Abstract

The embodiment of the invention provides an image transmission method and device for a remote desktop. The method includes the following steps that: format type recognition is performed on a source data to be transmitted; when the source data are recognized as image-format data, coding processing is performed on the image-format data through adopting a lossy coding technique; and data code streams which have been subjected to the coding processing are transmitted to a client end. According to the image transmission method and device for the remote desktop, the format type recognition is performed on the source data to be transmitted before the coding processing, and different processing is performed according to source data of different format types, when the source data are recognized as the image-format data, and the coding processing is performed on the image-format data through adopting the lossy coding technique, and the data code streams which have been subjected to the coding processing are transmitted to the client end, and therefore, compression ratio can be improved, so transmission efficiency can be also improved, and transmission delay can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies, and in particular to a remote desktop image transmission method and device. Background technique [0002] In recent years, remote desktop technology has gradually been widely used in application scenarios such as mobile office and office automation. The desktop sharing technology is mature and does not require high terminal equipment. It is widely used in various mobile terminals and 3G network settings. [0003] Due to the huge amount of computer image sequence data, it is very easy to cause network congestion and transmission delay during Internet network transmission, so the image must be effectively compressed and encoded before real-time transmission. Compressing and encoding image data is one of the main means to reduce bandwidth and expand applications. The low bandwidth and high performance of the Remote Desktop Protocol (RDP) has become the focus of competition, and...
