摘要： Systems and methods for processing a live video stream are provided. An ingestion component receives segments of a live video stream in association with a request to process the live video stream. A control component generates an instruction graph for the live video stream based on predetermined criteria. The instruction graph defines a workflow for processing the live video stream, the workflow comprising a set of services for processing the segments. A transcoding component employs a subset of the services to process the segments based at least in part on the instruction graph and a distribution component then streams the segments to a device in response finishing process of the segments. With the live video processing system, segments of a video stream are processed and distributed as they are received. Thus segments of the video stream are processed and distributed prior to processing of the entire video stream.

摘要： A system and method for a live streaming platform that can redundantly process input streams in parallel ingestion pipelines is disclosed herein. Ingested input streams in the parallel pipelines can be segmented using a segmentation function that creates identical segments in each of the streams in the pipelines. If errors occur, or there are disruptions in one or more of the input streams or pipelines, the live streaming platform can ensure that segments are identifiable and different parts of the pipelines can join a main stream at different points in time without disruption.

摘要： In one embodiment, a method includes accessing data identifying a video for processing and mapping an instruction graph to the video based on one or more predetermined criteria and the data identifying the video. The instruction graph describes a workflow for processing the video, and the workflow includes a series of services that each provide particular processing of the video. The method includes calling the services in series to process the video based on the instruction graph. The video streams to each service in series as the video processes. A downstream service may begin processing one or more portions of the video after an upstream service has finished processing the one or more portions of the video and before the upstream service has finished processing the video in its entirety.

摘要： A system and method provides transcoding a video in parallel by multiple transcoders based on a measure of video coding complexity (VCC). The system has a video pre-processing module, a master transcoder, a transcoding controller and multiple transcoders. The video pre-processing module transcodes a source video into an intermediate video. The master transcoder partitions the intermediate video into multiple transcoding units, where a transcoding unit identifies a portion of data of the intermediate video for transcoding. The master transcoder further generates a transcoding request for each transcoding unit. The transcoding controller distributes the transcoding units to the multiple transcoders, which transcode the data of the transcoding units in parallel into transcoded data.

摘要： A system and method for a live streaming platform that can redundantly process input streams in parallel ingestion pipelines is disclosed herein. Ingested input streams in the parallel pipelines can be segmented using a stable segmentation function that creates identical segments in each of the streams in the pipelines. If errors occur, or there are disruptions in one or more of the input streams or pipelines, the live streaming platform can switch between the input streams on a per segment basis to provide reliable streaming feeds to a content distribution network. A master stream can be constructed from each of the master segments per a time period based on a reliability of each of the input streams and segments. Practicing pipeline affinity by selecting subsequent master segments from the same pipeline can minimize glitches.

摘要： A system for synchronizing data streams meant to be displayed concurrently at an end station, but delivered by separate delivery networks is disclosed. In one aspect, apparatus and methods for marking one of the data streams relative to the other are taught, including insertion of frame numbers in vertical and horizontal blanking intervals, the numbers referring to frames in the other stream and related to timing markers, and inserting such numbers by pixel data alteration. In another aspect, apparatus and methods are taught for receiving and re-synchronizing the data streams at a delivery point, including decoding of the relationship data inserted in one data stream referring to the other data stream. Re-synchronization is accomplished by controlling the separate data streams in separate buffer pipelines by a single controller. In a preferred embodiment one data stream is a live video data stream and the other is an annotation stream having added material to be displayed with the live video data stream.

摘要： A system for providing video processing feedback to content providers uploading a video file. As the content provider uploads a video file to the video processing server, the server processes the uploading file and extracts representative video frames from the video file. The video processing server embeds the representative frames into a processing feedback page hosted on a web server in the video processing server. Each representative frame in the feedback page represents a part of the uploading video. The feedback page is accessible through the content provider's browser and the feedback page includes a sequence of representative frames in temporal order. In one embodiment, the representative frames in the feedback page are colored or shaded to indicate whether the video part represented by a particular frame has been processed.

摘要： An automated video editing and indexing system is taught which has application for such tasks as creating a presentation for a video magazine and processing collections of video material in general. The system extracts text either from closed captions (CC) contained in the analog video presentation, or extracted from the voice contained in the presentation by voice-to-text techniques, time-stamps the CC text in text files according to position in the video presentation, and digitizes the video presentation. The text files and digitized video are sent to an editing station, where the CC text is analyzed using Natural Language Processing and other techniques to determine topic changes in the presentation. Keyframes are selected to represent the topic changes, and become thumbnails useful in indexing; indexing meaning marking the video material at points of topic changes, and in some cases jumping the video presentation to the positions represented by the thumbnails. In some cases selected CC text is associated with the thumbnails, and displayed in the video magazine as each thumbnail is selected by mouseover.
