Systems and methods for adaptive content streaming based on bandwidth are disclosed. According to one example method, content is requested for delivery. An indication of complexity of a plurality of media content items associated with the content is received. Based on the indication of complexity and an available bandwidth at the user device, at least one of the plurality media content items is selected and retrieved from the media server.

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.

Techniques described herein include evaluation and management of device hardware, software, and network resources during streaming, downloading, or playback of video resources on client devices from remote locations. Certain aspects relate to evaluating the current resources available at a client device, such as memory, processing capacity, device battery status, network availability and/or network data quotas, in view of a video resource request. Based on the evaluation of the client device's resources, and estimations of the effects that video streaming/downloading and playback may have on the client device's resources, the client device may control, customize, and/or alter the retrieval or playback of requested video resources.

A system and method for rendering a video stream for display on a display device, which may comprise receiving the video stream by streaming and generating display data defining a visible display area to be displayed by the display device, wherein generating of display data comprises rendering the video stream in a sub-area of the visible display area. A selection mechanism may be provided by which a version of the video stream may be selected for streaming having a spatial resolution and/or a bitrate which is selected based on a size of the sub-area.

Methods and systems are provided for streaming a media asset with an adaptive bitrate transcoder. A server receives, from a client device, a first request for a first portion of the plurality of portions to be transcoded at a first bitrate. The server then starts to transcode the plurality of portions at the requested first bitrate to generate a plurality of corresponding transcoded portions. The server updates a header of a transcoded portion to include: 1) a transcode latency value; and 2) a count value indicating a number of available pre-transcoded portions of the media asset at the time the first request was received. The server then transmits the transcoded portion to the client. The client device then determines a second bitrate based on the transcode latency value included in the header of the transcoded portion corresponding to the first portion.

An electronic apparatus includes a communication interface, a display, and a processor configured to, based on a content being received from a source apparatus via the communication interface, obtain feature information of the received content, and transmit the obtained feature information to an external server, receive, from the external server, identification information of the content, the identification information being obtained based on the transmitted feature information, based on a predetermined mode of the display being turned on according to a signal that is received from the source apparatus via the communication interface, obtain information regarding a first time point when the predetermined mode is turned on, and based on the predetermined mode of the display being turned off, obtain information regarding a second time point when the predetermined mode is turned off after the first time point.

A system obtains a data set representing immersive video content for display at a display time, including first data representing the content according to a first level of detail, and second data representing the content according to a second higher level of detail. During one or more first times prior to the display time, the system causes at least a portion of the first data to be stored in a buffer. During one or more second times prior to the display time, the system generates a prediction of a viewport for displaying the content to a user at the display time, identifies a portion of the second data corresponding to the prediction of the viewport, and causes the identified portion of the second data to be stored in the video buffer. At the display time, the system causes the content to be displayed to the user using the video buffer.

Described are examples for streaming content at a device. One or more environmental parameters can be determined for the device. One or more parameters for receiving streaming content via one or more streaming servers over one or more network connections can be modified based on the one or more environmental parameters. The streaming content can be received based at least in part on the one or more streaming parameters.

Embodiments provide for methods, computer program products, and systems to improve media playback comprising receiving a variant stream, identifying respective maximum segment durations for a plurality of different types of client devices that will play media content contained in the variant stream, generating, using the variant stream, a respective playlist for each of the plurality of different types of client devices, wherein the respective playlists each contain different maximum segment durations, and delivering the respective playlists to at least one of the plurality of different types of client devices via a distribution network.

A method of processing first video data of a region from incoming video data collected by a camera. The method includes subscribing, by a first subscriber, to an endpoint at which the first video data is published after the first video data is preprocessed according to preprocessing parameters defined within a runtime configuration file. The preprocessing includes formatting the incoming video data to create the first video data of the first region of interest with a second field of view that is less than the first field of view. The method further includes processing, by a computer processor, the first video data to determine at least one output that is indicative of a first inference dependent upon the first video data. The preprocessing parameters that format incoming video data to create the first video data are dependent upon the processing to be performed on the first video data.
