After bug 1197772 implemented, we need to dispatch these input events from the client-side page to the correct input field which is currently focused on TV. The idea is to utilize mozInputMethod API.

Please refer to https://github.com/luke-chang/ajax-websocket-test For now, we have achieved that inputting arbitrary string in the client-side page and the string will show on the TV successfully. However, we have some issues need to be addressed: - once the string is sent, the software keyboard on the TV becomes ineffective until re-launch it. - even the software keyboard recovers after re-launching, we can still see some error messages in console logs every time the keyboard shows up.

This issue has been fixed. > - even the software keyboard recovers after re-launching, we can still see > some error messages in console logs every time the keyboard shows up. I found that it's a long-standing issue which happens whenever we enable two keyboard apps so we may not need to take care of it in this bug.
