Gast Geplaatst: 14 december 2000 Geplaatst: 14 december 2000 Toshiba Unveils Low-Power, Single-Chip MPEG-4 Decoder<BR> <P>Toshiba America Electronic Components Inc. with its parent company Toshiba Corp. Monday unveiled its production silicon MPEG-4 decoder which conforms to the latest MPEG-4 industry standard. <P>The device, designated the TC35274XB, integrates an MPEG-4 decoder with 4-megabits (Mb) of embedded DRAM to deliver a single-chip, low-power solution. The new MPEG-4 decoder will enable designers to create advanced wireless communication products that can receive and decode streaming media. <P>Toshiba's embedded DRAM technology enables a considerable reduction in power dissipation due to the lower capacitance on-chip connections, without any degradation in the chip's performance. By incorporating 4Mb of embedded DRAM, Toshiba has reduced power dissipation of the device to 50-milliwatts (mW), lower than similar solutions using off-chip memory. <P>From the application perspective, this could provide a battery-powered mobile videophone incorporating Toshiba's MPEG-4 chip with more than double the battery life of the same phone using an off-chip memory solution. <P>"Toshiba is a world leader in the development of MPEG technology and today we reinforced our leadership by delivering the industry's first low-power, single-chip MPEG-4 decoder," said Andrew Burt, director, TAEC wireless market development. <P>"This new device is poised to revolutionize the mobile products marketplace by enabling the next generation of multimedia-equipped wireless devices such as cellular phones, PDAs, and real-time remote security/surveillance solutions." <P>The TC35274XB performs 15 frames per second of MPEG-4 video decoding with QCIF (176 x 144 pixels) at 30-megahertz (MHz) clock frequency. The video core consists of a 16-bit RISC processor and dedicated hardware accelerators that allow programmability while delivering high performance and low-power dissipation. <P>The firmware program for the RISC processor is downloaded into the embedded DRAM before beginning any operation. Additional applications, such as H.263, are performed by using the appropriate firmware. <P>IMT-2000 handsets and mobile terminals will support transmission of higher-quality motion pictures and improved sound quality. MPEG-4's video compression technology is specifically designed for wireless video transmission and is expected to become a key element of IMT-2000 services. <P>Sample pricing for the TC35274XB MPEG-4 decoder is $35. Samples will be released in first quarter of 2001, with mass production slated for second quarter of 2001. <P><BR>
Gast Geplaatst: 14 december 2000 Geplaatst: 14 december 2000 Mpeg-4 bestaat al een hele tijd en de drivers bestaan al redelijk lang op PC (ontwikkeld door Microsoft). Wie kent de 'gepatchte' versies niet zoals Divx;-) en AngelPotion? Met deze kun je ook zelf de mpeg-4 norm toepassen op je eigen mpeg-2's.<BR>Een volledige film 640*480 resolutie op 1 gewoon 650Meg cd'tje... No prob.<BR>Als ze ooit op satelliet zo gaan uitzenden kunnen de meeste transponders op pensioen wegens niet gebruikt;-)))<P>Dankzij die chip kunnen we beginnen te hopen op een DivX/Mpeg 4 speler! Woehoe!<P>Grtz,<BR>Wimpie.
