ABSTRACT:
A system and method of reducing a channel switching delay in TDM mobile television systems comprises transmitting a sequence of data bursts associated with channels for reception on a RF channel bandwidth received on a mobile television receiver; switching between an active state of transmission and a non-active state of transmission during reception of channels on the RF channel bandwidth, wherein the active state of transmission comprises transmission of data bursts associated with user-preferred channels and the non-active state of transmission comprises transmission of data bursts associated with user non-preferred channels; anticipating a particular user-preferred channel that a user will likely switch to during reception of channels on the RF channel bandwidth; decoding the sequence of data bursts during the active state of transmission; buffering one decoded data burst for each of the user-preferred channels; and replacing a previously buffered data burst with a newly buffered data burst.
