A mutual authentication method in a Downloadable Conditional Access System (DCAS) is provided. The mutual authentication method may receive authentication-related information about authentication between an authentication unit and a security module (SM) from a Trusted Authority (TA), generate an authentication session key using the authentication-related information, transmit the authentication session key by the authentication unit to the SM through a Cable Modem Termination System (CMTS), and control a Conditional Access System (CAS) software to be downloaded to the SM from the authentication unit, when the authentication is completed by the authentication session key.

An array or moat isolation structure for eDRAM and methods of manufacture is provided. The method includes forming a deep trench for a memory array and an isolation region. The method includes forming a node dielectric on exposed surfaces of the deep trench for the memory array and the isolation region. The method includes filling remaining portions of the deep trench for the memory array with a metal, and lining the deep trench of the isolation region with the metal. The method includes filling remaining portions of the deep trench for the isolation region with a material, on the metal within the deep trench for the memory array. The method includes recessing the metal within the deep trench for the memory array and the isolation region. The metal in the deep trench of the memory array is recessed to a greater depth than the metal in the isolation region.
摘要:
A storage medium which stores catalog information and a catalog information recording and/or playback apparatus and method therefor. Using the method, catalog information including a still picture and additional information together with audio data are recorded on a storage medium such as a digital versatile disk (DVD), which is an optical record storage medium, and the catalog information is played back during playback of the audio data, to thereby provide various information on the audio data. Also, the apparatus includes a buffer memory for catalog playback which maintains a predetermined standard and compatibility, and is capable of real-time reading during playback of the audio data, and automatically plays back the catalog content, corresponding to the playback state of the audio data, when there is no additional selection of a user.
摘要:
A method of operating a headend system for a downloadable conditional access service, the method including: receiving, by an Authentication Proxy (AP) server, basic authentication information from a Downloadable Conditional Access System (DCAS) host, the basic authentication information being required to authenticate the DCAS host; transmitting, by the AP server, the basic authentication information to an external trusted authority device which authenticates the DCAS host; generating, by the AP server, a session key for encrypting/decrypting a secure micro client using a session key sharing factor; obtaining, by the AP server, download-related information of the secure micro client from a DCAS Provisioning Server (DPS); and commanding, by the AP server, an Integrated Personalization System (IPS) server to download the secure micro client to the DCAS host based on the download-related information, the secure micro client being encrypted by the session key.

An information storage medium which stores data structures supporting multi-angles includes clip AV streams for respective angle data of multi-angle motion picture data. As additional information for each clip AV stream, clip information is recorded on a separate storage area from that of the clip AV streams. The clip information includes jumping-point information for jumping into another angle. Each of the clip AV streams may be recorded in a contiguous recording area, or divided into smaller interleaved units that are interleaved with units of the other clip AV streams.
