摘要： Systems, apparatus, articles of manufacture, and methods are disclosed to synchronize media playback at devices in a multicast environment. Disclosed is a system to synchronize media playback, the system comprising programmable circuitry, and a memory that stores executable instructions that, when executed or instantiated by the programmable circuitry, facilitate performance of operations, comprising transmitting, using a hypertext transfer protocol (HTTP), a first request in a first HTTP message to a first client device and to a second client device, receiving, from the first client device in response to the first request. a first time stamp associated with a first presentation, the first time stamp representing a first playback time within the first presentation, receiving, from the second client device in response to the first request, a second time stamp associated with a second presentation, the second time stamp representing a second playback time within the second presentation, calculating a time difference between the first time stamp and the second time stamp, determining whether the time difference satisfies a threshold, transmitting a second HTTP message to the first client device and the second client device in response to a determination that the time difference fails to satisfy the threshold, the second HTTP message to cause the first client device to pause the first presentation and the second client device to pause the second presentation, transmitting seek instructions in a third HTTP message to the second client device, the seek instructions to cause the second client device to synchronize the second presentation to the first presentation by setting the first and second playback times equal, and transmitting a fourth HTTP message to cause the first client device to resume the first presentation and the second client device to resume the second presentation.

摘要： Embodiments create a structured representation of user feedback received from a media player, where the user feedback relates to a media item played by the media player or a particular segment of a media item played by the media player. A device may receive a first selection signal from a first media player of a first user device. A device may, based on the first selection signal, determine first timestamp data, where the first timestamp data is associated with a first segment of a media item played by the first media player. A device may receive first user feedback from the first media player. A device may, based on the first timestamp data, create a first structured representation of the first user feedback, where the first structured representation includes a first feedback category. A device may create and store a first data record that includes the first feedback category.

摘要： A video packaging and origination service can include one or more encoder components that receive content for encoding and transmitting to requesting entities. During the operation of the encoder components, a management service associated with the video packaging and origination service can receive information related to updates or modifications to the encoder components. Responsive to the information, the management service can instantiate and configure an updated encoder. Once the updated encoder component is instantiated and configured, both the updated and target encoder components receive content for streaming, encode content and generating encoding content. Additionally, the updated encoder component can initiate a notification to the target encoder component that a handover will be occurring and begin a negotiation process identifying a handover event. Based on the negotiated handover event, the target encoder component can illustratively cease operation upon evaluation and detection of the handover event.

摘要： A timecoding technique for determining and assigning timecodes for variable frame rate video. Content identified for timecode assignment is decoded, and for sequential frames of the content, portions of timestamps are compared to determine if the frames are from a same time period (e.g., from the same second in time). For a subsequent frame from the same time period, an index is atomically incremented, a timecode generated from a combination of the time period and the index, and the timecode assigned to the frame. For a subsequent frame from a different time period, the index is initialized, a timecode generated from a combination of the different time period and the initialized index, and the timecode assigned to the frame. Accumulated durations of frames may be used in place of timestamps, in some instances.

摘要： A data deduplication method includes: acquiring a live streaming data stream to be processed, wherein the data stream includes at least one audio/video packet; and executing following operations on one audio/video packet, each audio/video packet carrying an identifier, and the identifier being determined according to the order of the audio/video packet in the live streaming data stream; determining, according to the identifier of the audio/video packet, whether the audio/video packet is a repeatedly acquired audio/video packet, and if so, discarding the audio/video packet. Accordingly, it is ensured that no unduplicated data is sent to a user, and the problem that in a live streaming process, due to the fact that an intermediate link is reconnected, a user acquired part of duplicated data, and the audio/video rollback phenomenon caused by the duplicated data being played is solved.

摘要： The present disclosure relates to a signal processing system and a signal processing method that enable realization of display optimization in a real-time service. A transmission device transmits an image signal from an imaging device, a processing device provided on a cloud performs signal processing on the transmitted image signal, and a reception device receives the image signal subjected to the signal processing. An integration device is connected to a network together with the transmission device, the processing device, and the reception device which are time-synchronized, sets a signal delay amount from the transmission device to the reception device in accordance with a signal processing content of the processing device, and transmits the signal delay amount to the reception device. The present disclosure can be applied to a network system for medical use and a network system for use in a broadcasting station.

摘要： Embodiments of the present invention provide a system for embedding extractable metadata elements within a channel-agnostic layer of audio-visual content. The system is configured for receiving a content file, determining products displayed in the content file, and delivering resource metadata related to the products displayed in the content file in an interactive and secure manner. The invention may further include various ways in which to automatically display resource metadata in an intuitive manner in conjunction with streaming the content file to a user device via one or more platforms or channels.

摘要： Methods and systems are disclosed maintaining playback of content at a target or desired playback time. A playback device may be configured to compare a current playback time of a content asset to a target playback time of the content asset and to determine, for each comparison, whether a difference between the current playback time and the target playback time has reached a threshold. Based on determining that the difference between the current playback time and the target playback time has reached a threshold, the playback device may seek to the target playback time of the content asset. The playback device may be configured to repeatedly perform the comparing, determining and seeking operations in order to maintain the current playback time of the content within the threshold of the target playback time.
