Digital video broadcasting-terrestrial (DVB-T) is an ideal carrier for services requiring both high data rate and high mobility. Combined with other media as a return channel for user requests and acknowledgement signaling, DVB-T can supply interactive data services. With the exploitation of all available DVB channels, huge Internet access bandwidth can be provided, and it can be a highly recommendable candidate of future 4G/5G communications. In order to fully employ all channels, the profit oriented bandwidth allocation method (POBAM) with linear complexity is given for real-time joint channel bandwidth management. Simulation results powerfully show that POBAM can effectively exploit the multichannel resources for near global maximization of profit, and can effectively provide QoS differentiation. Besides, the joint channel bandwidth management outperforms the separate channel bandwidth management greatly. The complexity of POBAM is low enough for real time multichannel bandwidth management even when there're dozens of joint channels and hundreds of active users.
