback record is 1, and the hotspot detection module 23 judges that the playback length in the hotspot playback records of the user-side devices D92, D98, and D99 is less than an index threshold (such as 5), so the hotspot detection module 23 will The hotspot playback records of the client devices D92, D98, and D99 are used as hotspot negative indicators with a default weight of -1, and the popularity value of the hotspot playback records is 1.

Then, the hotspot detection module 23 calculates the 5th second in the hotspot playback records of the user-end devices D91, D93~D97, D100 based on the weights and popularity values of the above ten hotspot play records and using the popularity index calculation formula (1). The popularity index is 7, and it is defined as the hotspot positive index value. In addition, the heat index of the 5th second in the hotspot play records of the user-end devices D92, D98, and D99 is calculated as -3, and it is defined as the hotspot negative index value. And by hotspot detection module 23 will hotspot The positive index value (ie 7) is added to the hotspot negative index value (ie -3) to obtain the second heat index of 5 seconds as 4, which is also defined as the hotspot positive index value. Afterwards, the hotspot detection module 23 will accumulate the second heat index (that is, 4) in the 5th second calculated according to the hotspot play records back to the first heat index (that is, 5) in the 5th second of the first embodiment to be updated The heat index of the next 5 seconds (i.e. 9).

The hotspot detection module 23 utilizes the hotspot selection method (2) again and finds out when the playback of the eight playback records of the first embodiment starts and the playback of the ten hotspot records of this embodiment ends. The median of the first time-division interval CH1#Seg1 (range A) is 5, and then the hotspot detection module 23 utilizes the hotspot selection method (3) according to the time point (the 5th second) corresponding to the median, To get the second hot spot of the first time-sharing interval CH1#Seg1 (range A) as the 5th second, and the heat index (i.e. 9) of the second hot spot (the 5th second) is used as the second hot spot heat index, and the second hot spot heat index The popularity index of two intervals (namely 12), whereby the hot segment information with the first hot spot is updated by the hot spot detection module 23 to generate the hot segment information with the second hot spot.

Therefore, through the hotspot playback records generated by users watching hotspots and popular clips, the hotspot positive index value and the hotspot negative index value are calculated, so that the platform device 20 can calculate the hotspot positive index value and the hotspot negative index value in real time. The negative index value of hotspots is used to update the information of popular clips with hotspots, so as to dynamically adjust hotspots and popular clips, and then provide users with hotspots and popular clips that are closer to their preferences in an accurate and real-time manner.

The following embodiment is the third embodiment of the hot segment real-time detection system of the live channel of the present invention, and the main content of this third embodiment is as follows, and the rest of the content is the same as above-mentioned Figure 1, the first embodiment and the second embodiment Example description.

In this embodiment, the hotspot detection module 23 further performs hotspot detection in an iterative hotspot detection manner. Specifically, the hotspot detection module 23 will determine the temperature of each hotspot in a time interval The calculation results of the index and the interval popularity index are accumulated instead of calculating all the obtained interactive records (review playback records or hotspot playback records), and only need to calculate the newly received interaction record data and add them to the front One-time calculation results to improve the efficiency of hotspot detection and achieve the purpose of real-time detection.

Specifically, the hotspot detection module 23 performs hotspot detection for the first time-sharing interval CH1#Seg1 (range A) from 10:00:00 to 10:00:29, and then performs hotspot detection again every 30 seconds. until the end of the live broadcast or within a period of time after the end of the live broadcast, wherein, as shown in Figure 2, the hotspot detection module 23 calculates the first The first hotspot popularity index, the first interval popularity index, the first hotspot and the first hot segment in the time-sharing interval CH1#Seg1 (range A) (as shown in FIG. 4 ).

Also, the hotspot detection module 23 also calculates the number of times accumulated when each replay of the user-end device D6 is finished, for example: the 34th second is accumulated once, and is defined as the forward index value of the replay, and is added back to the original replay The broadcast forward indicator (when the broadcast is finished), as shown in Table T4 of FIG. 4 . In addition, since the playback start time of the user-end device D4 is not 10:00:05 (the first hot spot), the end-time of the playback of the user-end device D4 will not be included in the calculation of the end time of the popular segment.

On the other hand, as described in the above-mentioned second embodiment, the hotspot detection module 23 sets the heat index of the 5th second in the hotspot play record of the user-end devices D92, D98, and D99 as -3, and defines it as a negative hotspot indicator value, and the popularity index in the 5th second of the hotspot play records of the user-end devices D91, D93~D97, D100 is 7, which is defined as the hotspot positive index value. Therefore, the hotspot detection module 23 accumulates the playback positive index value, the hotspot positive index value and the hotspot negative index value at each time point to renew the heat index at the time point, as shown in Table T3 of FIG. 4 Show.

Furthermore, the hotspot detection module 23 uses the median of the popularity index at all time points as the third hotspot (such as 10:00:05) and the start time of the third hotspot segment, and the popularity index of the third hotspot is more As the third hot spot heat index (ie 10), the hot spot detection module 23 accumulates the heat index at each time point as the third interval heat index (ie 14).

In addition, because the playback length of the hotspot playback records of the user-end devices D91, D93~D97, and D100 is greater than the index threshold (such as 5), the hotspot detection module 23 calculates the hotspots of the user-end devices D91, D93~D97, and D100 The accumulated number of times when the playback is over, and it is defined as the positive index value of the hotspot (when the playback is over), for example, the 34th second is accumulated six times, and the 19th second is accumulated once. after, The hotspot detection module 23 finds the median (i.e. 34) The corresponding time point (10:00:34), take this time point (10:00:34) as the end time of the hot clip, so the updated third hot clip is 10:00: 05~10:00:34.

Finally, the hotspot detection module 23 is based on the third hotspot (10:00:05), the third hotspot segment (10:00:05~10:00:34), the third hotspot heat index (10) and the third interval The popularity index (14) generates the hot segment information with the third hot spot, and then provides the hot segment information with the third hot spot to the user-end devices D1~D10, D91~D100 through the channel streaming module 24.
