摘要： A method and apparatus for downloading ancillary program data to a DVR. An embodiment allows multimedia device users to select programs to record or download movie or music over a network, such as the Internet, from a content provider. The system automatically downloads and stores ancillary program data that is directly related to, and associated with, a program that has been selected for recording or content requested for download. When a user selects a program to view the user is offered the opportunity to browse ancillary program data associated with the program and view an ancillary program data. The service can charge the content provider or an advertiser for each time their ancillary program data is viewed by a user. The ancillary programming is deleted when the associated recorded program is deleted.

摘要： A method, non-transitory computer-readable storage medium, and reception apparatus for extracting metadata, and an information providing apparatus for providing the metadata. The method for extracting metadata includes processing, by circuitry of the reception apparatus, content that includes the metadata embedded therein. The metadata is embedded as a watermark in a first portion of a video frame of the content. The circuitry determines symbol values of the watermark from the video frame based on luminance values in pixels of the first portion of the video frame of the content to extract the metadata. At least one of the luminance values is less than 16.
