A video display apparatus for displaying a catalogue of one or more candidate video items for replay, each video item being represented in the catalogue by a catalogue entry having at least one displayed representative image comprises a user control device operable to resize a displayed catalogue entry by a select-and-drag operation; and means responsive to a resizing of a catalogue entry to select a number of distinct representative images, for display in respect of that video item, so that the number displayed increases with increasing size of the catalogue entry while the display size of each representative image stays substantially constant with respect to changes in the catalogue entry size.

Generating structured data from screen recordings is disclosed, including: obtaining, from a client device, a screen recording of a user's activities on the client device with respect to a task; performing, at a server, video validation on the screen recording, including by determining whether the screen recording matches a set of validation parameters associated with the task; and generating a set of structured data based at least in part on the video validation.

According to various embodiments, a content marking command is received from a mobile device at a particular time. For example, a user selection of the content marking command may be received via a user interface displayed on the mobile device. The content marking command may indicate a user interest in a particular moment of an event viewed by the user. Moreover, the event viewed by the user and video content data corresponding to the event may be identified. Further, content marking data may be generated, whether content marking data indicates a particular portion of the identified video content data corresponding to the particular moment of the event.

Video content is evaluated to classify one or more scenes or objects of the video content. The classifications may be evaluated against one or more rules for determining whether to include keywords associated with the classifications for targeting supplemental content. Classifications that satisfy the one or more rules may be used for selection of supplemental associated with one or more keywords Selected supplemental content may be included in video content in a break period following primary content.

A method for transmitting a multimedia resource, including: determining target address information based on a media presentation description of a multimedia resource, where the media presentation description includes address information of the multimedia resource having different code rates, and the target address information is address information of the multimedia resource having a target code rate; and sending a frame acquiring request carrying the target address information to a server, where the frame acquiring request is configured to instruct the server to return media frames of the multimedia resource at the target code rate.

One high-level aspect of a content-modification system and related methods may involve facilitating content modification by a content-presentation device of received broadcast content in a controlled manner, while under circumstances in which some events that can impact timing may be unpredictable. In particular, certain operations by a content-presentation device may involve matching received content with specific expected content as determined by one or another component of the content-modification system, in order to confirm proper conditions are met for the content-presentation device to proceed with, or continue, content-modification operations. It can happen the matching procedure becomes subject or susceptible to timing irregularities, or jitter. In some instances, jitter may impact the ability to derive the benefits of content modification. Accordingly, example embodiments herein are directed to systems and method for compensation and/or mitigating the effects of jitter.

A data storage device and method for application-defined data retrieval in surveillance systems are provided. In one embodiment, a data storage device is provided comprising a memory and a controller. The controller is configured to store, in the memory, a stream that combines data from a plurality of receivers; receive a request from a host for data generated by a selected receiver; extract, from the stored stream, the data generated by the selected receiver; and send the extracted data to the host. Other embodiments are provided.

Disclosed are examples for providing functions to receive a media file to be stored in a media repository. In the examples, a location in the media repository may be assigned to the media file. A media file address in a blockchain platform may be assigned to the media file. Metadata including the assigned location in the media repository and the assigned media file address in the blockchain platform may be added to the media file. A media file hash value may be generated by applying a hash function to the media file including the metadata. The media file hash value may be included in a message and uploaded to the assigned media file address in the blockchain platform as a transaction in the blockchain. An indication that the media file is uploaded to the media repository may be delivered to a subscriber device from which the media file was received.

Improved technical functionality is provided to dynamically select and seamlessly play advertisements immediately before playing of a recorded program upon selection of the recorded program for playing, or upon other detected events and conditions associated with the set-top-box (STB) or user. In some embodiments, this is performed by using metadata which may be delivered to and stored on a digital video recorder (DVR) prior to recording the program, providing a technical solution to enable opportunities for additional advertisement impressions. Playing of the advertisement may also or instead occur upon the recorded program finishing playing. Thus, the technical solution provides the additional opportunity for the content creator and/or the satellite television or cable service provider to sell advertising spots in addition to those already sold for breaks within the recorded program.
