 +===== Important =====
 +This information in this page relates to the first release of the DTVkit TunerHAL implementation. This is an alpha release and has primarily been tested using the Android emulator. The Android emulator has certain restrictions in that only H264 video is currently supported and audio is not supported for broadcast media formats. The release has been made available for members that want to experiment with the code at an early stage. The release makes use of a modified version of the Android 'TunerHAL' code that enables transport stream data to be read from a file. With this the DTVkit release can be run in the Android Emulator, it is then possible to 'tune' to the file source, receive SI/EPG information, decode video (H264), and change channel. The code base is currently being tested on reference hardware and will be updated in due course.
