Latest Patents
Chak Cheung Ho's latest patents include a "Content access device with polling processor and methods for use therewith." This invention features an interface module that receives a transport stream and outputs a processed transport stream. The device includes an input buffer that buffers the received transport stream and a polling processor that processes the transport stream based on at least one key to generate the processed transport stream. The polling processor operates to descramble individual packets of the transport stream in a plurality of polling slots of a polling loop. An output buffer is also included to buffer the processed transport stream for output by the interface module.
Another significant patent is the "Spurious-free fractional-N frequency synthesizer with multi-phase network circuit." This synthesizer circuit includes a multi-phase network circuit that provides output signals that are at least a 1/(2n+1) fractional version of the input signal. The synthesizer circuit features a phase lock loop (PLL) circuit, with the multi-phase network circuit coupled to the negative feedback loop of the PLL. Additionally, the multi-phase network circuit includes a smoothing circuit that removes any jitter present at the output of the PLL.
