摘要： A method and apparatus for selectively reproducing and outputting one or several desired fields when effectuating image reproduction at a 2.5-time high speed from a VTR tape that records thereon images of 60 frames/second as converted by the 2-3 pull-down scheme from 24 fields/second images. This apparatus at least includes a frame change detector unit which detects a frame change of the 2-3 pull-down scheme from the significance of a change in luminance level and/or chromaticity level between a reproduced image and its one-field preceding image, a reference field detector unit for detecting, based on a detection span of the frame change detected by the frame change detector unit, a correspondence relation of recording tracks on the VTR tape versus a repeat period or cycle of 2 fields and 3 fields in the 2-3 pull-down scheme, and a storage unit for storing therein the resultant correspondence relation as detected by the reference field detector unit.

摘要： In order to provide various service types to the users in a case of supplying the contents constituted from multiple resources via broadcast, the following apparatuses are provided. An encryption apparatus (100) encrypts the resources-to-be-encrypted of the contents, stores the encrypted resources in the packets and transmits the packets via broadcast. An encryption portion which encrypts each of contents constituted from multiple resources by applying a corresponding encryption key and generates and transmits packets that store encrypted data or non-encrypted data of the resources. A licensing apparatus (2) providing a license via communication network while the license includes both a license identifier which indicates a broadcast range in which the license is effective and the decryption key provided in correspondence with each of resources-to-be-encrypted. A decryption apparatus (300), by using the corresponding decryption key included in the license received via communications lines, decrypts the encrypted data of the packets received via broadcast.
