Embodiment 1

[0042] The embodiment of the present invention provides a hybrid transmission method, such as figure 1 Shown, including:

[0043] 101. When determining the first program of the program list to be played according to the playing time of each program, the server reads the program type of the first program.

[0044] Wherein, the program list includes the playing time, program type, and program source address of each program, and the program type is used to indicate that each program is a live program or an on-demand program.

[0045] The embodiment of the present invention provides a hybrid transmission method. The live program and the on-demand program are compiled into the same playbill, and then the on-demand program is converted into the slicing mode of the live program according to the time prompt of the playbill using the slicing technology, and then unified use The HLS-like protocol completes the program transmission operation, which not only realizes the unified transmission of ...

Embodiment 2

[0058] The embodiment of the present invention provides a method for hybrid transmission of multimedia files, such as figure 2 Shown, including:

[0059] 201. The server generates a program list.

[0060] The embodiment of the present invention provides a hybrid transmission method. The live program and the on-demand program are compiled into the same playbill, and then the on-demand program is converted into the slicing mode of the live program according to the time prompt of the playbill using the slicing technology, and then unified use The HLS-like protocol completes the transmission operation of the program, which not only realizes the unified transmission of on-demand programs and live broadcasts, but also provides users with a seamless integration of recording and live broadcast viewing experience.

[0061] Specifically, the method for generating the program list is to receive the name of each program and the playing time of each name input by those skilled in the art, and th...

Embodiment 3

[0091] The embodiment of the present invention provides a server, such as image 3 Shown, including:

[0092] The acquiring module 01 is used to read the program type of the first program from the program list when it is determined that the first program in the program list needs to be played according to the program play time contained in the program list;

[0093] The processing module 02 is configured to, if the program type of the first program indicates that the first program is a live program, obtain the live stream of the first program according to the program source address of the first program in the program list, and adopt a streaming mode to transfer The live stream is sliced ​​to generate live stream slices and live stream slice index files; and if the program type of the first program indicates that the first program is an on-demand program, download the first program according to the program source address of the first program in the program list On-demand resources, ...

Abstract

The embodiment of the invention provides a mixed transmission method and a server. The unified transmission of a request program and a live program is realized by using a slicing technology and the viewing experience of seamless fusion of recorded broadcast and direct broadcast is provided. The scheme comprises the steps of reading a program type of a first program from a program list when the first program is determined based on program broadcasting time contained in the program list; if the first program is a direct broadcast program, obtaining a direct broadcast stream of the first program based on a program source address of the first program, slicing the direct broadcast stream, generating direct broadcast stream slices and direct broadcast stream slice index files, and outputting the first program according to the direct broadcast stream slices and direct broadcast stream slice index files based on a similar HLS protocol; and if the first program is a request broadcast program, downloading a request broadcast source of the first program based on the program source address of the first program, slicing the request broadcast source, generating request broadcast slices and request broadcast slice index files, and outputting the first program according to the request broadcast slices and request broadcast slice index files based on the similar HLS protocol.

Description

Technical field [0001] The present invention relates to the field of multimedia Internet, in particular to a hybrid transmission method and server. Background technique [0002] With the increasing development of science and technology and the widespread popularity of network multimedia, high-definition and smooth network video live broadcast has become the highlight and advantage of today's network video. With the increase in the penetration rate of home computers and smart TVs, network high-definition video and content continue to increase, and users' demands for humanity and intelligence in the process of watching live streaming media and on-demand multimedia files continue to increase. [0003] In the prior art, for live streaming media, HLS-like (HTTP Live Streaming, HTTP streaming media network transmission) protocols are usually used to realize the transmission and playback of live streaming, and then video slicing technology is used to solve the live streaming time shift of...
