Abstract: Methods and systems are described for improving a data at a receiver using one or more signal peak detectors. A signal is received having an initial signal level from the transmitter, the signal having a long bit and a short bit. The initial signal voltage of the signal is measured using a signal peak detector. A pre-emphasis value is determined using the signal voltage and is communicated to the transmitter, causing the transmitter to transmit the signal using an adjusted signal level. A second signal voltage of the initial signal is measured using a second signal peak detector, the second signal voltage being used to determine the pre-emphasis value. In another embodiment, a state machine having data relating to appropriate pre-emphasis is used in determining the pre-emphasis value. In another embodiment, one peak detector is used to measure the long bit and another peak detector is used to measure the short bit. In another embodiment, the signal does not have associated link training data.

Abstract: A ring oscillator in a receiver in a multimedia network is adjusted to compensate for factors that may decrease its accuracy over time using a link training signal from a transmitter device in the network. An incoming signal having a known frequency is received at a receiver or sink device from a transmitter, the signal may be a link training signal used for configuring a link between the two devices. In the receiver, an internally generated clock signal is created, the signal having an internal frequency. The incoming signal and the internally generated clock signal are input into a frequency detector which outputs frequency comparison-based data. The internal frequency is based on the comparison-based data such that it is adjusted to be closer to the known frequency of the incoming signal.

Abstract: Methods and systems for transmitting video pixel data from a transmitter component, such as a controller, to a receiver within a monitor are described. Video data is received at a transmitter at an incoming pixel rate based on a pixel clock. The data is transmitted to the receiver at a link symbol clock rate and is drained from the receiver at the pixel clock rate, which is regenerated by the receiver using the link symbol clock frequency, an M video value, and an N video value. The M video value (Mvid) is determined by the transmitter based on the incoming pixel rate and the N video value (Nvid) may be constant. An accumulator is used within the transmitter to ensure that the transmitter and receiver create a balanced system.

Abstract: A sink device having a display panel capable of performing a video frame self-refresh as directed by a source device is described. A source determines that a video frame will persist (i.e., remain the same). In this situation, the frame data does not need to be repeatedly transmitted over a main link between the source and sink devices. The main link can be turned off and transmission can cease for a certain time thereby reducing power usage by the devices or system as a whole. The source ensures that the last frame transmitted to the sink is correct by performing CRC checks and then instructs the sink, via certain bit settings in a video status indication symbol, to store the last transmitted frame in the sink's local buffer and use that frame to refresh the panel. The source can then disable the self-refresh when the frame changes.
