Abstract: A network comprising an authentication network limited to a family dwelling; a content source; and a content receiver. Wherein the content source is configured to transmit encrypted content to the content receiver, and the content receiver can decode the encrypted content only when both the content source and the content receiver are physically connect to the authentication network.

Abstract: A daisy chain device including a first active mode of operation and a second low power mode of operation. In the first active mode of operation the daisy chain device supplies or receives multimedia data containing at least two types of data. In the second low power mode of operation the daisy chain device relays only predefined data types and consumes less power. Wherein the daisy chain connection includes wires and the transmissions in the different modes of operation are over the same wires.

Abstract: Power saving techniques for a device including an active mode of operation for transmitting a first data stream of at least two data types over wires, and a low power partial functionality mode of operation for transmitting a second data stream over a subset of the wires used for transmitting the first data stream. The power saving techniques may utilize different modulation schemes, different throughputs, different symbol rates, or other techniques.

Some embodiments include a first mode for receiving/transmitting a first data stream over wires, and a second low-power partial-functionality mode for receiving/transmitting a low throughput second bidirectional data stream over a subset of the wires, wherein a bi-functional analog front end supports both modes.

Abstract: A method for parallel scrambling of a sequence of serially transmitted digital bits comprises an initializing scrambling step and subsequent scrambling step. The initializing scrambling step comprises the steps of generating a scrambling bit sequence and storing the scrambling bit sequence in a scrambling register. The subsequent scrambling step comprises: storing a sequential group of bits in the same sequence in which they were received, each of the group of bits containing the same number or fewer bits than the scrambling bit sequence; XOR-ing the sequential group of bits with corresponding bits of the scrambling bit sequence in parallel, thereby generating scrambled bits; and shifting the bits in the scrambling register by a number of spaces equal to the number of scrambled bits and subsequently transmitting and storing the scrambled bits in corresponding cells of the scrambling register in lowest ordinal sequence for use in subsequent XOR-ing of a next sequential group of bits.
