Increasing slots will not increase popularity. The popularity of MPEG-4 will increase as the user base increases. Currently MPEG-2 is leading in User Base. And I think that as long as MPEG-2 remains, MPEG-4 will not gain popularity at any cost. Prasar bharati should discontinue Private channels from MPEG-2 and continue with only one TP and available only DD Channels. After this people will be forced to go to MPEG-4. Almost the whole world has left MPEG-2 platform and Prasar Bharati should also leave MPEG-2 as soon as possible.
