A method and a system for virtual reality, augmented reality, mixed reality, or 360-degree Video environment is disclosed. The system receives Video Streams associated to audio and video scenes to be reproduced and Audio Streams associated to audio and video scenes to be reproduced. There are provided a Video decoder which decodes signal from the Video Stream for the representation of the audio and video scene; an Audio decoder which decodes signal from the Audio Stream for the representation of the audio and video scene to the user; and a region of interest processor deciding, based e.g. on the user's viewport, head orientation, movement data, or metadata, whether an Audio information message is to be reproduced. At the decision, the reproduction of the Audio information message is caused.

A system that handles delivery of service(s) through a client device, includes an interactive service provider, a video service provider, and a client device. The interactive service provider inserts at least one of digital watermarks and digital fingerprints in non-programming media content. The video service provider transmits a media stream of the media content that includes programming media content and the non-programming media content. The client device detects at least one of the inserted digital watermarks and the digital fingerprints in the playback duration of the media content and renders overlay graphics on the media content. The client device activates at least one of input devices paired with the client device and the rendered overlay graphics. The client device further receives trigger responses over activated overlay graphics and displays an interactive view to enable delivery of service(s) in response to the trigger responses.

Various embodiments describe methods, systems, and devices for deploying live media content as a time-shifted playback. Exemplary implementations may receive, from a client computing device, a content request for a time-shifted playback of live media content. The time-shifted playback may use a unique copy of a live media content configured for playback associated with the content request. The content request may indicate a past point in time in the live media content from which the time-shifted playback originates. The client computing device may be provided access to an assigned private path for accessing segments of the time-shifted playback starting from a requested segment that corresponds to the indicated past point in time. Access by the client computing device to further segments of the time-shifted playback may be prevented in response to determining that the subsequent content request for playback of the second live media content is received.

In some embodiments, a system is provided, and computer-executable instructions cause the system to: obtain, at an edge server of a content delivery network, a request for a content item from a client device; determine that the there are multiple versions of the first content item that require varying amount of resources to serve including a first version, and a second version requiring more resources to serve than the first version; select the second version; send the second version; determine that the client device is not properly rendering the second version of the content item; and in response to determining that that the client device is not properly rendering the second version, send the first version.

In one aspect, a method includes identifying an upcoming content-modification opportunity on a channel, where the upcoming content-modification opportunity relates to a modifiable content-segment transmitted by a content-distribution system on the channel, and where the modifiable content-segment includes an overlay content portion and a non-overlay content portion. The method also includes responsive to identifying the upcoming content-modification opportunity on the channel, identifying a content-presentation device tuned to the channel. The method also includes determining location data associated with the overlay content portion. The method also includes transmitting, to the identified content-presentation device, the determined location data to facilitate the content-presentation device performing a content-modification operation in connection with the identified upcoming content-modification opportunity on the channel, where performing the content-modification operation involves replacing only the non-overlay content portion with supplemental content.

Methods, systems, and media for synchronizing video streams are provided. In some embodiments, the method comprises: identifying a target video stream and a reference video stream, wherein the target video stream and the reference video stream are two different broadcasts of a program; generating, for the target video stream, a sequence of fingerprints; determining a time shift at which the sequence of fingerprints appears within the reference video stream; determining whether the target video stream is synchronized with the reference video stream by determining whether the time shift exceeds a predetermined threshold; and, in response to determining that the target video stream is not synchronized with the reference video stream, causing an electronic programming guide that includes an indication of the target video stream to be modified based on the time shift.

A content controller system to render frames on demand comprises a rendering server system that includes a plurality of graphics processing units (GPUs). The GPUs in the rendering server system render a set of media content item segments using a media content identification and a main user identification. Rendering the set of media content item segments includes retrieving metadata from a metadata database associated with the media content identification, rendering the set of media content item segments using the metadata, generating a main user avatar based on the main user identification, and incorporating the main user avatar into the set of media content item segments. The rendering server system then uploads the set of media content item segments to a segment database; and updates segment states in a segment state database to indicate that the set of media content item segments are available. Other embodiments are disclosed herein.
