A processor-implemented method in a digital media player includes receiving data defining a user's viewport in relation to spherical video frames displayed by the digital media player; and where a forced perspective event is to be triggered at the time of display of a spherical frame, triggering the forced perspective event conditionally based at least on the orientation of the user's viewport in relation to the spherical video frames. A digital media player includes processing structure for receiving data defining a user's viewport in relation to spherical video frames displayed by the digital media player; and processing structure for, where a forced perspective event is to be triggered at the time of display of a spherical frame, triggering the forced perspective event conditionally based at least on the orientation of the user's viewport in relation to the spherical video frames. A processor-readable medium embodying a computer program for a digital media player is provided. The computer program includes program code for receiving data defining a user's viewport in relation to spherical video frames displayed by the digital media player; and program code for, where a forced perspective event is to be triggered at the time of display of a spherical frame, triggering the forced perspective event conditionally based at least on the orientation of the user's viewport in relation to the spherical video frames.

The present disclosure relates to methods and systems for providing a multi-perspective augmented reality experience. A volumetric video of a three-dimensional space is captured. The volumetric video of the three-dimensional space includes a volumetric representation of a first user within the three-dimensional space. The volumetric video is displayed by a display device worn by a second user, and the second user sees the volumetric representation of the first user within the three-dimensional space. Input indicative of an interaction (e.g., entering or leaving) of the second user with the volumetric representation of the first user is detected. Based on detecting the input indicative of the interaction, the display device switches to a display of a recorded perspective of the first user. Thus, by interacting with a volumetric representation of the first user in a volumetric video, the second user views the first user's perspective of the three-dimensional space.

Systems and methods described herein provide for monitoring of video streaming events. Techniques disclosed include rendering a first omnidirectional video associated with a first viewpoint. In response to a request to access an omnidirectional video associated with another viewpoint, a time of the request and information identifying the other viewpoint is recorded. Techniques disclosed also include identifying a time of switching into rendering of a second omnidirectional video associated with a second viewpoint, and reporting a viewpoint switching latency, representing a difference between the identified switching time and a recorded request time associated with information identifying the second viewpoint.

This application discloses a method for processing immersive media data performed by a computer device. The method includes: generating an interaction feedback message corresponding to an interaction operation in response to the interaction operation aiming at a first immersive media content, the interaction feedback message carrying a business key field, the business key field being used for describing a business event indicated by the interaction operation; transmitting the interaction feedback message to determine the business event indicated by the interaction operation based on the business key field in the interaction feedback message, and acquires a second immersive media content used for responding to the interaction operation based on the business event indicated by the interaction operation; and receiving the second immersive media content returned by the server for rendering the second immersive media content on a display associated with the computer device.

A method, a computer storage medium, and a client for switching scenes of a panoramic video are provided. The method includes playing a first primary video stream in a first video stream group associated with a first perspective of a user; determining a video stream switching time when a perspective of the user is switched from the first perspective to a second perspective, the video stream switching time being associated with a time length of a video slice in a second backup video stream; and switching from the first primary video stream to the second backup video stream when a play time of the first primary video stream reaches the video stream switching time, so that content of the second backup video stream starting from the video stream switching time is played. The present application can improve the effects of switching between scenes of the panoramic video.

Methods and apparatus for allowing a user to switch viewing positions and/or perspective while viewing an environment, e.g., as part of a 3D playback/viewing experience, are described. In various embodiments images of the environment are captured using cameras placed at multiple camera positions. During viewing a user can select which camera position he/she would like to experience the environment from. While experiencing the environment from the perspective of a first camera position the user may switch from the first to a second camera position by looking at the second position. A visual indication is provided to the user to indicate that the user can select the other camera position as his/her viewing position. If a user input indicates a desired viewing position change, a switch to the alternate viewing position is made and the user is presented with images captured from the perspective of the user selected alternative viewing position.
