Provided is a random backoff apparatus and method for receiving augmented content that may prevent a delay or a down of a server caused by a plurality of receiving terminals accessing a server simultaneously, when a digital broadcasting system provides broadcast-based bidirectional broadcasting services over a communication network. That is, a technology for distributing receiving terminals accessing a server to receive augmented content, or accessing a home page of a corresponding program, based on metadata transferred from the digital broadcasting system to a broadcasting network. In a bidirectional digital method, a number of requests for access to the home page or the augmented content related to the program may be received from receiving terminals at one time. Accordingly, there is a desire for a method of preventing collision caused when a plurality of stations simultaneously access a single wireless channel.

Provided is an apparatus and method for performing intra prediction for an image decoder, in which by use of horizontal/vertical blocks adjacent to image data input from an external device, the intra prediction is performed in parallel with respect to 16&#xd7;16 luminance component and 4&#xd7;4 luminance component of the image data and then with respect to chrominance component, thereby maximizing efficiency of system to not only reduce execution time and hardware cost but also increase processing speed.

Apparatus and method for performing intra prediction for image decoder

The present invention relates to a finite field multiplier used for implementing an encrypting algorithm circuit, thereby minimizing power consumption and circuit area in implementing the finite field multiplier with a LFSR (Linear Feedback Shift Register) structure. The Finite field multiplier of the present invention is an operator performing a modular operation on the multiplication result of two data represented on a polynomial basis in a Galois Field into an irreducible polynomial. The LFSR structure is a serial finite field multiplication structure, and has a merit over an array structure and a hybrid structure in application to systems that are limited in size and power due to its simplicity of circuits and also its capability of being implemented in a small size.
