Embodiment Construction

[0057] The present invention will be described in further detail below by means of specific embodiments:

[0058] This embodiment shows an IP data encapsulation method applied to IP over DVB transmission, and the IP data in this embodiment is accessed through Ethernet.

[0059] Such as Figure 4 As shown, the encapsulation process of converting IP data into TS streams in this embodiment is as follows:

[0060] Step 101: Ethernet data preprocessing step, remove the preamble and FCS domain from the Ethernet data frame obtained from the Ethernet physical layer PHY chip, and then obtain the IP data frame, and count the frame length of the IP data frame to generate Signals such as IP data validity and frame end indication.

[0061] Step 102: IP data frame buffering step, the frame length information of IP data and IP data is stored in RAM, carries out next step (step 103) when depositing a complete IP data frame in RAM;

[0062] It is worth noting that the frequency of the downs...

Abstract

This patent relates to the technical field of data transmission, and specifically discloses an IP data encapsulation method applied to IP over DVB transmission, including: step 1, obtaining IP data frames from Ethernet data frames; It is split into multiple data loads and encapsulated into a TS flow data in turn; the invention also discloses an IP data restoration method for IP over DVB transmission and an IP transparent transmission system accordingly. The invention solves the technical problem that the protocol overhead required for IP over DVB transmission is too high in the prior art, and realizes the transparent transmission of IP data applicable to DVB, DTMB and other transmission systems with relatively small protocol overhead.

Description

technical field [0001] The invention relates to the technical field of data transmission, and specifically discloses an IP data encapsulation method, restoration method and system applied to IP over DVB transmission. Background technique [0002] DVB (Digital Video Broadcasting, Digital Video Broadcasting) is a series of digital television standards formulated in Europe. The DVB system supports audio and video transmission, and its transmission format is TS (Transport Stream) flow. TS stream is a standard format for storing and transmitting audio and video data. Most of the existing wireless image transmission systems use TS stream as the standard format. The TS packet (Packet) in the TS stream has a fixed length of 188 bytes, including a 4-byte header and a 184-byte data load. The packet header includes information such as synchronization byte 47, packet PID (Packet Identifier, packet identifier code), and packet continuous counting. [0003] The DVB system only supports...
