Abstract: An electronic device (18). The device comprises an analog (16) interface for receiving an analog waveform. The device also comprises an image screen (20) and circuitry (42) for at times displaying an image on the image screen in response to at least a portion of the analog waveform. The device also comprises a memory (48) for storing firmware code and circuitry (44, 46) for at times writing firmware code in the memory in response to at least a portion of the analog waveform.

Abstract: Systems and method are provided for luma-chroma separation. A demodulator system demodulates a composite video signal to produce at least two baseband chroma signals. A given baseband chroma signal contains chroma information for one of a plurality of video frames comprising the composite signal. A three-dimensional (3-D) comb filter removes luma information from a given baseband chroma signal by combining sets of at least two baseband chroma signals to form a 3-D filtered baseband signal.

Abstract: A video display system, such as useful in video surveillance applications, is disclosed. The system includes a video decoder (20) having a common output data port (27) at which it presents interleaved data streams (DSA, DSB). The interleaved data streams (DSA, DSB) may correspond to multiple scalings of a processed video input signal, for example as received from a surveillance camera (C1, C2, C3, C4). The video decoder (20) also outputs multiple clock signals (CLKA, CLKB), each of which are synchronous with a corresponding one of the interleaved data streams (DSA, DSB). This enables a common data port (27) to output multiple data streams (DSA, DSB), while individual destinations (30A, 30B) of the data streams (DSA, DSB) can continue to operate at legacy clock rates.
