Abstract

The invention comprises: a digital program releasing side for using Transport Stream signals to send associated information about Physical Channel and Virtual Channel to; a digital program receiving device for receiving the Transport Stream and tuning the TV program to the Physical Channel mapped by the Virtual Channel with the associated information about Physical Channel and Virtual Channel.

Description

1. Technical field [0001] The present invention relates to digital programs, and more specifically relates to a channel tuning device for digital programs and a control method thereof. 2. Background technology [0002] Recently, with the rapid development of digital programs, various channels have appeared, and the number of channels is rapidly increasing. [0003] Furthermore, the secondary (minor) channel included in the main (major) channel was introduced, and even reached the realm of proposing the concepts of physical channel (Physical CH) and virtual channel (Virtual CH). The physical channel of the digital program is different from the original analog program, and the user needs to separately identify the channel number of the digital program. But in fact, it is impossible for users to identify the above-mentioned numerous channels. It is better to maintain the identification method of the original analog channel number, so a virtual channel is adopted. [0004] fi...
