The invention relates to a television broadcast system comprising a number of television cameras (C1, C2); at least one production unit (12) which is configured to generate a series of production images from the camera images of the number of television cameras (C1, C2) and to issue said images as production signals (S3); a number of analysis modules (A1, A2) which are configured to analyse each individual camera image, to calculate camera-image metadata (M) and an associated camera-image hash value (H) for each camera image and to issue the camera-image metadata (M) and the camera-image hash value (H) for each camera image asynchronously; a synchronisation module (14) connected to the production unit (12) and the analysis modules (A1, A2) and configured to receive the production images from the production unit (12) as synchronously buffered images and to calculate, for each production image, an associated production image hash value (HR). The synchronisation module (14) is also configured to compare production image hash values (RH) and camera image hash values (H), to assign, on the basis of this comparison, the associated camera-image metadata (Mj) of a camera image as production-image metadata (MR) to a current production image (Ri), and to issue the production-image metadata (MR) as synchronously buffered images; a multiplication module (16) connected to the synchronisation module (14) and the production unit (12) and configured to receive the production-image metadata (MR) from the synchronisation module (14) as synchronously buffered images and to receive the production images from the production unit (12) as synchronously buffered images, the multiplication module also being configured: to compensate a time difference between a production image and the associated production-image metadata (MR); to change in the production image, on the basis of the production-image metadata (MR), at least one portion of the production image by means of an augmentation, thus producing an augmented production image; and to issue the augmented production image.

SYSTEMS AND METHODS FOR LINKING SEGMENTS OF MEDIA GUIDANCE DATA FOR EFFICIENT OPERATION OF MEMORY CONSTRAINED DEVICES

Methods and systems for generating segmented media asset identifiers are described herein. The method includes retrieving a first media guidance data segment of a plurality of media guidance data segments. Each segment of the plurality of media guidance data segments includes a plurality of media asset identifiers and is navigationally linked to at least one other media guidance data segment. The method further involves generating for display the media asset identifiers of the first media guidance data segment. While generating for display the media asset identifiers of the first media guidance data segment, a first user input corresponding to navigating to the media asset identifiers of a linked media guidance data segment is received. In response to receiving the first user input, the linked media guidance data segment is retrieved, and the media asset identifiers of the linked media guidance data segment are generated for display.
