Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] In the embodiment of the present invention, the sending end encodes the data in packets and sends them to the receiving end, and the receiving end decodes the corresponding packets to restore the lost data during transmission, so that the receiving end has a certain ability to recover data by itself, and For the data that cannot be recovered directly through packet decoding, the data transmission is completed by means of supplementary data retransmission, so as to effectively solve the problem of packet loss in the process of data transmission under the premise of ensuring the real-time perfo...

Abstract

The invention is applicable for the data transmission field, and provides a data transmitting method, a device and a system. The method includes generating a second data after grouping and encoding a first data; sending the second data to a receiving end, so that the receiving end receives a third data obtained through the transmission of the second data; receiving feedback information returning after the third data which is grouped and decoded by the receiving end; determining whether the feedback information carries requirements for resending the second data; and resending the second data to the receiving end, when the feedback information carries the requirements for resending the second data. The data transmission method, the device and the system effectively solve the problem of incomplete data caused by packet loss in the data transmission process, on the premise of guaranteeing the data transmission timeliness.

Description

technical field [0001] The invention belongs to the field of data transmission, and in particular relates to a data transmission method, device and system. Background technique [0002] With the rapid development of software and hardware technology, broadband voice, high-resolution video and high frame rate video have been applied to multimedia communication systems such as video conferencing systems, video surveillance systems or real-time command and dispatch systems, bringing data transmission volume The substantial improvement of the data transmission has also made the real-time, effectiveness, continuity and fluency of data transmission the key technical indicators to measure the performance of the above-mentioned systems. [0003] Existing multimedia communication systems mostly use Realtime Transfer Protocol (Realtime Transfer Protocol, RTP), Realtime Transfer Control Protocol (Realtime Transfer Control Protocol, RTCP) or Transmission Control Protocol (Transmission Co...
