Description

  The present invention relates to a distribution method optimization apparatus, system, method, and program for distributing content.

Conventionally, a content distributor may select an efficient distribution method based on the number of terminals when distributing content to a user's terminal.

FIG. 9 is a diagram showing a first example of the optimization information determination method according to the present embodiment.
In this example, the number of users using the content is used as a determination criterion, and a distribution method with a high evaluation is preferentially assigned to content with a large number of users.

  Here, when the evaluation of the distribution method is “broadcast> IP live streaming (high image quality)> IP live streaming (low image quality)”, the distribution device 20 distributes the contents A, B, and C. To do.

  First, based on the received information, the number of users is calculated as “content A> content B> content C”. At this time, the optimization information generating unit 54 correlates the distribution priority of each content with the number of users, and as shown in FIG. 9A, the content A is broadcast and the content B is IP live streaming (high image quality). Then, optimization information is generated so that the content C is distributed by IP live streaming (low image quality).

  Thereafter, the number of users is changed as “content C> content A> content B”. Then, the optimization information generation unit 54 broadcasts the content C, IP live streaming (high quality) the content A, and IP live the content B according to the change in the number of users, as shown in FIG. 9B. Generate optimization information to deliver in streaming (low quality).

  Furthermore, distribution of content D having a large number of users is newly started. Then, the optimization information generation unit 54 broadcasts the content D, the content C by IP live streaming (high image quality), and the contents A and B according to the change in the number of users as shown in FIG. Optimized information is generated to be distributed by IP live streaming (low image quality).

  In this example, the optimization information is generated based on the number of users in real time. However, the present invention is not limited to this, and the optimization information generation unit 54 may change the number of users or the number of users including the number of reservations. A ratio or the like may be used, or a tendency indicating interest in the content may be obtained from an access history to related information and ranked.

FIG. 10 is a diagram illustrating a second example of the optimization information determination method according to the present embodiment.
In this example, the distribution method is assigned by points based on the total resolution of the distributed content.

  Contents A, B, and C are distributed by full segment broadcasting, IP live streaming (high image quality), and IP live streaming (low image quality). Here, full-segment broadcasting is limited to one wave, and IP live streaming (high image quality) is limited to two streams.

  Based on the user information, the number of users for each type of the receiving device 30 that receives the contents A, B, and C (TV, smartphone, etc.) is aggregated for each content. For each combination of distribution methods that can be assigned, the resolution × the number of users is totaled as a point. For example, in the example of FIG. 10, pattern 1 that is the maximum point is adopted as the optimization information.

  For example, when the number of users is aggregated at regular intervals, distribution method allocation dynamically changes in accordance with the calculated points even while content is being distributed.

  Note that the optimization information generation unit 54 is estimated based on, for example, resolution per user, a determination criterion using an average value or median delay time, or an index such as average viewing time in addition to the total resolution. Optimization information may be generated by evaluating a distribution method allocation pattern according to a determination criterion using the degree of concentration or eagerness to view content by a user.

  So far, the function of generating optimization information by the distribution method optimizing device 50 has been described. However, based on the distribution method list with priority set based on the optimization information, the receiving device 30 The content acquisition method can be determined according to the determination criteria.

For example, the receiving device 30 may prioritize a distribution method with high resolution or a distribution method with stable communication quality among available distribution methods.
In addition, for example, in the case of stormy weather, select online distribution rather than broadcasting such as BS, select another broadcasting or communication if it is located near the outer edge of the broadcasting area or wireless communication area, and select broadcasting rather than communication while traveling by train etc. For example, the receiving device 30 can determine a more stable acquisition method.
Further, for example, depending on the display resolution and the reception rate of the reception device 30, an efficient and stable reception method may be selected by suppressing the communication rate more than the high-definition distribution method more than necessary.
Furthermore, for example, when there is a difference in the charge amount depending on the type of communication network (WiFi, mobile network, etc.), communication with lower cost may be selected.

According to the present embodiment, the distribution method optimizing device 50 generates optimization information in which a distribution method is assigned to each of a plurality of contents according to a determination criterion based on received information. Thereby, the distribution system 1 is assigned an efficient distribution method to a plurality of contents to be distributed.
Therefore, the distribution method optimizing apparatus 50, for example, is an inefficient use state of a radio wave band in which few users receive efficient broadcast waves while many users use specific content in a network stream. Can be improved.

  Also, in the distribution system 1, the distribution device 20 sets the priority of distribution methods based on the optimization information and notifies the reception device 30 of the priority. Therefore, the receiving device 30 is not limited to a specific distribution method, and can secure a degree of freedom to select an acquisition method according to its own situation.

  Further, the distribution system 1 centrally manages the distribution method in the distribution status management device 10 and provides the distribution method list to the receiving device 30 in response to a request. Since the receiving apparatus 30 determines an acquisition method based on a predetermined determination criterion from the distribution method list, procedures depending on the distribution method are automated for both the distributor and the user. As a result, the content provided by a plurality of distribution methods can be easily acquired by the receiving device using a method suitable for the current situation, and the user can acquire the content by the same operation regardless of the type of distribution method.

  Further, the receiving device 30 can dynamically change the content acquisition method by receiving a distribution method list periodically from the distribution status management device 10 or by receiving an update notification from the distribution status management device 10. . As a result, the user can use the content whose acquisition method has been changed without performing any special operation without interruption or without knowing that the content has been changed.

  Thus, the distributor can expect a reduction in distribution cost by enabling efficient selection of a distribution method. On the other hand, as a user, optimization of the content users as a whole can be expected to improve the efficiency of the method of acquiring the content used.
