Abstract: In some embodiments, a method analyzes information regarding a round-trip time where the round-trip time is based on sending a request for a segment of a media program and receiving the segment of the media program. The method determines when to switch from requesting a single segment of the media program to sending a request that requests a plurality of segments of the media program. When switching from requesting the single segment of the media program, the request for the plurality segments of the media program is sent where at least two or more of the segments are received without sending a subsequent request for the two or more segments.

Abstract: In one embodiment, a method selects a first reference block in a first reference frame and a second reference block in a second reference frame. The first reference block and the second reference block are used to predict a current block. The first reference block is selected as an anchor point. Then, the method searches in the second reference frame for a third reference block and determines whether the third reference block is a better reference block than the second reference block for predicting the current block.

Abstract: In some embodiments, a method receives playback information for a plurality of representations based on one or more videos being played at a media player. The plurality of representations have at least one different characteristic that affects playback of the video. A dropped-frame measurement is predicted for the plurality of representations based on the playback information. Then, the dropped-frame measurement is compared to a threshold for the plurality of representations. The method marks a first set of the plurality of representations as not being available based on the comparing. A second set of the plurality of representations are provided to the media player when the media player requests a video for playback and the first set of the plurality of representations for the video are blocked from being requested by the media player.

Abstract: In some embodiments, a method receives a first set of video files at a node that delivers video files to client devices and receives a second set of video files. The second set of video files are predicted to be delivered by the node to a client device during a time period. The node receives a request for a video file from a client device and determines whether the video file is stored in the first set of video files and the second set of video files. When the video file is stored at the node, the node sends the video file from the first set of video files and the second set of video files. When the video file is not stored in the first set of video files and the second set of video files, the node sends a request for the video file to another node.

Abstract: In one embodiment, a method selects a first reference block in a first reference frame and a second reference block in a second reference frame. The first reference block and the second reference block are used to predict a current block in a current frame. A first region is selected based on the first reference block, a second region is selected based the second reference block, and a third region is selected based on the current block. The method compares a characteristic of the first region to a characteristic of the third region and compares a characteristic of the second region to the characteristic of the third region to adaptively determine a first weight for the first reference block and a second weight for the second reference block. Then, a prediction block is calculated for the current block using the first weight and the second weight.

The method processes a first sub-partition in the plurality of sub-partitions using the first set of reference pixels and a second sub-partition in the plurality of sub-partitions using the first set of reference pixels in parallel. Then the method processes a third sub-partition in the plurality of sub-partitions based on a second set of reference pixels determined from the processing of the first sub-partition and processing a fourth sub-partition in the plurality of sub-partitions based on a third set of reference pixels determined from the processing of the second sub-partition.

Abstract: In some embodiments, a method sends a first frame that establishes a first state to push information to a client in a stream based on a first set of characteristics. The method transitions from the first state to a second state that allows pushing of content to the client. Content is pushed for a first time window to the client based on the first set of characteristics without receiving a request for the content in the first time window. The method receives a request to change the first set of characteristics to a second set of characteristics. The request includes information requesting a switch from the second state to the first state. In response to receiving the change, the method sends a second frame to continue pushing content to the client in the stream based on the second set of characteristics and transitions from the second state to the first state.

Abstract: In some embodiments, a method determines a combination of sub-bitstream chunks from a plurality of sub-bitstreams for a video. The combination of sub-bitstream chunks includes a quality measurement. The method exchanges a sub-bitstream chunk in the combination of sub-bitstream chunks with another sub-bitstream chunk from another sub-bitstream in the plurality of sub-bitstreams based on a relationship of a change in bitrate to a change in quality due to the exchanging.

Abstract: In one embodiment, a method receives a first chunk in a plurality of chunks from a video. The plurality of chunks are sent to a plurality of transcoding units for transcoding in parallel. The method transcodes the first chunk at a first transcoding unit to generate a first transcoded sub-bitstream. Then, first statistical information is received from one or more second chunks being transcoded by other transcoding units. The first statistical information from the one or more second chunks is compared to second statistical information from the first chunk and it is determined whether to perform a second transcoding process based on the comparing. When the second transcoding process is to be performed, the method performs the second transcoding process with the first chunk to generate a second transcoded bitstream and outputs the second transcoded bitstream. When the second transcoding process is not to be performed, the method outputs the first transcoded sub-bitstream.

Abstract: In one embodiment, a method determines if a first flag for using a most probable mode (MPM) set for intra prediction is set. When the first flag indicates the MPM set is used, the method decodes a first index for the MPM, the first index indicating a first intra prediction mode in the MPM set. When the first flag does not indicate the MPM set is being used, the method determines if a second flag for using a near-MPM set is set. When the second flag indicates the near-MPM set is being used, the method decodes a second index for the near-MPM, the second index indicating a second intra prediction mode in the near-MPM set. When the second flag does not indicate the near-MPM is being used, the method decodes a third index for a non-MPM, the third index indicating a third intra prediction mode in the non-MPM set.

Abstract: In some embodiments, a method receives sub-bitstreams from a multi-pass transcoding process of a video. A target quality is received based on a characteristic of transcoding of the video. Then, the method generates a combination of sub-bitstream chunks from the sub-bitstreams for the video. A set of exchange rates is calculated where each exchange rate defines how much bitrate will be reduced in relation to quality if an anchor sub-bitstream chunk from the combination of sub-bitstream chunks is replaced with another sub-bitstream chunk from other sub-bitstreams. Then method iteratively exchanges one of the anchor sub-bitstream chunks in the combination of sub-bitstream chunks with another sub-bitstream chunk based on the exchange rate of the anchor sub-bitstream chunk in the combination of sub-bitstream chunks until the quality measurement of the combination meets the target quality. Then, the combination of sub-bitstream chunks is recorded as a transcoded bitstream.
