An embodiment of the present invention includes a method of providing a non-uniform distribution of decoupling capacitors to provide a more uniform noise level across the chip. Leads on a packaged semiconductor chip are grouped into two or more regions. Types of leads needing decoupling capacitors are grouped into lead categories. For each region, there may be one or more lead categories therein. One or more decoupling capacitors are preferably assigned to each lead category in each region. Calculations may be performed to estimate a desired capacitance for each decoupling capacitor for each lead category in each region. When a chip has different components operating at different switching frequencies, different voltages, and/or different switching currents, the distribution of the decoupling capacitors will likely be non-uniform to provide a more uniform noise level across the chip, as compared to a uniform distribution of decoupling capacitors for the chip.

A video streaming network having a server and a client and the client includes a buffer that can be dynamically changed in response to changing communication channel conditions. The client initially allocates a portion of its system memory to be a video buffer based on a test procedure. During transmission of a video work from the server to the client, the server sends a plurality of video packets to fill the client's buffer. The client then retrieves the video data from its buffer and plays the video content on the display. The server, at appropriate times in a coordinated fashion, sends more video packets to top off the video buffer so that the buffer does not run dry. If the amount of data to be played fails to comport with a given set of criteria indicative of communication problems, the client increases the size of its buffer. The size of the buffer also can be dynamically reduced.

A digital television (DTV) data format converter of a system automatically detects whether a serial data stream includes parity data and converts the serial DTV data stream to a parallel DTV data stream. The DTV data format converter transmits the parallel DTV data stream converted from the serial DTV data stream in accordance with a first conversion protocol if the serial DTV data stream includes parity data. If the serial DTV data stream does not include parity data, the converter transmits the parallel DTV data stream converted from the serial DTV data stream in accordance with a second conversion protocol. In this way, the converter accommodates a serial DTV data stream with or without parity data. The DTV data format converter may be implemented in the form of a peripheral component interconnect (PCI) card, permitting compatibility with computer systems and other PCI-based systems. The DTV data format converter may include a receiver block, a transmitter block, and a buffer.

In audio source device the provides a digitized audio signal without volume information, apparatus is coupled to the analog audio conductors to determine the amplitude of the analog signals and therefore the volume of the resulting from the application of the analog audio signals to output apparatus such as speakers. The determination of the amplitude of the analog signals provides indicia of the volume resulting from the analog signals. This amplitude is then digitized and combined with the audio digital signal being transported. The output resulting from the playing of the digitized audio signals can in this manner have a volume dependence that is consistent with the volume of the analog audio signals.

A consumer electronics device includes a universal control logic unit to interface a plurality of input controls, a display and an antenna to a host system via a bus. The host system is located within a shielded enclosure, while the remaining components (e.g., input controls, display, antenna, universal control logic) are located outside the shielded enclosure. Because a single bus preferably is used to interface the various input/output components located outside the shielded enclosure to the shielded host system, the host system can be more easily and effectively shielded than if numerous separate electrical lines and busses were used to directly connect the various input/output devices to the host system.

In order to protect two inter-connected circuits, each powered by different power rail, a circuit is placed between the power supply and the associated power rail. The circuits for both rails are coupled. In this manner, potentially component-damaging power transients are prevented from reaching the power rails. In addition, the power rails are prevented from being separately activated. The extension of the present circuit to more than two power rails is described.

An audio circuit for a computer includes a bidirectional modem connection, a microphone input, first and second audio output channels, and an audio synthesizing circuit arranged to produce first and second synthesized audio channels. In a first mode of operation the first synthesized audio channel is applied to the first audio output channel and the second synthesized audio channel is applied to the second audio output channel. In a second mode of operation the first and second synthesized audio channels are combined into a monotonic signal and applied to the second audio output channel, and audio signals from the bidirectional modem connection are applied to the first audio output channel.

A computer system has a speaker, a unit having a central processor, a monitor separate from the unit, a video cable connecting the unit to the monitor, and a volume control for the speaker, the volume control being mounted in the monitor. Circuitry in the unit responds to the volume control by adjusting the volume output of the speaker.
