If  the  user  swicthes  to  another  channel  while  an  HbbTv  
application  is  active  (either  in  red  button  icon  mode  
or  full  UI  mode),  the  following  scenarios  can  occur.
-­  The  application  can  continue  running.
-­  The  application  can  be  terminated.
-­   The   application   can   be   terminated   and   another  
autostart  red  button  application  can  be  launched.            
HbbTv   allows   the   applications   to   be   retrieved   both  
from  broadband  or  broadcast.  The  broadcaster  may  
enable  both  ways  or  one  of  them.  If  the  platfrom  does  
not  have  an  operational  broadband  connection,  the  
platform  can  still  launch  applications  transmitted  on  
broadcast.  
The  autostart  red  button  applications  generally  provide  
links  to  other  applications.  An  example  of  this  is  shown  
below.  The  user  then  can  switch  to  other  applications  
by  using  the  links  provided.  The  applications  should  
provide  a  way  to  terminate  themselves,  usually  button  
0  is  used  for  this.

HbbTv  applications  use  keys  on  the  remote  control  to  
interact  with  the  user.  When  an  HbbTv  applications  is  
launched,  the  control  of  some  keys  are  owned  by  the  
application.  For  example,  numeric  channel  selection  
may   not   work   on   a   teletect   application   where   the  
numbers  indicate  teletext  pages.  
HbbTv   requires   AV   streaming   capability   for   the  
platform.  There  are  numerous  applications  providing  
VOD  (video  on  demand)  and  catch-­up  TV  services.  
The   user   can   use   play,   pause,   stop,   forward,   and  
rewind   keys   on   the   remote   control   to   interact   with  
the  AV  content.
