Abstract: There are provided, in a clock generator for generating a plurality of output clock signals, an apparatus and method for synchronizing the clock generator to an input reference clock in the presence of a jittery input clock provided to the clock generator from a PLL. The clock generator and the PLL each have a divider with the same ratio. The apparatus includes a synchronizer (205) and a state machine (210). The synchronizer receives the input reference clock and the jittery input clock, and generates there from a synchronized input clock signal with respect to the jittery input clock. The state machine receives the synchronized input clock signal and the jittery input clock, synchronizes with the synchronized input clock signal using the jittery input clock, and abstains from a re-synchronizing operation when the jittery input clock has a jitter of up to a pre-defined maximum number of clock widths.

Abstract: An audio/video apparatus such as a television apparatus includes two or more auxiliary audio inputs (AUX1, AUX2, and AUX3) for receiving respective audio signals, an audio output, and a switch arrangement for selecting one of a broadcast audio signal and the auxiliary audio input signals. The audio/video apparatus operates in two modes. In the first mode where the audio/video apparatus is turned on, the switch arrangement selects one of the auxiliary audio input signals and a broadcast audio signal in response to a user command, and in the second mode where the audio/video apparatus is turned off, the switch arrangement selects a pre-determined one of the auxiliary audio input signals.

Abstract: The disclosed embodiments relate to a technique for selecting one of several antennas or channels in a receiver based on the quality of the channel response at each of the antennas in a multicarrier system employing convolutional forward error-correction coding. Channel estimates are computed for each subcarrier and monotonic weights are assigned to each subcarrier based on the relative strength of the channel response for that subcarrier. The monotonic weights are mapped to each bit in a symbol for each subcarrier and bits are de-interleaved, if needed. A sliding window evaluation is performed to determine an overall channel quality metric for each channel. The antenna or channel having the highest overall CQM is selected to receive data.

Abstract: Within a sequential display system, an apparatus performs motion adaptive processing of a pixel signal that controls the illumination of a corresponding pixel. The apparatus determines from the pixel signal whether motion has occurred for at least a predetermined duration. If not, the apparatus processes the pixel signal to cause a substantially uniform distribution of illumination throughout the picture period for the associated pixel. Otherwise, if motion has occurred for more than the predetermined duration, the apparatus processes the pixel signal to cause a substantial confinement of illumination to a limited interval of the picture period.

Abstract: This application describes a method of referencing content in an application. The method comprises, for a content element, creating a reference to the content element and associating that reference with the content element. This enables the content (for example, text or images) to be dissociated from other features related to content; for example, its presentation on the screen. In this way, control over presentation may be achieved separately from control of the content itself. In an example, a Content Provider 402 provides referenced content to an Operator 404. A Programme Provider 400 sends referenced scenarios to the Operator 404. The Operator 404 resolves the reference and sends data for broadcast by the Broadcaster 406.
