Patent number: 11088788Abstract: A video encoding device (e.g., a wireless transmit/receive unit (WTRU)) may transmit an encoded frame with a frame sequence number using a transmission protocol. The video encoding device, an application on the video encoding device, and/or a protocol layer on the encoding device may detect a packet loss by receiving an error notification. The packet loss may be detected at the MAC layer. The packet loss may be signaled using spoofed packets, such as a spoofed NACK packet, a spoofed XR packet, or a spoofed ACK packet. A lost packet may be retransmitted at the MAC layer (e.g., by the encoding device or another device on the wireless path). Packet loss detection may be performed in uplink operations and/or downlink operations, and/or may be performed in video gaining applications via the cloud. The video encoding device may generate and send a second encoded frame based on the error notification.Type: GrantFiled: March 28, 2014Date of Patent: August 10, 2021Assignee: VID SCALE, Inc.Inventors: Weimin Liu, Rahul Vanam, Liangping Ma, Yuriy Reznik, Gregory S.

Patent number: 10932152Abstract: Systems, methods, and instrumentalities are disclosed to perform rate adaptation in a wireless transmit/receive unit (WTRU). The WTRU may receive an encoded data stream, which may be encoded according to a Dynamic Adaptive HTTP Streaming (DASH) standard. The WTRU may request and/or receive the data stream from a content server. The WTRU may monitor and/or receive a cross-layer parameter, such as a physical layer parameter, a RRC layer parameter, and/or a MAC layer parameter (e.g., a CQI, a PRB allocation, a MRM, or the like). The WTRU may perform rate adaption based on the cross-layer parameter. For example, the WTRU may set the CE bit of an Explicit Congestion Notification (ECN) field based on the cross-layer parameter. The WTRU may determine to request the data stream encoded at a different rate based on the cross-layer parameter, the CE bit, and/or a prediction based on the cross-layer parameter.Type: GrantFiled: May 6, 2019Date of Patent: February 23, 2021Assignee: VID SCALE, Inc.Inventors: Anantharaman Balasubramanian, Gregory S.

Patent number: 10880349Abstract: Quality-based optimizations of a delivery process of streaming content may be enabled. The optimization may take the form of quality-based switching. To enable quality-based switching in a streaming client, the client may have access to information about the quality of an encoded segment and/or sub-segment. Quality-related information may include any number of added quality metrics relating to an encoded segment and/or sub-segment of an encoded video stream. The addition of quality-related information may be accomplished by including the quality-related information in a manifest file, including the quality-related information in segment indices stored in a segment index file, and/or providing additional files with quality-related segment information and providing a link to the information from an MPD file. Upon receiving the quality-related information, the client may request and receive a stream that has a lower bitrate, thereby saving bandwidth while retaining quality of the streaming content.Type: GrantFiled: November 13, 2018Date of Patent: December 29, 2020Assignee: VID SCALE, Inc.Inventors: Yuriy Reznik, Eduardo Asbun, Zhifeng Chen, Rahul Vanam

Publication number: 20200358835Abstract: A fault-tolerant, cloud-based system can comprise a redundancy control unit capable of switching between transcoded video streams output by two or more transcoders. The redundancy control unit outputs a manifest from one of the transcoded streams and, upon detecting a fault in the stream, can modify the manifest to switch to another of the transcoded video streams. The redundancy control unit can further modify the manifest to flag the discontinuity in the video stream, which allows the player to switch to the new transcoding video stream without error. Other embodiments can include additional redundancies to help provide additional fault tolerance.Type: ApplicationFiled: May 8, 2020Publication date: November 12, 2020Applicant: Brightcove Inc.Inventors: Jorge Cenzano Ferret, Ted Krofssik, Matthew Neil, Michael Harty, Yuriy Reznik

Patent number: 10511991Abstract: Systems and methods are provided for adapting communication parameters to a variety of link conditions, traffic types and priorities. For example, WiFi transmission parameters (e.g. retry limit, AIFS, CW size, MCS order and/or CCA threshold) may be adapted to channel congestion levels, channel errors and/or traffic priority levels. Parameter adaptation may be coordinated across layers (e.g. between MAC and PHY layer parameters). Congestion levels may be detected, for example, using a smoothed queue size and/or channel busy time. Traffic may be transmitted using adapted parameters, such as reduced retry limits for a high congestion level and increased retry limits for priority traffic in response to channel error. Feedback may support parameter adaptation. For example, feedback may be provided by a receiver and/or within a sender, such as a sender MAC and/or PHY layer or a parameter adapter providing feedback (e.g. spoofed NACK packet) to a sender application, transport and/or network layer.Type: GrantFiled: May 17, 2019Date of Patent: December 17, 2019Assignee: VID SCALE, INC.Inventors: Liangping Ma, Wei Chen, Gregory S.
