An example display device includes a display; a memory configured to store a plurality of applications that provide a content playback service; and a processor configured to: store information on the plurality of applications, information on a plurality of contents, and information on a point of time when playback is stopped in the memory when the playback of the plurality of contents played through the plurality of applications is stopped, and display a user interface (UI) screen for playing the plurality of contents from the point of time when the playback is stopped on the display using the information stored in the memory, when an application that provides a continuous content playback service is executed.

A storage system and method for time-based data retrieval are provided. In one embodiment, a controller of the storage system is configured to receive time information from a host; receive a write command from the host, wherein the write command comprises a logical block address; and create a time-to-logical-block-address map from the time information and the logical block address received from the host. Other embodiments are provided.

Systems, methods, and computer program products to perform an operation comprising receiving a first unit of video data on a first input/output (I/O) channel, of a plurality of I/O channels of a digital video recorder, computing a first value by applying an error-detecting function to the first unit of video data, attempting to write the first unit of video data to a storage location of a storage device communicably coupled to the digital video recorder, computing, after attempting to write the first unit of video data, a second value by applying the error-detecting function to a data stored at the storage location of the storage device, and upon determining that the first and second values are not equal, storing an indication that the first unit of video data was not successfully written to the storage location of the storage device.

A storage system and method for high-correlation data analysis with unified time mapping are provided. In one embodiment, a controller of a storage system is configured to receive a data stream from a host, wherein the data stream comprises a clock reference signal configured to synchronize playback of audio and video in the data stream, wherein the clock reference signal is mapped to a clock of the host; map a clock of the storage system to the clock reference signal of the data stream; tag a storage system parameter with a time stamp generated by the clock of the storage system; and send the tagged storage system parameter to the host. Other embodiments are provided.

Embodiments of the present disclosure relate to a method, a device, and a computer program product for storing and providing a video. A method for storing a video is provided, including: acquiring frame storage information in a to-be-stored video, the frame storage information including information related to storage of a plurality of frames in the video; converting the video into a plurality of data blocks based on the frame storage information; and converting the frame storage information into a streaming media index file to characterize the video in association with the plurality of data blocks. Embodiments of the present disclosure further provide a method for providing a video.

An information embedded method is used with a broadcast source and a broadcast signal receiver using a unidirectional transmission medium. The information embedded method includes steps of: storing information-push files in the broadcast signal receiver during a first time period; the broadcast source delivering broadcast signals to the broadcast signal receiver through the unidirectional transmission medium during a second time period posterior to the first time period; and the broadcast signal receiver selecting one of the information-push files according to a predetermined rule and combining the broadcast signals and information content of the selected information-push file to form an information embedded program. An information embedded system includes the broadcast source and the broadcast signal receiver.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. Broadcaster non-real time (NRT) data packets are downloaded into RAM memory first and then saved to disk once the complete NRT package is in RAM. Old saved NRT data is retained until channel change with new NRT data, at which point old NRT data may be deleted before starting to save the new oncoming NRT data. Old NRT data may be deleted only when the new oncoming NRT data is not the same as the old.

Method of recording a multimedia content broadcast streamwise, comprising the following steps: initialize a current throughput of recording of the stream in a mass memory; acquire a current portion of the multimedia content at the current recording throughput, and store it temporarily in the buffer memory; evaluate a rate of fill of the buffer memory; if the fill rate is greater than a predetermined high threshold of fill, decrease the current recording throughput; if the fill rate is less than or equal to a predetermined low threshold, increase the current recording throughput.
