Embodiments of this application provide a projection display method and an electronic device, and relate to the field of terminal technologies, to dynamically adjust, based on a quantity of source devices, a parameter of display data projected onto a destination device, so as to improve display smoothness and use experience of a user during projection. The method includes: A source device sends a projection instruction to a destination device, where the projection instruction is used to instruct to project a display interface of the source device onto the destination device for display. The source device receives a first broadcast sent by the destination device, where the first broadcast includes a quantity N of source devices that need to perform projection onto the destination device for display. The source device negotiates a first projection parameter with the destination device based on the quantity N of the source devices, where the first projection parameter includes one or more of a projection resolution, a transmission bit rate, or an encoding compression rate. The source device sends first display data to the destination device based on the first projection parameter.

The present application provides a video frame transmission method, apparatus, electronic device, and readable storage medium, and relates to the field of Internet of Vehicles, comprising: transmitting a first video frame of a target video to a target device at a reference frame rate; acquiring time delay of the first video frame; determining, according to the time delay, target frame rate of a second video frame to be transmitted in the target video; transmitting the second video frame to the target device at the target frame rate. By dynamically adjusting the transmission frame rate of the video frame in the method, the time delay of the video frame from creation to display on the target device is reduced, thereby ensuring the presentation effect of the video on the target device.

Systems and methods are operable to control presentation of an erotica-related media content event. An exemplary embodiment is a media device that receives information from a user sensor that is configured to sense a physical characteristic of a user viewing the erotica-related media content event, and automatically changes presentation of the erotica-related media content event based on the received information corresponding to the sensed physical characteristic of the viewing user.

An image data of pictures constituting moving image data is encoded to generate an encoded video stream. In this case, the image data of the pictures constituting the moving image data is classified into a plurality of levels and encoded to generate a video stream having the image data of the pictures at the respective levels. Hierarchical composition is equalized between a low-level side and a high-level side, and corresponding pictures on the low-level side and the high-level side are combined into one set and are sequentially encoded. This allows a reception side to decode the encoded image data of the pictures on the low-level side and the high-level side with a smaller buffer size and a reduced decoding delay.

Method (1000) of providing power saving information for media content is described including receiving (1010) media content comprising a plurality of media segments, determining (1020) a power consumption indicator for a media segment of the plurality of media segments, determining (1030) power saving information for the media segment based on the power consumption indicator for the media segment and providing (1040) the power saving information. Method (1100) of receiving power saving information for media content is described including receiving (1110) power saving information for a media segment in a media content, applying (1120) said power saving information to the media segment to generate a power adjusted media content and providing (1130) the power adjusted media content. Equivalent apparatuses for providing (110, 200) and for receiving (120, 200, 250) power saving information for media content are also provided.

A method for managing HTTP adaptive streaming of digital content within a real-time multimedia stream player terminal, associated with a terminal for rendering the digital content. The method includes obtaining a description file for the digital content, including a list of time segments of the content each associated with a plurality of content encoding rates; and downloading time segments at one of the encoding rates. The method implements a concomitant rendering, by the rendering terminal, of the digital content and of an element, called main element, belonging to a group including a menu and other digital content. The method implements, during the downloading step, a partial downloading of a preliminary portion of at least some of the time segments, and a rendering, for a duration of one of the time segments, of a picture decoded from the preliminary portion of the corresponding time segment.

The present document discloses a method for playback of media content via a delivery channel. The delivery channel may generally refer to the channels through which audio or video programs are delivered (transmitted) to the user (receiver). The media content may generally comprise consecutive media programs. In particular, for a specific media program within the media content, a respective content type for that specific media program is also provided. The method may comprise receiving an indication of the sensitivity of a media program to playback latency. The method may further comprise receiving at least a portion of the media program. The method may yet further comprise adapting the playback of the media program based on the indication of its sensitivity to playback latency.

Techniques are disclosed for recognizing aspect ratio errors in image frames of a video and reporting the same. An aspect ratio checker application receives a video that includes multiple image frames and identifies aspect ratio changes in those image frames using a first differential of a time series that includes determined positions of the top, bottom, left, and right of content regions within the image frames. In particular, the aspect ratio checker may identify aspect ratio changes based on non-zero points of the first differential, and the aspect ratio checker further determines aspect ratios of content regions within image frames corresponding to the non-zero points of the first differential. In addition, the aspect ratio checker may generate and display a report indicating the determined aspect ratios and image frame ranges associated with those aspect ratios.
