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.

Methods, systems, and computer readable media for controlling delivery of content are provided. In some embodiments, a system for controlling delivery of content is provided. The system includes processing circuitry configured to: transmit, to a server, a plurality of requests for blocks of the content; while at least some of the plurality of requests are still outstanding: detect a change of a service characteristic of a connection between the system and the server; determine a preferred number of outstanding requests; and cancel at least some of the requests from the plurality that are still outstanding based on the preferred number and a count of the requests from the plurality that are still outstanding.

Systems and methods in accordance with embodiments of this invention provide for encoding and playing back video at different frame rates using enhancement layers. In a number of embodiments, video is encoded using temporal scalability involving the creation of a base layer at a first frame rate and an enhancement layer including additional frames enabling playback at a second higher frame rate. The second higher frame rate can also be referred to as an enhanced frame rate. In a number of embodiments, the base and enhancement layers are stored in one or more container files that contain metadata describing the enhancement layer. Based on the capabilities of a playback device, it can select the particular frame rate at which to playback encoded video.

Systems and methods for encoding alternative streams for use in adaptive bitrate streaming based upon the delay of each stream in accordance with embodiments of the invention are described. One embodiment of the invention includes memory, and a processor configured by a source encoding application to: receive multimedia content, where the multimedia content includes source video data having a primary resolution and a primary sample aspect ratio; and encode the source video data as a set of alternative video streams, where: the alternative video streams have different maximum bitrates; and the alternative video streams are encoded to have an upper bound seek delay that is equal to or less than the upper bound seek delay of streams in the set of alternative video streams that are encoded at a higher maximum bitrate.

Systems and methods for adaptive bitrate streaming of alternative streams of video encoded at resolution and sample aspect ratio combinations and maximum bitrates in accordance with embodiments of the invention are disclosed. In one embodiment of the invention, a source encoder configured to encode a source video stream as a plurality of alternative streams of video for playback on a playback device includes a processor configured to receive multimedia content including source video data having a primary resolution, a primary sample aspect ratio, and a primary frame rate and to encode the source video data as alternative streams of video, where the resolution and sample aspect ratio of at least one of the alternative streams of video are selected to have an aspect ratio that is the same as a predetermined display aspect ratio and at least one of the alternative streams is encoded at a maximum bitrate.

Systems and methods for creating trick play streams for use in adaptive bitrate streaming in accordance with embodiments of the invention are disclosed. One embodiment includes a set of encoding servers that encode source content as a set of streams that are each stored in a separate container file, where the set of streams includes: alternative video streams; an audio stream; and at least one trick play stream. In addition, the trick play stream is encoded at a lower frame rate than the frame rates of the alternative video streams, and each frame of the trick play stream is a picture encoded without reference to another picture in the trick play stream. In addition, the trick play stream is stored in a container file including a trick play index having entries that include a timecode and a location of a frame in the track play stream.
