After the invention of time-shifting, digital tv broadcasting was the largest factor to occur to TV since color – and, mixed with DVRs, it paved the way in which for additional evolution.

Digital tv introduced with it many benefits over analogue TV. The obvious for the buyer was an elevated image high quality and an growth of the variety of channels that may very well be broadcast on the identical time over the identical radio frequencies. Digital TV additionally enabled enhanced providers, usually accessed by the “crimson button” and a alternative of the teletext providers.

A number of specs battled it out for the digital TV crown within the 80s and 90s, with varied nations and areas adopting completely different requirements, nevertheless it wasn’t till 1998 that the primary digital broadcast was made within the UK.

The airwaves that carried fuzzy analogue TV now carry your cat gifs, breaking information and place-shifted video, however extra on that later.

Including Customized Part Headers

Mess around with the starter app and also you’ll observe:

  1. The app shows 20 images associated to every phrase search.
  2. It creates a brand new part in the identical UICollectionView for every search you carry out.

There aren’t any part headers within the UICollectionView. So to your first job, you’ll add a brand new part header utilizing the search textual content because the part title.

To show this part header, you’ll use UICollectionReusableView. This class is like UICollectionViewCell, besides it’s normally used to show headers and footers. Like cells, UICollectionView locations them in a reuse queue relatively than deleting them once they scroll out of the seen bounds.

You’ll add this ingredient on to the storyboard and create a subclass so it could possibly dynamically replace its title.

Making a UICollectionReusableView Class

Create a brand new file to characterize the customized class for the header.

  • Choose File ▸ New ▸ File. Choose Cocoa Contact Class.
  • Select Subclass of UICollectionReusableView.
  • Title the category FlickrPhotoHeaderView.
  • Go away Additionally create XIB file unchecked.
  • Choose Swift because the language.
  • Click on Subsequent.

Choose the starter app challenge’s Views folder and click on Create to create the file.

Next, open Main.storyboard and select the collecti

Subsequent, open Predominant.storyboard and choose the gathering view in FlickrPhotosViewController. Choose the Attributes inspector and, within the Equipment part, test the Part Header checkbox. Discover a Assortment Reusable View seems within the storyboard beneath the Assortment View.

Setting the Section Header View Class

Setting the Part Header View Class

Now, you’ll set your customized class because the part header view. To do that:

  • Choose the Assortment Reusable View added within the assortment view.
  • Open the Id inspector and set the Class within the Customized Class part to FlickrPhotoHeaderView.
  • Subsequent, within the Attributes inspector, set the Identifier to FlickrPhotoHeaderView.
  • Additionally set the Background shade to Opaque Separator Colour to provide it a pleasant offset from the remainder of the gathering view.
  • Open the Measurement inspector and set the Peak to 90.

Now open the Object library with the important thing mixture Command-Shift-L and drag a Label onto the reusable view. Use the Auto Format align button on the backside of the storyboard window to pin it to the horizontal and vertical heart of the view. Within the Attributes inspector of the label, replace the font to System 32.

Connecting the Section Header to Data

Connecting the Part Header to Knowledge

Open FlickrPhotoHeaderView.swift in a further editor pane and Management-drag from the label within the header view over to the file and title the outlet titleLabel. It’s going to add the next code:

Lastly, it’s essential implement a brand new information supply methodology to wire every thing collectively. Open FlickrPhotosViewController+UICollectionViewDataSource.swift and add the next methodology:

This methodology returns a view for a given form of supplementary view. For this app, you solely have headers, however you may as well have other forms of supplementary views.

Right here’s the breakdown of this methodology:

  1. Deal with the UICollectionView.elementKindSectionHeader type which UICollectionViewFlowLayout provides for you. By checking the header field in an earlier step, you advised the circulation structure to start supplying headers. If you happen to weren’t utilizing the circulation structure, you wouldn’t get this habits totally free.
  2. Dequeue the header utilizing the storyboard identifier.
  3. Examine that the view is the fitting kind and, if not, merely return it.
  4. Set the search time period because the textual content on the view’s label.
  5. Assert within the case that the sort was not what was anticipated.

This can be a good place to construct and run. You’ll get a pleasant part header for every search, and the structure adapts properly in rotation eventualities on all machine varieties:

Bravo! It’s a small change, but the app looks so m

Bravo! It’s a small change, however the app seems so a lot better now, doesn’t it? :]

However there’s extra work to do!

Black and white tv continued to enhance, nevertheless it wasn’t till 1954 that the primary color broadcasts had been launched within the US. The system used a brand new Nationwide Television Programs Committee (NTSC) commonplace encoding brightness and color individually in order that black and white TVs may use the sign too.

A European color commonplace wasn’t set till 1963 with Part Alternating Line (PAL), which was technically superior and in a position to cope with climate higher than NTSC. Color broadcasts didn’t begin in Europe till 1967 with BBC2 changing into the primary channel within the UK to broadcast in color, spearheaded by then-controller Sir David Attenborough.

Color tv continued to enhance in high quality, with screens changing into bigger and sharper, cameras extra delicate, and broadcasts stronger for higher image high quality.

The setup

Setup for each units entails connecting cables out of your video supply to the Slingbox, connecting the Slingbox to your own home community, and creating an account with Sling Media to configure and determine your Slingbox to the participant software program.

For the video supply hookup, Sling offers element and composite video cables, plus stereo audio cables, with each fashions. You join the cables to the applicable outputs on the video supply, and the inputs on the Slingbox. For video sources that don’t have spare video outputs, Sling has outfitted each Slingboxes with video-outputs in addition to inputs, so you’ll be able to put the Slingbox in between the TV set and the video supply by connecting cables from the video supply to the Slingbox’s video inputs, after which working the cables you’d beforehand used with the TV between the Slingbox’s video outputs and the TV inputs.

On the Slingbox 350—a smallish (about 7 by 5 by 2 inches) rectangular field with an uncommon honeycomb-style floor—these are your solely video hookup choices. However the bigger, matte-surfaced Slingbox 500, which seems like a normal set-top field that somebody has grabbed by reverse corners and twisted (and is subsequently a bit onerous to stack on high of different parts), additionally comes with an HDMI cable to make use of with the unit’s HDMI pass-through ports to put the Slingbox between an HDMI video supply and TV. However though you’ll be able to allow the HDMI enter because the content material supply for the Slingbox 500, Sling recommends not doing so—as a substitute, the corporate advises hooking up the element video cables as effectively and getting the video stream from them.

Why? As a result of the Slingbox doesn’t circumvent HDCP, the copy-protection know-how constructed into HDMI connections to forestall unauthorized use of high-def digital content material. That signifies that you wouldn’t have the ability to view HDCP-protected content material (coming out of your cable or satellite tv for pc field, say) remotely. Utilizing the element video outputs bypasses the issue—content material suppliers have to date been content material to let analog video renderings out within the wild.

So why hassle with the HDMI connections in any respect? The thought is to provide the Slingbox 500 an HDMI enter of its personal, with out taking on a further HDMI port (in addition to the one you had been in all probability utilizing along with your HD video supply anyway). The speedy good thing about that enter is to permit you to arrange the Slingbox 500 utilizing the TV display screen and a small included distant, a lot the way in which you arrange most set-top bins. This can be a first for a Slingbox: With different fashions, you need to handle setup through the Internet browser of a pc on the identical community because the Slingbox.

The SlingBox 500 additionally permits you to view media in your iOS or Android machine utilizing a SlingPlayer characteristic known as SlingProjector. Merely faucet the SlingProjector button, select the media (your photograph stream, for instance) and SlingProjector begins displaying it. SlingProjector hadn’t but been enabled for movies once I examined it (Sling Media says video help will come someday after launch in a firmware replace), nevertheless it labored completely with nonetheless images, providing you with the choice of exhibiting them as a slideshow or one after the other.

Going ahead, the Slingbox 500 can even have the ability to perform as a media streamer in its personal proper. A USB port will help playback of media on a flash drive, both on the Slingbox-connected TV or remotely through the SlingPlayer (the Slingbox 350 has a USB port for distant playback solely). This performance had not but been enabled on my analysis unit, however can be due in a firmware replace. Presumably Sling Media will pursue agreements with different Web content material suppliers—I wouldn’t be stunned to see Netflix or Amazon On the spot Video help within the close to future.

Setup, no matter whether or not you do it on a TV with the Slingbox 500 or a pc with the 350, takes only some minutes you probably have details about your video supply helpful (make and mannequin particulars). You will need to additionally confirm a wired community connection or, in case you’re utilizing the Slingbox 500’s Wi-Fi, scan for your community and enter its password. The five hundred helps 802.11n on each the two.4GHz and 5GHz bands, and I’d suggest utilizing the latter in case you’re in a metropolis or any setting with numerous close by 2.4GHz networks. (I’d additionally suggest organising a wired connection, if in any respect doable, to enhance the reliability of your streaming connection.) There was no annoying messing with router settings—the connection simply occurred.

One other welcome enchancment in each fashions is the strong built-in infrared (IR) help for transmitting distant management instructions to the video supply. Earlier fashions relied on connecting an included IR blaster—a wire with terminals that may transmit IR alerts to imitate these produced by a distant management. IR blasters work effectively, however are susceptible to getting disconnected by issues like wandering pets. The brand new fashions nonetheless include an IR blaster, however the built-in IR help is so good I didn’t want to attach the blaster—though the Slingboxes weren’t proper in entrance of their respective video sources.
