摘要： A transport stream is encrypted in such a manner that the stream may be processed without requiring encrypted portions of the stream to be decrypted. Thus, an analysis is performed on the stream to determine at least one portion of the stream that is to pass unencrypted, thus enabling the stream to be processed in a manner that bypasses encrypted portions of the stream.
摘要翻译： 传输流被加密，使得流可以被处理而不需要对流的加密部分进行解密。 因此，对该流执行分析，以确定流未经加密的流的至少一部分，从而能够以绕过该流的加密部分的方式处理该流。

摘要： Innovative techniques for identifying and distinguishing content, such as commercials, can be used with means for marking key frames within the commercials to facilitate replacement of commercials and other programming segments in such a way as to provide improved focus and relevance for targeted advertising based on known and/or dynamic conditions. The identification of commercial features can also be used to provide improved trick play functionality while the commercial or other programming is rendered.

摘要： A tuning device uses a counter mode encryption cipher to encrypt counters associated with media content in order to protect the media content when it is sent to requesting device or controller. The encrypted counters are decrypted in order to consume the media content. The controller may send particular direction to the tuning device as to how the media content, encrypted counters, and other associated data are sent to the controller.
摘要翻译： 调谐设备使用计数器模式加密密码来加密与媒体内容相关联的计数器，以便在发送到请求设备或控制器时保护媒体内容。 加密的计数器被解密以便消耗媒体内容。 控制器可以向调谐设备发送关于如何将媒体内容，加密的计数器和其他相关联的数据发送到控制器的特定方向。

摘要： The present invention provides for an interface between two seemingly incompatible and different content protection systems. Accordingly, protected content may be transferred between the respective security kernels of a conditional access (CA) and digital rights management (DRM) systems, while maintaining security of the content and any associated protection information. The transfer and consumption of protected content and the associated content protection information may be achieved by temporarily or permanently binding the respective security kernels of the CA and DRM systems, transcribing content protection information, and potentially transcribing the content.
摘要翻译： 本发明提供了两个看似不兼容的和不同的内容保护系统之间的接口。 因此，受保护内容可以在条件访问（CA）和数字版权管理（DRM）系统的相应安全内核之间传送，同时保持内容的安全性和任何相关联的保护信息。 可以通过临时或永久地绑定CA和DRM系统的相应安全内核，转录内容保护信息和潜在地转录内容来实现受保护内容的传送和消费以及相关联的内容保护信息。

摘要： A communication path is established that allows for communication between a filter graph space and a network driver space in a system. The communication path allows bidirectional communication between a filter graph driver in the filter graph space and a network driver in the network driver space. Addresses of data can be passed from the network driver to the filter graph driver, which allows the filter graph driver to communicate with a filter graph manager as necessary to configure the filter graph space to obtain data from the requested address. The data obtained from the address is then passed from the filter graph driver to the network driver.

摘要： A multi-receiving device receives broadcast transmission signals based on different transmission standards. A determination is made as to a particular transmission standard that is used by a received broadcast transmission signal, and the receiving device is configured as to the particular transmission standard in order to parse or process metadata included in the received broadcast transmission signal.

摘要： Various embodiments provide accurate EPG lineup construction and PVR scheduling for users, regardless of their geographic location. In accordance with the described embodiments, the guide retrieves and aggregates data from multiple available sources, particularly in-band scanning and EPG metadata download. Services are then identified and sorted into logically equivalent groups. Once the services are grouped, in accordance with one embodiment, an analysis is conducted the outcome of which is directed to selecting which services to use for tuning and which services to use for scheduling on a given channel/preset. In addition, various embodiments can, in an automated fashion, assign services to presets/channels, as well as provide a user interface and methods for editing a lineup, modifying tuning information and personalizing presets/channels.

摘要： A modularized broadcast receiver driver architecture includes one or more control nodes, under control of a network module, that perform a series of one or more functions to receive a broadcast signal and extract content information from the signal. None of the multiple control nodes requires knowledge of the network type via which the signal is being received. Rather, a network module is aware of the network type and configures the control nodes to carry out their respective functions.
