Embodiments of the present invention provide a method and apparatus for publishing a video synchronously, an electronic device, and a readable storage medium. The method comprises: receiving a video publishing request by means of a first video publishing platform, wherein the video publishing request comprises a video identification, a user identification, and a video synchronization identification of a video to be published, and the video synchronization identification is used for identifying a second server corresponding to at least one second video publishing platform required to synchronously publish said video; and in response to the video publishing request, sending the video publishing request to a first server corresponding to the first video publishing platform, so that the first server sends, on the basis of the video synchronization identification, the video identification and the user identification to the second server.

The systems and methods are described herein for playback of content based on progress point information. The systems and methods detect nearby media devices to transmit or request progress point information. Based on the communicated progress point information, the system may generate an option to play back content at a point within the content up to which content was last consumed. When content providers offer different versions of one content item and the user does not select to play back content from the content provider associated with the progress point information, the system determines a proper playback point in other content providers.

An audio content playback method for a portable terminal. The audio content playback method includes checking a channel that is supportable by audio content that is currently engaged in group's simultaneous playback, in group's simultaneous playback of the audio content. The method includes allocating a channel to each of devices included in a group based on position information of each device included in the group or based on an input state in a user interface environment that is preset for channel allocation for each device included in the group, and transmitting the allocated channel information to each device included in the group to allow the device to select its allocated channel and play the audio content.

In one aspect, a method includes: (i) determining a baseline input-to-output delay, which represents a time period between when content is input into a first input buffer and output by an output buffer; (ii) establishing a synchronous lock between (a) first fingerprint data representing content in the first input buffer and (b) second fingerprint data representing content in the output buffer; (iii) determining an instruction time-point at which a content-presentation device is instructed to switch from using content in the first input buffer to populate the output buffer, to using content in the second input buffer to populate the output buffer; (iv) determining a loss of synchronous lock time-point; (v) using the determined baseline input-to-output delay, the determined instruction time-point, and the determined loss of synchronous lock time-point to determine an input-buffer switching delay; and (vi) using the determined input-buffer switching delay to facilitate performing a content-modification operation.

Systems and methods for identifying, assembling, and transmitting content are described in the illustrative context of electronic program guides and program channels. A first system causes an interactive interstitial to be presented on a remote first device of a user in conjunction with a scheduled program. The first system determines if a second device of the user is available to receive an interstitial interaction request. At least partly in response to determining that the second device is available to receive an interstitial interaction request, the interstitial interaction request is presented via a client hosted on the second device. At least partly in response to determining that the user has provided an interaction via the second device, the interaction is stored in memory. Optionally, an interstitial is composed based at least in part on the user interaction. The composed interstitial is optionally displayed via the first device of the user in conjunction with a scheduled program.

According to one aspect of the present disclosure, a transmission method for enabling transmission of content using a broadcast and a communication channel includes: transmitting playback control information and service information using at least the broadcast wave, the service information being information for playing back content transmission using the broadcast and content transmission using the communication channel when the content is transmitted using the broadcast and the communication channel. The service information includes attribute information indicating that the first content data and the second content data constitute the content and location information that indicates a location for acquiring meta-information on playback control of the second content. The playback control information includes indexes of a relationship between the first content data and the second content data.

In some implementations, a system is capable of dynamically associating content streams to improve a user's viewing experience while accessing primary content. To accomplish this, the CMS uses content association data assigning secondary content items to the primary content. Secondary content items can be assigned to designated frames of the primary content so that the secondary content items are presented to user at specified time points during the playback of the primary content. Secondary content items can represent content that is related to the subject matter of the primary content, or content that a user may be interested in accessing while viewing the primary content.

Methods, systems, computer readable media, and apparatuses for providing synchronous supplemental experiences are presented. According to one or more aspects, a video signal may be transmitted to a display device, and a sync signal may be transmitted to at least one other device. The sync signal may include an identifier of a program currently being displayed and a time value indicating a current point in time of the program. In at least one arrangement, the sync signal may cause the at least one other device to access content synchronization data; determine, based on the content synchronization data, that at least one supplemental experience corresponds to the identifier of the program and the time value; and present the at least one supplemental experience to a user.

A system for the production of an audiovisual content includes one or more audiovisual sources adapted to generate one or more audiovisual signals at a first quality level; at least one audiovisual processing apparatus operatively connected to the audiovisual sources; at least one remote control unit operatively connected to the audiovisual processing apparatus via a data communication network; the audiovisual processing apparatus being configured for receiving the one or more audiovisual signals at a first quality level from the one or more audiovisual sources; generating at least one copy of the one or more audiovisual signals, the copy being at a second quality level; sending the copy of the one or more audiovisual signals to the remote control unit via the data communication network; receiving, via the data communication network, at least one control signal containing one or more instructions from the remote control unit; generating an audiovisual content on the basis of the one or more audiovisual signals as a function of the one or more instructions.

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.
