This invention discloses a digital TV broadcast system coordinated with a broadband communication network, an information transmission network in which the broadcast system is applied, a digital TV heterogeneous network architecture, and a client terminal used in each of the above network systems. The various broadcast system architectures of the invention adopt the design concept of heterogeneous network which integrates a broadcast network with other networks, for example, a communication network, the Internet and the like, to form a heterogeneous network architecture coordinating various networks. Meanwhile, the usage in bad conditions are taken into account, and a broadcast TV system which enables uplink transmission by using a broadcast link is designed. The terminal of the invention is a terminal applicable in these heterogeneous network architectures, is capable of receiving signals transmitted from various networks, and can enable flexible receiving and access modes with a series of control means. The network system and client terminal of the invention can achieve an optimized allocation of network resources, save spectrum resources, and enable optimized transmission and management of information resources.

Digital content, such as video, audio, multimedia, and similar files may be associated with metadata that is in some manner descriptive of the content by means of a unique identifier generated based on the content or a portion of the content. The two may be packaged in a wrapper. If the content is separated from the metadata, such as by circulation in a non-compliant environment, the content may be recognized by a regeneration of the identifier. Based upon the re-created identifier, the metadata may be re-associated with the content. Other scenarios may include generation of compilations for files that are not included in a wrapper with content and metadata, content that becomes dissociated with metadata by transcoding, and so forth.

Various arrangements for metadata tagging of video content are presented. A request to add a metadata tag to be linked with a video content instance may be received. A metadata integration database to link the spoken metadata tag with the video content instance may be updated.

Particular embodiments generate a database table that keeps track of authorization package combinations for videos being offered by a video delivery service. The table may allow the video delivery service to keep track of how much content is available for a specific authorization package combination that a user might have access to In one embodiment, the video delivery service does not pre-generate every single possible authorization package combination on a per-show basis. Rather, only a subset of the authorization package combinations is generated for each show. Then, the video delivery service uses a query to the database table that can calculate which content a user is authorized to access from the subset of authorization package combinations that were generated.

Images may be periodically captured from each of a plurality of content streams comprising programs. Each of the content streams may be associated with capture parameters. The capture parameters may include information on how frequently images from the stream may be captured. The captured images may be made available to various clients for various uses, such as for display of a schedule of available programs.

Systems and methods are provided herein for generating and providing a playlist of content relevant to a user that is to be played back instead of advertisement content. In some embodiments, a media guidance application may access a profile of a user, and may generate a playlist comprising a plurality of program content based on data of the profile. The media guidance application may determine that advertisement content is imminently to be played back to the user, and, in response to determining that the advertisement content is imminently to be played back to the user, the media guidance application may select program content of the playlist to play back instead of the advertisement content, and generate for display the program content.

Disclosed herein are methods and systems to help disambiguate channel identification in a scenario where fingerprint data of media content being rendered by a media presentation device matches multiple reference fingerprints corresponding respectively with multiple different channels. Upon detecting such a multi-match, a server or other entity will perform disambiguation based at least in part on a comparison of time of broadcast of the media content being rendered by the media presentation device with time of broadcast of the media content represented by the reference fingerprints. The server or other entity will thereby determine the channel on which the media content being rendered by the media presentation device is arriving, so as to facilitate taking channel-specific action.

In certain embodiments, training of a neural network or other prediction model may be facilitated via live stream concept association. In some embodiments, a live video stream may be loaded on a user interface for presentation to a user. A user selection related to a frame of the live video stream may be received via the user interface during the presentation of the live video stream on the user interface, where the user selection indicates a presence of a concept in the frame of the live video stream. In response to the user selection related to the frame, an association of at least a portion of the frame of the live video stream and the concept may be generated, and the neural network or other prediction model may be trained based on the association of at least the portion of the frame with the concept.

A computing system receives from a media presentation device a query fingerprint stream representing media content being presented by the media presentation device, where the query fingerprint stream has been determined to represent a first channel. The computing system then detects that a threshold mismatch exists between the received query fingerprint stream and a reference fingerprint stream representing the first channel, thus indicating a likelihood that the media presentation device has transitioned from presenting the first channel to presenting a second channel. Responsive to detecting the threshold mismatch, the system thus discontinues channel-specific action with respect to the first channel. For instance, the system could discontinue superimposing of first-channel-specific content on the presented media content and perhaps start superimposing of second-channel-specific content instead.

This disclosure relates to systems and methods for collecting, integrating, processing, distributing, and analyzing spatial and/or spatio-temporal information associated with a variety of data sources and/or locations. In some embodiments, systems and methods described herein allow for collection and integration of information included in one or more spatial and/or spatio-temporal data streams and/or other related information that may be utilized in connection with one or more analytical processes. In certain embodiments, the disclosed embodiments may allow a user to, among other things, interact with spatio-temporal information associated with a variety of diverse data sources, generate visualizations using such data, and/or perform desired analytical queries based on the data.
