Abstract: Common techniques for Motion Compensated Frame Rate Conversion (MC-FRC) suffer from occlusion which, if not taken explicitly into account, causes a visually disturbing artifact known as ‘halo’. To solve this artifact, these regions have to be detected prior to performing interpolation. Several techniques exist to detect occlusion in a frame, but these are based on motion vectors, which are frequently unreliable. The invention relates to a method to detect occlusion by comparing match errors, thereby offering occlusion detection even when the motion vectors are incorrect.

Abstract: A method for encoding first and second data words, which may represent differential data values (e.g., luminance and chrominance difference data values), onto an encoded data word includes: assigning a first code word to a first approximation value for a first data value, and assigning a second code word to second approximation value for a second data value; mapping the first and the second code words onto respective first and second data segments of the encoded data word; determining a first difference value between the first data value and the first approximation value and determining a second difference value between the second data value and the second approximation value; and at least partial mapping a first difference data word representing the first difference value and/or a second difference data word representing the second difference value onto at least one additional data segment of the encoded data word.

Abstract: A device for transport stream processing is provided. The device includes a plurality of data inputs and a transport stream re-multiplexer for receiving a plurality of data streams from the plurality of data stream inputs and multiplexing the data streams into a transport stream. A transport stream processor receives the transport stream, de-multiplexes the transport stream to process one or more of the data streams, and provides the processed data stream to the transport stream re-multiplexer as one of the plurality of data streams.

Abstract: In one embodiment, a network node includes a lookup table configured to store one or more of the following frequency domain bit sequences: i) x010101000110xxxxxxx011000000000; ii) x1011000111000000011011110xxxxxxxxxxxxx0110111001101001010111010; iii) x0011011011111010011101111xxxxxxxxxxxxx0111010010111110000000101; iv) x000000011000100110100100xxxxxxxxxxxxx1011011110000110101011100; and v) x1000010000110111100000110xxxxxxxxxxxxx1100110011101101111110110. The node includes a processing channel configured to generate a preamble including at least one of the frequency domain bit sequences, and a transmitter configured to transmit the preamble and a data packet over a communication channel.

Abstract: The terminating impedance of a networked device in a wired communication channel is controlled to avoid an impedance discontinuity when power is applied and removed from the node or other event occurs that would change the impedance of the signal interface. When the node transmits or receives signals using the communication channel, the transmit or receive device presents a matched termination to the channel. When power is removed or the device is reset, the transmit and receive circuitry is not operational and the matched impedance is therefore maintained by a separate device. The impedance may be varied slowly from a match to a high impedance to allow other devices in the network to adapt to the change in multipath environment that results from the impedance change. Alternatively, the signal interface can be switched to a passive static impedance that is maintained while power is off or the disrupting event occurs.
