Abstract: Methods and apparatus for estimating received error rates. In one embodiment, the estimation of received error rates is conducted in relation to a bus interface such as a high-speed High-Definition Multimedia Interface (HDMI) interface, and the method utilizes corrupted symbols that violate TMDS symbol rules, the corrupted symbols being easily detected and counted. In one exemplary implementation, a symbol error rate (SER) can be estimated from the number of detected invalid symbols. The SER can be used to diagnose the performance of the HDMI interface, and optionally as a basis for selecting or implementing corrective action(s).

Abstract: Methods and apparatus for the safe negotiation of high current for a High-Definition Multimedia Interface (HDMI) active cable assembly. In one embodiment, a method for detecting a Power for Cable Assembly (PCA)-capable source is disclosed, the method including: detecting, by a cable assembly, an assertion of a defined voltage on a power supply pin; forwarding an assertion of a hot plug detect signal pin, by the cable assembly, from a sink device towards the PCA-capable source; detecting, by the cable assembly, a reduction in the defined voltage on the power supply pin for a defined period of time in response to the forwarding; and detecting, by the cable assembly, a re-assertion of the defined voltage on the power supply pin subsequent to the lapse of the defined period of time. PCA dependent cable assemblies and PCA capable source devices are also disclosed.

Abstract: Methods and apparatus for virtual channel allocation within an electronic device. In one exemplary embodiment, the device is a consumer electronics device having multiple camera sensors uses a modified high-speed protocol (e.g., DisplayPort Multi-Stream Transport (MST) protocol) to process camera data via one or more virtual channels. Unlike traditional solutions which rely on an intelligent source device to manage a network of devices, the present disclosure describes in one aspect a network of nodes internal to a consumer electronic device that is managed by the sink node (i.e., a “smart sink”). Additionally, since the full suite of protocol (e.g., DisplayPort) capabilities are unnecessary for certain design scenarios, certain further disclosed simplifications improve performance for sink nodes having very modest capabilities.

Abstract: The present invention provides a method that protects symbol types by characterizing symbols as one of two types—DATA or NON_DATA, generating a symbol characterization bit, placing the symbol characterization bit at both ends of the symbol, and transmitting the symbol with the symbol characterization bits at both ends. Thus, a single byte error may affect a type bit in two consecutive symbols, and will affect one or the other of the type bits in a single symbol, but cannot affect both type bits in a single symbol.
