An apparatus and method for improving the communication capabilities of computer systems is disclosed. The most preferred embodiments of the present invention use a series of data buffers and data registers to process an incoming high speed data signal. By using the buffers and registers, the incoming signal can be reformatted and manipulated at a much lower frequency than the original transmission frequency. The deserializer of the present invention also samples a greater portion of the incoming data signal than usual to further increase reliability. These various features of the invention provide for a more stable and reliable communication link and will also provide a less expensive solution for serialization/deserialization. The present invention includes a serializer that receives parallel data input from a computer and serializes the data for transmission over a high-speed serial communication link. On the receiving end, the present invention provides a deserializer that can quickly and efficiently transform the serial data back into parallel form for use within the computer system on the receiving end. By utilizing two related clock signals, one clock signal being an integer multiple of the other, a self-synchronizing serializer/deserializer can be created. In addition, by increasing the size of the data sample on the receiving end, the comparisons necessary to retrieve a parallel signal from a serial transmission can occur at a much lower frequency than the frequency of the serial transmission. In the most preferred embodiment, the invention is provided as a integrated solution manufactured on a Peripheral Component Interconnect (PCI) card, thereby allowing the present invention to be easy installed into existing computer systems.

Novel methods and systems for quantization based data embedding and reading in host signals, such as image, audio and video signals. To embed auxiliary data in a host signal, an embedder maps the host signal from a first domain into a mapped signal in a second domain. The embedder performs quantization based embedding of auxiliary data into the host signal using quantizers. The quantizers are adapted such that the relationship between corresponding quantizers in the first and second domains satisfies a predetermined constraint. The mapping improves the robustness of the data embedding method by increasing the chances that the embedded data can be recovered by an auxiliary data reader after modifications. A related embedding method projects the mapped signal unto a vector, and specifically, a pseudorandom vector. It performs quantization based embedding on the projected signal. The use of this projection provides added robustness of the embedded data to noise and other forms of distortion.
