JLS Tour

The second leg of JLS's first headline tour of the UK and Ireland is an arena tour, stopping at major arenas across England, Ireland, Northern Ireland, Scotland and Wales. The tour was announced in November 2009. This tour will start with seven summer shows before heading to the arenas in December 2010. They will also support Westlife when they play Dublin's Croke Park in June 2010. The tour was extended into 2011 due to the demand for tickets for the shows.

Setlist

Lossless JPEG

Lossless JPEG is a 1993 addition to JPEG standard by the Joint Photographic Experts Group to enable lossless compression. However, it might be used as an umbrella term to refer to all lossless compression schemes developed by the Joint Photographic Expert group. They include JPEG 2000 and JPEG-LS.

Lossless JPEG was developed as a late addition to JPEG in 1993, using a completely different technique from the lossy JPEG standard. It uses a predictive scheme based on the three nearest (causal) neighbors (upper, left, and upper-left), and entropy coding is used on the prediction error. The standard Independent JPEG Group libraries cannot encode or decode it, but Ken Murchison of Oceana Matrix Ltd. wrote a patch that extends the IJG library to handle Lossless JPEG. Lossless JPEG has some popularity in medical imaging, and is used in DNG and some digital cameras to compress raw images, but otherwise was never widely adopted.

Lossless mode of operation

Lossless JPEG is actually a mode of operation of JPEG. This mode exists because the discrete cosine transform (DCT) based form cannot guarantee that encoder input would exactly match decoder output. Unlike the lossy mode which is based on the DCT, the lossless coding process employs a simple predictive coding model called differential pulse code modulation (DPCM). This is a model in which predictions of the sample values are estimated from the neighboring samples that are already coded in the image. Most predictors take the average of the samples immediately above and to the left of the target sample. DPCM encodes the differences between the predicted samples instead of encoding each sample independently. The differences from one sample to the next are usually close to zero. A typical DPCM encoder is displayed in Fig.1. The block in the figure acts as a storage of the current sample which will later be a previous sample.

JLS

JLS (an initialism of Jack the Lad Swing) were an English pop/R&B boy band consisting of members Jonathan Benjamin Gill, Marvin Humes, Aston Merrygold and Oritsé Williams, originally formed by Oritsé Williams. They initially signed to Tracklacers production company New Track City and then went on to become runners-up of the fifth series of the ITV reality talent show The X Factor in 2008, coming second to Alexandra Burke. Following their appearance on The X Factor, JLS signed to Epic Records. Their first two singles "Beat Again" and "Everybody in Love" both went to number one on the UK Singles Chart. The band's self-titled debut album was released on 9 November 2009, and has since sold over 1 million copies in the UK. JLS won the awards for British Breakthrough and British Single ("Beat Again") at the 2010 BRIT Awards. They also won several awards at the MOBO Awards for Best song for "Beat Again" in 2009 and also Best Newcomer in the same year. In 2010 they won the MOBO Awards for Best UK act and Best Album. They also went on to win their fifth MOBO in 2012 by winning Best Video for "Do You Feel What I Feel?". They won the title of the UK's hardest-working band for two constitutive years, in 2011 and 2012.
