Problems solved by technology

However, when multiple DMCs are connected to one DMR at the same time, due to the different DMC implementation methods of each manufacturer, conflicts may occur during the push process
For example, DMC1 and DMC2 are connected to DMR1 together, and DMC1 pushes a media to DMR1 to play. At this time, DMC2 sends a STOP action to DMR1. Since DMC1 does not know that DMC2 is controlling DMR1 in the network segment, after DMC1 judges that DMR1 playback stops, It may continue to push the next media playback, causing the problem that DMR1 cannot stop
At this time, DMC1 and DMC2 have conflicts in control

Embodiment 1

[0067] See figure 1 , figure 1 It is a flowchart of a method for avoiding conflicts caused by multiple DMC push media playback in the present invention. figure 1 The shown method for avoiding conflicts caused by multiple DMC pushing media playback is applied in a DLNA home entertainment network to solve the problem of multiple DMCs simultaneously controlling DMRs with control conflicts, which specifically includes the following steps:

[0068] ●Step S1. According to the services and actions defined by the UPnP Universal Plug and Play Protocol, classify the content of the original agreement into'control actions' and'non-control actions', where the control action means that the DMC needs to apply for control before calling the DMR The right action, the non-control action refers to the action that does not need to apply for the control right before the DMC invokes the DMR. The action represents the command issued by the client to complete a specific function.

[0069] First, the catego...

Embodiment 2

[0109] See image 3 , image 3 It is a structural diagram of an apparatus for avoiding conflicts caused by multiple DMC pushing media playback in this embodiment. image 3 The shown device for avoiding conflicts caused by multiple DMC pushing media playback is applied to a DLNA home entertainment network to solve the problem of control conflicts when multiple DMCs simultaneously control DMRs.

[0110] image 3 The disclosed device for avoiding conflicts caused by multiple DMC pushing media playback in this embodiment specifically includes the following units:

[0111] 1. UPnP protocol content classification processing unit,

[0112] This unit classifies the content of the original protocol according to the services and actions defined by the UPnP Universal Plug and Play Protocol, and divides them into'control actions' and'non-control actions'. Control actions refer to those that need to apply for control rights before DMC invokes DMR. Actions, non-control actions refer to actions...

Abstract

The invention discloses a method for avoiding conflict of a plurality of DMC push media players. The method is applied to a DLNA (digital living network alliance) home entertainment network, and comprises the following steps: firstly classifying a service and an action for defining a UPnP (Universal Plug and Play) protocol to divide into a control action and an uncontrolled action, sending a request to a DMR (digital media renderer) in advance to apply for control right before a DMC (digital media controller) executes the control action on the DMR, recording an IP address of the DMC applying for the control right by the DMR, and only executing the control action sent by the IP address, wherein the DMR at most records a set of DMC equipment with the control right at the same time, the DMR filters the control action of the DMC without the control right, but can receive other state request actions. Through the adoption of the method, the control conflict is effectively avoided when the DMR is controlled by a plurality of DMCs, the relationship among a plurality of control equipment is optimized, the status of chaotic control is changed, and the use experience is greatly promoted.

Description

Technical field [0001] The invention relates to the technical field of network multimedia interconnection, in particular to a method and device for avoiding conflicts caused by multiple DMC push media playback. Background technique [0002] The full name of the Digital Living Network Alliance DLNA is DIGITAL LIVING NETWORK ALLIANCE, which aims to enable devices in the same network domain to realize free cross-device multimedia playback by integrating existing technologies and network protocols. In recent years, DLNA technology has been extensively developed, and more and more media devices, audio-visual terminals or playback platforms support DLNA. This technology allows devices to discover devices with other functions when connected to the network, and view and share media resources in the server to a certain player for playback. The types of DLNA devices mainly include DMP (Digital Media Player), DMR (Digital Media Renderer), DMS (Digital Media Server) and DMC (Digital Media C...
