Embodiment 1

[0054] Embodiment 1 of the present invention provides a method for network personal video recording. It should be pointed out that the method of the present invention can be applied to different system architectures, and after the method of the embodiment of the present invention, similar image 3 The system architecture diagram of the present invention is combined with the method of the present invention, and the specific implementation process is set forth, such as figure 1 As shown, the methods include:

[0055] In step 201, a first nPVR recording request is received, wherein the first nPVR recording request carries a first nPVR program list and a user identifier.

[0056] The user identifier may be the user's account, or an ID number similar to a data card inserted into a set-top box, or a mobile phone number similar to a smart phone. The corresponding first nPVR program list can be expressed as an episode, or as a segment with a specified start time and end time in a spe...

Embodiment 2

[0135] The embodiment of the present invention is based on the method process described in embodiment 1, combined with image 3 The system architecture shown is a description of the specific process of the nPVR management server processing the user's nPVR recording request. Such as Image 6 As shown, the following specifically describes the process of an nPVR recording:

[0136] In step 301, the user side (STB) initiates an nPVR recording request to the nPVR management server.

[0137] In step 302, after receiving the nPVR recording request, the nPVR management server accesses the CDN media control server to query the channel time-shifted recording information according to the nPVR program list.

[0138] In step 303, the CDN media control server returns the time-shifted recording information of the channel corresponding to the nPVR program list.

[0139] In step 304, after the nPVR management server obtains the time-shifted recording information of the channel corresponding...

Embodiment 3

[0144] The embodiment of the present invention is based on the method process described in embodiment 1, combined with image 3 The system architecture shown is a description of the specific process of the nPVR management server processing the user's nPVR recording request. Such as Figure 7 As shown, the user side (set-top box) browses the EPG page, obtains the user's nPVR record list from the nPVR management server, and can select one of the nPVR records to play. The specific nPVR play process is as follows:

[0145] In step 401, the set-top box at the user side initiates an nPVR play request to the nPVR management server.

[0146] In step 402, after the nPVR management server receives the playback request from the user side, it records the CDN media control server address Cdnipaddress according to the nPVR record, the first-level index file name TopindexName in the channel time shift, and the starting point of the nPVR program list selected by the user. The start time (St...

Abstract

The invention relates to the technical field of IPTV and OTT internet multimedia, and provides a network personal video recording method and device. The method comprises the steps that a first nPVR recording request is received, and the first nPVR recording request carries a first nPVR program list and a user identifier; recording information of channel time shifting is queried according to the first nPVR program list; if the channel time shift corresponding to the first nPVR program list is determined according to the recording information, the channel time shift is in a recording completionstate or a recording state; and index information of the first channel time shift is obtained, and a mapping relationship between the user identifier and the index information of the first channel time shift is established. According to the invention, the nPVR services of all the users directly share and use the live channel time shift to record the programs, so that the waste of storage resourcescaused by opening up an independent space for each user to store a large number of same programs is avoided.

Description

【Technical field】 [0001] The invention relates to the field of IPTV and OTT Internet multimedia technologies, in particular to a method and device for network personal video recording. 【Background technique】 [0002] With the advancement of the integration of the three networks and the rapid development of Internet TV, users are no longer satisfied with the "one-way transmission" and "passive reception" TV viewing methods, and have put forward higher requirements for the personalization and interaction of TV services; in view of For this reason, operators vigorously develop nPVR (Network Personal Video Recording, Network Personal Video Recording) value-added interactive services. [0003] The traditional personal video recording service saves the recorded content in the hard disk on the user side, which not only increases the cost and price of the set-top box, causes the loss of some potential users, but also greatly increases the complexity of device management and maintena...
