Method to insert program boundaries in linear video for adaptive bitrate streaming
Aspects of the subject disclosure may include, for example, a system for indicating a program boundary in an adaptive bitrate media stream, where the system includes a memory and a processor that performs operations including generating multiple transcoded media output streams of different bit rates from an input linear media stream, fragmenting the multiple transcoded media output streams into chunks, detecting a program boundary in the input linear media stream, and supplying a program change indicator in a manifest file for implementing program change features in mobile communication devices. Other embodiments are disclosed.
Systems and methods for player input motion compensation by anticipating motion vectors and/or caching repetitive motion vectors
Systems and methods for reducing latency through motion estimation and compensation techniques are disclosed. The systems and methods include a client device that uses transmitted lookup tables from a remote server to match user input to motion vectors, and tag and sum those motion vectors. When a remote server transmits encoded video frames to the client, the client decodes those video frames and applies the summed motion vectors to the decoded frames to estimate motion in those frames. In certain embodiments, the systems and methods generate motion vectors at a server based on predetermined criteria and transmit the generated motion vectors and one or more invalidators to a client, which caches those motion vectors and invalidators. The server instructs the client to receive input from a user, and use that input to match to cached motion vectors or invalidators. Based on that comparison, the client then applies the matched motion vectors or invalidators to effect motion compensation in a graphic interface. In other embodiments, the systems and methods cache repetitive motion vectors at a server, which transmits a previously generated motion vector library to a client. The client stores the motion vector library, and monitors for user input data. The server instructs the client to calculate a motion estimate from the input data and instructs the client to update the stored motion vector library based on the input data, so that the client applies the stored motion vector library to initiate motion in a graphic interface prior to receiving actual motion vector data from the server. In this manner, latency in video data streams is reduced.
System and method for sending and rendering an image by a device based on receiver's context
A system and method for sending an image to a user device based on the context of a user of the device are provided. An image to be sent to a user device may be obtained. The context of the user may be determined. The image may be analyzed to detect and prioritize objects in the image based on the context of the user. The image may be encoded such that objects are rendered on the user device in an order based on the prioritization. The encoded image may be sent to the user device.
Method and apparatus for processing webpage, device, and storage medium
The present application provides a method and an apparatus for processing webpage, a device and storage medium, involving the terminal vision technology. The specific implementation is: when a server determines that a current network meets a preset condition and a webpage to be displayed includes an image required to be displayed, the server sends a static data resource corresponding to the image required to be displayed to the terminal. The preset condition includes at least one of the following: the current network being a mobile network, a bandwidth of the current network being less than a preset bandwidth, and a rate of the current network being less than a preset rate. Therefore, it is unnecessary to send a static data resource corresponding to an image not required to be displayed to the terminal, thereby reducing a traffic consumption and at the meanwhile, improving an integrity and coherence of the webpage.
Uplink and downlink streaming bit rate assistance in 4G and 5G networks
Various embodiments may provide streaming service downlink network assistance and/or uplink network assistance mechanisms in a fifth generation (5G) system (5GS) network via an Application Function (AF) computing device in a 5GS. In some embodiments, a computing device and/or the AF computing device may inform the network about needs for capacity for downlink or uplink traffic. Various embodiments may include sending radio access network (RAN) capacity requests to a network computing device of the 5GS network including a 5G RAN. In some embodiments, the network computing device of the 5GS network may be a computing device that is not part of the 5G RAN. In some embodiments, capacity need messages may be sent directly from user equipment (UE) computing devices to computing devices of the 5G RAN. In some embodiments, capacity information of the RAN may be delivered to an AF computing device via an intermediate network function.
Method, apparatus, and device for determining quality of audio and video stream, and computer-readable storage medium
A method for determining quality of an audio and video stream includes: obtaining a key indicator for a target audio and video stream, the key indicator including at least one of the following indicators within a reference time period: a maximum quantity of continuously lost packets, an average packet receiving time interval, an average packet receiving time interval variance, or a quantity of stream interruptions; and determining a QoE of the target audio and video stream based on the key indicator.
Eye contact prompting communication device
A communication device, method, and computer program product prompt correct face/eye positioning to enable perceived eye-to-eye contact of a user of a video capturing device with camera on a same device side as the viewable display device. A first communication device includes a first display device having a first graphical user interface (GUI). A first image capturing device of the first communication device has a field of view that captures a face of a first user viewing the first GUI. The first image capturing device generates a first image stream of the field of view. A controller of the communication device identifies a look target area of the first GUI proximate to the first image capturing device. The controller presents visual content on the first GUI within the look target area to prompt the first user viewing the first GUI to look towards the look target area.
Image compression and decompression
Embodiments include methods for image compression and decompression. A sending computing device may determine a type of packing used for a chunk of image data, generate metadata describing the type of packing used for the chunk of image data, pack the chunk of image data according to the determined type of packing, and send the packed chunk of image data and the metadata to a second computing device. A receiving computing device may decode the metadata describing the type of packing used for the chunk of image data, determine the type of packing used for the chunk of image data based on the decoded metadata, and unpack the chunk of image data according to the determined type of packing used for the chunk of image data.
