Recently, multimedia and communication technology company ImaginaTIon Technologies announced that the company will launch the first members of its PowerVR Series4 video core.

The PowerVR Series4 D4500MP video decoder and E4500MP video encoder are based on the highly successful PowerVR VXD and VXE Series3 multi-standard video codec technology. These multi-channel architecture video silicon semiconductor intellectual property (IP) provides enhanced features designed for modern applications, such as unprecedented color accuracy for wireless display and video capture, and high-definition (HD) and ultra-high-definition (Ultra-HD) displays (H.264 L5.2 4Kx2K @ 60fps).

While having industry-leading performance, these video processing cores still maintain a small area and ultra-low power consumption, making them ideal for consumer electronics applications. These cores have full scalability from single channel to four channels, ensuring 1080P performance and low power consumption requirements in a compact area, or achieving industry-leading 4Kx2K performance.

"With the ability to process more than one billion colors in full resolution, the enhanced color processing capabilities of the PowerVR D4500MP and E4500MP ensure that significant performance improvements are brought to today's demanding video applications, and that crisper and more precise video content can be applied to applications such as Contemporary applications such as wireless display and high-quality video capture. ”Tony King Smith, ImaginaTIon ’s vice president of marketing, said:“ As the supply of OLED displays and 10-bit displays that offer a wider color gamut grows, consumers demand more experience than ever. Higher color fidelity. In addition, with "ultra real-time" HD video processing performance, these cores can be perfectly applied to the most extensive display applications today, and can also be used for such as large wall display and huge splicing screen Wait for future Ultra-HD (Ultra-HD) 4Kx2K applications to provide more than enough performance guarantees. "

Full-resolution realistic color processing, supporting more than one billion colors

The PowerVR D4500MP and E4500MP support enhanced color depth, provide up to 10-bit color accuracy, and can present more than one billion colors, while the current traditional 8-bit system can only provide 16 million colors. The increase in color depth support allows the SoC to maintain high-precision internal processing throughout the entire process from video source to display output, thereby achieving true and realistic color reproduction. Enhanced color performance can provide the required color fidelity for the latest generation of 10-bit and OLED displays to ensure maximum performance. The use of 10 bits can also help to significantly reduce the color banding phenomenon in traditional 8-bit systems.

To further enhance the available color rendering capabilities, the video processor core has increased the color resolution to 4: 4: 4 (or 4: 2: 2) to provide full resolution data for all video unit components. This makes the conversion between YCbCr and RGB easier and more accurate because it does not require interpolation, making it perfect for wireless display subsystems. Repeated conversion between traditional color formats (and resolutions) can lead to loss of detail and blur due to interpolation errors, and the use of 4: 4: 4 guarantees the elimination of such errors.

The enhanced resolution and fidelity performance of this series of cores enables application products such as video cameras, digital cameras, SLR cameras, and mobile phones to maximize the performance of image sensors that usually provide at least 10-bit color depth, which enables them to provide unprecedented Professional-grade image quality, which provides manufacturers with product differentiation and brings added value to consumers.

Encoding and decoding performance for future applications

PowerVR D4500MP and E4500MP respectively improve the decoding and encoding performance of Full HD 1080P video applications, ensuring realistic ultra high-definition quality, multi-stream HD channel browsing, high frame rate of high-speed continuous fine slow motion for sports events and other special content stand by. These new cores can also provide industry-leading performance for ultra-high-definition 4Kx2K video, and this is the core technology of future video applications, which can provide four times the visual information capacity of traditional high-definition TVs and "information wall" flat display Application, which can closely integrate TV with application, social media and channel browsing.

The inner part of the IP core

PowerVR D4500MP supports all mainstream video standards, including H.264 HP, H.264 MP, H.264 BP, H.264 MVC, VC-1, VP8 / WebM, H.263, RMVB (Real Video), MPEG- 2. MPEG-4, AVS, VP6 and JPEG.

The PowerVR video core remains the industry record holder in terms of low power consumption. It can decode H.264HP 1080P30 video with a power consumption of less than 15 milliwatts (40LP process).

The PowerVR D4500MP multi-standard, multi-stream video decoder IP core uses a multi-core architecture to enable its performance to be conveniently targeted at high resolution or high frame rate applications with ultra-low power consumption when using mainstream silicon semiconductor processes It needs to be configured until the maximum H.264 level 5.2 level is supported. This unprecedented performance can ensure that 4K resolution content is decoded and output at H.264 L5.2 4Kx2K @ 60fps.

By allowing streams of any format up to H.264 HP to be decoded at ultra-real-time speeds, the PowerVR D4500MP ensures the support of a growing number of excellent applications that can greatly enhance the user experience, including 1920x1080 @ 120fps high-speed photography slow-motion playback decoding, Stunt play mode and video editing application.

PowerVR E4500MP is a multi-standard, multi-stream video encoder that supports all mainstream high-definition video and still image standards. In addition, E4500MP also supports up to 4Kx2K @ 30fps resolution encoding. The video source scaling component of E4500MP can reduce the size of the video source code stream, which is an important application feature of various new applications such as adaptive streaming media, simulcast low resolution and high resolution video. The E4500MP core also supports H.264 lossless mode, which is a basic requirement for applications such as the highest fidelity video transmission.

These cores are now available for licensing and will be given priority to leading partners in the second half of 2012.

Drum type Rice Cooker

 

Features

This type rice cooker is famous with drum type appearance, which is easy operation and easy clean.

There are two type of inner pot ,  one type called white pot which is without non-stick but cheaper price .another one called non-stick pot is polished with emery, Also there are two type non-stick with different price ,it`s depending on different demands to use.

 

And the inner pot cannot be burned on the stove, which will make the pot transfigured and bad contact with the heating plate. While cooking , the heating plate or the fuse is most likely to be burned for the bad contact of the inner pot and the heating plate, Besides, make sure to dry the pot before putting into the outer shell of the rice cooker ,or else the drops of water flowing on the heating plate, will make the heating plate rusted.

 

Applications

Many peoples are used drum type rice cooker for congee and soup, some of peoples are prefer to use this type rice cooker for steaming.
