Abstract: Systems, apparatuses, and methods are described for protecting the integrity of a playlist, and/or for determining whether a playlist has been altered. The playlist may comprise references to segments of multiple content types. The references may be obfuscated, and/or confirmation data may be used to detect playlist alteration.

Abstract: In one embodiment, a method comprises determining ad placement times for each of a plurality of associated streams. The method also comprises determining an ad selection request time for each of a plurality of ad selection requests based on a cumulative effect of any other ad selection requests occurring at substantially the same time as the determined ad selection time. Each of the plurality of ad selection requests corresponds to one of the plurality of ad placement times.

Abstract: Phone-based remote media system interaction is described. A content distribution system provides a telephone-based voice menu system that enables a caller to select a media system control command. The content distribution system then causes the media system control command to be executed in association with a remote media system associated with, or specified by, the caller.

Abstract: In one embodiment, a method comprises determining ad placement times for each of a plurality of associated streams. The method also comprises determining an ad selection request time for each of a plurality of ad selection requests based on a cumulative effect of any other ad selection requests occurring at substantially the same time as the determined ad selection time. Each of the plurality of ad selection requests corresponds to one of the plurality of ad placement times.

Abstract: In one embodiment, a method can include: (i) receiving a placement opportunity in an ad decision manager (ADM); (ii) sending a request to an ad decision server (ADS); (iii) receiving a conditional response from the ADS, wherein the conditional response includes one or more conditional ads; and (iv) selecting from among the one or more conditional ads.

Abstract: CAM-based search engines may be configured to support multiple databases within a CAM core. These databases may represent tables for different applications, which can be searched sequentially in response to a single indirect instruction that is loaded during a control cycle. The databases to be searched may be identified by a multi-database search instruction that is loaded during a single data cycle, which may overlap with the control cycle. In some cases, the databases may be searched using variations of a primary search key, so that it is unnecessary to repeatedly load the entire search key across a network interface for each search operation within a respective database. Instead, shorter replacement key segments may be loaded for each of a plurality of the search operations and these replacement key segments may be combined with one or more segments of the primary search key in the CAM core to define a desired search key for a respective search operation.

Abstract: CAM-based search engine devices operate to reduce the occurrence of duplicate learned entries within a CAM database when processing search and learn (SNL) instructions. A search engine device may be configured to support processing of first and second immediately consecutive and equivalent SNL instructions as a first SNL instruction and a second search and search instruction, respectively. This processing is performed in order to block an addition of a duplicate learned entry within a database in the search engine device. The search engine device may also be configured to selectively block processing of the second SNL instruction as a second search and search instruction in response to detecting the database as full when the first SNL instruction is processed.

Abstract: An integrated circuit chip includes a search engine including a content addressable memory (CAM) configured to produce CAM indices responsive to search instructions provided to the search engine. The search engine further includes an index translation circuit operatively coupled to the CAM and configured to provide translation of the CAM indices to another memory space, such as from an absolute index space associated with the CAM to a memory space associated with a database within the CAM or to a memory space of a device external to the chip, such as a command source or external SRAM.

Abstract: Integrated search engine devices include a content addressable memory (CAM) core that is configured to support at least one database of searchable entries therein and a control circuit. The control circuit is configured to support reporting to a command host of data identifying entries that have been aged out of the at least one database and/or entries that have exceeded an activity-based aging threshold. The control circuit is further configured to support age reporting that is programmable on a per entry basis within the at least one database.

Abstract: CAM-based search engines and packet coprocessors include control logic that supports direct reads of information that summarizes the done status of multiple contexts being handled by the search engine device. This done status information may be maintained in dedicated registers that are configured to support high bandwidth utilization from a data port of the search engine device. The control logic may also be configured to generate interrupts or asynchronous signals that notify an issuing command source of context completion.
