W880i
The Sony Ericsson W880i is a mobile phone that was announced on 6 February 2007 and released in spring 2007. Part of Sony Ericsson's Walkman series, the phone has been popular due to its tiny dimensions and low weight. At only 9.4 mm thick, the W880 was one of the few phones on the market that were thinner than 1 cm (10 mm), the other notable example being the Nokia 5310 XpressMusic from later that year. The W880i is available in three different colour schemes; "Flame Black", "Steel Silver" and "Pitch Black". There is a fourth color scheme, "Gold", which is exclusively available to Vodafone. There is also a non-3G version of the phone; the Sony Ericsson W888c. Features The W880 features a 2.0-megapixel camera (without autofocus and flash) and a secondary VGA camera located on the front which can be used for 3G video conferencing. The phone also comes with Walkman Player v2.0, which gives a faster interface with very few differences from the previous version. T ...

Sony Ericsson W810
The W810 (also available as the W810i and W810c) is a camera phone produced by Sony Ericsson. It was released in January 2006. It is the successor of the W800. Features The W810 is part of Sony Ericsson's Walkman line of mobile phones. While being similar to the W800, the W810 benefited from several improvements. Most notably are quad band connectivity, EDGE support for faster wireless data transfers, a light level sensor, a slightly enhanced display, but slightly reduced battery life. Other features include a full function internet browser, two megapixel digital camera with auto-focus and flash, the HPM-70 stereo headset, Memory Stick PRO Duo slot, 20 MB of internal memory, and a music-only mode where phone functions are fully turned off, which also allows the phone to be used as a Walkman in areas mobile phones would usually be barred from, such as airplanes and hospitals, in addition to providing longer battery-life. The phone supported MP3, AMR, MIDI, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

W850i
The Sony Ericsson W850i is the first 3G sliding form factor mobile phone by Sony Ericsson, introduced in Q2 2006. It is a member of their Walkman line. The phone made its first public appearance in the 2006 movie '' The Da Vinci Code'', months before its release. It is similar mechanically to the Sony Ericsson K800i, but differs in its form factor, memory card support of the Memory Stick PRO Duo instead of Memory Stick Micro, and the camera (2.0 megapixels instead of 3.2 for the K800i, and with some additional features removed) The phone is available in Precious Black or Golden White and is configured for operator over the air (OTA) music download services and accepts popular music file formats including e-AAC+, and includes a 1 GB Memory Stick PRO Duo. The Golden White version has a gold Walkman logo on the back which the black version does not include. The Walkman player contains Gracenote Mobile TrackID, which enables a user to record a few seconds of a song, either v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.

Memory Stick Micro
The Memory Stick is a removable flash memory card format, originally launched by Sony in late 1998. In addition to the original Memory Stick, this family includes the Memory Stick PRO, a revision that allows greater maximum storage capacity and faster file transfer speeds; Memory Stick Duo, a small-form-factor version of the Memory Stick (including the PRO Duo); the even smaller Memory Stick Micro (M2), and the Memory Stick PRO-HG, a high speed variant of the PRO to be used in high-definition video and still cameras. As a proprietary format, Sony exclusively used Memory Stick on its products in the 2000s such as Cyber-shot digital cameras, Handycam digital camcorders, WEGA and Bravia TV sets, VAIO PCs, digital audio players, and the PlayStation Portable game console, with the format being licensed to a few other companies early in its lifetime. With the increasing popularity of Secure Digital around 2010, Sony started to include SD in their devices which was seen as a Sony los ...

Windows Media Audio
Windows Media Audio (WMA) is a series of audio codecs and their corresponding audio coding formats developed by Microsoft. It is a proprietary technology that forms part of the Windows Media framework. WMA consists of four distinct codecs. The original WMA codec, known simply as ''WMA'', was conceived as a competitor to the popular MP3 and RealAudio codecs. ''WMA Pro'', a newer and more advanced codec, supports multichannel and high resolution audio. A lossless codec, ''WMA Lossless'', compresses audio data without loss of audio fidelity (the regular WMA format is lossy). ''WMA Voice'', targeted at voice content, applies compression using a range of low bit rates. Microsoft has also developed a digital container format called Advanced Systems Format to store audio encoded by WMA. Development history The first WMA codec was based on earlier work by Henrique Malvar and his team which was transferred to the Windows Media team at Microsoft. Malvar was a senior researcher and manager ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adaptive Multi-rate Compression
The Adaptive Multi-Rate (AMR, AMR-NB or GSM-AMR) audio codec is an audio compression format optimized for speech coding. AMR speech codec consists of a multi-rate narrowband speech codec that encodes narrowband (200–3400 Hz) signals at variable bit rates ranging from 4.75 to 12.2 kbit/s with toll quality speech starting at 7.4 kbit/s. AMR was adopted as the standard speech codec by 3GPP in October 1999 and is now widely used in GSM and UMTS. It uses link adaptation to select from one of eight different bit rates based on link conditions. AMR is also a file format for storing spoken audio using the AMR codec. Many modern mobile telephone handsets can store short audio recordings in the AMR format, and both free and proprietary programs exist (see Software support) to convert between this and other formats, although AMR is a speech format and is unlikely to give ideal results for other audio. The common filename extension is .amr. There also exists another stora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MPEG-4 Part 14
MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. The only filename extension for MPEG-4 Part 14 files as defined by the specification is .mp4. MPEG-4 Part 14 (formally ISO/IEC 14496-14:2003) is a standard specified as a part of MPEG-4. Portable media players are sometimes advertised as "MP4 players", although some are simply MP3 players that also play AMV video or some other video format, and do not necessarily play the MPEG-4 Part 14 format. History MPEG-4 Part 14 is an instance of the more general ISO/IEC 14496-12:2004 (MPEG-4 Part 12: ISO base media file format) which is directly based upon the QuickTime File Format which was published in 2001. MPEG-4 Part 14 is essentially identical to the QuickTime File Format, but formally specifies support for Initial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AAC+
High-Efficiency Advanced Audio Coding (HE-AAC) is an audio coding format for lossy data compression of digital audio defined as an MPEG-4 Audio profile in ISO/IEC 14496–3. It is an extension of Low Complexity AAC (AAC-LC) optimized for low-bitrate applications such as streaming audio. The usage profile HE-AAC v1 uses spectral band replication (SBR) to enhance the modified discrete cosine transform (MDCT) compression efficiency in the frequency domain. The usage profile HE-AAC v2 couples SBR with Parametric Stereo (PS) to further enhance the compression efficiency of stereo signals. HE-AAC is used in digital radio standards like HD Radio, DAB+ and Digital Radio Mondiale. History The progenitor of HE-AAC was developed by Coding Technologies by combining MPEG-2 AAC-LC with a proprietary mechanism for spectral band replication (SBR), to be used by XM Radio for their satellite radio service. Subsequently, Coding Technologies submitted their SBR mechanism to MPEG as a basis of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Audio Coding
Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 encoders at the same bit rate. AAC has been standardized by ISO and IEC as part of the MPEG-2 and MPEG-4 specifications.ISO (2006ISO/IEC 13818-7:2006 - Information technology -- Generic coding of moving pictures and associated audio information -- Part 7: Advanced Audio Coding (AAC), Retrieved on 2009-08-06ISO (2006, Retrieved on 2009-08-06 Part of AAC, HE-AAC ("AAC+"), is part of MPEG-4 Audio and is adopted into digital radio standards DAB+ and Digital Radio Mondiale, and mobile television standards DVB-H and ATSC-M/H. AAC supports inclusion of 48 full-bandwidth (up to 96 kHz) audio channels in one stream plus 16 low frequency effects ( LFE, limited to 120 Hz) channels, up to 16 "coupling" or dialog channels, and up to 16 data streams.
