ON CONTROL AND CONNECTIVITY
AirPlay and iControlAV2 App Enhance the Home Theater Experience for iPad, iPhone & iPod touch
“By expanding on networked features such as AirPlay and DLNA, and combining them with exclusive control functions such as iControlAV2 and Air Jam, Pioneer’s new line of Elite receivers is making it easy for consumers to integrate their portable devices while still providing them with superior audio and video performance they expect from our brand,” said Chris Walker, director AV marketing and product planning for the home entertainment division of Pioneer Electronics (USA) Inc.
The Power of Connectivity
AirPlay – Elite consumers have complete access, control and playback of their entire iTunes music library wirelessly through their home theater system. The AS-WL300, optional wireless LAN converter from Pioneer (sold separately), is available to simplify the connection process. Users can quickly and easily enjoy all their music with song information and album art simultaneously displayed on a connected monitor/TV. AirPlay requires iTunes 10.1 or later and iPad, iPhone or iPod touch with iOS 4.2.
Air Jam – Encouraging social connectivity via entertainment devices, Pioneer’s free Air Jam App is available from the App store for iPad, iPhone and iPod touch or at chúng tôi Compatible with four of the five Elite receivers, the app allows pairing of up to four devices via Bluetooth (optional AS-BT200 Bluetooth adapter required). Once linked, each individual can cue songs from their own music libraries to create a shared playlist to play back on the AV Receiver. Each connected device also displays the list of songs added by all the users and which device a song plays from. The Air Jam App conveniently stores the lists of songs created for each session for future purchases at the iTunes Store.
DLNA Certified (1.5) – The new line of Elite receivers are also DLNA Certified (1.5), allowing music content to be shared from a PC to the receiver via the consumers’ home network. Through Ethernet or the optional AS-WL300 wireless LAN converter (sold separately), each receiver can access and play high resolution music (up to 192kHz/24-Bit). Audio can also be streamed and controlled through the Elite receivers using a device that supports UPnP / DLNA media servers and renderers, enabling an entirely new way for consumers to share and play their music collection.
Bluetooth Audio Streaming – With the optional Bluetooth adapter, the entire lineup of receivers features wireless Bluetooth transfer of audio content from any A2DP Bluetooth wireless enabled mobile device or personal computer. Pioneer’s AS-BT200 ($99) Bluetooth adapter allows listeners to keep their phone close to them while they enjoy music through their home theater system. And, with Pioneer’s exclusive Sound Retriever AIR technology, specifically designed to enhance Bluetooth audio transmissions, music playback delivered through Bluetooth is near-CD sound quality.
vTuner – The line also brings thousands of high quality Internet radio stations into the living room with vTuner for endless music entertainment. The feature is further enhanced on the VSX-52 and VSX-53 with the addition of other Internet radio based music services such as PANDORA.
Growing Mobility
Portable devices such as the iPad, iPhone and iPod touch are becoming exciting and ever-expanding components of home entertainment systems. Pioneer’s Elite receivers are designed to utilize the wealth of content from these types of devices as well as provide a larger emotional experience of high definition multi-channel home theater.
Each receiver in the lineup is “Made for iPad, iPhone and iPod” and comes with a free USB/video cable to provide an “out of the box plug-and-play” convenience. Consumers can enjoy audio, video and photos stored on their mobile device with no “optional dock required,” in addition to charging while plugged into the receivers.
iControlAV2 – Pioneer is placing even more home entertainment control in the hands of enthusiasts with its iControlAV2 App enabling an iPad, iPhone or iPod touch to control four out of the five Elite receivers. Available free from the App store for the iPad, iPhone and iPod touch or chúng tôi the iControlAV2 App controls volume, bass, balance and room settings as well as the ability for the user to choose Internet radio stations and music files from network-attached storage (NAS) on a home network. For iPad users, the iControlAV2 integrates all four app controls into an intuitive single screen. The app also includes control for Pioneer Blu-ray Disc players. Additional features include sound adjustments that enable users to create their own equalizer settings by simply drawing their desired equalizer curve on the screen and for iPad consumers, detailed graphic representations of before and after Pioneer’s MCACC room calibration feature.
Maximize Television Performance
Marvell Qdeo video processors – The top Elite models, the VSX-52 and VSX-53, offer high quality video processing for maximum performance and flexibility powered by Marvell’s award-winning Qdeo technology. Marvell Qdeo offers a truly immersive viewing experience by capturing, processing and rendering a wider variety of video signals ranging from high definition Blu-ray Disc to portable video sources such as smartphones.
Advanced Video Adjust – Available on the VSX-50 and up, Pioneer’s new Advanced Video Adjust technology automatically optimizes video signals by the type of display (selected manually) connected to the receivers, such as Plasma, LCD and Front Projector. For example, the receivers can reproduce a detailed and virtually noiseless image on Plasma panels, enhance the black level of LCD displays, and produce sharper, more vivid image matching for front projectors. The receivers can further adjust and enhance images based on the user’s viewing distance from their display by utilizing the distance information established during MCACC (Multi-Channel Acoustic Calibration System) calibration to determine how much adjustment is necessary.
Stream Smoother – Pioneer is among the first to create its own technology to enhance compressed video files with Stream Smoother, available on the VSX-52 and VSX-53 models. The feature automatically calibrates images coming from the Internet via other devices such as Blu-ray Disc players reducing compression noise and establishing more detailed, finer images. The technology is especially helpful with low bit-rate video sources originally intended for viewing on small screens.
AVNavigator (Interactive Assistance)
Wiring Navi – Pioneer is making the installation process for each receiver simple by providing consumers an interactive guide application with the use of a Window-based PC. Users simply answer a series of questions about the hardware connected to the system and the application will automatically update the receiver with the correct settings.
The new line of Elite AV receiver models will be available in the summer of 2011.

There’S More To Airplay 2’S 3Rd
There’s more to AirPlay 2’s 3rd-party speaker support than this official list
Apple has confirmed which third-party connected speakers will be AirPlay 2 compatible, though the 33 models on the list isn’t quite the whole story. The new streaming functionality was added to iOS devices today as part of the iOS 11.4 release, allowing Apple’s HomePod speaker to integrate with a multi-room music setup, among other things.
One of the elements of AirPlay 2 that has had music-enthusiasts most eager, though, is its compatibility outside of Apple’s product portfolio. In addition to HomePod, there are 22 models from Bang & Olufsen, Denon, and others which are all officially confirmed to be supported. That means they’ll show up as playback options in the iOS Control Center, as well as in music apps on iPhone and iPad. There’ll also be more from Beats, Bose, Devialet, and more, though exactly models haven’t been confirmed yet.
Of the list, the speakers most people are probably going to be looking for are those from Sonos. On that front there’s good news and bad. Yes, Sonos has pledged native support for AirPlay 2 – though the company tells me it hasn’t anything to announce as to when, exactly, it’ll be pushing its software update out to enable that streaming functionality – but only on three speakers from its current range.
First off there’s the Sonos One, the smart speaker which currently runs Amazon’s Alexa but which, eventually, is expected to get Google Assistant support too. Then there’s the Play:5, though specifically the second-generation one. Finally, there’s the Sonos Playbase, the company’s home theater speaker.
Unfortunately that means, if you have a Play:1, Play:3, a first-generation Play:5, or a Playbar, you’re out of luck when it comes to native AirPlay 2 support. That doesn’t mean you won’t be able to stream via AirPlay 2 to those speakers, however. It simply makes it a little more complicated.
That means, when you group an AirPlay 2-enabled Sonos speaker with older Sonos devices that don’t have native support, you’ll be able to stream that music to them all. It’s not quite a seamless update, no, but it’s definitely better than older speakers from the company being left out in the cold.
All the same, it’s worth noting that AirPlay 2 still operates differently to, say, using the Sonos app on your iPhone to control a group of Sonos-only speakers. In that situation, as with controlling one or more HomePod units, the speakers are responsible for directly connecting to the streaming source, whether that be Spotify, Apple Music, or something else. Even if the iPhone you used to set up a playlist through that streaming service disconnects from the same WiFi network as the speakers, their playback can continue.
AirPlay 2, however, won’t work that way with connected speakers other than HomePod. Instead, the iPhone – or whatever iOS device you’re using to manage the music – sits in-between the streaming service and the third-party speakers, effectively pulling down the music and then redistributing it to them. At the moment it doesn’t look like a HomePod can take over that responsibility should you need to leave with your iPhone but leave the music playing, though who knows what Apple has in mind for WWDC 2023 next week.

Mesh Elite Skylake Pca Skylake Gaming Pc Review
Pros
Cons
Our Verdict
At £999 without a monitor, the Mesh Elite Skylake PCA is one of the most expensive PCs in our group test, but its features and build quality most certainly earn that price tag. Its feels like a higher-quality system and the high-end internal components deliver useful additional capabilities and bags of upgrade potential.
It may not resemble a gaming PC at first glance, but the Mesh Elite Skylake PCA exudes quality. Its tower case comes with a matt black finished that’s soft to the touch, giving it an expensive feel, while at the top an illuminated display shows the current CPU temperature in a variety of colours which can be altered at the push of a button. Also see: Best gaming PCs 2023/2023.
Unlike most of the gaming PCs we review, the case has no transparent side panel. It’s a real shame in this case, because the Mesh Skylake PCA is by far the most impressive-looking inside. The case is spacious, with plenty of available drive bays and the Gigabyte GA-Z170X-Gaming 3 motherboard features attractive red and black details. Most impressive though is the Raijintek Triton 250mm high performance all-in-one CPU cooler, its two transparent pipes fat and filled with striking blue coolant. There’s also a blue downlight which illuminates the desk surface from the bottom of the case. We’d say the build quality of this case is considerably higher than most, certainly a tier above those from Cyberpower and Chillblast.
Under that fancy cooler lurks an Intel Core-i5 6600K Skylake processor, overclocked from 3.5GHz to 4.4GHz. This yields a decent boost in performance without pushing components to the absolute limit. It’s coupled with 16GB of 2400MHz DDR4 RAM – a little faster than the base 2133MHz stuff found in lower-end systems and comes with a 250GB Samsung SSD backed by a 1TB Seagate hard drive. Although the SSD uses one of the two M.2 ports on the motherboard, it’s using the SATA interface, rather than PCI-E so it can’t match the raw performance of the Samsung 128GB SM951 used by Chillblast. However it does perform very well and its extra capacity may well prove more beneficial than extra speed. See all PC reviews.
Mesh has opted for the ever-popular Nvidia GeForce GTX 970 graphics card in the Elite Skylake PCA, and in this case it’s a Palit-branded model running at standard clock speeds, rather than the boosted speeds found in some competitors’ systems.
Mesh’s chosen motherboard doesn’t just look good, it’s also designed specifically for gaming and comes with a selection of features not found on lesser models. Not only does it support USB 3.1, but it also supports USB 3.1 Gen 2 which allows for speeds of up to 10Gb/s and up to a claimed 16 Gb/s using Intel’s USB 3.1 controller. It also supports both USB Type-C and Type-A connectors.
Audio quality has also been boosted, claiming 115dB signal to noise ratio and featuring support for the Sound Blaster X-Fi MB3 audio suite. The OP-Amp chips have also been made user-upgradable, so if you want the very best sound quality, you can swap them out for higher-fidelity alternatives of your choice. See all gaming PC reviews.
If you prefer to use an external USB audio device, you can use Gigabytes, “DAC-UP” USB ports which feature isolated power supplies to ensure there’s no interference from other components.
The board also includes a high-performance “Killer Ethernet” network interface, designed to reduce latency and improve overall system performance and is one of the few reviewed here to offer 2-way Nvidia SLI certification, allowing the addition of an extra GTX 970 as a future upgrade. The supplied 750W power supply also provides plenty of upgrade potential.
The Mesh Elite Skylake PCA is a great performer, but not the fastest overall. Chillblast’s Fusion Krypton, for example, beats is in the application performance tests, probably due to its faster SSD, and also beats it by a few fps in gaming, thanks to its factory overclocked card. The Mesh system does come with double the amount of SSD storage however, which means more games can be installed on it for much faster loading times.
Performance in our tests was as follows: PCMark 8 2.0 Home: 5316; PCMark8 2.0 Work: 5748; PCMark8 2.0 Creative: 7282; PCMark8 2.0 Storage: 4996; Alien vs Predator 1080/720: 89.6/169.6fps; Sniper Elite V2 Ultra/Medium/Low: 47.6/203.2/444.7fps; Final Fantasy XIV Creation Benchmark Maximum: 130.4fps; 3DMark Fire Strike Ultra/Fire StrikeExtreme/Fire Strike/Sky Diver/Cloud Gate/Ice Storm Unlimited/Ice Storm Extreme/Ice Storm: 2,588/4,919/9,494/24,308/23,574/207,151/183,687/194,602; max CPU temp under load: 51ºC; power consumption idle/load: 63/251W

Python Tuple – Pack, Unpack, Compare, Slicing, Delete, Key
What is Tuple Matching in Python?
Tuple Matching in Python is a method of grouping the tuples by matching the second element in the tuples. It is achieved by using a dictionary by checking the second element in each tuple in python programming. However, we can make new tuples by taking portions of existing tuples.
Tuple Syntax
Tup = ('Jan','feb','march')To write an empty tuple, you need to write as two parentheses containing nothing-
tup1 = ();For writing tuple for a single value, you need to include a comma, even though there is a single value. Also at the end you need to write semicolon as shown below.
Tup1 = (50,);Tuple indices begin at 0, and they can be concatenated, sliced and so on.
Tuple Assignment
Python has tuple assignment feature which enables you to assign more than one variable at a time. In here, we have assigned tuple 1 with the persons information like name, surname, birth year, etc. and another tuple 2 with the values in it like number (1,2,3,….,7).
For Example,
(name, surname, birth year, favorite movie and year, profession, birthplace) = Robert
Here is the code,
tup1 = ('Robert', 'Carlos','1965','Terminator 1995', 'Actor','Florida'); tup2 = (1,2,3,4,5,6,7); print(tup1[0]) print(tup2[1:4])
Tuple 1 includes list of information of Robert
Tuple 2 includes list of numbers in it
We call the value for [0] in tuple and for tuple 2 we call the value between 1 and 4
Run the code- It gives name Robert for first tuple while for second tuple it gives number (2,3 and 4)
Packing and UnpackingIn packing, we place value into a new tuple while in unpacking we extract those values back into variables.
x = ("Guru99", 20, "Education") # tuple packing (company, emp, profile) = x # tuple unpacking print(company) print(emp) print(profile) Comparing tuplesA comparison operator in Python can work with tuples.
It starts with comparing the first element from each of the tuples
Let’s study this with an example-
#case 1
a=(5,6) b=(1,4) else: print("b is bigger")#case 2
a=(5,6) b=(5,4) else: print ("b is bigger")#case 3
a=(5,6) b=(6,4) else: print("b is bigger") Using tuples as keys in dictionariesSince tuples are hashable, and list is not, we must use tuple as the key if we need to create a composite key to use in a dictionary.
Example: We would come across a composite key if we need to create a telephone directory that maps, first-name, last-name, pairs of telephone numbers, etc. Assuming that we have declared the variables as last and first number, we could write a dictionary assignment statement as shown below:
directory[last,first] = numberInside the brackets, the expression is a tuple. We could use tuple assignment in a for loop to navigate this dictionary.
for last, first in directory: print first, last, directory[last, first]This loop navigates the keys in the directory, which are tuples. It assigns the elements of each tuple to last and first and then prints the name and corresponding telephone number.
Tuples and dictionary
Dictionary can return the list of tuples by calling items, where each tuple is a key value pair.
a = {'x':100, 'y':200} b = list(a.items()) print(b) Deleting TuplesTuples are immutable and cannot be deleted. You cannot delete or remove items from a tuple. But deleting tuple entirely is possible by using the keyword
del Slicing of TupleTo fetch specific sets of sub-elements from tuple or list, we use this unique function called slicing. Slicing is not only applicable to tuple but also for array and list.
x = ("a", "b","c", "d", "e") print(x[2:4])The output of this code will be (‘c’, ‘d’).
Here is the Python 2 Code for all above example
tup1 = ('Robert', 'Carlos','1965','Terminator 1995', 'Actor','Florida'); tup2 = (1,2,3,4,5,6,7); print tup1[0] print tup2[1:4] #Packing and Unpacking x = ("Guru99", 20, "Education") # tuple packing (company, emp, profile) = x # tuple unpacking print company print emp print profile #Comparing tuples #case 1 a=(5,6) b=(1,4) else: print "b is bigger" #case 2 a=(5,6) b=(5,4) else: print "b is bigger" #case 3 a=(5,6) b=(6,4) else: print "b is bigger" #Tuples and dictionary a = {'x':100, 'y':200} b = a.items() print b #Slicing of Tuple x = ("a", "b","c", "d", "e") print x[2:4] Built-in functions with TupleTo perform different task, tuple allows you to use many built-in functions like all(), any(), enumerate(), max(), min(), sorted(), len(), tuple(), etc.
Advantages of tuple over list
Iterating through tuple is faster than with list, since tuples are immutable.
Tuples that consist of immutable elements can be used as key for dictionary, which is not possible with list
If you have data that is immutable, implementing it as tuple will guarantee that it remains write-protected
SummaryPython has tuple assignment feature which enables you to assign more than one variable at a time.
Packing and Unpacking of Tuples
In packing, we place value into a new tuple while in unpacking we extract those values back into variables.
A comparison operator in Python can work with tuples.
Using tuples as keys in dictionaries
Tuples are hashable, and list are not
