摘要： Various arrangements for descrambling multiple television channels concurrently are presented. A set-top box may receive a first plurality of television channels as scrambled data packets. A previously-received locally-stored networking information table may be accessed that associates each of the multiple television channels with the same entitlement control message, as indicated by a packet identifier. An entitlement control message having the same packet identifier may be received. A smartcard may be used to decrypt the entitlement control message having the same packet identifier to obtain a first control word and a second control word. Scrambled data packets corresponding to the multiple television channels may be descrambled using the first control word and the second control word. These television channels may be stored and/or output for presentation by the set-top box.

摘要： Various arrangements are presented that may involve receiving from a television service provider, timers that are used to record a managed channel array. Each of these timers define a television channel, a time period, and a date. The received timers may be set at a television receiver. User input may be received that specifies an undesired television channel that is not to be recorded according to the received plurality of timers, the undesired television channel being part of the managed channel array. An amount of storage space for the managed channel array excluding the undesired television channel may be calculated. Storage space may be allocated based upon the calculated amount of storage space for the managed channel array excluding the undesired television channel.

摘要： Various arrangements for encrypting multiple television channels are presented. A first television channel of a plurality of television channels to be protected via a first entitlement control message (ECM) using a first encryption scheme may be designated. The plurality of television channels may be transmitted using a single transponder stream. A second television channel of the plurality of television channels to be protected via a second ECM encrypted using a second encryption scheme while the first television channel of the plurality of television channels is protected using the first encryption scheme may be designated. The first and second ECMs may be transmitted to a plurality of television receivers. Data from the first ECM may be used for descrambling of the first television channel by the plurality of television receivers. Data from the second ECM may be used for descrambling of the second television channel by the plurality of television receivers.
摘要翻译： 介绍了加密多个电视频道的各种安排。 可以指定通过使用第一加密方案的第一授权控制消息（ECM）来保护的多个电视频道的第一电视频道。 可以使用单个转发器流来发送多个电视频道。 可以指定通过使用第二加密方案加密的第二ECM来保护多个电视频道的第二电视频道，同时使用第一加密方案来保护多个电视频道的第一电视频道。 第一和第二ECM可以被发送到多个电视接收机。 来自第一ECM的数据可以用于多个电视接收机对第一电视频道的解扰。 来自第二ECM的数据可以用于多个电视接收机对第二电视频道的解扰。
