Title:
MULTICAST SIGNAL PROCESSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/239983
Kind Code:
A1
Abstract:
A multicast signal transmission method, according to the embodiments, may comprise the steps of: receiving Internet Protocol (IP) streams from an upper layer; compressing, at a link layer, IP headers of the IP streams; generating link control information for link layer-related multicast; encapsulating IP header-compressed Robust Header Compression (ROHC) streams; encapsulating the link control information and an IP header compression-related descriptor; and transmitting, in a physical layer, a stream including the link control information, the descriptor and the ROHC streams. A multicast signal reception method, according to the embodiments, comprises the steps of: receiving a multicast signal from a physical layer; decompressing, at a link layer, IP headers of IP streams of the multicast signal; and parsing link control information for multicast, and an IP header compression-related descriptor, wherein IP header-compressed ROHC streams may be decapsulated.
