摘要： A television on a chip (TVOC) system that provides a cost effective approach for providing television functionality on a single integrated circuit chip is disclosed. A TVOC includes the functionality necessary to receive and display television signals in a variety of input and output formats. A TVOC can be used in set-top boxes for cable and satellite television, or directly within a television. All functionality provided can be provided on a single integrated circuit. TVOC includes a data transport module, an IF demodulator, a digital audio engine, an analog audio engine, a digital video engine, and an analog video engine. The TVOC also includes three sets of interfaces including output interfaces, control interfaces and ancillary interfaces. Further features and embodiments provide enhanced functionality and increased efficiencies.

摘要： Systems and methods for generation of time-dependent control signals for video signals are provided. A system is provided that includes a set of microsequencers, a programmable combinational logic (PCL) module, shared memory, an arbiter for sharing of memory by the microsequencers, stacks containing registers for microsequencer control, and a control interface. The system can efficiently provide control signals for video signals, implement the MACROVISION copy protection process, and provide other value added features. The method includes accessing programs from shared memory, such that a set of microsequencers can generate flags. These flags are then processed to generate one or more control signals used to support the outputting of video signals including those requiring MACROVISION copy protection.
