    Abstract: 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.

    Abstract translation: 提出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。 可以指定在使用第一加密方案保护多个电视频道的第一电视频道的同时通过使用第二加密方案加密的第二ECM来保护的多个电视频道中的第二电视频道。 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。

    Abstract: Various arrangements are described for skipping portions of content, such as commercials, from a broadcast television program. The programming content is presented at a reduced presentation rate with the broadcast content being buffered as received. The reduced presentation rate may be less than a broadcast rate at which the content was originally intended to be output for presentation. One or more undesired portions of content may be skipped due to the reduced presentation rate. Commercials may be tagged by a television service provider.

    Abstract translation: 描述了用于从广播电视节目中跳过诸如商业广告的内容的部分的各种布置。 编程内容以降低的呈现速率呈现，广播内容被缓冲为接收的。 缩小的呈现速率可能小于最初旨在输出内容以用于呈现的广播速率。 由于降低的呈现速率，可能会跳过一个或多个不期望的内容部分。 商业广告可能被电视服务提供商标记。

    Abstract: 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.

    Abstract translation: 提出了同时解扰多个电视频道的各种布置。 机顶盒可以接收第一多个电视频道作为加扰的数据分组。 可以访问先前接收的本地存储的网络信息表，其将多个电视频道中的每一个与由分组标识符指示的相同的授权控制消息相关联。 可以接收具有相同分组标识符的授权控制消息。 可以使用智能卡来解密具有相同分组标识符的授权控制消息，以获得第一控制字和第二控制字。 可以使用第一控制字和第二控制字对与多个电视频道对应的加扰的数据包进行解扰。 这些电视频道可以被存储和/或输出以由机顶盒呈现。
