A method and device for transmitting or receiving a broadcast signal are discussed. The method for transmitting the broadcast signal can include processing one or more Internet Protocol (IP) packets into link layer packets, processing the link layer packets to output the broadcast signal, and transmitting the broadcast signal. The one or more IP packets can carry components of a service and service signaling information for signaling the components of the service. The broadcast signal can further include a service list table. The service list table can include one or more of service identification information for identifying the service, capabilities information related to the service, channel number information of the service, category information for indicating a type of the service, protocol information for representing a type of a protocol used to deliver the service signaling information.

Techniques have been developed to facilitate the livestreaming of group audiovisual performances. Audiovisual performances including vocal music are captured and coordinated with performances of other users in ways that can create compelling user and listener experiences. For example, in some cases or embodiments, duets with a host performer may be supported in a sing-with-the-artist style audiovisual livestream in which aspiring vocalists request or queue particular songs for a live radio show entertainment format. The developed techniques provide a communications latency-tolerant mechanism for synchronizing vocal performances captured at geographically-separated devices (e.g., at globally-distributed, but network-connected mobile phones or tablets or at audiovisual capture devices geographically separated from a live studio).

Systems and methods are described herein for controlling playback and/or recording of media assets at a media device based on the state of a secondary device. Specifically, while displaying a media asset, a media device receives a signal from the secondary device indicating a change of state of the secondary device. The media device displays a notification of the signal, and the user can interact with the notification. If the user interacts with the notification for more than a threshold amount of time, the media device may begin recording the media asset. Once the user has finished interacting with the notification, the media device may stop recording and the user can see content that they may have missed by reviewing the recorded portion of the media asset.

This application discloses a video source switching method, a playing method, an apparatus, a device, and a storage medium. The video source switching method includes obtaining switching information; determining a first key frame of a first video source according to the switching information, the first key frame being a next key frame of a current playing time of the first video source; querying a first time value of the first key frame; identifying a second video source according to the switching information; and switching video sources if a distance between a current time value of the second video source and the first time value is less than or equal to a threshold.

The present technology can provide a mechanism for adjusting a visual effect that is associated with an audio artifact at a given frequency bandwidth that is attenuated by speaker characteristics. The intensity of the visual effects that is adjusted can also be attributed to a change in volume settings of a processing device as well as an intensity of a multimedia skin in which the visual effect is encoded. The multimedia skin includes filters, transitions/animations, and/or image universal processing, that can be applied to any set of photos, videos, and/or songs, in order to create, in real-time, many variations of the same digital multimedia file, wherein each multimedia skin leads to a specific video rendering.

A non-transitory computer-readable recording medium storing instructions that, when executed by a processor, cause the processor to set a communication session in which a plurality of users participate through a server, generate data for a virtual space, share motion data related to motions of the plurality of users through the communication session, generate a video in which avatars following the motions of the plurality of users are represented in the virtual space, based on the motion data, and share the generated video with the plurality of users through the communication session.

Systems and methods are presented for providing dynamic summaries of missed content of content streaming on multiple device. A plurality of groups for a concurrent presentation of a content is identified, and a selection is received by a user via a second device to join a first group of the plurality of groups for the concurrent presentation of the content. Based on a user via the second device joining a group, a determination is made as to whether a user via the second device missed any content from the concurrent presentation of the content for the first group. Based on the detection of missed content, the system generates for the second device one or more summaries of the missed content segments and the missed reactions to the segments based on preferences associated with the user profile. In response to generating the summaries, the summaries are presented via the second device to the user.

There is provided a system and method for the synchronizing on-air commercial programming with interactive applications, providing interactive content synchronized with on-air television programming. There is provided a system comprising a client device with a display device and an input device and running a synchronization application. The client device receives digital data transmitted from a server, and transmits user feedback information generated from user interactions with the digital data back to the server. The digital data are interactive advertisements, such as online social games, that increase users' awareness of the advertised products or messages. The digital data are delivered to the user's client device in synchronization with the broadcasting of on-air television commercials.

A transmission method includes generating one or more frames for content transfer using IP (Internet Protocol) packets, and transmitting the one or more generated frames by broadcast. Each of the one or more frames contains a plurality of second transfer units, each of the plurality of second transfer units contains one or more first transfer units, and each of the one or more first transfer units contains at least one of the IP packets. An object IP packet of the IP packets which is stored in a first transfer unit positioned at a head in the one or more frames contains reference clock information that indicates time for reproduction of the content in data structure different from data structure of an MMT (MPEG Media Transport) packet, and header compression processing on the object IP packet is omitted.

Methods and system for providing content are disclosed. One method can comprise receiving a request for data at a first time, wherein the data comprises a first time duration, determining a buffer size based upon the first time duration, and determining a playback window based upon the determined buffer size and the first time. The method can also comprise synchronizing presentation of content on a plurality of devices.
