ON DEMAND DISPLAY SOURCE PRESENTATION AT A PARTIAL DISPLAY AREA
20230081535 · 2023-03-16 · ·

A display presents picture-in-picture and/or picture-by-picture formatted visual information initiated by secondary information handling systems while the display presents primary visual information. The display broadcasts plural partial video buffer definitions to plural information handling systems that can selectively initiate network sessions to present visual images in areas of the display by storage of visual image information in a portion of the display video buffer. The secondary display area may present visual images for IoT or similar headless devices having relevance to an end user of a primary information handling system.

SYSTEMS AND METHODS FOR ADAPTIVELY BUFFERING MEDIA CONTENT AT A DIGITAL VIDEO RECORDER
20230127385 · 2023-04-27 ·

Systems and methods are disclosed herein for adaptively buffering content of a media asset from a media source when a different media asset from a different media source is being played at user equipment. The media guidance application may predict when and which channel or other media source the user is likely to switch to and then buffer content from the predicted channel or other media source accordingly. The pre-tuning buffering may enhance the user experience by reduce tuning latency when the user switches channels.

Reference Picture Management in Video Coding
20230128843 · 2023-04-27 ·

A method for storing a coded video bitstream. The method includes obtaining the coded video bitstream and storing the coded video bitstream in at least one storage medium. The coded video bitstream includes a first reference picture list syntax structure and a second reference picture list syntax structure. Each reference picture list syntax structure contains a number of entries. A first reference picture list of a current slice and a second reference picture list of the current slice are derived based on the first reference picture list syntax structure and the second reference picture list syntax structure. The first reference picture list and the second reference picture list are derived for bitstream conformance checking instead of for decoding a current picture or pictures following the current picture in decoding order when the current slice comprises an intra (I) slice of a non-intra random access point (IRAP) picture.

Audio splicing concept

Audio splicing is rendered more effective by the use of one or more truncation unit packets inserted into the audio data stream so as to indicate to an audio decoder, for a predetermined access unit, an end portion of an audio frame with which the predetermined access unit is associated, as to be discarded in playout.

Method and apparatus for managing over-the-top video rate

Aspects of the subject disclosure may include, for example, a device including a processing system including a processor and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, including monitoring network traffic to determine a transmission control protocol traffic pattern, determining a target video rate from the transmission control protocol traffic pattern, and modifying an over-the-top video delivery service network according to the target video rate. Other embodiments are disclosed.

To enable satisfactory decoding processing corresponding to a decoding capability on a reception side. Image data of pictures constituting moving image data are sorted into multiple hierarchies, image data of pictures of each of the sorted hierarchies are encoded, and video data including the encoded image data of the pictures of each of the hierarchies is generated. A container of a predetermined format including the video data is transmitted. The multiple hierarchies are divided into a predetermined number of hierarchy groups, the predetermined number being two or more, and identification information for identifying a hierarchy group to which encoded image data of each picture included in the video data belongs is inserted into a packet as a container of the video data.

Systems and methods for performing adaptive bitrate streaming

Systems and methods for performing trick play functionality using trick play streams during adaptive bitrate streaming in accordance with embodiments of the invention are disclosed. One embodiment includes requesting a video container index from a video container file containing a video stream from a plurality of alternative streams of video; requesting at least one portion of the video stream using at least one entry from the video container index; decoding the at least one portion of the video stream; receiving at least one user instruction to perform a visual search of the media; requesting a trick play container index from a trick play container file containing a trick play stream; requesting at least one frame of video from the at least one trick play stream; and decoding and displaying the at least one frame of video from the trick play stream.

Electronic apparatus and control method thereof

An electronic apparatus includes: a display; a communication circuit configured to communicate with an external apparatus; and a processor. The processor is configured to: transmit, to the external apparatus, a request to receive information on a screen which is currently displayed on the external apparatus, receive, from the external apparatus, a response corresponding to the request, based on the response, identify a number of contents displayed in the screen, based on identifying that a plurality of contents is displayed in the screen, display a UI on the display for selecting one among the plurality of contents, in response to a content, among the plurality of contents, being selected by a user input through the UI, transmit a signal indicating the selected content to the external apparatus, and receive, from the external apparatus, data corresponding to the content to display an image on the display.

Real-time latency measurement of video streams

Frames of a video stream collected at first and second points along a video delivery chain are buffered into first and second buffers, respectively, the second point being downstream the video delivery chain from the first point. A control group is identified as a subset of frames of the second buffer. Correlations of extracted features of the control group to extracted features of successive windows of frames of the first buffer are computed, the extracted features being based on spatial information and temporal information of the video stream. A delay between the video stream collected at the first point and the video stream collected at the second point is identified according to a maximum correlation of the correlations.

Cellular communication protocol aware multimedia streaming

A device implementing cellular communication protocol aware multimedia streaming may include at least one processor configured to establish a link for communicating with another device, wherein the link utilizes at least one of a first cellular communication protocol or a second cellular communication protocol. The at least one processor may be configured to determine a bit rate for a video stream to be provided to the other device based at least in part on whether the link utilizes the first cellular communication protocol or the second cellular communication protocol, wherein a first bit rate is determined when the link utilizes the first cellular communication protocol and a second bit rate is determined when the link utilizes the second cellular communication protocol. The at least one processor may be configured to provide, for transmission over the link to the other electronic device, the video stream at the determined bit rate.
