A method, in accordance with one embodiment, for adjusting a transmission rate of a network device for a transmission based upon network bandwidth utilization on a network comprising transmitting a data stream at a current transmission rate utilizing a first bandwidth allocation; receiving a transmission rate recovery request from a master device on the network; receiving an additional bandwidth allocation from the master device on the network when the current transmission rate is less than an original transmission rate; and transmitting the data stream at an increased transmission rate utilizing a total bandwidth allocation, the total bandwidth allocation including the additional bandwidth allocation and the first bandwidth allocation.

SYSTEM AND METHOD FOR ERROR CORRECTION IN HIGH DEFINITION TV SIGNAL
An input signal such as a HDTV signal is split into a primary signal, which can be decoded if desired, and an secondary signal, which can remain compressed. The primary signal may be delayed and then both signals are transmitted to a receiver. If no error in the primary signal is detected, the primary signal is used to display data. Otherwise, the secondary signal, which arrives before the primary signal and consequently which is available for substitution, is displayed.

METHODS AND APPARATUS FOR OPTICAL WIRELESS COMMUNICATION
The present invention relates generally to methods and apparatus for optical wireless communication, and in particular to wireless optical delivery of a video signal. In one embodiment, a wireless optical video system (100) in which video content (e.g. , DVI or HDMI) is transmitted wirelessly between a digital video source (110) and a display device (150). This wireless optical communication is accomplished using a laser (520), encoded with the digital video data, directed from an optical transmitter (120) to an optical receiver (140). In another embodiment, the data to be communicated includes high- definition video content.
A multiplication engine is described in which a decision threshold engine utilizes a Y-adder powers of two shift table to iteratively generate shift-add combinations. The shift-add combinations are output in a sequence with decreasing levels of contribution wherein the accuracy of the associated multiplication increases up to any desired level of accuracy to meet the requirements of the application. The multiplication engine can be used for generating the combinations either statically or dynamically. One embodiment describes a Y-adder hardware slider table engine in which the shift table is implemented with shifters and adders that can be set for active state or pass through state, and selectively summed to generate a product result directly from the table without the need to combine shift and add hardware.
A CableCARD device for manipulation of a stream of data has an inband data input for receiving a stream of video data from a host, the stream of video data being encrypted and encoded according to a first coding. A decrypter decrypts the encrypted data. A transcoder transcodes the stream of video data to convert the stream of video data to a second coding, producing a transcoded data stream. An encrypter encrypts the transcoded data stream. An inband data output sends the encrypted transcoded data stream back to the host. This abstract should not be considered limiting, since other embodiments may incorporate more, fewer or different elements that those described in this abstract.

SYSTEM AND METHOD FOR PARTIALLY ENCRYPTED MULTIMEDIA STREAM
A multimedia stream head end includes a legacy conditional access (CA) device (20) that fully encrypts the stream using legacy keys. A copy of the stream is sent to a secondary CA device (24) that encrypts only critical packets in the stream using secondary keys to render a partially encrypted stream. The critical packets in the fully encrypted stream from the legacy CA device (20) are obtained and inserted next to the corresponding critical packets in the partially encrypted stream. Thus, only critical packets are encrypted, with encrypted versions being generated by both the legacy CA (20) and secondary CA (24) without the legacy CA (20) knowing which of the packets that it encrypts are "critical".
