Systems and methods are presented for reducing network traffic when retrieving media guidance data. For example, a media guidance application receives a first user selection to display a group of media asset identifiers (e.g., video-on-demand listings) and retrieves detailed information from a remote server relating to the media asset identifiers to display to a user. The media guidance application then may receive a user selection to display a second group of media asset identifiers (e.g., purchased media assets). If any of the media asset identifiers are common to both groups, then the media guidance application already obtained the detailed information and the detailed information does not need to be retransmitted in order to be displayed. Thus, the media guidance application only retrieves detailed information for media asset identifiers unique to the second group of media asset identifiers (e.g., they are only on the purchased media asset list).

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 generating a directory table identifying one or more LLS tables to be broadcast and sending the directory table in a broadcast stream of the one or more LLS tables. In various embodiments, broadcast service signaling may include calculating a cyclic redundancy check (CRC) code for, generating a hash value for, and/or applying a digital signature to one or more LLS tables in a broadcast stream.

System and devices for live captioning events is disclosed. The system may receive event calendar data and a first plurality of caption files and preselect a first caption file based on the event calendar data. The system may then access an audiovisual recorder of a user device, and receive a first feedback from the recorder. The system may then determine whether the first caption file matches the first feedback. When there is a match, the system may determine a first synchronization between the caption file and the feedback. When there is no match, the system may determine if there is a match with a second caption file of the first plurality of caption files and determine a second synchronization. When the second caption file does not match, the system may receive at least a third caption file over a mobile network and determine a third synchronization for display.

Provided is a display device including: a display; a communicator; a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory, to perform control to extract a video fingerprint from current content being displayed on the display, transmit the extracted video fingerprint to a server, receive, from the server, a first response comprising a matching result of the extracted video fingerprint and video fingerprints stored in the server, extract an audio fingerprint from the current content being displayed on the display in case that the extracted video fingerprint matches a plurality of video fingerprints stored in the server according to the first response, transmit the extracted audio fingerprint to the server, and receive, from the server, a second response comprising a matching result of the extracted audio fingerprint and audio fingerprints stored in the server.

In some embodiments, a method receives a request from a client device. The request includes location information for an update to a media presentation description for a media presentation. The method uses the location information to determine that the client device has not received a first segment based on the location information. The media presentation description is currently sending updates for a second segment. The location information is used to identify that the update to the media presentation description should include the first segment and the second segment. The method sends an instance of the media presentation description that includes update information for the first segment and the second segment to update a stored version of the media presentation description for the client device.
