Abstract: A system is described that includes an electronic program guide (EPG) data receiver and a media content catalog enhancer. The EPG receiver is configured to receive EPG data from an EPG data provider. The media content catalog enhancer is configured to determine that an item of media content identified by the EPG data comprises new media content and, in response to determining that the item of media content identified by the EPG data comprises new media content, to cause a web crawler to crawl a source website associated with the new media content to obtain information about the new media content and to store the obtained information about the new media content in a database, the database comprising a catalog of media content that is searchable by an end user to identify and access content for playback via an end user device.

Abstract: Methods, systems, and computer program products are provided for obtaining enhanced metadata for media content searches. In one embodiment, computer program logic embodies a metadata receiver and a media content metadata matcher and combiner. The metadata receiver receives program metadata for a plurality of programs from a plurality of metadata sources. The media content metadata matcher and combiner is configured to perform a matching process whereby metadata associated with each of the plurality of programs is compared to metadata of each of the other plurality of programs to determine if the compared programs are the same program and if so, to combine the metadata from each program into a single program including enhanced metadata and store such in a database. A subsequent search for a program corresponding to the stored program returns at least some of the metadata associated with the program, and that enables accessing the program.

Abstract: Methods, systems, and apparatuses are described herein for enhancing metadata of a recorded items of media content stored on a digital video recorder (DVR) associated with an end user. First metadata associated with the recorded item is determined from the DVR. An aired instance of the first media content is determined in program data from an electronic program guide that corresponds to the recorded item. Second metadata associated with the first media content is retrieved from at least one data source based at least on the identifying information. The first metadata and the second metadata are stored in an end user database in association with the end user.

Abstract: Embodiments are described herein for enabling fast and efficient media content searches across a wide variety of content providers using a graph database. For instance, metadata may be collected from different metadata sources. A graph database is generated that stores and organizes the metadata based on attributes of the metadata and the relationships therebetween. For example, each attribute is assigned to a node of the graph database. The nodes may be connected via an edge that represents a relationship between the nodes. Attributes of metadata retrieved from a first metadata source are associated with attributes of metadata retrieved from a second metadata source. When receiving a query, the graph database is traversed for media content items to recommend to a user. The media content items recommended to the user include items from different content providers that are determined based on the traversal of the nodes of the graph database.

A DSP performs a delay profile analysis operation on the signal resulting from the iFT operation.

Abstract: A system for mapping control and user data includes a direction scanner, an address calculator, a collision detector, a buffer, and a mapper for mapping control and user data from a first memory to a second memory. The direction scanner determines the highest priority value of to a code word index. The address calculator calculates start and end addresses of the highest priority value. When an address from an address range, defined by the start and end addresses, is already mapped to other control data, the collision detector detects a collision and generates feedback data. The address calculator outputs modified start and end addresses based on the feedback data. When no collision is detected, the address calculator outputs the modified start and end addresses to the buffer. The mapper then maps the control and user data to the modified start and end addresses in the second memory.

Abstract: A system for storing pre-distorted output samples in a memory includes a sample counter, a programming interface module, and a comparator. The sample counter counts the pre-distorted output samples, generates a dynamic count value, receives a capture counter status signal, and generates a first count value. The programming interface module receives and outputs the first count value, an offset value, and a capture control signal, and generates a first interrupt signal. The comparator receives the first count value, the offset value, the dynamic count value, and the capture control signal, generates a final value, compares the final value with the dynamic count value, and generates a trigger signal when the final value equals the dynamic count value based on the capture control signal. The trigger signal initiates the storing of the pre-distorted output samples in the memory.

Abstract: A system for calibrating a power amplifier (PA) includes a memory, a processor, a digital pre-distorter (DPD), and a data converter. The DPD includes a programming interface module, a pattern generator, a multiplier, and a pre-distorter module. The multiplier multiplies reference baseband stream data from the memory with pattern coefficient data generated by the pattern generator to generate shaped reference baseband stream data. The pre-distorter module generates pre-distorted shaped reference baseband stream data. The PA receives a low-power reference radio frequency (RF) signal corresponding to the pre-distorted shaped reference baseband stream data and generates a high-power reference RF signal.

The DPD controller generates antenna select, stream select and stream routing signals indicative of selection of antennas, the first and second LUTs, and input signals. The DPD controller configures the DPD to share the multipliers and the first and second LUTs between multiple antennas by providing the antenna select signal to the antenna select mux, the stream select signal to the stream select mux, and the stream routing signals to the first and second dynamic routing logic units.

The second FIR filter receives a Q input signal and generates third and fourth intermediate output signals based on the third and fourth values for the I and Q channels, respectively. The first and second adders receive the first and second, and the third and fourth intermediate output signals, respectively, and generate compensated I and Q output signals for the I and Q channels.
