20220046314 | SYSTEMS AND METHODS FOR RETRIEVING SEGMENTED MEDIA GUIDANCE DATA - 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). | 2022-02-10 |
20220046315 | THINNING VIDEO BASED ON CONTENT - In an embodiment, a method of thinning video captured of a scene comprises identifying and retrieving a segment of the video that occupies an amount of space in storage, processing the segment of the video to determine if the scene qualifies as of interest to a potential analysis of the video, and if the scene does not qualify as of interest to the potential analysis of the video, reducing the amount of space in storage occupied by the segment. | 2022-02-10 |
20220046316 | METHODS AND APPARATUS TO DETECT COMMERCIAL ADVERTISEMENTS ASSOCIATED WITH MEDIA PRESENTATIONS - Methods and apparatus to detect commercial advertisements associated with media presentations are disclosed. An example method involves receiving a video frame and detecting a change in box-formatting between the video frame and a subsequent video frame. A transition between the video frame and the subsequent video frame is indicated as a commercial advertisement transition based on the detected change in box-formatting. | 2022-02-10 |
