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.

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.

In a method and system for component sync detection and alignment, the Y/G channel is used as a master channel from which the vertical and the horizontal syncs are detected by a master sync generator. The master sync generator determines a fast and slow slice level for generating a rough and a fractional detection of the vertical sync and the horizontal sync and also generates a master sync timing window signal. A slave sync generator aligns the Pb/B and Pr/R channels to the Y/G channel by making use of the vertical, horizontal, and timing window sync signals produced by the master sync generator and by generating a slave slice level to detect the vertical and horizontal syncs in the slave channels. Positional differences in the alignment between the master channel and the slave channels are determined and stored for use in subsequent frame alignment.

A system and method for efficiently detecting and decoding valid teletext message sequences is provided. A system is provided that includes a correlator, a sine wave generator, two time window generators, a phase detector, a framing code search engine, and a match filter. The method includes determining the phase of the run-in burst of a teletext message sequence, identifying the framing code location, deciding whether the teletext sequence is valid, and decoding the teletext data for display.
