Systems, methods, and devices enable a receiver device to determine completeness of low level signaling (LLS) tables received via broadcast transmissions. In various embodiments, broadcast service signaling may include determining whether a received LLS table is a directory table identifying each of a complete set of LLS tables, parsing the directory table, determining whether the directory table is confirmed based at least in part on a digital signature in the directory table, determining whether a complete set of LLS tables is received based at least in part on the identification of each of the complete set of LLS tables in the directory table, and determining available services based at least in part on the complete set of LLS tables before an expiration a repetition time period after receiving the directory table.

A television receiver 101 is connected to two or more wireless terminals via a communication line. A controller 214 and a network I/F 212 in the television receiver 101 send pieces of login information entered from the two or more wireless terminals to the content distribution server and obtain pieces of content list information each generated by the content distribution server based on the pieces of login information. An aggregated content list in which the obtained pieces of content list information are aggregated is generated. The display 210 displays the aggregated content list. The content list information includes content available for viewing on the information terminal connected to the communication line. The aggregated content list includes content available for viewing on the two or more information terminals in which the pieces of content list information are aggregated.

Mechanisms for interpreting queries are provided. In some implementations, a method for interpreting queries is provided, comprising: receiving a search query in a search domain; determining search terms based on the search query; determining, for each of the search terms, whether a search term corresponds to an entity name, wherein the entity name is derived from metadata associated with the search domain; in response to determining that entity names correspond to a portion of the search terms, determining an entity type and an entity score associated with each of the corresponding entity names; determining a remaining portion of the entity names by removing at least one of the matching entity names based on the entity score and contextual information in the search query; and performing a search in the search domain with the remaining portion of entity names, wherein each entity name in the remaining portion of entity names is searched corresponding to the associated entity type.

Systems and methods for efficiently determining that a media asset scheduled to be stored from one content source has been rescheduled to another content source. For example, by examining the contents of data packets received with a media asset which identify the media asset currently being received (e.g., a field in an event information table), a media guidance application executed on a set-top box or other user equipment device may determine in real-time that the media asset scheduled to be stored is not currently being transmitted from the originally-scheduled content source. In response to determining the media asset is not available from the originally-scheduled content source, the media guidance application may search through packets received from other content sources to determine a content source the media asset has been rescheduled to and store the media asset from that content source.

When a viewer is determined to be interested in an advertisement, a media guidance application may identify a second related advertisement to display to the viewer. The second advertisement may be displayed following the first interesting advertisement. To avoid timing issues, media content following the advertisements may be buffered so that the viewer can catch up on the media content without missing anything.
