    摘要: Systems, devices and methods for adaptive switching in multicast media streams are disclosed herein. In an embodiment, a method for adaptively transmitting content to one or more users based on currently available bandwidth via internet protocol (“IP”) multicast protocol, includes: receiving a first content stream having a plurality of data packets, the first content stream encoded at a first bit rate; receiving a second content stream having a plurality of data packets, the second content stream encoded at a second bit rate, wherein the first bit rate is different than the second bit rate and wherein the first and second content streams represent the same content; transmitting the first content stream to a user; determining that the user could receive the second content stream based on available bandwidth for transmitting data to the user; and transmitting the second content stream to the user.

    摘要: In embodiments of algorithmic media stream selection, a media routing device (120) receives media content (106) from a content distributor (202) and streams the media content to a media playback device (122). The media routing device can receive a request for a media content stream (110) from the media playback device, and select a substitute media content stream (112) for distribution to the media playback device based on one or more variable parameters. The media routing device then forwards the request to the content distributor for the substitute media content stream, and receives the substitute media content stream from the content distributor. The media routing device is implemented to then identify the substitute media content stream as the requested media content stream, and communicate the substitute media content stream to the media playback device for playback as the requested media content stream.

    摘要: A content delivery system and method that receives a request for a content stream that includes splice points. The method receives a playlist that includes an ordered list of media segment files that represent the content stream, and splice point tags, where generation of the media segment files aligns segment boundaries with the splice points in the content stream, and where each splice point tag is in a location in the playlist that corresponds to the position of one of the splice points in the content stream. The method identifies an insertion position in the playlist based on the location of the splice point tags, selects an advertisement segment, inserts the advertisement segment at the insertion position to create a modified playlist, removes the splice point tags from the modified playlist, and sends the modified playlist to the video display device.
