Background technique

In the current field of network video communication, such as the IPTV/OTT system, for the same channel, basically every recording server is recorded, and the recorded programs are the same. Since many places require 220 channels to record for 7 days, the current channel's bit rate is gradually moving toward HD 4K. If the average bit rate of the channel is 5M, the space required to store the program alone is 220*7*24*60. *60*5=666T, if we count our system is 1:1 backup storage, then the total space required to store so many programs is 1332T. At present, the largest data disk used for system storage is the 4T SATA disk. That is, 333 such SATA disks are required. Each disk is calculated according to 1500 yuan, which requires nearly 50W yuan. For the IPTV/OTT system, more important is the on-demand and live content. If the storage of the simple program is so expensive, the cost is too high, and as the HD 4K becomes more and more popular, the space will be needed. getting bigger.

Embodiments of the invention

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Embodiment 1

The method for program recording control of this embodiment, as shown in FIG. 1, includes the following steps:

Step S101: The management server acquires the heat information of the program from the heat statistics server before the cache time of the program arrives;

In this step, two time attributes are generally set at the time of channel creation, one is the buffer time T1 (tstvtime), and the other is the TVOD time T2 (tvodtime); where T2>=T1. The recording server uses unified storage to store the program. If there is no recording plan (ie, recording task), the channel fragment will be deleted after the T1 time is reached; if there is a recording plan, then Fragments of the recording server will not be deleted until T2. Therefore, the management server needs to obtain the heat information of the program from the heat statistics server before the program cache time is reached, or the program cannot be recorded after the program is deleted. The hot server and the management server here can also be the same server. The heat information here indicates how much attention is paid to the program, that is, how many people like the program; it can be embodied by the number of times of the program, the number of times of collection, the number of comments, the number of comments, and the viewing time, etc., and should be understood as long as it reflects whether the program is a hot spot, Everyone can welcome the show. For example, at present everyone likes to watch "Run, Brother" and "I am a singer", but for some science and education films "Animal World" is relatively small, such as "Run, Brother" on-demand times 500 million times and "I am The singer "on-demand frequency is 600 million times, while the "Animal World" is broadcasted 80 million times. The related art records these programs on all recording servers (if there are 220 recording servers) for on-demand viewing by subsequent users. Obviously, if the "animal world" is recorded and stored in each recording server, it takes up an unnecessary recording server, resulting in waste of resources and high cost.

Step S102: The management server determines, according to the heat information, the number of recording servers for recording the program;

In this step, the management server sees whether the program is a hot spot. If it is a hot spot, it means that there are many people on-demand, and it can be predicted that there will be more users to use later, then more recording servers are needed. The program is stored and stored to ensure that there are enough resources for the user to use. If it is not a hot program, it means that there is less on-demand, and there will be fewer people to order the program later, so there is no need to occupy more recording servers. The recording server here is a server that represents a storage function and can provide an on-demand service for a user. Combined with the above examples, such as "Run, Brother" on-demand frequency of 500 million times and "I am a singer" on-demand frequency of 600 million times, there may be more people on-demand, then use 100 recording server to Recording and storage; "Animal World" on-demand frequency of 80 million times, may be less on-demand people, then use 10 recording servers for recording and storage.

Step S103: The management server selects a corresponding number of recording servers according to the determined number;

In this step, the number of recording servers determined in the above step S103 is selected from those recording servers to be recorded. In conjunction with the example in the above steps, it is determined in step S103 that the number of recording servers for recording the "Animal World" program is ten, then 10 recording servers are selected.

Step S104: The management server delivers a recording task for notifying the recorded program to the selected recording server.

In this step, the recording task corresponding to the program is delivered to the corresponding selected recording server. Add a recording task to the corresponding recording server, that is, insert the recording task in the recording task table, and then the recording plan will be sent to the corresponding recording server. In combination with the above example, if the recording task of recording the "Animal World" program is sent to the corresponding 10 recording servers, the recording server without the recording task does not need to record the "Animal World" program. Reduce storage space, which in turn reduces the cost of the recording server.

In the above step S102, when the heat information includes the number of times of on-demand, the management server determines, according to the heat information, the number of recording servers for recording the program, including: the management server uses the number of times of the video as the heat value of the program; and sets the plurality of recording servers to multiple levels. Recording server, the recording server of different levels includes at least one recording server; the management server determines the recording server of the corresponding level according to the heat value. Here, according to the number of times of program on-demand, how many recording servers are selected. In order to facilitate management and operation, the recording server is divided into levels, for example, a certain number of recording servers are set to one level, and when the preset conditions are met, Directly start all recording servers at this level, which ensures that the selected recording server is quickly determined while saving storage space. In combination with the above example, if 220 recording servers are set to 3 levels, namely level 1, level 2, and level 3; there are 50 recording servers in level 1, and 70 recording servers in level 2, level 3 There are 100 recording servers in it. If the on-demand ten million is a heat value, then "Run, Brother", "I am a singer" and "Animal World" respectively have a heat value of 60, 50, and 8; and if the preset heat value is greater than 0, 30 corresponds to level 1; when the heat value is greater than 30 and less than 60, it corresponds to level 2; when the heat value is greater than 60, it corresponds to level 3; here, when level 2 is selected by default, the recording server in level 1 is also started, and when level 3 is used, Start the recording server in level 1 and level 2, that is, when the heat value is greater than 30 and less than 60, it corresponds to all recording servers in level 1 and level 2; when the heat value is greater than 60, it corresponds to all of level 1, level 2, and level 3. Recording server, if it is "running, brother" and "I am a singer" to adopt level 2, then it will start level 1 at the same time and start the recording server in level 1 and level 2 to "run, brother" and " I am a singer" for recording storage, that is, using 120 recording servers to record and store "Run, Brother" and "I am a singer". And "Animal World" has level 1 for recording and storage, that is, recording and storing "Animal World" with 60 recording servers. The level setting of the server here is only for the convenience of management, as long as the method of selecting an appropriate number of recording servers according to the heat information of the program can be realized.

In order to more accurately estimate the number of times of program on-demand, the weighting calculation can be performed according to the number of times of program on-demand and the average number of times of on-demand of the channel corresponding to the program, so that the heat value is more reasonable. That is, in the above step S102, when the heat information includes the channel identification information and the number of times of on-demand, one channel includes a plurality of programs; the management server determines the number of recording servers for recording the program according to the heat information: the management server finds the channel identification information according to the channel identification information. The average on-demand frequency of the corresponding channel; the management server determines the popularity value of the program according to the number of times of on-demand and the average number of on-demand times; setting a plurality of recording servers as recording servers of multiple levels, and the recording servers of different levels include at least one recording server; the management server The recording server of the corresponding level is determined according to the heat value. Here, not only the number of times of the program itself, but also the average number of times of the channel corresponding to the program, that is, the heat information of the channel. The determining, by the management server, the popularity value of the program according to the number of times of the on-demand and the average number of on-demand times may include: multiplying the number of times of the on-demand by the first weighting coefficient to obtain a first heat value; and multiplying the average number of times of the on-demand by the second weighting coefficient to obtain a second heat value; The sum of the weighting coefficient and the second weighting coefficient is 1; the sum of the first heat value and the second heat value is taken as the heat value of the program. The weighting value can be set according to the actual situation, that is, the first weighting coefficient and the second weighting coefficient value can be set according to actual conditions. In combination with the above example, if 220 recording servers are set to 3 levels, namely level 1, level 2, and level 3; there are 50 recording servers in level 1, and 70 recording servers in level 2, level 3 There are 100 recording servers in it. If the on-demand ten million is a heat value, it is assumed that "running, brother", "I am a singer" and "animal world" are all in the same channel, and the first weighting coefficient is 80%, and the second weighting coefficient is 20%; then "Run, Brother", "I am a singer" and "Animal World" respectively correspond to the heat values of 55.8, 47.8 and 8.2; and if the preset heat value is greater than 0 less than 30 corresponds to level 1; If the heat value is greater than 30 and less than 60, it corresponds to level 2; when the heat value is greater than 60, it corresponds to level 3; here, when level 2 is selected by default, the recording server in level 1 is started at the same time. When level 3 is used, level 1 and level 2 are started at the same time. Recording server, that is, when the heat value is greater than 30 and less than 60, it corresponds to all recording servers in level 1 and level 2; when the heat value is greater than 60, it corresponds to all recording servers in level 1, level 2 and level 3, if it is "running" Well, brothers and "I am a singer" Level 2, then the level 1 will be started at the same time, and the recording servers in level 1 and level 2 will be started to record and store "running, brother" and "I am a singer", that is, using 120 recording servers to "run" Well, brothers and "I am a singer" are recording storage. The "Animal World" uses Level 1 for recording and storage, that is, 60 recording servers to record and store "Animal World".

The plurality of levels of recording server settings include a first level recording server, a second level recording server, and a third level recording server; the management server determines the corresponding level of the recording server according to the difference in the heat value, including: when the heat value is greater than or equal to the first threshold, less than or equal to The second threshold is corresponding to the first level recording server; when the heat value is greater than the second threshold and less than or equal to the third threshold, the first level recording server and the second level recording server are corresponding; when the heat value is greater than the third threshold Corresponding to the first level recording server, the second level recording server, and the third level recording server. The first threshold, the second threshold, and the third threshold may be set according to actual conditions, where the number of recording servers included in the first level recording server, the second level recording server, and the third level recording server are also It can be set according to the actual situation.

Embodiment 2

In the program recording control method of the embodiment, the heat statistics server counts the number of times the program is played, and performs a series of processing on the program. First, a heat statistics table A1 is added to the heat statistics server to record the on-demand heat of the program list. See Figure 2 for a schematic diagram of the field structure of the table.

Nodeid (server ID): is the recording server ID;

Channelid: is the channel identifier, a Channelid indicates a channel;

Cid (program identification): is the identification of the program list;

Number (number of times of on-demand): is the number of times the program list is requested by the user;

Endtime: the end time of the program list;

Tstvtime (cache duration): The buffer duration of this channel.

As shown in Figure 3, the following steps are included:

Step S201: stb plays a certain program, and starts reporting data from the on-demand Library process

Step S202: The database receives the reported number of times of reporting, and queries whether there is a record corresponding to the program in the A1 table, and if there is any, adds 1 to the number; if there is no such record, the record is added in the A1 table. And number is 1.

Step S203: Start the timed task 1 and execute it once an hour. The timed task is used to search the A1 table for the record that meets the judgment condition 1;

Step S204: The judgment condition 1 here is the current time - 3 hours = <endtime + tstvtime = < current time - 2

Using the judgment condition, the program for the tstvtime program or the shard is searched for 2 hours before being deleted, and reported to the MDP (management server) in advance;

Step S205: The program that is searched for according to the judgment condition 1 is queried and uniformly reported to the MDP. If there is a lot of content to be searched, the flow control may be considered and reported in batches.

Step S206: Another timed task 2 is also executed every hour, and the timed task is used to search the A1 table for the record that meets the judgment condition 2;

Step S207: The judgment condition 2 here is: Endtime+tstvtime> current time

The judgment condition has already reached tstvtime for the program that has been reported, and the record needs to be deleted;

Step S208: The programs searched for the matching condition 2 are uniformly deleted.

When adding a recording server, set four levels of types for the recording properties, which correspond to the following:

Default Recording Server: The recording server that has been recording, or the recording server's channel is recorded from the beginning. This recording server is typically a recording center server.

Level 1 recording server: According to the results of the heat statistics, when the lowest interval (C1-C2) that meets the regenerative recording schedule is reached, the recording server of the recording plan needs to be delivered;

Level 2 recording server: According to the result of the heat statistics, when the middle interval corresponding to the re-generation recording plan is reached (C2-C3), the recording server of the recording plan needs to be delivered; when the heat is counted to the heat, the level 1 recording server A recording plan will also be issued.

Level 3 recording server: According to the result of the heat statistics, when the value that meets the regenerative recording plan exceeds a certain value (C3), the recording server of the recording plan needs to be delivered; where the heat is counted to the heat level, level 1 and 2 The recording server will also issue a recording schedule.

The values of C1, C2 and C3 can be set by themselves, and can be flexibly configured and modified according to the actual situation of the site operation and the needs of the local authorities.

According to the above description, two heat statistics tables A2 and A3 are maintained on the MDP side, both of which are used to estimate the subsequent user-on-demand behavior of the program of the channel, wherein the A2 table is counted for each program. More detailed and specific; and the A3 table is the average of the statistics of the daily program of the channel, more abstract; so according to the experience gained from the field observation, the value of the A2 table is weighted by 80%, for the A3 table The value is weighted by 20%.

Next, after calculating the weighted sum according to the values of the A2 and A3 tables, it is judged according to the value, in which interval; assuming that the calculated value is in the C1-C2 interval, then this generates a recording task for the level 1 recording server. Other levels of recording servers no longer generate recording tasks; assuming that the calculated value is greater than C3, recording tasks are generated on the Level 1, Level 2, and Level 3 recording servers, that is, all remaining recording servers are recording.

The recording time is required to be controlled before the cache time of the channel corresponding to the fragment arrives. Otherwise, if the corresponding fragment has been deleted when the recording plan is sent to the recording server side, the recording will fail. With the method in this example, there is no need to add hardware devices, and no additional large functional modules need to be added; therefore, the above two optimizations are implemented without substantially additional input, and are provided for operators and devices. Businesses can improve product competitiveness.

Embodiment 3

The method for program recording control in this embodiment is mainly described in the management server MDP. First, two tables are added to the heat statistics server, wherein the A2 table is basically the same as the A1 table on the recording server side, except that the nodeid is removed because There is no need to count the nodeid on the MDP side, which is the total number of on-demand statistics. For the heat statistics table A3, see FIG. 4, which is a schematic diagram of the field structure of the table, and the fields are explained:

Channelid: An identifier of a channel;

Number: The number of times the channel is averaged for each show in a day.

Since this A3 table is mainly for calculating the average value for each program of one channel, it is not necessary to add a field for distinguishing programs.

The detailed steps, as shown in Figure 5, include the following steps:

Step S301: Reporting the program and related information in accordance with the heat condition to the MDP every hour of the recording server side, and the MDP is ready to write to the database after receiving the data;

Step S302: After receiving the report information on the recording server side, the A2 table is written on the MDP side, that is, the database is written;

Step S303: Add a timed task here, which is executed every night at a fixed time. The timed task is mainly used to transfer the content in the A2 table that meets certain conditions to the A3 table.

Step S304: For the A2 table, it is determined whether the judgment condition 4 is met, and the judgment condition is as follows: Endtime+tstvtime>current time

The judgment condition here is that the program that has passed the cache time can be removed.

Step S305: The program in the A2 table that meets the above conditions is removed into the A3 table, and the removal here follows the following mechanism:

The record that meets the condition in step S304 is deleted in the A2 table;

Record the number of programs in the A2 table by channel classification;

Sort by channel and record the total number of on-demand times;

Calculate the average number of on-demand per program = total number of channels on demand / number of programs under the channel;

Write the channel channelid and the on-demand count of the average program to the A3 table;

At the same time, delete the original records in the A3 table.

Step S306: For the A2 table, another timing task is started at the same time, and the timing task is executed every hour;

Step S307: The timing task queries the program record of the A2 table, whether it meets the judgment condition 3: the current time -2<Endtime+tstvtime<current time-1

Step S308: If the record that meets the judgment condition 3 is queried in the step S307, the following records are processed for the queryed record:

Find the record and weight the corresponding number in the A2 table by 80%;

Find the number of the channelid in the association table A3 according to the channelid of the A2 table, and weight 20% on the number;

The two weighted values in steps 1 and 2 are added together to calculate the final weighted value of the program.

Step S309: determining the interval of the weighting value by using the weighting value calculated in step S308;

Step S310: If the weighting value is between C1 and C2, then for the recording corresponding to the programs, the recording task is added to the level 1 recording server, that is, the recording task is inserted in the recording task table, and there is a recording plan at that time. Send it to the corresponding recording server.

Step S311: If the weighting value is between C2 and C3, then for the recording corresponding to the programs, the recording task is added to the recording server of the level 1 and 2, that is, the recording task is inserted in the recording task table, and then there will be The recording plan is sent to the corresponding recording server.

Step S312: If the weighted value exceeds C3, the recording task is added to the recording corresponding to the programs, and the recording task is added to the recording server in the recording task table, that is, the recording task is inserted in the recording task table, and then the recording is performed. The plan is sent to the corresponding recording server.

The method of the embodiment innovates on the purpose of fine management and intelligent recording, so that the recording is more reasonable and intelligent, not all nodes or channels are recorded, but according to the number of times of the program and the previous The number of on-demand orders of the program under the channel is predicted, and based on this prediction, it is determined whether the program list will become a hot spot next, to determine how many recording servers should be recorded. With the increase of the number of recording servers and the number of channels in the future, and the gradual increase of the channel code rate, the previous extensive recording mechanism is difficult to adapt, and it can only be improved in the direction of refined management intelligent recording, in order to adapt to the new situation.
