Abstract

The invention provides a transmission method and device based on SMT protocol and ALC protocol compatibility, and the method comprises the steps: carrying out the protocol packaging based on an SMT transmission protocol or / and carrying out the protocol packaging based on an ALC transmission protocol when the method is used at a transmitting end, and forming a compatible transmission protocol package; configuring a protocol identification bit for distinguishing an SMT-based transmission protocol from an ALC-based transmission protocol at a corresponding bit of a packet header of the compatibletransmission protocol packet; and sending a compatible transmission protocol packet formed by performing protocol encapsulation on the SMT-based transmission protocol or / and performing protocol encapsulation on the ALC-based transmission protocol to a receiving end. According to the invention, the reserved bit fields in the transmission protocol packet are defined, so that the received data adopting two different transmission protocols are distinguished on the terminal side, the compatibility problem between systems supporting simultaneous or separate adoption of the two transmission protocolscan be effectively solved, and the protocol applicability of 5G broadcasting is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a transmission method and equipment compatible with the SMT protocol and the ALC protocol. Background technique [0002] With the continuous enhancement of the level of informatization, the arrival of the 5G era has become an irreversible technological trend, and the level of mutual integration of 5G mobile communications and broadcasting and television will inevitably continue to increase. The current mass media content provides users with more consumption options, and at the same time, the delivery and transmission of content is also facing new challenges. Therefore, efficient and scalable data transmission technology for 5G broadcasting is crucial to improving network transmission efficiency and user experience. [0003] Asynchronous Layered Coding (ALC) is a large-scale scalable reliable content transmission protocol developed by the International Organization f...
