The invention concerns a video feed monitoring app configured to be implemented with an interface and a processor. The interface may be configured to receive requests from an operator and present visual content to a display. The processor may be configured to process the requests and update the display. The video feed monitoring app may be configured to receive video streams from smart security devices, receive a priority signal, select a subset of the video streams in response to the priority signal and a user preference and arrange the subset of the video streams on the display. The priority signal may be generated externally based on events detected. The subset of the video streams may be updated based on the priority signal. Updating the subset of the video streams may comprise displaying the video streams that comprise events and removing the video streams that do not comprise events.

A method and a device for processing a multimedia file are provided. In some embodiments, for a multimedia file to be processed, payload data in the multimedia file is acquired, and the payload data includes multi-frame data forming the multimedia file. Some pieces of frame data are selected from the payload data as frame data to be encrypted, and the frame data to be encrypted is encrypted. New payload data is formed by the encrypted frame data and unencrypted frame data, and the new payload data is encoded to obtain an encoded multimedia file. Therefore, the protection of the copyrights of the multimedia file is achieved.

A display apparatus transmits a picture acquisition request for getting picture information to an external image apparatus connected through a predetermined interface to the display apparatus from the external image apparatus at predetermined intervals and gets a plurality of pieces of picture information from the external image apparatus to be displayed. The plurality of pictures may be switched at predetermined intervals, for example, to be displayed, so that the plurality of pictures may be displayed in a so-called slide show manner. A plurality of pictures for thumbnail may be produced from the plurality of pieces of picture information and be arranged together to be displayed in one picture screen of a display device.

Techniques for a smartphone-based conditional access (CA) system are described. In some embodiments, a headend in the CA system obtains a security profile associated with a pair of receiving devices used by a user, e.g., a first device (e.g., a smartphone) and a second device (e.g., a set-top-box or a TV). The headend dynamically regulates user access to requested media content during each entitlement period by assigning and distributing separate keys to the first and second device based on the security profile. The headend also uses the distributed keys to protect the media content before broadcasting. On the receiving end, one receiving device receives the media content and determines whether it is decryptable by the device. If decryptable, the receiving device (e.g., the set-top-box/TV) decrypts the media content using the keys assigned by the headend. Otherwise, the receiving device forwards the media content to the pairing device for decryption.

A method for content delivery using dynamic adaptive hypertext transport protocol (HTTP) streaming (DASH) without using HTTP. The method includes receiving a media presentation description (MPD) file and one or more DASH segments by a client device. Information in the MPD file is used to filter the one or more DASH segments. The filtered DASH segments are stored in a segments buffer. Particular DASH segments are requested from the segments buffer by the client device based on the information.

An image display apparatus and an image displaying method are provided. The image display apparatus includes a display; and a processor configured to parse information about a channel selected in response to a channel selection signal, determine whether to provide a plurality of services through the selected channel based on the parsed information, and, in response to the determining that the plurality of services are to be provided through the selected channel, obtain a plurality of service streams respectively corresponding to the plurality of services provided through the selected channel; and a decoder configured to decode one service stream from among the obtained plurality of service streams.

The present technology relates to a receiving device, a reception method, a transmitting device, and a transmission method capable of performing an effective filtering process. There is provided a receiving device including a filtering processing unit that performs a filtering process of a packet by using filtering information arranged in a header of the packet transmitted in a first layer that is a layer upper than an IP layer in layers of a protocol of the IP transmission system in a broadcasting wave of digital broadcasting using an IP transmission system. The present technology, for example, can be applied to a television set.
