Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Systems and methods can facilitate identifying 2D content in media that is suitable for conversion into 3D content, and converting the suitable 2D content into 3D content. The identifying can be based on quality criteria applied to the 2D content. For 2D content converted into 3D content, a user can be offered a choice between viewing the content in its original 2D form, or viewing the content in its converted, 3D form. The systems and methods can thereby provide users with greater choice of content and an enhanced viewing experience.
