Abstract:
Systems and methods for determining the location of advertisements in multimedia assets are disclosed. A method includes obtaining an audio signature corresponding to a time period of a multimedia asset, identifying a match between the obtained audio signature and one or more stored audio signatures, comparing programming data of the multimedia assets of the obtained audio signature and the matching audio signatures, and determining whether the time period of the multimedia asset contains an advertisement based on the comparison of the programming data of the multimedia assets of the obtained audio signature and the one or more matching audio signatures. Another method includes identifying matches between a plurality of obtained audio signatures and a plurality of stored audio signatures, and determining whether consecutive time periods of the multimedia asset contain an advertisement based on a number of consecutive matching audio signatures of the plurality of stored audio signatures.
Abstract:
A method is provided for encoding a video program that includes receiving a video program to be encoded and evaluating the program with a profile is selected from among a plurality of profiles stored in a database. Each of the plurality of profiles include program attributes associated with one or more video programs and information pertaining to one or more static graphical elements that overlay content in the one or more video programs. The selected profile is applicable to the video program to be encoded. At least a portion of the video program is caused to be encoded based at least in part on the information in the selected profile. The encoded portion of the video program is evaluated to assess an accuracy of the selected profile and, based at least in part on the evaluation, a confidence level is assigned to the selected profile.
Abstract:
Particular embodiments take first screen media assets and can derive second screen appropriate media assets. Then, particular embodiments may determine a target application for the second screen media assets. Layout characteristics for the target application is determined. Particular embodiments correlate the layout characteristics and the second screen media assets to select a second screen media asset for the target application. The correlation may generate scores based on the second screen media assets and the layout characteristics to determine a best fit of a second screen media asset for the target application. Then, the second screen media asset may be transcoded based on the characteristics of the target application or target device. After transcoding, particular embodiments may create a view of the second screen media asset in the target application, such as an overlay of the second screen media asset over a screen capture of the target application.
Abstract:
Particular embodiments use a multi-view coding (MVC) extension to provide second-screen content along with the first-screen content. In one embodiment, a head-end multiplexes the first-screen content with the second-screen content into a single content stream. The second-screen content is added to the video stream according to the MVC extension requirements. At the user end, such as at a gateway, instead of sending the first-screen content and second-screen content to the first-screen device, the gateway de-multiplexes the first-screen content and the second-screen content. The gateway can then send the first-screen content to the first-screen device while caching the second-screen content. When the gateway determines that the second-screen content should be displayed on the second-screen device, the gateway can send the second-screen content to the second-screen device for display on the second-screen of the second-screen device.
