Abstract: Disclosed in the present specification are various embodiments regarding a digital device and a method for processing services on the digital device. Here, a method for processing an application on a digital device having a Web OS platform according to an embodiment of the present invention comprises the steps of: receiving a load request from a media application located in the foreground; generating a first media pipeline according to the received load request; if a resource assigning request is received from the first media pipeline, assigning the acquisition-requested resource to the first media pipeline; and receiving a playing request from the media application and then outputting the media.

Abstract: A method of operating a video display device including a display unit is provided. The method includes: playing uncompressed audio-visual content through a first layer of the display unit; obtaining content information on the uncompressed audio-visual content based on some of the uncompressed audio-visual content; obtaining an enhanced service based on the content information; and playing an obtained enhanced service through a second layer of the display unit, wherein the first layer and the second layer are overlapped each other.

Abstract: The present specification discloses a digital device and a control method therefor. Here, a digital device according to an embodiment of the present invention comprises: a pulse audio module for receiving, from an application, a first type audio data and a second type audio data different from the first type audio data; an audio processing unit; and an audio output unit, wherein the pulse audio module notifies the audio processing unit of the reception of the first and the second types of audio data, the audio processing unit controls the pulse audio module to adjust an output of the first and the second types of audio data on the basis of a policy associated with the first and second audio data, and the audio output unit outputs at least one of the first and second types of audio data on the basis of a result of the adjustment of the pulse audio module.
