Problems solved by technology

However, in the early stage of software development, generally speaking, the chip has not been selected, or the software and hardware of the entire system have not been jointly debugged, such as figure 1 As shown, the reception diagram of the DVB-H handheld device in the current prior art is given, from figure 1 It can be seen that the debugging of the IPDC protocol stack is difficult

Embodiment Construction

[0022] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] The essence of the present invention is a TS (Transport Stream / transport stream) stream analysis software, by reading in a standard TS stream file conforming to the DVB-H protocol, and parsing out the INT (IP Notification Table / IP notification form) form wherein, The IP data packet mapped by the table is parsed from the TS stream, and then broadcast to a wired network such as Ethernet.

[0024] If the DVB-H protocol stack that needs to be debugged can run on a PC, then you can directly receive the DVB-H IP data packets broadcast by the Ethernet through the PC for debugging; or the handheld device for debugging the DVB-H protocol stack can be connected to the ...

Abstract

The invention provides a hand-hold digital television broadcast wireless signal analogy method and a device thereof, and an application method and a method for debugging IP data transmission protocol stack of the device and a device thereof. The hand-hold digital television broadcast wireless signal analogy method comprises the steps that step S202, a transmission stream file is read, and the IP notification table in the transmission stream file is analyzed; step S204, a IP data packet is analyzed from the transmission stream file according to the IP notification table; step S206, the IP data packet which is analyzed is broadcasted on an Ethernet. Thus, the normal debugging on the Ethernet can be performed by utilizing a DVB-H development machine to receive a DVB-H data packet.

Description

technical field [0001] The present invention relates to the field of DVB-H (Digital Video Broadcasting-Handheld / handheld digital TV broadcasting) wireless communication, more specifically, to a method and device for simulating wireless signals of handheld digital TV broadcasting, and IP data transmission using the method and device Protocol stack debugging method and device. Background technique [0002] With the popularization of the third generation mobile communication (Third generation, 3G for short) technology in the world, more and more users start to watch mobile TV through the 3G network. Soon, operators discovered that more users watched TV on 3G networks, which not only took up valuable 3G bandwidth, but also brought high charges to users. [0003] DVB-H is a terrestrial digital TV broadcasting technology with low network construction costs and one-way broadcasting. It not only does not occupy the two-way bandwidth of the mobile communication network, but also all...
