Various implementations disclosed herein include devices, systems, and methods for reducing a decode delay at a client device. In some implementations, a device includes one or more processors and a non-transitory memory. In some implementations, a method includes determining that a client device is being switched from a real-time content presentation mode in which the client device presents real-time content to a buffered content presentation mode in which the client device presents buffered content. In some implementations, the method includes transmitting, to the client device, video frames corresponding to the buffered content at a first transmission rate. In some implementations, the method includes changing the first transmission rate to a second transmission rate based on an indication that a number of bits stored in a buffer of the client device satisfies a decode threshold.

Reducing decode delay at a client device

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.

Switching between transmitting a preauthored video frame and a composited video frame

A method includes determining a first transmission rate for transmitting an entirety of a segment of a video stream to a client device. The segment includes a set of frames. In some implementations, the method includes, after transmitting a first subset of the set of frames at the first transmission rate, detecting that a network connectivity of the client device has reduced below a connectivity threshold associated with the first transmission rate. In some implementations, the method includes transmitting an entirety of the segment at a second transmission rate that is less than the first transmission rate. In some implementations, the method includes triggering the client device to present a second subset of the set of frames that corresponds to a temporal position in the video stream after the first subset of the set of frames while foregoing re-presentation of the first subset of the set of frames.

Intrasegment adjustment of video transmission rate

A method is performed at a network device including a plurality of network interfaces. The method includes obtaining a first source adaptive bitrate (ABR) asset and a second source ABR asset. The method includes encoding the first source ABR asset in order to generate a first plurality of video representations, and encoding the second source ABR asset in order to generate a second plurality of video representations. The method includes providing, to a first client device, a first one of the first plurality of video representations. The method includes, in response to detecting satisfaction of a source change condition with respect to the first client device, providing, to the first client device, a first one of the second plurality of video representations, and ceasing to provide the first one of the first plurality of video representations to the first client device.

Distributed adaptive bitrate (ABR) asset delivery

A method includes transmitting, to a client device, a portion of a first ABR segment, characterized by a first representation, according to a first predefined protocol, and transmitting a first buffer management instruction that is associated with the portion of the first ABR segment. The method includes obtaining a performance status characteristic from the client device. The performance status characteristic characterizes the client device receiving the portion of the first ABR segment. The method includes, in response to determining that the performance status characteristic satisfies a representation change condition, transmitting, to the client device, a portion of a second ABR segment, characterized by a second representation, according to a second predefined protocol that is different from the first predefined protocol, and transmitting a second buffer management instruction that is associated with the portion of the second ABR segment.

Management of a client device buffer

A method is performed at a network device including a plurality of network interfaces. The method includes receiving, from a client device, a playback request associated with a plurality of preauthored video frames. The method includes, in response to receiving the playback request, delivering, to the client device, customizable content that is based on the playback request. The method includes detecting that a first portion of the plurality of preauthored video frames and a portion of the customizable content together satisfy a switching condition. The method includes, in response to detecting that the first portion of the plurality of preauthored video frames and the portion of the customizable content together satisfy the switching condition, switching delivery of the customizable content to the client device with delivery of the first portion of a plurality of preauthored video frames to the client device.
