Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0036] like figure 1 As shown, the embodiment of the present invention relates to a method for implementing NPVR services, including:
[0037] Step S101, after receiving the NPVR request, the business system sends the NPVR request to the CDN system;
[0038] In this step, the user sends an NPVR request to the service system through the user terminal, requesting to record related programs. After receiving the NPVR request, the business system sends the NPVR request to the CDN system; the CDN system records the program.
[0039] Step S102, the CDN system controls the NPVR node corresponding to the NPVR request to record the program, and after the recording of the program is completed, the CDN...

The invention discloses a method and device for realizing NPVR services, comprising: after receiving the NPVR request, the service system sends the NPVR request to the CDN system; the CDN system controls the CDN node corresponding to the NPVR request to record the program, and the recording program is completed Finally, the CDN system sends a storage request to the storage system; the storage system obtains the NPVR file obtained by recording the program from the CDN system according to the storage request, saves it, and then notifies the service system through the CDN system that the NPVR service is completed. The present invention stores the NPVR content in the storage system through the CDN system, and the NPVR content in the CDN system is no longer archived, but is processed as ordinary TVOD content, and can be aged (deleted) after the aging time is reached; Due to the increase of NPVR business demand due to the increase of users, the storage space of the CDN system is insufficient.
Description
technical field [0001] The present invention relates to the technical field of multimedia services, in particular to a method and device for realizing NPVR (Network Personal Video Recorder, Network Personal Video Recorder) services. Background technique [0002] The multimedia business involves services such as Internet Protocol Television (IPTV), Mobile Video Streaming System (MVS, Mobile Video Streaming), and mobile TV. Internet TV is an Internet-based multimedia technology, based on the existing network bandwidth infrastructure, and provides users with a variety of interactive digital media services through Internet protocols. With the improvement of network bandwidth and the development of network technology, the development of media value-added services based on multimedia networks such as Internet TV has gradually become a trend. [0003] In a multimedia service system, multiple media servers (nodes) are usually used to form a content distribution network (content dis...
