specific Embodiment

[0117] Specific embodiments: the DMC application, DMR application, and DMS application on the IPTV set-top box go through the startup process, and then the DMC controls the DMR to render and play the media content on the DMS as an example to illustrate the working process of the technical solution.

[0118] The first is the boot process. This process is completed by the DMC application, DMR application, and DMS application calling the UPnP protocol stack. figure 2 In steps S00, S01, and enter into the waiting process of S02; image 3 In steps S10, S11, and enter into S12 waiting process; Figure 4 Steps S20, S21, S22, and enter the waiting process of S23.

[0119] Flow Description:

[0120] 1. The IPTV set-top box with DMC application, DMR application, and DMS application is added to the network, and the DMC application, DMR application, and DMS application are started at the same time. At the same time, it will read the configuration information in the configuration file...

Abstract

The present invention relates to a method for realizing DLNA media sharing by using a set-top box. An UPnP protocol stack which is realized based on an ISO / IEC29341 standard is selected as a component in a scheme. A media drive interface is taken as a component in the scheme. Based on the UPnP protocol stack, cooperated with an operating system socket API and a media drive interface in the set-top box, four types of equipment applications used under an IPTV set-top box application environment in a DLNA technical framework are realized: DMS equipment, DMP equipment, DMC equipment, and DMR equipment. According to the method of the invention, adding a media sharing function of the DLNA technical framework on an IPTV set-top box is realized, thus an IPTV set-top box can play a more important role in a home network environment and become central equipment of home media control gradually, people in a home environment can enjoy and share various entertainment media more effectively, and a way is paved for the development and expansion of other value-added services.

Description

technical field [0001] The invention relates to the realization of a DLNA (Digital Living Network Alliance) technical framework, in particular to a method for a set-top box to realize DLNA media sharing. The set-top box especially refers to a set-top box terminal (set-top box terminal device) in a home network, that is, a function of implementing a DLNA (Digital Living Network Alliance) technical framework on a set-top box terminal device (IPTV set-top box) in a home network. Background technique [0002] IPTV, that is, interactive Internet TV, is a technology that uses broadband cable TV network and integrates various technologies such as Internet, multimedia, and communication; it provides home users with a variety of interactive services including digital TV. The method of network set-top box + ordinary TV allows users to enjoy IPTV services in two ways at home. It can well adapt to the rapid development trend of today's network and make full and effective use of network...
