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] like 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 downstre...

Abstract

The invention relates to the technical field of data transmission, and particularly discloses an IP data packaging method applied to IP over DVB transmission, which comprises the following steps: step1, acquiring an IP data frame from an Ethernet data frame; and 2, sequentially splitting the IP data frame into a plurality of data loads, and sequentially packaging the data loads into TS stream data. The invention further correspondingly discloses an IP data recovery method for IP over DVB transmission and an IP transparent transmission system. The technical problem that in the prior art, protocol expenditure needed by IP over DVB transmission is too high is solved, and IP data transparent transmission capable of being applied to transmission systems such as DVB and DTMB is achieved with small protocol expenditure.

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 payload. 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 suppo...
