Methods, systems, and media for adjusting quality level during synchronized media content presentation are provided. In some embodiments, the method comprises: transmitting, from a server to a first user device, first media content data corresponding to a first stream of a media content item and from the server to a second user device, second media content data corresponding to a second stream of the media content item, wherein the first media content data is to be stored in a buffer of the first user device, and wherein the second media content data is to be stored in a buffer of the second user device; transmitting, from the server to the first user device and to the second user device, instructions that cause the first user device and the second user device to begin presenting the media content item simultaneously; determining, by the server, that the first media content data is being stored in the buffer of the first user device at a slower rate than the second media content data is being stored in the buffer of the second user device; in response to determining that the first media content data is being stored in the buffer of the first user device at a slower rate than the second media content data is being stored in the buffer of the second user device, selecting a third stream of the media content item corresponding to the first stream of the media content item, wherein the third stream of the media content item has a lower quality level than the first stream of the media content item; and transmitting third media content data corresponding to the third stream of the media content item to the first user device.

User interface techniques provide user vocalists with mechanisms for solo audiovisual capture and for seeding subsequent performances by other users (e.g., joiners). Audiovisual capture may be against a full-length work or seed spanning much or all of a pre-existing audio (or audiovisual) work and in some cases may mix, to seed further contributions of one or more joiners, a user's captured media content for at least some portions of the audio (or audiovisual) work. A short seed or short segment may span less than all (and in some cases, much less than all) of the audio (or audiovisual) work. For example, a verse, chorus, refrain, hook or other limited “chunk” of an audio (or audiovisual) work may constitute a short seed or short segment. Computational techniques are described that allow a system to automatically identify suitable short seeds or short segments. After audiovisual capture against the short seed or short segment, a resulting, solo or group, full-length or short-form performance may be posted, livestreamed, or otherwise disseminated in a social network.

A system is disclosed for processing and streaming real-time graphics by a video-server for synchronized output via secondary-network connected display adapters to multiple displays arranged as a video-wall. This system enables the video-server to leverage performance advantages afforded by advanced GPUs, combined with low-cost Smart displays or System-on-Chip devices to deliver advanced realtime video-wall capabilities over the network while offering flexibility in the selection of network display adapters and still achieving synchronized output of multiple sub-image streams to selected end-point displays. This has applications generally in the field of real-time multiple-display graphics distribution as well as specific applications in the field of network video-walls. A method and computer readable medium are also disclosed that operate in accordance with the system.

In a video system for imaging a target object by using first and second imaging devices, an information processing method is executed by the first imaging device. The information processing method includes: a step for acquiring a first elapsed time indicating the time elapsed after start of recording by the first imaging device; a step for requesting the second imaging device to transmit a second elapsed time indicating the time elapsed after start of recording by the second imaging device, and receiving the second elapsed time; a step for acquiring a required time to receive the second elapsed time after the request is made; and a step for, based on the first elapsed time, the second elapsed time, and the required time, calculating an offset time for synchronizing a first moving image recorded by the first imaging device and a second moving image recorded by the second imaging device.

The disclosed computer-implemented method includes determining, for multiple different media items, a current time scale at which the media items are encoded for distribution, where at least two of the media items are encoded at different frame rates. The method then includes identifying, for the media items, a unified time scale that provides a constant frame interval for each of the media items. The method also includes changing at least one of the media items from the current time scale to the identified unified time scale to provide a constant frame interval for the changed media item(s). Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for real-time incorporation of user-produced content into a broadcast media stream are provided. A media title may be streamed to a producer computing device over a communication network. The producer computing device is associated with a channel for distributing the user-produced content in conjunction with the media title. Produced content may be captured from the producer computing device as the streamed media title is played on the producer computing device. Such captured produced content may be designated for the channel. The media title and the produced content may then be broadcast in real-time over the communication network to one or more subscriber devices subscribed to the channel. The media title and the produced content may be synchronized within the broadcast to reflect when the produced content was captured in relation to the media title as the media title was played on the producer computing device.

Described herein is a methods and systems for providing a digital interactive experience. Interactive experiences include, but not limited to, synchronized video playback, video and text chat between two or more participants, and interactive live event participation combining synchronized video, text and video chatting. The system comprises persistent and non-persistent components to which a plurality of participants in the interactive experience may connect.

Index values are periodically incremented at a central or primary video production control system and a video production control system node. Messages that include or otherwise indicate current index values generated by the primary video production control system are transmitted to the video production control system node, and the node reflects the messages back to the primary video production control system. The primary video production control system determines a round-trip message time, associated with the video production control system node, based on the transmitted messages and reflections of the messages received from the node. A further message that includes or otherwise indicates an instruction for execution of a task at a target execution time, is transmitted by the primary video production control system to the node at a time, in advance of the target execution time, that is based on the round-trip message time.
