A multimedia content processing device for processing multimedia contents implementing a plurality of virtual machines is provided. The device is able to receive encrypted multimedia content, protected by a content protection system, and provide the multimedia content in decrypted form to a user device, including an access controller authorizing the provision of the decrypted multimedia content to the user device, a first securer for executing security services having a first associated level of security and a second securer for executing services having an associated level of security lower than the first level of security. The device includes a hypervisor able to control the execution of at least three groups of virtual machines, the groups of virtual machines being executed in a strictly separate manner, including, the first two groups being dedicated to executing services with a level of security lower than the first level of security and the third group of virtual machines able to implement security services with a first level of security and to act as trusted third parties for services of the first and second groups of virtual machines.

A method is implemented on a casting device to enable a follow-me mode in which the casting device controls display of media content on an output device coupled to the casting device. The casting device detects a client device associated with the casting device, and determines a proximity of the client device. In accordance with a determination that the client device is within a proximity threshold of the casting device, the casting device receives content information associated with content recently accessed by the client device, obtains the content from a content source in accordance with the content information, and outputs the obtained content to an output device in accordance with the content information.

Disclosed are a method and apparatus for recognizing advertisement plug-ins, relating to the field of computer technologies. The method comprises: searching for files related to application plug-ins; based on feature vectors of feature dimensions in a feature vector set of a predetermined advertisement, scanning the files related to the application plug-ins, and calculating feature vector similarity between data in each file and the feature vector in each feature dimension; calculating an advertisement similarity of a current application plug-in according to the feature vector similarity of each feature dimension and a feature recognition weight of the feature dimension; comparing the advertisement similarity with a threshold, and determining whether the application plug-in is an advertisement plug-in according to the comparison result. The method has the advantageous effects that a perfect feature recognition rule is involved, and there is a superior feature matching and recognition capability for obfuscated advertisement software codes.

The present disclosure relates to a method and a media device for pre-buffering media content streamed to the media device from a server system. The media device is connected to a network and has a rechargeable battery. The media device determines, by means of a bandwidth logic, an available network bandwidth and, by means of a charging logic, a charging level of the rechargeable battery. Based on these determinations, i.e. based on the determined available network bandwidth and the determined charging level of the rechargeable battery the media device selects a pre-buffering policy, by means of a pre-buffering logic, and pre-buffers media content, by means of the pre-buffering logic, from the server system in accordance with the selected pre-buffering policy.

A method in control equipment for synchronizing audio and video acquires an identifier of playback equipment. Information as to audio and video formats for the playback equipment is acquired playback and a first time delay data corresponding to the audio data and video data from the cloud server is set according to the identifier, the audio format information and the video format information. A first delay time between the audio data and video data according to the first time delay data acquired from the cloud server is set for the implementation of audio and video synchronization.

A display device disclosed includes a liquid crystal panel (6), and an image optimization circuit (4) for switching, in accordance with an update frequency of image data, between (i) a first mode in which a liquid crystal driver (7) is driven at a first driving frequency and (ii) a second mode in which the liquid crystal driver (7) is driven at a second driving frequency lower than the first driving frequency. The display device can therefore be used even in a case where a transmission path for image data is limited and optimally display high-resolution image data with reduced electric power consumption.

A system includes a set-top box and a remote device. The remote device receives data representing an event from the set-top box. The remote device determines whether the event has occurred based on the data representing the event and generates a transition command to transition the set-top box from a first operating mode to a second operating mode. Further, the remote device transmits the transition command to the set-top box if the event has occurred.

A method for providing a search service and a display apparatus applying the same are provided. According to the search service providing method, a search window for doing an Internet search is displayed on a partial area of the screen that displays an image. The search window can be converted into an image display window in response to receiving a specific manipulation input by a user, thereby allowing the user to use the search service while converting between the use of the search window and video watching.

A terminal device has a network interface that forces network connection when not connected to a network. The terminal device that has a network interface includes a connection check unit that makes a check as to whether the terminal device is connected to a network, and an invalidation unit that, when the connection check unit judges that the terminal device is not connected to the network as a result of the check, invalidates a function included in the terminal device.
