ATSC 3.0 ALP ATSC 3.0 Receiving Expense ALP Standard Automatic Switching Device and Method

摘要

The present invention relates to an ALP standard automatic switching device and method for ATSC 3.0 receiving equipment, comprising: a packet type determination module that determines whether a packet type of an input signal is link layer signaling, and is input according to an output signal of the packet type determination module. When the signal is link layer signaling, a signaling type determination module that determines whether the signaling type is LMT or ROHC-U and outputs a corresponding signal, and a signaling type determination module in a signal transmitted from the signaling type determination module, and a length according to the determination. Length calculation module to be calculated, when the length of each signaling type in the calculated length is greater than the payload length by 5 A/330 2015 judgment module that determines A/330 2015, when it is A/330 2018 from the signal transmitted through the judgment module ALP standard automatic conversion device for ATSC 3.0 receiving equipment consisting of a conversion module that transmits directly to the A/330 2018 device and in the case of A/330 2015, subtracts 5 from the payload length and sends it to the A/330 2018 processor. And a method.
