  • A History of Video Game Consoles Introduction the First Generation
    A History of Video Game Consoles By Terry Amick – Gerald Long – James Schell – Gregory Shehan Introduction Today video games are a multibillion dollar industry. They are in practically all American households. They are a major driving force in electronic innovation and development. Though, you would hardly guess this from their modest beginning. The first video games were played on mainframe computers in the 1950s through the 1960s (Winter, n.d.). Arcade games would be the first glimpse for the general public of video games. Magnavox would produce the first home video game console featuring the popular arcade game Pong for the 1972 Christmas Season, released as Tele-Games Pong (Ellis, n.d.). The First Generation Magnavox Odyssey Rushed into production the original game did not even have a microprocessor. Games were selected by using toggle switches. At first sales were poor because people mistakenly believed you needed a Magnavox TV to play the game (GameSpy, n.d., para. 11). By 1975 annual sales had reached 300,000 units (Gamester81, 2012). Other manufacturers copied Pong and began producing their own game consoles, which promptly got them sued for copyright infringement (Barton, & Loguidice, n.d.). The Second Generation Atari 2600 Atari released the 2600 in 1977. Although not the first, the Atari 2600 popularized the use of a microprocessor and game cartridges in video game consoles. The original device had an 8-bit 1.19MHz 6507 microprocessor (“The Atari”, n.d.), two joy sticks, a paddle controller, and two game cartridges. Combat and Pac Man were included with the console. In 2007 the Atari 2600 was inducted into the National Toy Hall of Fame (“National Toy”, n.d.).

  • Download Media Player Codec Pack Version 4.1 Media Player Codec Pack
    download media player codec pack version 4.1 Media Player Codec Pack. Description: In Microsoft Windows 10 it is not possible to set all file associations using an installer. Microsoft chose to block changes of file associations with the introduction of their Zune players. Third party codecs are also blocked in some instances, preventing some files from playing in the Zune players. A simple workaround for this problem is to switch playback of video and music files to Windows Media Player manually. In start menu click on the "Settings". In the "Windows Settings" window click on "System". On the "System" pane click on "Default apps". On the "Choose default applications" pane click on "Films & TV" under "Video Player". On the "Choose an application" pop up menu click on "Windows Media Player" to set Windows Media Player as the default player for video files. Footnote: The same method can be used to apply file associations for music, by simply clicking on "Groove Music" under "Media Player" instead of changing Video Player in step 4. Media Player Codec Pack Plus. Codec's Explained: A codec is a piece of software on either a device or computer capable of encoding and/or decoding video and/or audio data from files, streams and broadcasts. The word Codec is a portmanteau of ' co mpressor- dec ompressor' Compression types that you will be able to play include: x264 | x265 | h.265 | HEVC | 10bit x265 | 10bit x264 | AVCHD | AVC DivX | XviD | MP4 | MPEG4 | MPEG2 and many more.

  • Lossless Compression of Audio Data
    CHAPTER 12 Lossless Compression of Audio Data ROBERT C. MAHER OVERVIEW Lossless data compression of digital audio signals is useful when it is necessary to minimize the storage space or transmission bandwidth of audio data while still maintaining archival quality. Available techniques for lossless audio compression, or lossless audio packing, generally employ an adaptive waveform predictor with a variable-rate entropy coding of the residual, such as Huffman or Golomb-Rice coding. The amount of data compression can vary considerably from one audio waveform to another, but ratios of less than 3 are typical. Several freeware, shareware, and proprietary commercial lossless audio packing programs are available. 12.1 INTRODUCTION The Internet is increasingly being used as a means to deliver audio content to end-users for en­ tertainment, education, and commerce. It is clearly advantageous to minimize the time required to download an audio data file and the storage capacity required to hold it. Moreover, the expec­ tations of end-users with regard to signal quality, number of audio channels, meta-data such as song lyrics, and similar additional features provide incentives to compress the audio data. 12.1.1 Background In the past decade there have been significant breakthroughs in audio data compression using lossy perceptual coding [1]. These techniques lower the bit rate required to represent the signal by establishing perceptual error criteria, meaning that a model of human hearing perception is Copyright 2003.
