TV articles change

- Removed obsolete article about TV Emulator (new one is published already),
- Extended article with info about supported adaptive bitrate streaming and drm formats in the TV Store,
We push platforms to require particular ABR and DRM formats, as specified in this document, the market is fragmented, some devices supports few more options even but we don't want to use them in practice. 

Don't think it is that important for content makers so propose to rephrase it to:

"Below you can find the list of supported ABR formats and their combinations with the DRM, together with simple examples how to correctly use such videos into your application. Please note, that the actual support may slightly differ, depending on specific video stream parameters, firmware versions and device generations. It is also important that not all devices TV Store runs at support ABD and DRM."
