METHOD FOR PROCESSING SI CHANNEL LIST IN CABLE DIGITAL TV USING PROFILE 1

摘要

A cable broadcast receiver includes a host device and a cable card which is detachably inserted into the host device. The cable card receives an OOB (out of band) signal from the host device and parses a new SI (service information) table from the OOB signal. The new SI table contains a first CRC (cyclic redundancy check) code. The host device includes a memory and a controller. The memory pre-stores a channel list which is generated based on a previous SI table containing a second CRC code. The controller receives the new SI table from the cable card, and updates the pre-stored channel list based on the new SI table when there is a difference between the first and second CRC codes. The previous and new SI tables may correspond to Profile 1 service information and may include SVCTs (short form virtual channel tables) or NITs (network information tables).
