摘要： Systems and methods for adaptive bitrate streaming of media stored in Matroska container files utilizing Hypertext Transfer Potocol (HTTP) in accordance with embodiments of the invention are disclosed. In one embodiment, a processor configured, via a client application, to request portions of files from a remote server. In addition, the client application further configures the processor to retrieve top level index data that identifies a plurality of EBML container files and describes at least a maximum bitrate of the alternative streams contained within the EBML container files, parse the top level index data to obtain information identifying the plurality of EBML container files, request a portion of at least one of the EBML container files that contains the at least one element that specifies the encoding parameters of the stream contained within the EBML container file, retrieve an index that references each element containing portions of encoded video within at least one of the EBML container files, utilize the index to request portions of a first EBML container file that includes elements that contain portions of encoded video, receive and buffer the requested elements, decode the encoded video contained within the buffered elements utilizing the encoding parameters, measure current streaming conditions, and select another of the EBML container files from which to retrieve elements containing portions of encoded video for decoding, where the selection is based upon the measured streaming conditions and the description of the bitrate of the alternative stream contained within the top level data.

摘要： A method of adaptive bitrate streaming of media comprises:
transcoding source media as a number of alternative streams, where the alternative streams are streams that encode the same media content at different bitrates;
generating a top level index file when a playback device (200) requests the commencement of playback of the source media, where the top level index file identifies a plurality of container files containing the streams and at least a plurality of the streams are the alternative streams; and
enabling retrieval of the top level index file by the playback device (200) so that it can utilize the information in the top level index file to retrieve encoded media from the plurality of container files according to the streaming conditions experienced by the playback device.

摘要： Systems and methods for performing trick play functionality using trick play streams during adaptive bitrate streaming in accordance with embodiments of the invention are disclosed. One embodiment includes requesting a video container index from a video container file containing a video stream from a plurality of alternative streams of video; requesting at least one portion of the video stream using at least one entry from the video container index; decoding the at least one portion of the video stream; receiving at least one user instruction to perform a visual search of the media; requesting a trick play container index from a trick play container file containing a trick play stream; requesting at least one frame of video from the at least one trick play stream; and decoding and displaying the at least one frame of video from the trick play stream.
