20090300692 | SYSTEMS AND METHODS FOR VIDEO STREAMING AND DISPLAY - For display of, at a user device, a region of interest within video images and associated applications. In a particular example embodiment, a streaming video source provides streaming data to a user device, with the streaming data being representative of a sequence of images, and each image including a plurality of individually decodable slices. At the user device and for a particular image and a corresponding subset region of the image, less than all of the plurality of individually decodable slices are displayed in response to a current input indicative of the subset region. Future input indicative of a revised subset region is then predicted in response to images in the image sequence that have yet to be displayed and to previously received input. In other embodiments, multicasting methods, systems or arrangements provide streaming video to one or more user devices. | 12-03-2009 |

A buffer map of the node is created at the node, wherein the buffer map lists the packets that have been received and an available bandwidth of the node. The node is connected with at least one neighboring node. The buffer map of the node is exchanged with a buffer map of the at least one neighboring node. Provided a determination is made that at least one packet in the sub stream of the streaming data was not received at the node, the at least one packet is pulled from the at least one neighboring. | 04-14-2011 |

20140201289 | NOTIFICATION FEED ACROSS MULTIPLE CLIENT DEVICES - Event notifications can be provided to a user across multiple client devices or platforms. If a user takes action on one device, notifications on all devices can be updated to reflect the action. For example, notifications can be indexed by topic and time sequence (or other sequence), and multiple notifications related to the same topic can be consolidated at a server or the client so that current information can be presented to the user. | 07-17-2014 |
20140237019 | SERVER-SIDE TRANSCODING OF MEDIA FILES - The disclosed embodiments relate to a file-communication system that enables a user to stream high-quality media (for example, from their Dropboxâ„¢) During operation, the system streams the media at an initial quality level to a client via a channel. For example, the quality level may be one of a set of quality levels associated with different transcoding operations. Then, the system determines or obtains an indicator of performance for the channel. Based on the indicator, the system spawns an additional transcoding operation at a different quality level than is available in the set of quality levels. The resulting media at the different quality level is then streamed from the system to the client via the channel. | 08-21-2014 |
20150237090 | STREAMING OF VARIABLE LENGTH CONTENT SEGMENTS - A content management system streams variable length segments of content items to client devices. The content management system stores a content item and makes the item available for access by one or more client devices. When a client device requests the content item from the content management system, the content management system sends the content item to the device by streaming the content item in segments. Specifically, the content management system partitions the content item into a sequence of variable length segments. An initial portion of the sequence includes rapid start segments that are configured as being the smallest segments in length from the sequence. A subsequent portion of the sequence includes the remaining segments having longer length(s). The content management system streams the segments to the client device in sequential order and in a streaming format. | 08-20-2015 |
20150237102 | PRE-TRANSCODING CONTENT ITEMS - A content management system pre-transcodes portions of content items provided for storage. When a content item is uploaded to the content management system for storage, the content management system stores the content item in an original format. The content management system transcodes a portion of the content item from the original format to a streaming format. The content management system stores the transcoded portion and makes the content item available for access. When a client device requests the content item from the content management system, the content management system first sends by streaming to the client device the stored transcoded portion in the streaming format. During the sending of the transcoded portion, the content management system transcodes a remainder of the content item that has not been transcoded to the streaming format. The content management system sends the transcoded remainder of the content item to the client device. | 08-20-2015 |
