Background technique

Recording and broadcasting, like on-demand and live broadcast, is one of the main businesses in the video business. The recording first needs to record the video content and then play the recorded video content. Video content recording is divided into network recording and local recording. The network recorded the content recorded on the platform side and recorded locally on the set top box. Network recording is divided into shared network recording and non-shared network recording. A shared network recording is a media file that multiple users can share and a non-shared network recording is a recorded media file that can only belong to one user and can only be played by the user to which it belongs.

In prior art non-shared network recording, the headend system is used to modulate a program source obtained from satellite, terrestrial, cable television, etc., and transmit it to a media server. The media server performs network recording of the video. The video content can also be output from the media server to the set top box via the CDN, and the set top box locally records the video content. The operations management platform manages the process of network recording and local recording.

A local device such as a set-top box or other mobile phone or tablet computer requests the operation management platform to perform network recording on the specified video content. The operation management platform notifies the media server to perform network recording on the specified video content. For a program, there may be multiple local devices requesting recording.

detailed description

The technical solutions of the embodiments of the present invention are further described in detail below through the accompanying drawings and embodiments.

FIG. 1 is a structural diagram of a system for video recording according to an embodiment of the present invention. As shown in FIG. 1, it includes a head end device, a media server, an operation management platform, and a terminal device. The head end device receives the satellite signal or the streaming media file provided by the content provider, and converts the code into a media stream or a media file conforming to the service standard, and is responsible for introducing the content. The media server provides content storage and content service capabilities. Operation management platform provides operators with content management, business management, product management, subscriber management, partners Management, device management and other functions. The terminal device provides a service display and content play function for performing a service experience through the terminal. Terminal device types include STB (Set-Top-Box), personal computer (PC), and smart phones using the mobile operating system (IOS) developed by Apple or the operating system (Android) developed by Google Inc. Tablet PC (Tablet Personal Computer), etc.

In a specific embodiment of the present invention, the terminal device includes multiple pieces for transmitting a video recording request to the operation management platform, where the video recording request includes a user identifier and a program identifier of a program to be recorded video. After receiving the video recording request sent by the multiple terminal devices, the operation management platform determines, according to the program identifier included in the video recording request, the total number of times that the program corresponding to each program identifier needs to perform video recording. The operation management platform further determines, according to the total number of video recording requests of the program corresponding to the program identifier, the number of video files that the media server needs to record when sending the video recording task to the media server, and the determined video recording task is The media server sends. The head end device is configured to acquire a media file and send the media file to a media server. The media server receives the media file sent by the head end device and performs video recording according to the received video recording task sent by the operation management platform.

FIG. 2 is an operation management platform according to an embodiment of the present invention. As shown in FIG. 2, the operations management platform includes a processor, a memory, and a memory. The operation management platform is configured to receive a video recording request sent by multiple terminal devices. The video recording request is processed and sent to the media server, and the video is recorded by the media server.

In an example, the operation management platform and the terminal device are connected through a communication interface, and the video recording request sent by the terminal device includes a user identifier (UID, User Identity) and a program identifier (PID, Program Identity) of the program to be recorded. The UID and PID are stored in the memory of the operation management platform.

The operation management platform receives a video recording request sent by a plurality of terminal devices, and the video recording request may include the same PID and/or a different PID. The processor counts the number of received identical PIDs, determines the number of recordings of the program corresponding to the same PID, and forms a list of video information to be recorded.

In an example, FIG. 3 is a list of video information to be recorded stored in an operation management platform according to an embodiment of the present invention. As shown in FIG. 3, the information of the video to be recorded includes a UID and a PID. Assume that there are 1000 programs in the video recording request sent by the terminal device received by the operation management platform, and the PID is “A10011”, and the record between the program identifier A10011 and the request recording terminal identifier is recorded in the table. Correspondence relationship.

The operation management platform receives a video recording request sent by the terminal device before the program is broadcasted. In one example, the program, such as "news", has a play time of 19:00, and the operated management platform receives a video recording request for the "news" program sent by the terminal device before 19:00.

In one example, the operations management platform periodically counts video recording requests sent by the terminal devices received during the period. Add the statistics to the list of video information to be recorded on the operation management platform. For example, in one cycle, the operations management platform receives five video recording requests. The PID of the first request is "A10011" and the UID is "12345678". The PID of the second request is "B12011" and the UID is "87654321". The PID of the third request is "A10011" and the UID is "12345778". The PID of the fourth request is "B12011" and the UID is "87654320". The PID of the fifth request is "A10011" and the UID is "12345677". Then, the corresponding content of the first request, the third request, and the fifth request are added to the list of the to-be-recorded video information whose PID is "A10011", and the corresponding contents of the second request and the fourth request are added to the PID. It is in the list of "B12011" video information to be recorded.

The processor further determines a different recording identifier (RID, Record Identity) for the video recording request of different terminals of the same PID. In a specific embodiment of the present invention, when it is determined that one PID has 1000 UIDs to request recording, the processor determines 1000 RIDs for the PID, and corresponds to one RID for the recorded 1000 video files. The RID and the UID are in one-to-one correspondence, that is, a video file corresponding to one RID can only be played by the UID corresponding to the RID.

In a particular embodiment of the invention, not all set top boxes will watch the recorded video as soon as the video recording is complete. Therefore, you do not need to complete all video recording tasks at once, and you can progressively record video recording tasks. FIG. 4 is a diagram of a relationship between time and playback amount of a first request for video playback according to an embodiment of the present invention. As shown in FIG. 4, the horizontal axis shown represents time, wherein the horizontal axis indicates the time at which the media server starts recording video at the coordinate origin. The vertical axis indicates the number of terminal devices that have completed the first video playback request. The curve shown is a time-to-quantity curve for completing the first play request. When in the system of the specific embodiment of the present invention, the number of recorded video files should be greater than or equal to the arbitrary time point at any point on the curve. The number of terminal devices that complete the first video play request on the curve, the recorded video can satisfy the requirement of the terminal device to request the playback of the recorded video file.

Then, the origin is a straight line tangent to the curve, and the number of recorded videos corresponding to each time point on the straight line is greater than or equal to the number of terminal devices that complete the first video playback request at the time point. the amount. Thus, the number of video files recorded at various points on the line tangent to the origin and the curve is the minimum recording requirement at that point in time. At any point in time, when the number of recorded video files is always greater than the number of video files recorded at the corresponding time points on the straight line passing through the origin of the time point, the terminal device can complete the recording completion. The request for playback of a video file.

In an example, if the total number of video files to be recorded is N, the time required to complete the N number of video recordings is the time corresponding to the intersection of the total number N of the video to be recorded and the minimum recording requirement line (ie, in the figure) Time point T). If the origin is O, the time at which the first video recording is completed is D (ie, the duration of the program), the time for completing all video recordings is T, and the total number of videos to be recorded is N, and the number of recordings completed in each unit time D is B. Then, the number B that needs to be recorded in unit time D can be calculated as:

B=N*D/T.

After the operation management platform calculates the number B of video files to be recorded in a unit time, the video recording task is sent to the media server. The video recording task includes the number B of video files to be recorded, and the media server starts B. Video recording task. In an example, after the media server completes the video recording task and records the B video files, the recording management success response is fed back to the operation management platform, and the operation management platform may send a video recording request to the media server again. The number of videos to be recorded this time is included in the secondary video recording request until all video recordings (N) are completed.

For example, the number of video files that need to be recorded for one program is 10000, and the broadcast time of the program is one hour. The recording duration of the program determined according to the time curve of the first request for video playback by the terminal device is 20 hours. According to the above calculation formula, it can be concluded that the number of recording tasks to be completed per unit time D (within one hour) is 500. The number of video recording tasks in the video recording task sent by the operation management platform to the media server in a single time is 500. In this way, the number of recording tasks that need to be managed by the operation management platform is reduced, and the number of recording tasks simultaneously initiated by the media server is greatly reduced, thereby reducing resource consumption of the operation management platform and the media server, and improving device performance.

FIG. 5 is a media server according to an embodiment of the present invention. As shown in FIG. 5, the media server includes a memory, a processor, a memory, and a communication interface. The media server receives the video recording task sent by the operation management platform through the communication interface. In an embodiment, the video recording task may include a recording identifier segment formed by a plurality of recording identifiers (for example, B) and a program identification segment of the program to be recorded. The program identification segment of the program to be recorded may include, in addition to the program identification of the program, a program name, a start time and an end time broadcasted by the program, and a broadcast frequency band. The recording identifier segment includes a plurality of recording identifiers, and the number of the recording identifiers is the same as the minimum recording requirement. The number of video files to be recorded can be determined by determining the number of the recording identifiers in the recording identifier segment. In one example, the recording identifier included in the recording identifier segment in the video recording task is: “L10001-L10500”. Therefore, it is determined by the recording identifier segment that a program needs to be recorded 500 times to form 500 video files, and each of the video files can be sequentially assigned recording identifiers from L10001 and L10500. For example, the recorded first video file has the recording ID of L10001, the recorded second video file has the recording ID of L10002, and so on. In another embodiment, the video recording request received by the media server may only include the program identifier and the number of times the program needs to be recorded, and the media server starts multiple recording tasks according to the number of times the program needs to be recorded, and after completing multiple recording tasks. Multiple video files are formed, and then each video file can be further assigned a recording identification.

In one example, the program identification of the program to be recorded is used to distinguish between different programs, the recording identification being used to distinguish different recorded video files of the same program. For example, program A and program B have different program identifications. When program A needs to be recorded 500 times, the recorded 500 videos have the same program identification and different recording identifiers.

The processor sends an instruction according to the program identifier of the video to be recorded, instructing the communication interface of the media server to receive the media file corresponding to the program identifier sent by the head end device. The communication interface receives the media file from the head end device according to the program name in the program identification, the started start time and end time broadcasted, and the broadcasted frequency band.

In a specific embodiment of the present invention, the processor is further configured to send a cache instruction to the memory, and instruct the memory to cache the media file received by the communication interface. .

In a specific embodiment of the present invention, the memory of the media server further includes a recording information table. FIG. 6 is a recording information table according to an embodiment of the present invention. As shown in FIG. 6, the recording information table includes the program identification, the recording identification, the file name, and the address of the file storage of the program to be recorded. In one example, the media server receives a video recording task sent by the operations management platform. The recording identifier in the recording information table and the program identifier of the program to be recorded are determined according to the recording identifier segment sent by the operation management platform and the program identifier of the program to be recorded. For example, a video recording request sent by the media server includes a program identifier of the program to be recorded as A10011 and a recording identifier segment of L10001-L10500, and determining, according to the recording identifier segment, that the recording identifier segment includes 500 recordings. Identification, each recording has the same program identification. Therefore, 500 items are added to the recording information table, and each item corresponds to one recorded video file. For example, the recorded video of the first video file recorded is A10011, the recording ID is L1001, the recorded video of the recorded second video file is A10011, the recording ID is L10002, and so on, until it is completed. Recording of the fifth hundred video files, The recording program list of the fifth hundred video files is identified as A10011, and the recording identifier is L1500. In a specific embodiment of the present invention, when the media server completes the video recording task, the file name of the video file and the address (URL, Uniform Resoure Locator) stored in the video file are also added to the recording information table.

After completing the video recording task sent by an operation management platform, the media server also returns a result to the operation management platform that issues the task. In one example, the result of the media server returning the video recording task to the operations management platform is in units of a recorded video file. For example, when a video recording task sent by an operation management platform to a media server includes 500 recordings of the video, the media server sends 500 notifications to the operation management platform, and the result of each notification includes a video. The program ID, recording ID, file name, and URL of the file.

In a specific embodiment of the present invention, the operation management platform is further configured to receive a notification sent by the media server. After receiving the notification of the completion of the video recording task sent by the media server, the operation management platform sends a notification of the completion of the video recording to the terminal device that sends the video recording request of the program identifier, so that the terminal device determines that the video recording is completed and can Request playback of the recorded video file. In an example, the operation management platform may send a notification that the video recording is completed to the determined terminal device, and may notify the online local device that records the video of the program identifier, so that the online terminal device can Open the video file. When the local device that is not notified is online, the local device of the new online device is notified that the video recording is completed, and the completed video file can be played. In a specific embodiment of the present invention, after determining that the video recording is completed, the terminal device sends a play request of the video file to the operation management platform. The play request of the video file sent by the terminal device to the operation management platform includes a user identifier and a program identifier.

The operation management platform receives a video file play request sent by the terminal device, and acquires a user identifier and a program identifier included in the request. The operation management platform allocates a video file including the program identifier that does not include the user identifier to the terminal device, and adds the user identifier of the terminal device to the video file allocated to the terminal device.
