Abstract: Various embodiments relating to reducing memory bandwidth consumed by a continuous scan display screen are provided. In one embodiment, scoring criteria are applied to a reference image of a first image format having a first bit depth to generate an image conversion score. The scoring criteria are based on a histogram of one or more characteristics of the reference image. If the image conversion score is greater than a threshold value, then the reference image is converted to a modified image of a second image format having a second bit depth less than the first bit depth, and the modified image is scanned onto the continuous scan display screen. If the image conversion score is less than the threshold value, then the reference image is scanned onto the continuous scan display screen.

Abstract: Various embodiments relating to reducing memory bandwidth consumed by a continuous scan display screen are provided. In one embodiment, an indication of a static image period of a continuous scan display screen is determined. A reference image of a first image format having a first bit depth is converted into a modified image of a second image format having a second bit depth that is less than the first bit depth. During the static image period, the modified image is scanned onto the continuous scan display screen.

Abstract: Disclosed are exemplary techniques for compressing ATM cells by substituting reduced headers for the original headers. A header table may be maintained at the transmitting end whereby headers are stored in table entries based on a table index generated from a hash function applied to the headers. A copy of the header table may be maintained at the receiving end and may be updated by populating idle cells with header table contents. Upon receipt of a reduced ATM cell at the receiving end, the reduced header may be replaced with a full header obtained from the copy of the header table maintained at the receiving end. The present invention further provides techniques for registration and management of hash collisions.

Abstract: Improving performance of DSL modem under impulse noise is disclosed. A method of improving a performance of a digital subscriber line (DSL) modem having an impulse noise of long duration includes assigning a value to each of framing parameters based on a rate adaptation algorithm which considers a signal to noise ratio (SNR) of a channel coupled to the DSL modem and a number of constraints applied to the DSL modem. The method also includes generating another set of values of the framing parameters maximizing an impulse noise protection (INP) of the DSL modem while meeting the number of constraints based on a limited set of possible values of the redundancy bytes per Reed Solomon codeword (Rp) of the framing parameters and a limited collection of possible values of the interleaver depth (Dp) of the framing parameters.

Abstract: A system and method for ATM header compression for DSL links is provided. One embodiment, among others, for compressing ATM headers for communication across an ATM network involves transmitting an initial full ATM header to a receiver in the ATM network. Thereafter, when data payloads are available for transmission, the ATM header that corresponds to the data payload is compressed by either a differential technique, dictionary technique, or a multi-cell technique. The compressed ATM header and the data payload are then communicated over the ATM network to the receiver, wherein the receiver is enabled to interpret the compressed ATM header accordingly. By compressing the ATM header, a greater number of ATM cells may be communicated in the ATM network than if the ATM header were communicated in an uncompressed format.
