MPEG-4 dan FLV adalah contoh  format extension file video. MPEG-4 adalah suatu metode untuk melakukan kompresi video. Pada prinsipnya, sebuah gambar bergerak adalah sekumpulan frame yang mengalir dengan cepat, di mana setiap frame adalah gambar dengan kata lain, sebuah frame adalah kombinasi pixelpixel, dan sebuah video adalah kombinasi fisik dari frame-frame yang dikirim secara bergantian. FLV adalah video dengan format flash movie yang digunakan di internet. Algoritma Huffman menggunakan Huffman Coding ketika endcode data sebagai pola biner, biasanya menggunakan sejumlah bit yang tetap untuk setiap simbol. Algoritma kompresi LZ77 melakukan kompresinya dengan mengganti porsi data dengan suatu referensi untuk menyamakan data yang sudah dilewati oleh encoder dan decoder. Algoritma ini menggunakan suatu sliding window yang terdiri dari search buffer dan look-ahead buffer. Search buffer digunakan sebagai kamus, sedangkan look-ahead buffer merupakan buffer yang berisi string yang akan dikompresi.

This study aimed at analyzing the cognitive dimension based on Revised BloomTaxonomy in reading questions in Look Ahead an English Course for Senior HighSchool Level 1, 2, & 3. This study used quantitative research design. The sampleswere 141 reading questions which taken by using random sampling technique byusing Statistical Program for Social Science (SPSS) version 20.0. in Look Aheadan English Course for Senior High School Level 1, 2, & 3. The data were analyzedby using Table analysis of cognitive dimension of Revised Bloom Taxonomy. Theanalysis showed that the most dominant cognitive dimension of Revised BloomTaxonomy in remembering dimension (57.45%). The second dominant cognitivedimension is understanding dimension (26.24%). The third dominant cognitivedimension is evaluating dimension (10.64%). The fourth dominant cognitivedimension is creating dimension (3.55%). The fifth dominant cognitive dimension isanalyzing dimension (2.13%). There was no cognitive dimension of applyingdimension that applied in reading question of the textbooks.

Salt And Pepper

Nowadays, during the process of Image acquisition and transmission, image information data can be corrupted by impulse noise. That noise is classified as salt and pepper noise and random impulse noise depending on the noise values. A median filter is widely used digital nonlinear filter  in edge preservation, removing of impulse noise and smoothing of signals. Median filter is the widely used to remove salt and pepper noise than rank order filter, morphological filter, and unsharp masking filter. The median filter replaces a sample with the middle value among all the samples present inside the sample window. A median filter will be of two types depending on the number of samples processed at the same cycle i.e, bit level architecture and word level architecture.. In this paper, Carry Look-ahead Adder median filter method will be introduced to improve the hardware resources used in median filter architecture for 5 window and 9 window for 8 bit and 16 bit median filter architecture.
