摘要： A communication system including a transmitter (1'), a receiver (1'), and a serial link, in which encoded data (e.g., encoded video data and encoded auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, alternating bursts of encoded video data and encoded auxiliary data are transmitted over each of one or more channels of the link. Other aspects of the invention are transmitters for use in encoding data for transmission over a serial link, and methods for sending encoded data over a serial link. In accordance with the invention, the data to be transmitted are encoded using a subset (sometimes referred to as a selected set of code words) of a full set of code words. The selected set of code words is selected such that each stream of encoded data (comprising only using such code words) transmitted over a serial link has a bit pattern that is less susceptible to inter-symbol interference ("ISI") during transmission than is the bit pattern determined by a conventionally encoded version of the same data (comprising not only the selected set of code words but also other members of the full set). Typically, the selected set of code words includes words whose serial patterns (during transmission)have fewer contiguous zeros and ones (and thus are less susceptible to ISI during transmission) than do those code words in the full set that are not selected. In preferred embodiments in which the bits of the selected set of code words are transmitted over a serial link as sequences of rising and falling voltage transitions, the bit pattern of each transmitted stream of the selected set of code words implements DC balancing to limit the voltage drift over time.

摘要： A method of transmitting data is a system including at least one data channe l and a separate clock channel is disclosed. The method involves combining a clock signal to be transmitted on the clock channel with a data signal to generate a combine d clock and data signal. In one embodiment, the data signal has been generated from data words using an encoding scheme that shifts an energy spectrum of the data signal away from an energy spectrum of the clock signal. In another embodiment, the clock signal has a plurality of pulses each having a front edge and a back edge, and the data signal is modulated onto the clock signal by moving at least ones edge (i.e. front or back or both) of the plurality of pulses, thereby to create a combined clock and data signal.

摘要： The system preferably includes a unique transmitter that sends both clock an d data signals over the same transmission line. The receiver uses the same transmission line to send data signals back to the transmitter. The transmitter comprises a clock generator, a decoder and a line interface. The clock generator produces a clock signal that includes a variable position falling edge. The falling edge position is decoded by the receiver to extrac t data from the clock signal. The receiver comprises a clock re-generator, a data decoder and a return channel encoder. The clock re-generator monitors t he transmission line, receives signals, filters them and generates a clock sign al at the receiver from the signal on the transmission line. The return channel encoder generates signals and asserts them on the transmission line. The signal is asserted or superimposed over the clock and data signal provided b y the transmitter.

摘要： The invention is a personal digital network (PDN) comprising hardware configured to transcrypt (decrypting followed by re-encrypting) encrypted content that enters the PDN. Typically, the transcryptionis performed inside the receiving device and the re-encryption occurs before the decrypted content is accessible by hardware or software external to the receiving device. Typically, transcrypted content that leaves the receiving device remains in re-encrypted form within the PDN whenever it is transferred between integrated circuits, until it is decrypted within an outputting device for display or playback or output from the PDN. Typically, the PDN is implemented so that no secret in receiving or outputting device is accessible in unencrypted form to software or firmware within the PDN or to any entity external to the PDN. Other aspects of the invention are methods for protecting content in a PDN a devices for use in a PDN.
摘要翻译：本发明是一种个人数字网络（PDN），其包括配置成对进入PDN的加密内容进行加密（解密后再重新加密）的硬件。通常，在接收设备内执行的转录和重新加密发生在接收设备外部的硬件或软件可访问解密的内容之前。通常，离开接收设备的经过加密的内容一旦在集成电路之间传输，就保持在PDN内的重新加密形式，直到在输出设备内被解密以便从PDN显示或重放或输出。通常，实现PDN，使得接收或输出设备中的秘密不可以以未加密的形式访问到PDN内的软件或固件或PDN外部的任何实体。本发明的其他方面是用于保护PDN中的内容的用于PDN中的设备的方法。

The receiver uses the same transmission line to send data signals back to the transmitter. The transmitter comprises a clock generator, a decoder and a line interface. The clock generator produces a clock signal that includes a variable position falling edge (T0, T1, T3, T4) for pulse with modulation by the data (00, 01, 10, 11). The falling edge position is decoded by the receiver to extract data from the clock signal. The receiver comprises a clock re-generator, a data decoder and a returm channel encoder. The clock re-generator monitors the transmission line, receives signals, filters them and generates a clock signal at the receiver from the signal on the transmission line. The return channel encoder generates signals and asserts them on the transmission line. The signal is asserted or superimposed over the clock & data signal provided by the transmitter.

摘要： A cable including circuitry for asserting information to a user or external device and a system including such a cable. The cable can include conductors, a memory storing cable data, and circuitry configured to respond to a request received on at least one of the conductors by accessing at least some of the cable data and asserting the accessed data serially to at least one of the conductors (e.g., for transmission to an external device). Other aspects of the invention are methods for accessing cable data stored in a cable and optionally using the data (e.g., to implement equalization). The cable data can be indicative of all or some of cable type, grade, speed, length, and impedance, a date code, a frequency-dependent attenuation table, far-end crosstalk and EMI-related coefficients, common mode radiation, intra pair skew, and other information. The cable can include a radiation-emitting element and circuitry for generating driving signals for causing the radiation-emitting element to produce an appropriate color, brightness, and/or blinking pattern.
