Systems and methods for creating universal microcode images and for reconstructing a microcode image from a universal microcode image are described in the present disclosure. One method, among others, comprises receiving a plurality of microcode images each configured to initialize hardware within an electronic device before the electronic device is booted up. The method also includes separating each microcode image into sections and comparing the sections to determine whether or not two or more sections contain identical code. The method also includes creating a universal microcode image from the sections that are unique.

A method for an interactive media services system (11) is provided for implementing a plurality of media to a user through an interactive media services client device (16). The client device is coupled to a programmable media services server device. The method of the present invention includes implementing an interactive media guide. The interactive media guide is presented by the client device to the user. A system operator is provided with an interface to the programmable media services server. The interface for the system operator provides control options to allow the system operator to configure a plurality of catalogs for the interactive media guide. The interface additionally provides control options to allow the system operator to configure a procedure for dictating the manner in which the plurality of catalogs are stored and distributed to a plurality of the client devices. The system further provides an ability to keep all data referenced by said plurality of catalogs in a central database of a plurality of records such that repetitive data does not exist across more than one of said plurality of catalogs and a plurality of sections within said plurality of catalogs.


An embodiment of the present invention provides a system and method for adaptive video decoding. A method for adaptive video decoding includes determining whether a resource constrained mode is to be initiated, and responsive to a determination that the resource constrained mode is to be initiated, initiating the resource constrained mode, including foregoing the decoding of portions of received video input. For example, adaptive video decoding may include foregoing the decompression and reconstruction of selected video frames during intervals of high demand for memory and/or bus bandwidth resources.

The present invention is directed towards a frequency modulated (FM) burst mode optical system that allows optical signals having a common wavelength provided by a plurality of FM burst mode optical transmitters to be passively combined onto a single optical fiber. A single FM optical receiver receives the combined signals and processes them accordingly. Each FM burst mode optical transmitter includes an FM modulator, is carrier detect circuit and a laser. The FM modulator modulates a carrier signal, such as a 1.21 GHz signal, with received reverse electrical signals. When a subcarrier signal is detected o the carrier detect circuit, the laser is turned and the frequency modulated carrier signal is used to intensity modulate a laser to provide an optical signal. Due to the burst-mode transmission of optical signals, the optical signals can be passively combined and transmitted to a single optical receiver.


The present invention is suitable for use in a multi-encrypted system that dynamically allocates stream identifiers in a second stream depending upon the identifiers in a first stream. The first stream is monitored and counters are incremented with the presence of an identifier. The count for each of the counters is then received. Using the count, a control processor then assigns or revises identifiers in the second stream.

An embodiment of a system for securing media content includes a digital media device comprising a memory associated with a secure element. The memory contains a private key and storage for at least one group key. The private key is used to decrypt transmissions from a remote access control system that are encrypted by a corresponding public key. The digital media device further comprises logic configured to respond to a first message received from the remote access control system encrypted by the public key and including a first group key, the logic responding to the first message by decrypting the first group key and storing the first group key in the memory of the secure element. The digital media device further comprises logic configured to decrypt a content key with the first group key. The content key is used to encrypt media content stored on a medium accessible by the digital media device.

A system that maps media content information to an interactive program guide displayed on a screen includes, among other things, a memory with logic, and a processor configured with the logic to display at least one personal video recording display channel in the interactive program guide. The processor is further preferably configured with the logic to display media content instance listings in the personal video recording display channel for corresponding media content instance recordings.

Included are systems and methods for performing an internal operations test to a set top terminal (STT). At least one embodiment of a method includes creating a test pattern for testing video functionality of the STT, sending the created test pattern to a digital encoder, and converting the test pattern to an analog signal.


The present invention is suitable for use in a multi-encrypted system that dynamically allocates stream identifiers in a secondary overlay stream depending upon the identifiers in a primary encrypted stream. The primary encrypted input stream is monitored to determine the presence of all identifier values. Once the identifier values are determined, the values are stored in an allocation table and marked as in-use to ensure that these identifier values are not allocated to any of the secondary overlay streams. The primary encrypted stream is monitored and the allocation table is updated continuously to detect any changes or conflicts to the identifier values, and the secondary overlay streams are dynamically updated accordingly.
