Abstract: A system and method for transmitting compressed video. A transmitter receives uncompressed video data from a video source, and compresses it using one or more reference frames. A receiver receives the compressed video data and decodes it, using the same reference frames, to form display data. The reference frames are stored in compressed form in both the transmitter and the receiver. Each frame of display data becomes a reference frame for the decoding of a subsequent frame.

Abstract: A system and method for transmitting frames of video data to a display. Each frame is divided up into blocks, and the data from each of the resulting blocks is coded using temporal reference coding, along with intraframe coding. In one embodiment a difference block is formed by taking the difference between a block in a second frame of a sequence of frames, and a corresponding block, in the same position, in a first frame of the sequence of frames. The difference block is coded using intraframe coding, to form a coded difference block. The coded difference block is transmitted to a display; processing hardware in the display reconstructs the sequence of frames.

Abstract: A data bus and message handling method provide a definitive means of indicating a client-aborted message for data bus systems which employ a message protocol that requires each message conveyed between a client device and an originating device to automatically and atomically include a frame check sequence (FCS). When a message is not to be client-aborted, a ‘good’ FCS is generated by a first method, typically based on the message's data content. However, when a message is to be client-aborted, the FCS is generated by a second method which requires modifying the good FCS value to create a ‘bad’ FCS, preferably using a mathematical means that preserves the uniqueness of the bad FCS to a high degree.

Abstract: A single wire bus communication system comprises a bus wire, a host device, and at least one client device, with each host and client device having pull-up and pull-down transistors to pull the bus wire “high” or “low”, respectively. The system is arranged such that, in response to a “trigger event” that requires responses from multiple client devices simultaneously, the host device enables its pull-down transistor, and each client device disables its pull-down transistor when conveying a “low” logic level onto the bus. To avoid bus contention, each client's pull-up transistor is arranged to conduct more current when enabled than the host's pull-down transistor. Then, one or more of the client devices' strong pull-ups will overcome the single weak pull-down on the bus, thereby enabling numerous client devices to respond to a command that requires a response from multiple clients.

Abstract: A system and method for portable computer battery management using host processing relocates analog and digital components needed to implement the SBDS standard from the battery pack to the computer, which processes the acquired battery data using the host processor. The battery pack requires only battery temperature and voltage sensing circuits, and an interface circuit for conveying the sensed data out of the battery pack. The portable computer includes a circuit which senses current provided to or drawn from the battery. Battery temperature, voltage and current data is provided to the computer's host system, which executes a battery management application program to determine battery status in accordance with the SBDS standard.

Abstract: A rechargeable battery measurement and calibration system for use with a removable battery pack suitably used to power a mobile computer locates current measurement and battery status intelligence outside of the battery pack, thereby reducing the cost, complexity, and power consumption of the battery pack when compared with prior art systems. A system host controls the measurement and calibration of the battery system; the host requests current measurements under both zero-current and non-zero calibration current conditions, with the resulting calibration values enabling linearity errors that might otherwise be present in the current measurements to be totally and easily identified and accounted for in a fuel gauge measurement. The present system complies with the SBS-IF specification for Smart Battery systems.
