Recording method and profiling method for play-on-demand program

Abstract

The invention discloses a recording method of a recording video-on-demand business and an archiving method applying to an Internet Protocol Television (IPTV) business system which provides a Time-Shifted Television and a Television On Demand business. The IPTV business system real-timely records the video of a time-shifted channel and fragment stores according to the video recording of the TSTV business and a storage mode, and deletes the fragment when the storage time period of the fragment is longer than a presetting time period; the IPTV business system receives a recording request of the TVOD business, parses the time-shifted channel and a time segment where the request recording video content is, if the time length of the time segment is shorter than the presetting storage time length, queries whether the stored recording content contains the video content after the time segment reaches over, if so, returns a successfully recorded response to a recording request sender. The method uses the TSTV recording content to implement the recording of the TVOD, saves the recording magnetic array space. Furthermore, the invention also provides the method for implementing a TVOD archiving assignment by using the TSTV recording content.

Description

technical field [0001] The invention relates to the field of multimedia services, in particular to a recording method and archiving method for recording program on demand. Background technique [0002] The IPTV (Internet Protocol Television) service is a broadband value-added service that connects a set-top box to a broadband network and uses a computer or a TV as a display terminal to provide users with an interactive TV experience and multimedia services.

AI Technical Summary

Problems solved by technology

[0010] 1. The current TVOD can only make a recording plan a period of time in advance through external systems such as the service management system (SMS) and user set-top boxes, and cannot modify the recording information after the recording starts

[0011] 2. The content recorded by TSTV and TVOD services has a lot of repetitions, which wastes the space of the magnetic array; on the other hand, most of TVOD is also time-sensitive and needs to be deleted after a period of time. This kind of repeated recording and deletion operations, Greatly increases the disk array I / O operation of the streaming media, reducing the performance and service life of the streaming media server
