Pedigo contributed this article to Tom's Guide's Expert Voices: Op-Ed & Insights. When most people think of the latest and greatest in home theater, they recall articles, photos and conversations about the newest screen or projector — the visual display. However, there is another component to home theaters that is the true all-star when it comes to creating a cinema-like experience in our homes: Surround-sound systems are what enable home theaters to deliver a truly transformative experience. Soon enough, when we think of the latest and greatest in home theater, we'll all be talking about the leaps and bounds being made in the newest audio formats, the immersive audio. The cinematic experience has long been dominated by surround sound. Classics like "Star Wars: Episode IV" and "Jurassic Park" were among the first modern movies to use this sound format, which has since progressed from using two speakers to five speakers to seven speakers — or more. Regardless of the number of speakers, until recently the audio still simply surrounded you on a horizontal plane. It's only when you have an immersive, multilayered audio experience that you realize how much deeper into a scene an audio system can take you. With movies like "Mockingjay: Part 2," "Sicario" and "Star Wars: The Force Awakens," we're becoming genuinely immersed in the action of these films through a new approach to audio. MORE: Our Favorite Soundbars for Small and Big TVs Immersive audio is allowing sound engineers to get creative with speaker placements by adding elevated and/or overhead speakers to the traditional horizontal plane format used with traditional 5.1 or 7.1 surround-sound systems. Imagine using additional speakers to create a 3D space where you're hearing sounds from not only around you, but above you. Multichannel audio companies like Dolby Labs, DTS and Auro Technologies are working to make this experience achievable with Dolby Atmos, DTS Neo:X and Auro-3D, respectively. Immersive audio also steps outside the boundaries of a channel-based audio system and challenges sound engineers to use an object-based approach, moving away from the traditional trend of pairing sounds with specific speakers on a horizontal plane. Now, engineers associate sounds with individual objects in a 3D space, such as bullets whizzing by or tires peeling out during a high-speed chase. The information associated with these individual sounds (objects) are deciphered in your AV system and distributed through a combination of speakers to reproduce that sound in your home. As with when surround sound became popular, the only way to enjoy this advanced immersive audio system is to find content that is encoded with the technology. This does ultimately mean replacing your DVD/Blu-ray collection, but at a slow, affordable pace, considering content is slowly transitioning to being remastered for this system. Studios are releasing Blu-rays and other content in this format, so it is important to keep a pulse on the immersive audio trend and find the appropriate films that will cater to your new audio system. As immersive audio technology makes its way into homes, it is also important to ensure consumers are informed and educated on how best to implement it — some products will need to be purchased, while others are already a part of your current system. As you search for sources, it is crucial to identify the correct technology professional so you're not oversold on products or services and so you have the new technology integrated into your home effectively, both from a cost and functionality standpoint. It is no doubt that it is an exciting time for the home theater enthusiast as the landscape in this industry continues to grow in such innovative and experiential ways. Content, such as films and concerts, will continue to be recorded or remastered in immersive formats like DTS Neo:X, Dolby Atmos and Auro-3D. In my next article, I will take you on a tour of these three formats that are bringing the immersive audio experience to life and tell you a bit more about what the future holds.

LG Electronics fired an opening salvo with a new OLED television no thicker than four stacked credit cards. The South Korean consumer electronics colossus opened a packed day of press conferences at the annual tech extravaganza in Las Vegas with a line-up that included an OLED Signature panel touted as "quite literally, a picture on glass." The television measures an unprecedented 2.57 mm, LG Electronics USA marketing vice president David VanderWaal said during an on-stage presentation. "Our passion and commitment for OLED has never been stronger," VanderWaal said. "OLED TV is already recognized as the best TV ever." OLED displays have pixels that emit their own light, while pixels in LCD TVs are illuminated by backlights. OLED screens boast deeper blacks, allowing for a wider range of color than LCD displays. They also tend to come with higher price tags. LCD televisions remain "the king of screens" with sizes trending up, according to the Consumer Technology Association, the trade group behind CES. One in every five televisions sold this year is expected to be 50 inches or more, measured diagonally, and feature ultra high-definition 4K resolution. LG was among the TV makers here introducing new models that will come with a freshly minted Ultra-High Definition Premium Certification signalling that they meet standards freshly established by an alliance representing manufacturers, technology companies and studios creating content. "The criteria established by this broad cross-section of the Ultra HD ecosystem enables the delivery of a revolutionary in-home experience," UHD Alliance chairman Hanno Basse said in a release. "And, the Ultra HD Premium logo gives consumers a single, identifying mark to seek out so they can purchase with confidence." Analysts told AFP they expected adoption of 4K ultra-high definition televisions to pick up speed this year as prices get in reach of more consumers and the displays become marketplace norms. LG built Dolby Vision technology into its new televisions. "Dolby Vision creates a picture so lifelike you will forget you are looking at a TV screen," Dolby Labs senior vice president Giles Baker said during the presentation. Dolby Vision has been used in major films including box-office record-breaker "Star Wars: The Force Awakens," according to Giles. The LG television line-up included "Super UHD" LCD displays as slim as 6.6 mm and a new flagship 8K television measuring 98 inches diagonally. Later in the day, leading television maker Samsung unveiled a new line of ultra-high-definition LCD televisions capable of not only streaming games or shows from the Internet but able to serve as command centers for smart home devices, from locks and lights to thermostats and appliances. Samsung Electronics visual display business president Hyun Suk Kim pulled back the curtain on new SUHD Quantum Dot televisions that he said marked the "start of a new era of TV." "This year we are focused on bringing the television experience into the future," Samsung Electronics America executive Dave Das said. "The new SUHD TV is a giant leap forward in time." New models have software designed to better consolidate traditional and online content, and remote controls that automatically detect and command accessories with no set-up needed. Samsung's new SUHD televisions will also allow people to play more than 500 video games, including blockbusters such as "Assassin's Creed" streamed online in partnership with Sony's PlayStation Now service, without needing consoles. The TVs will also act as command centers in smart homes by incorporating technology from Silicon Valley start-up SmartThings, which Samsung bought in 2014, allowing them to control devices synched to the platform. "I think this is really a big step forward for opening up the market," SmartThings founder and chief Alexander Hawkinson told AFP. "You can have a smart home basically for free as a starting point; it is pretty amazing." SmartThings is based on open standards, letting tens of thousands of developers tailor applications to work with the platform. "In 2016, we're going beyond anything we've done before to offer a remarkable synergy of design, engineering and craftsmanship," said Hyun Suk Kim. Sony unveiled a new flagship LCD televisions and boasted that it is ramping the quality of displays with "high dynamic range" technology that appeared to be a rage at CES. The Japanese consumer electronics and entertainment colossus said it has also broadened its line of ultra-slim Bravia televisions. Sony also introduced an Ultra 4K streaming service that taps into the company's film and television library and is optimized for Bravia models.

ABSTRACT Peer-to-peer (P2P) media streaming systems have recently become a major type of application traffic. In these applications, an important issue has been the block scheduling problem, which determines how each peer exchanges the data blocks from others. Scalable streaming in P2P networks has recently been proposed to address the heterogeneity of the network environment. In this paper, we first define a priority function for each block according to the block's significance for video content. The block scheduling problem is then transformed to an optimization problem that maximizes the priority sum of the delivered video blocks. The simulation results show that the proposed algorithm offers excellent performance for P2P streaming service. © 2013 IEEE.

There are well-known observations of movie content being displayed at different frame rates. Although the terms are not consistent across the industry, four main degradations are observed of the signal as compared to nonsampled motion (i.e., real-world motion): (1) nonsmooth motion, (2) false multiple edges, (3) flickering, and (4) motion blur. In natural imagery, all four of these effects are generally visible at typical movie frame rates. The spatiotemporal window of visibility has proved successful in describing when motion looks distorted from the realworld smooth motion. However, that model predicts only detection performance and does not address the appearance or magnitude of motion distortions. In addition, well-known image capture and display parameters are also involved with frame rate questions, such as exposure duty cycle (angle), object speed, and object contrast. There are also known interactions with brightness and contrast, which are also generally linked in the end-to-end system. For example, the Ferry-Porter law1 of psychophysics indicates the temporal frequency bandwidth of vision increases with increasing adapting luminance. We aimed to isolate the nonsmooth motion component of judder in a psychophysical study by using fundamental test signals, such as the Gabor signal. Two-interval forced choice methodology was used to generate interval scales of the magnitude of judder, or judderness. Results are presented for the viewer assessment of the magnitude of judder/judderness as a function of these key parameters tested in isolation. Copyright © 2015 by the SMPTE.

Working on making Buffer an inclusive place where all kinds of people feel they belong and thrive is one of my favorite things. It’s a unique time to be working on diversity goals at a tech startup. On the one hand, there is quite a bit of work to do to make the strides we’d all like to make. On the other hand, there is so much hope and so many cool innovations, programs, and even tools that can help move us toward where we want to be. We’ve shared a lot of our thoughts, strategies and mistakes so far. As I begin to embark on making diversity a bigger part of my job (Potential future title: Belonging Booster. What do you think?) I wanted to check out what some other tech companies are working on when it comes to inclusivity. My research journey took me all the way from the NFL to the symphony orchestra as I discovered tech companies are pulling inspiration from many different areas. Here are seven cool inclusivity tactics that my investigation turned up. Who’s using it: Facebook and Pinterest What does tech have in common with the National Football League? At least one element: the Rooney Rule. Introduced by the NFL in 2003, the Rooney Rule (named for Pittsburgh Steelers owner Dan Rooney, who headed the league’s diversity committee) is simple. It requires teams to interview at least one minority candidate for every head-coaching and general manager vacancy. This change quickly increased the NFL’s number of minority hires from 6% to 22%. Companies like Facebook and Pinterest have adopted their own versions of the Rooney Rule, often translating it to the idea that at least one woman and one underrepresented minority be considered for every open position (sometimes, every open senior position). Who’s using it: Twitter and Pinterest 17% of all Americans are Latino, 13% of all Americans are black, 6% of all Americans are Asian, and 62% of Americans are white. 50% of Americans identify as male, and the other 50% as female. Tech companies’ numbers generally don’t reflect these percentages very closely. Pinterest acknowledged this after releasing these demographic numbers: So Pinterest did something pretty unique and transparent to address this. From its blog post: Following suit was Twitter; here are its goals for 2016: Transparently sharing specific inclusion goals feels like a great method to create accountability and honesty around how things are going. According to Fortune, LinkedIn is among the most gender-diverse of high-profile technology companies—at the end of 2014, almost half of LinkedIn’s employees were non-white. How did it get there? One clue might be in this interview with Erica Lockheimer, LinkedIn’s director of engineering growth and women in tech. Erica explains that 20% of her time—and therefore a portion of her salary and bonus—is tied to LinkedIn’s overall diversity goals. Several others in management have a similar arrangement, and at least another 50 employees have dedicated 5% of their time—and a portion of their overall annual pay—toward working on diversity at LinkedIn through things like unconscious bias training and "acts of inclusion." 20% time is a cool strategy because it takes the mission outside the realm of just a select few at an organization and makes it something everyone can work toward, together. Here’s a cool strategy from Google: the search giant is embedding engineers at historically black colleges and universities, where they teach, mentor, and advise. Google has software engineers in residence at Howard University in Washington, D.C., Hampton University in Hampton, Virginia, Fisk University in Nashville, and Spelman and Morehouse Colleges in Atlanta. Googlers teach courses and also train students on skills like how to send a professional email and how to master a technical engineering job interview. Recently, Slack added a new way for developers to connect to the app, via the "Add to Slack" button. Quite a few users noticed that the hand in the illustration wasn’t the "usual" look for design: The seemingly small detail of skin color in the launch graphics resonated with many users. Diogenes Brito, the designer on the project, wrote about the decision beautifully: Seeing yourself recognized and included in design is a powerful feeling, and Slack recognizes this in multiple ways: For a small start in this direction, check out this great connection of stock photos of tech women of color. (You might recognize the top image in this post!) Who’s using it: Facebook, Google, and others Our brains aren’t so great at making rational decisions. There are literally hundreds of cognitive biases that trick us every day. Here are just a few: How can we retrain our flawed brains? Some say a start is to be aware of our biases. Companies like Google and Facebook are working hard on unconscious bias training for its teams, and sharing some great resources with all of us. (Seriously, both those links are gold!) Speaking of unconscious bias, here’s how orchestras in the United States uncovered and worked through one of their own biases. As late as 1970, the top five orchestras in the U.S. had fewer than 5% women. By 1997, that number was up to 30%! What changed? Orchestras began using , where performers stayed behind a screen as they played, unseen by the judges. (Kinda like TV’s The Voice). According to a 2001 study, blind orchestra auditions the probability that a woman would advance from preliminary rounds by 50%. Could blind auditions work for tech, too? The startup Gap Jumpers makes software that creates a blind audition conducted via computer. Companies like Dolby Labs and Mozilla have already signed on to try this unique method. We’re excited to explore many of these strategies at Buffer soon, and will share with you how it goes. How are you working on bringing more diverse perspectives to your team, or to make your workplace more inclusive for all? I’d love to hear what strategies you’re thinking of or working on, and any thoughts you might have for Buffer as we work on building a more diverse team.

With the recent rapid growth of communication, networking, and video compression technology, the real-time video streaming applications have evolved from traditional single-stream along simple transmitter-to-receiver path to complex multiple streams through advanced full-fledged cooperative networks. In this chapter, three major emerging advanced concepts are introduced: cooperative transmission, distributed source coding (DSC), and share auction based resource allocation. Cooperative transmission has been demonstrated as an effective transmission scheme to form virtual multiple-input and multiple-output (MIMO) system and provide diversity gains. Distributed source coding brings a new coding paradigm by letting the receiver jointly exploit the statistical dependencies among multiple streams sent from different sources without coding rate penalty. Share auction brings efficient way to allocate system resources in a distributed and collaborated manner to alleviate computation complexity. Based on these advanced concepts along with the advanced video processing ability for side information generation, a wireless multi-stream video transmission framework over full-fledged cooperative networks is presented. © 2011 Springer-Verlag Berlin Heidelberg.

Display technology has been improving rapidly, in some areas faster than others. Televisions, tablets, and smart phones bring images to life through a combination of a brighter maximum luminance, a deeper black level, and/or a wider color gamut. Preference studies in this area also confirm that viewers are looking for these increased capabilities in their displays. One such study performed on a TV-sized display at Dolby Laboratories  found that to satisfy 90% of viewers a luminance dynamic range of 0.005 to 20,000 cd/m2 would be required. Translating results from small displays to the larger screens of the cinema is not always straightforward because of the conjecture that large screens will influence a viewer's preferences differently. For example, it is assumed that, in comparison to a smaller display (i.e. television), the brightness preference for the cinema is dimmer. This generalized assumption, however, includes multiple aspects such as contrast increased flickering with higher luminance, and different fields of view. To investigate those aspects, we have conducted a study on viewer preferences for the cinema environment isolating the maximum diffuse luminance, the minimum luminance, and highlight luminance from these other factors. We used a 6 kW cinema projector and 13 foot, 2.8-gain screen, producing a luminance dynamic range of 0.002 to 2100 cd/m2, and concluded that the most demanding viewers prefer 22 stops of cinema dynamic range - double the number of stops of the existing dynamic range of the cinema.

How does one become 'the best'? You run faster; jump further; eat the most hot dogs. In these examples the winner is objective. They are the Usain Bolts, the Joey Chestnuts. But how do you define 'the best' when dealing with subjective matter? Milk chocolate or dark chocolate? Rec.2020 and 1,000 cd/m2 or P3 with 4,000? In terms of image quality, both consumers and creators want to know what makes 'the best'. Consumers want a number or a letter grade, and creators and engineers want to know how to make that image or television rate the highest. It comes down to creating a metric that factors in all image attributes and weighting them by how each are valued by consumers. We will discuss the challenges faced in creating such a metric, and our study that compared image quality dimensions such as dynamic range, color primaries, bit depth, and contrast. © 2015 Society of Motion Picture & Television Engineers® (SMPTE®).
