To keep up with Americans' changing TV-watching habits, Dallas-based AT&T will launch a new product in November that will allow people to stream their favorite shows and movies without a cable box or satellite dish. The new video service -- called DirecTV Now -- has gotten more attention in light of the Time Warner merger news that would give AT&T ownership of valuable TV brands, such as HBO and CNN.

AT&T chief executive Randall Stephenson said the video streaming product will appeal to the approximately 20 million U.S. households who don't have pay TV. DirecTV Now will have more than 100 channels and cost $35 a month.

So far, ten networks and program providers have announced their content will be part of the DirecTV Now lineup. They include Disney, HBO, Discovery Networks, NBC Universal, Turner, Scripps Networks, A+E Networks, STARZ, AMC and Viacom. They have announced the deals with AT&T in news releases, earnings calls and public remarks. The streaming service will also feature Time Warner content other than HBO, but it is not clear what that will be.

During Disney's 3Q earnings call, Disney CEO Bob Iger said DirecTV Now will include ESPN, ESPN2, ABC, Freeform, Disney Channel, Disney XD, and Disney Junior.

Under A&E networks, A&E, Lifetime, History, LMN, FYI and VICELAND will all be available to DirecTV Now customers.

From Scripps Networks, HGTV, Food Network, Travel Channel, DIY Network, Cooking Channel and Great American Country will be included in the DirecTV Now lineup.

It's not clear which Discovery Communications channels would be available for DirecTV Now customers, but they could include: The Discovery Channel, TLC, Investigation Discovery, Animal Planet, Science and Turbo/Velocity and OWN: Oprah Winfrey Network.

Here's more of what we know -- and don't know -- about the new video streaming product that launches in late November:

WHAT WE KNOW

- AT&T will launch three new video streaming options (also known as subscription video on demand services). Each will have a different price and different number of channels. Two of them will charge a monthly rate. A third streaming option, called Freeview, will be free and ad-supported.

- Customers won't need a cable box or satellite dish, but they will need internet. The new products are all over-the-top products, a term used for TV services that don't require cable ( in other words, they go "over-the-top" of cable). Customers will stream TV over the internet, much like Netflix or Hulu. But they'll need broadband, another service that AT&T happens to sell.

- The app will allow customers to watch live TV and on-demand programs. AT&T executives have also said that customers will be able to pay for add-on content.

- DirecTV Now -- AT&T's most complete option for those who don't want cable or a dish -- will cost $35 per month for 100-plus channels. The price is much less than the $50 to $60 per month fee that analysts had predicted. The channels haven't been announced, but CEO Randall Stephenson recently described the channels as "premium content" and said "This isn't the junk nobody wants."

- The new streaming service will be mobile-first. The idea is to make it easier for people to watch TV when they want, where they want and how they want. That means on smartphones and tablets, along with smart TVs.

- AT&T will waive data charges for the video streaming service -- but only if customers are also mobile customers. The company already offers the same perk to customers who stream video through the DirecTV app or pay for Fullscreen, a subscription video service featuring TV shows and original series intended for a teen and twenty-something audience.

- The over-the-top product will have fewer channels -- but it won't be skinny. Some video streaming services, such as Dish Network's Sling TV, offer a "skinny bundle" of only 25-plus channels. The slim packages are an alternative to the traditional TV business model, which offers hundreds of channels at a fixed price but with channels viewers may never watch. But Tony Goncalves, AT&T's senior vice president of strategy and business development for AT&T Entertainment Group, has said the economics don't work for skinny bundles. Instead, AT&T executives have described the new offering as "pay TV as an app."

- It is all part of AT&T's "TV Everywhere" effort. The company recently relaunched DirecTV's app, which is available to pay TV subscribers. It has new features that make TV-watching more portable. For example, it allows people to stream live TV, watch shows they recorded on their DVR and download shows to watch later, even without internet access.

WHAT WE DON'T KNOW

- We don't know the full lineup of channels for DirecTV Now -- or the other two streaming services.

- We don't know the price of the second streaming option -- or how many channels it will include.

- We don't know if the streaming services will have ads or commercials. (We do know the free one will be entirely ad-supported.)

- We don't know if the streaming services are compatible with devices like Apple TV and Amazon Fire TV and if so, which ones. (There have been some news reports about updates posted to the DirecTV Now website on Thursday. They have since been taken down, but the website indicated that DirecTV Now would be available on the Amazon Fire TV, Google Cast and Apple TV.)

- We don't know what special features the streaming services will have. For example, will they have a cloud-based DVR that allows customers to record programs and watch them later? Will viewers be able to pause live content or fast-forward through a show? Will the streaming service carry local news channels? All live sports events?
