摘要： A method includes transmitting a first preauthored video frame of a plurality of preauthored video frames to a client device. The first preauthored video frame is associated with a preauthored media object. The method includes providing a request for a composited video frame to an interactive source device. The request includes a temporal characteristic associated with the first preauthored video frame. The method includes, in response to providing the request, obtaining, from the interactive source device, the composited video frame including customizable video content and preauthored video content. The preauthored video content is associated with a portion of the preauthored media object based on the temporal characteristic. The method includes, in response to detecting that the first preauthored video frame and the composited video frame together satisfy a switching condition, transmitting the composited video frame to the client device after transmitting the first preauthored video frame to the client device.

摘要： A method for receiving and displaying media content may be provided. The method may include requesting a set of DASH video segments that are associated with various viewports and qualities. The method may include displaying the DASH video segments. The method may include determining a latency metric based on a time difference between the display of a DASH video segment and one of: a device beginning to move, the device ceasing to move, the device determining that the device has begun to move, the device determining that the device has stopped moving, or the display of a different DASH video segment. The different DASH video segment may be associated with one or more of a different quality or a different viewport.

摘要： Input digital frames may be down-sampled to create one or more base frames characterized by a lower resolution than the input digital frames. Enhancement information corresponding to a difference between pixel values for the one or more input digital frames and corresponding pixel values of up-sampled versions of the one or more base frames is then created. The one base frames are encoded to form a set of base data and the enhancement information is encoded to form a set of enhancement data. The base data and enhancement data may then be transmitted over a network or stored in a memory.
