Abstract

A system and method for video presentation delivery with edited and/or inserted content based on adaptive bit-rate streaming is provided. It does not incur large additional storage costs or introduce playback vulnerability to inconsistent player implementations or ad blocking software. Embodiments include, requesting from a client to a server, a personalized or edited media presentation for delivery, sending there from a personalized or edited media presentation with a continuous timeline based on an adaptive bit-rate video streaming protocol such as MPEG DASH or HTTP Live Streaming (HLS), a video server module that converts data based on the MPEG-4 ISO Base Media File format to an adaptive bit-rate video streaming protocol presentation, a module for converting an XML based media presentation, such as in the synchronized media integration language (SMIL), to the MPEG-4 ISO Base Media File Format with a continuous timeline maintained by inserting additional audio samples.

Claims

1. A system for streaming a media presentation with inserted or edited media content from a server to a client through a network, the system comprising:

a video origin server configured to generate a media presentation for different streaming protocols;

a remix MPEG-4 module configured to generate a MPEG-4 ISO Base Media File Format data from a XML based media playlist; and

a playlist origin, configured to generate the XML based media playlist,

where the video origin server is linked to the remix MPEG-4 module to receive the MPEG-4 ISO Base Media File Format data from the remix MPEG-4 module, and,

where the Remix MPEG-4 Module is linked to the playlist origin as the remix MPEG-4 module receives the XML based media playlist from the playlist origin,

where the video origin retrieves the ISO Base Media File Format that contains a minf box and a dref box minf that each point to a location of a one or more audio and video sources used by the video origin to create the streaming media presentation, and

where the playlist origin generates one or more XML based media playlists that the remix MPEG-4 module then converts to the MPEG-4 ISO Base Media File Format data based on an electronic program guide or by way of rules in a ruleset.

2. The system of claim 1, further comprising of a CDN comprising one or more intermediate cache or configuration proxies, where the client is linked to the video origin server to receive data formatted in the media presentation through the CDN comprising one or more intermediate cache or configuration proxies.

3. The system of claim 1, further comprising a proxy, where the video origin server is linked to the remix MPEG-4 module to receive data formatted in the MPEG-4 ISO Base Media File Format data by way of, or through, the proxy.

4. The system of claim 1, further comprising a playlist proxy where the remix MPEG-4 module is linked to the playlist origin to receive data formatted in the XML based media playlist by way of, or through, the playlist proxy.

8. The system of claim 1, where the minf box is a container box in the MPEG-4 ISO Base Media File Format data that contains the dref box that is a container box in the MPEG-4 ISO Base Media File Format data that contains information about the location of the one or more audio and video sources.

5. The system in 1, where the client requests from a content management system (CMS) a personalized URL for usage to request a personalized manifest for the media presentation with inserted or edited content from the video origin server.

6. The system in 1, where the remix MPEG-4 module generates the MPEG-4 ISO Base Media File Format data with a continuous timeline based on the XML based media playlist.

7. The system in 1, where the remix MPEG-4 module inserts compressed silent audio samples in a MPEG-4 ISO Base Media File Format data to preserve the continuous timeline of the XML based media playlist received from the playlist origin.

9. The system in 8, where the one or more audio and video sources are located in a different location other than the MPEG-4 ISO Based Media File Format data.

10. A method for streaming a media presentation with inserted or edited content between a server and a client through a network, the method comprising the steps of:

generating a media presentation for different streaming protocols by way of a video origin server,

generating MPEG-4 ISO Base Media File Format data from a textual playlist based on an XML based file format by way of a remix MPEG-4 module,

providing or generating playlists in an XML based media playlist including but not limited to Synchronized Multimedia Integration Language (SMIL), that describes the media presentation by way of a playlist origin implemented in hardware or software,

receiving the MPEG-4 ISO Base Media File Format data from the remix MPEG-4 module by way of the video origin server, where the remix MPEG-4 module is linked to the playlist origin as the remix MPEG-4 module receives the XML based media playlist from the playlist origin;

retrieving the MPEG-4 ISO Base Media File Format that contains a minf box and a dref box minf that each point to a location of a one or more audio and video sources used by the video origin to stream the media presentation, and

generating one or more XML based media playlists that the remix MPEG-4 module then converts to the MPEG-4 ISO Base Media File Format data based on an electronic program guide or by way of rules in a ruleset.

11. The method of claim 10, further comprising the step of receiving data formatted in the MPEG-4 ISO Base Media File Format data by way of, or through proxying.

13. The method of claim 10, where the step of generating the MPEG-4 ISO Base Media File Format data from the XML based media playlist by way of a remix MPEG-4 module further performs the steps of:

retrieving the XML based media playlist from the playlist origin; and

generating the ISO Base Media File Format data with a continuous timeline from the XML based media playlist.

14. The method of claim 13, further comprising inserting compressed silent audio samples in the ISO Base Media File Format data to preserve the continuous timeline of the XML based media playlist.

15. The method of claim 14, further comprising:

generating the XML based media playlist for usage by the remix MPEG-4 module; and

converting the XML based media playlist into data formatted in an ISO base media file format.

16. The method of claim 15, further comprising:

composing references to programs in external sources and content in the XML based media playlist including one or more seq tags in the XML based media playlist.

17. The method of claim 13, where the step of retrieving the XML based playlist occurs by way of a proxying via one or more interconnected cache or configuration proxies.

12. The method in 10, further comprising:

requesting from the content management system a personalized URL for usage by a client; and

requesting a manifest for the media presentation with inserted or edited content from the video origin server.
