20150334386 | AUTOMATIC VIDEO COMPARISON OF THE OUTPUT OF A VIDEO DECODER - The automatic video comparison system for measuring the quality of decoded data described herein provides a method for measuring the quality of decoded data at the level of sub-units of a unit of data, for instance at the level of sub-blocks of a video frame. The system can therefore locate defects that may not otherwise be detected by an automated system that measures quality at the level of the entire frame. Processing encoded media is computationally intensive, thus the automatic video comparison system uses a distributed computing system in order to distribute the computations across many compute resources that are capable of operating in parallel. | 11-19-2015 |
20150312644 | HYBRID RESOURCE MANAGEMENT SYSTEM AND METHOD - A method of optimizing the delivery of content over a content delivery network to client devices in accordance with optimization rules is provided.

20150312594 | ERROR RECOVERY FOR VIDEO DELIVERY VIA A SEGMENTATION PROCESS - A client device may receive encoded video via a transport stream based on a video coding protocol. When errors result in receiving the encoded video, the client device may use an Internet Protocol (IP) connection to recover from the error. For example, an encoder may insert markers inband in the transport stream, and a segmenter then segments the video using the markers. The content remains in the form of a continuous transport stream that is compatible with existing transport stream delivery mechanisms. When an error occurs, the client device can then determine a locator for a segment that can be used to recover from the error and requests the segment from a server through the IP connection. The server sends the segment to the client device at the level of the transport stream layer without adding another protocol layer to encapsulate the segment. | 10-29-2015 |
