Ahead of Apple launching its big video streaming initiative Apple TV+ this autumn, an integration is going live today that brings Apple closer to working with third-party TV makers and making its services available on a wider array of devices. Today Vizio said it would start to roll out support for AirPlay2 and HomeKit to its SmartCast TV sets, making it possible to stream video and other media from Apple devices to its TVs and control the sets using Apple’s Home app and through its Siri voice assistant.

The support is coming by way of an over-the-air update to SmartCast 3.0, the system that underpins Vizio’s smart TVs. Notably, using the Apple services will not necessarily mean buying new Vizio TVs: the service is backwards-compatible to TVs dating back to 2016. New sets range in prices from $259.99 to $3,499.99.

“SmartCast 3.0 is full of added value for VIZIO customers. With both AirPlay 2 and HomeKit support, users can now share movies, TV shows, music and more from their favorite apps, including the Apple TV app, directly to SmartCast TVs, and enable TV controls through the Home app and Siri,” said Bill Baxter, chief technology officer, VIZIO. “We are thrilled to offer an even more compelling value proposition to our users with a smart TV experience that supports all three major voice assistants. This broad range of compatibility enables VIZIO SmartCast to seamlessly integrate into any household with Siri, Google Assistant or Alexa — giving users more ways to sit back and enjoy the entertainment they love.” Vizio still appears to be the only smart TV maker that’s offering support on its sets for all of the major voice assistants.

Vizio’s integration for Apple’s media services was first announced in January at CES, when Vizio said it would be getting rolled out later in the year.

The news was notable at the time for a couple of reasons. First, it underscored how Vizio was stepping up its growth efforts after a tough couple of years involving lawsuits, regulatory investigations and a failed M&A attempt.

Second, it was part of a bigger theme of Apple branching out into a wider consumer electronics ecosystem for its push into the world of TV and video. The latter still stands in stark contrast to Apple’s approach around smartphones, computers and watches, where it has spent years building hardware, operating systems and walled gardens.

That’s a story that is still playing out. The timing of the Vizio news is notable given that it’s just one day after Apple’s quarterly earnings report, where the company revealed a solid quarter that beat analyst expectations but also continued to show slowing growth, largely on the back of an ongoing decline in unit sales for the iPhone (amid a similar, bigger market trend for smartphones overall). To offset that story, Apple has been working hard to build new product categories in newer hardware areas like wearables (the Apple Watch), smart home hubs (HomePod) and Services, which includes Apple’s efforts in areas like video and music.

Services came in at $11.455 billion — missing analysts expectations but still growing 13% on a year ago. The promise — or perhaps more accurately, the hope — is that adding TV and gaming into the mix later in the year will boost that even more. This is where integrations such as the one getting announced today with Vizio will fit in: they will help expand the number of people who might be using the services, and of course the number of screens where the content can be consumed.

Vizio does not specify how many sets it currently has in the market — the last number it gave me earlier in the year was “millions” — but it generally is behind Samsung, which currently leads in the smart TV category.

It notes that the service will work by way of tapping an AirPlay icon within SmartCast to be able to stream 4K and Dolby VisionTM HDR movies and TV shows from Apple TV, along with other AirPlay-compatible video apps. Mirroring (which you can also do with non-smart TVs) will also be supported. AirPlay 2 also lets users play content across multiple rooms (provided you have the sets, HomePods or other AirPlay 2 speakers installed).
