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

Embodiment Construction

[0059] In the method of the present invention, TSTV is still recorded and stored according to the previous method, and for the processing of TVOD, it is realized by querying whether there is TVOD in this time period on TSTV, and unified storage is realized by this method. According to the needs, the designated recording and broadcasting programs can be archived.

[0060] The present invention mainly relates to several parts such as content management engine (Content Managerment Engine, CME), media control unit (Media Control Unit, MCU) and streaming media server (Streaming Server, SS) connected by network in IPTV business system, as figure 1 shown.

[0061] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0062] In this embodiment, after the content management engine of the IPTV service system receives the recording request, it generates a TVOD recording task, and then the media con...

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. The IPTV system can provide video on demand (Video on Demand, VOD), live TV (Live TV), time-shifted TV (Time-shifted TV) and recorded program on demand (TV on Demand, TVOD).
