Intelligent control method and device, and electronic device are provided. The method includes transmitting display data and audio data in real time for a projection device through a data channel connected to the projection device; monitoring a state of the data channel and an output state of the audio data on the projection device; and controlling the audio data transmitted in real time to be switched to a playback device for output if the state of the data channel is a connected state and the output state of the audio data on the projection device is an ineffective output state.

A virtual collaboration system provides communication between a plurality of participants via a collaboration session that includes a corresponding plurality of participant devices. The collaboration session facilitates communication between the participant devices via a plurality of communication channels over which the participants communicate. For example, in some embodiments, the channels include one or more of a video channel, audio channel, or document sharing channel. A participant designates in which of the plurality of channels they will participate, and the designations are communicated to other participants. This provides a broader understanding of each participant's circumstances and ability to engage across the different channels with the plurality of participants.

Aspects of the disclosure provide methods and apparatuses for media processing. In some examples, an apparatus includes processing circuitry. The processing circuitry exchanges, with a server device and according to a bidirectional protocol for immersive media, a first plurality of messages that ensures the server device to receive one or more specific characteristics of the apparatus. The processing circuitry receives, from the server device and according to the bidirectional protocol for immersive media, a media stream carrying media content. The media stream includes immersive content and is adapted according to the one or more specific characteristics of the apparatus. The processing circuitry presents the media content from the media stream.

A method for controlling devices to present content includes: determining content to be presented in response to a content request event occurring; determining a content presentation form supported by a presentation device; and providing corresponding presentation content to the presentation device in accordance with a determined presentation form. As such, the current content presentation form can be determined based on the content presentation forms supported by the presentation device, and the content in different presentation forms can be continuously presented, thereby enhancing the user experience.

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.

Systems and methods for quick start-up of playback in accordance with embodiments of the invention are disclosed. Media content may be encoded in a plurality of alternative streams and a quick start-up stream. The quick start-up stream may include media content that is encoded at a lower quality that the alternative streams and may be encrypted with a different, less secure encryption process than that of the alternative streams. During a start-up of playback, the playback device streams the media content from a quick start-up stream until a metric, such as a decryption key for the alternative streams is met. The device then streams the media content from the alternative streams in response to the metric being met.

An electronic device includes at least one display, a communication circuit, at least one processor, and a memory. The processor is configured to obtain information on a first display aspect ratio associated with a current state of the at least one display if an input indicating initiation of a video call is received.

Systems, methods, and machine-readable media for adapting content items to device operations of an endpoint media device are disclosed. A first content composite may be created by one or more processing devices for delivery in a packet stream from a content provider system via one or more networks, where the first content composite may include an adaptable content item corresponding to a set of one or more audio and/or video packets corresponding to audio and/or video content. The first content composite may be transmitted, where, consequent to delivery of the first content composite to a first endpoint media device or a second endpoint media device, the first endpoint media device or the second endpoint media device may perform one operation relating to a second content item of the first content composite, where the adaptable content item may be modified based on the second content item.
