Abstract:
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.
Abstract:
Systems and methods for performing smooth visual search of media encoded for adaptive bitrate streaming using trick play streams are disclosed. One embodiment of the invention includes requesting and buffering portions of video from at least one of the alternative streams using a playback device, decoding the buffered portions of video using a decoder on the playback device, receiving at least one user instruction directing the playback device to perform a visual search of the media, requesting and buffering potions of video from the trick play stream using the playback device, and decoding the buffered portions of the trick play stream using a decoder on the playback device.
Abstract:
Techniques and mechanisms described herein facilitate the delivery of prioritized side channel data to a client machine. According to various embodiments, base layer data may be transmitted to the client machine. The base layer data may include a plurality of base layer data segments. The base layer data segments may be capable of being used to present a media content item at a first quality level. Side channel data may be transmitted to the client machine. The side channel data may include a plurality of side channel data segments. Each side channel data segment may correspond with a base layer data segment. The side channel data segments may be capable of being combined with the corresponding base layer data segments to present the media content item at second quality level. The second quality level may be being greater than the first quality level.
Abstract:
In an example, a system for distributed video creation is provided. In an example, the system enables users to create the ideas that they and others might film and/or upload. These may be single scene ideas, or multiple scene ideas. These ideas may be as part of a broader, existing video work, or a new video work. These ideas may be manifested as text (such as descriptions or instructions) or verbal (audio), or through pictures or video.
Abstract:
A digital cable broadcast receiver and a method for automatically processing caption data of various standards and types, is disclosed. The digital broadcast receiver includes: a demultiplexer for dividing a received broadcast stream into video data, audio data, supplementary information; a controller for determining whether caption data included in the video data is digital caption data or analog caption data on the basis of caption information included in the supplementary information, and outputting a control signal according to a result of the determining; a digital caption decoder for extracting and decoding digital caption data from the video data according to the control signal; and an analog caption decoder for extracting and decoding analog caption data from the video data according to the control signal.
Abstract:

Abstract:
Techniques are disclosed for automatic static summarization of videos. For example, a method of creating a static summary of a video comprises the following steps. Shots in the video are detected, wherein the detected shots are frames of the video having a correlation. The detected shots are clustered into clusters based on similarity. The clusters of shots are ranked. At least a portion of the shots are selected based on cluster ranking for inclusion in the static summary. The static summary is generated by combining thumbnail images of the selected shots. Prior to the ranking step, the method may further comprise detecting a presence of slides in any of the shots, and the ranking of a given shot is based in part on whether the shot is a slide. By way of example, such static summaries can be shared in emails and in calendar applications.
Abstract:
A method is provided in one example embodiment that includes receiving a plurality of depth values corresponding to pixels of an image; and filtering the image as a function of a plurality of variations in the depth values between adjacent pixels of a window associated with the image. In more detailed embodiments, the method may include encoding the image into a bit stream for transmission over a network. The filtering can account for a bit rate associated with the encoding of the image.
