Embodiment 1

[0032] like Figure 1a As shown, it is a schematic diagram of the implementation flow of the program recording method provided by the embodiment of the present invention, which may include the following steps:

[0033] S11. According to the received IP multicast signal, record the program according to the preset recording duration, and generate a corresponding recording file, the recording file includes a transport stream TS file.

[0034] During specific implementation, the recording server receives the IP (Internet Protocol, Internet Protocol) multicast signal sent by the broadcasting network. Record the program and generate corresponding recording files, wherein the preset recording time is 30 minutes, and the recording files may include but are not limited to TS (Transport Stream, transport stream) files, index files and multiple double-speed files.

[0035] Specifically, the TS file is used to store the media data information of the program, the index file is used to reco...

Embodiment 2

[0079] Embodiment 2 provides a program recording device. Since the problem-solving principle of the device is similar to the above-mentioned program recording method, the implementation of the device can refer to the implementation of the method, and repeated descriptions will not be repeated.

[0080] like figure 2 As shown, it is a schematic structural diagram of a program recording device provided by an embodiment of the present invention, including: a recording unit 21, a segmentation unit 22 and a generating unit 23, wherein:

[0081] The recording unit 21 is configured to record the program according to the preset recording duration according to the received Internet protocol IP multicast signal, and generate corresponding recording files, the recording files include transport stream TS files.

[0082] The segmentation unit 22 is configured to virtually divide the TS file into several TS slices according to the preset slice duration.

[0083] The generation unit 23 is ...

Embodiment 3

[0099] like image 3 As shown, it is a schematic diagram of the implementation process of the broadcasting method of the program based on the DVB broadcasting system in the embodiment of the present invention, which may include the following steps:

[0100] S31. Send a DVB playback request of the normal double speed of the recorded program to the playback device.

[0101] During specific implementation, the normal double-speed DVB playback request sent by the client is received. The request can be a recorded program of any time period, such as the request time is from 2015-12-01 12:00:00 to 2015-12-01 13 :00:00, for the convenience of description, the embodiment of the present invention uses this time period as an example for description.

[0102] S32. Send an index file download request corresponding to the program.

[0103] During specific implementation, when the playback device receives a playback request for a recorded program, it can directly obtain the program name an...

Abstract

The invention discloses a program recording method and device. The program recording method is used for playing videos on a DVB video playing system and an OTT TV playing system simultaneously so as to reduce hardware cost. The program recording method includes: recording a program according to a preset recording time length according to a received IP multicast signal to generate a corresponding recorded file, wherein the recorded file includes a transport stream TS file; virtually segmenting the TS file into a plurality of TS clips according to a preset clip time length; and generating virtual clip files according to the positions of respective TS clips in the TS file.

Description

technical field [0001] The invention relates to Internet television technology, in particular to a program recording method and device. Background technique [0002] With the development of Internet technology, traditional DVB (Digital Video Broadcasting, Digital Video Broadcasting) video playback can no longer meet the needs of users. Users hope to watch TV through terminals such as TV set-top boxes, PCs (Personal Computers, personal computers) and mobile phones. Programs, such as OTT (Over The Top) TV (Internet TV) appeared. [0003] OTT TV is a video program transmitted through the Internet, such as PPS (PPS Internet TV), UUSEE (UUSEE Internet TV) and other platforms to transmit content to the display screen (including TV), and its terminals can be TV sets, computers, set-top boxes, PAD, smart phone and so on. [0004] In traditional DVB video playback, after the video is modulated by IPQAM, it is transmitted through the radio and television network, and the set-top box...
