TigerJet Network Announces the World's First Single Chip with Built in Flash Drive Controller, Echo Canceller and 16 Bit Audio Codec for Use with USB Speaker Phones.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- TigerJet Network, Inc. today announced the Tiger581, the world's first single chip solution for USB phones with built in flash drive controller, echo cancellation The elimination of an echo in a two-way voice transmission. Echo is created in the telephone company's central office switch when two-wire lines from the customer are converted to four-wire lines for backbone trunks. and a 16 bit audio codec (1) A hardware circuit that converts analog voice into PCM or ADPCM digital code and vice versa. The term may refer to only the A/D and D/A conversion, or it may include the compression technique for further reducing the signal (definition #2 below). See sampling and codec. with speaker phone capability. TigerJet believes that integrating all of the required features into a single chip changes the economic argument so dramatically that VoIP solutions in an office environment will migrate from using dedicated headsets towards the use of business type desktop phones with speaker phone capability. The Tiger581 is the successor to and contains all the functions of the Tiger560 which, until now, has been the most popular choice for implementing a USB Phone solution for VoIP applications. However, because the echo cancellation on the Tiger560 is implemented using PC software, the audio quality depends on many factors including PC performance and network delay. By including hardware echo cancellation on the Tiger581, optimum audio quality is achieved consistently. Another new feature included on the Tiger581 is the flash drive controller which powers an auto-run feature for VoIP applications directly from the flash drive on the phone. This flash drive controller eliminates the need for account setup and installation. Tiger581 was specifically developed to address the mass market business environment with a solution that combines high audio quality and user convenience with optimum cost. Dr. YW Sing, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of TigerJet Network commented, "Using the Tiger581, a desktop USB phone with speaker phone function can be built using a simple manufacturing process and with a BOM (bill of material) of less than $5." Tiger581 is fully software compatible with the Tiger560, and like the Tiger560, it supports keypad scanning, LCD control and ringing buzzer. The 16 bit audio codec and DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive function of the Tiger581 enables on chip echo cancellation and the built in flash controller with auto-run feature enables the automatic account setup and installation of VoIP applications. All primary functions of Tiger581-based VoIP devices are plug and play compatible with WinXP, Vista, Linux and MAC operating systems Operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap. and all popular VOIP applications such as: Skype, MSN (1) (MicroSoft Network) A family of Internet-based services from Microsoft, which includes a search engine, e-mail (Hotmail), instant messaging (Windows Live Messaging) and a general-purpose portal with news, information and shopping (MSN Directory). , GoogleTalk, YahooMessenger, X-ten, SIP, H.323, Delta3,.. are supported. The Tiger581 is currently being sampled to key tier one OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and partners.
