Apparatus for transmitting broadcast signals, apparatus for receiving broadcast signals, method of transmitting broadcast signals and method of receiving broadcast signals
The present invention proposes a method for providing a broadcast content in an apparatus, the method comprising: requesting a filter code to an application running on the apparatus by using a first Application Programming Interface (API); receiving a JavaScript Object Notation (JSON) object from the application in response to the first API; storing the filter code; receiving an Extended File Delivery Table (EFDT) having a first filter code associated with a first file; and selectively downloading the first file by comparing the stored filter code with the first filter code in the EFDT.
Apparatus, systems and methods for content availability notification
Systems and methods are operable to notify a user of content availability. An exemplary embodiment receives a content availability notification request that specifies at least one content of interest, searches current electronic program guide (EPG) information to identify the content of interest, determines that the information identifying the specified content of interest is unavailable based upon the search of the current EPG information, generates a content availability reminder that is associated with the specified content of interest, monitors a content database to determine an availability of the specified content of interest identified in the content availability reminder, determines that the specified content of interest is available when the monitored content database indicates availability of the specified content of interest, and generates a content availability reminder notification that indicates at least a title of the specified content of interest.
PROGRAM GUIDE SYSTEM WITH VIDEO-ON-DEMAND BROWSING
An interactive television program guide system is provided in which a viewer may direct a television to simultaneously display a selected television program and a program guide display. A viewer may use the program guide display to browse available video-on-demand (VOD) while continuing to view a previously selected program in the background. The viewer may browse through video-on-demand programs on the program guide display using a variety of keys on a remote control unit. The viewer may direct the program guide to order a given video-on-demand program/and set a desired broadcast time for that program.
METHOD FOR TRANSMITTING SERVICES INFORMATION IN DIFFERENT TYPES OF BROADCASTING NETWORKS AND UNIT FOR PROCESSING SAID INFORMATION
A method for transmitting services information in a broadcasting network by at least one managing center towards a plurality of receivers includes exploring streams broadcasted by a DVB network and streams broadcasted by an IP network and extracting services information from these streams, completing an information table, situated at the highest level in a hierarchy of services information tables, included in the service information DVB-SI transmitted by the DVB network by services information related to the IP network, and transmitting the completed information table in the streams broadcasted by the DVB network towards the receivers having two switchable receiving modules, connected respectively to a DVB and an IP services broadcasting network. The receivers are able to activate the reception of digital data of a service, equivalent to the service currently received, with a second receiving module when receiving conditions of a first receiving module are degraded.
BROADCASTING SIGNAL TRANSMISSION DEVICE, BROADCASTING SIGNAL RECEPTION DEVICE, BROADCASTING SIGNAL TRANSMISSION METHOD, AND BROADCASTING SIGNAL RECEPTION METHOD
A broadcasting signal reception device according to an embodiment of the present invention may comprise: a reception unit for receiving, through the broadcasting network, a broadcasting signal including a first component of a DASH content which can be received through a broadcasting network and a broadband network; a delivery module for de-capsulating the received broadcasting signal, outputting LCT packets transmitted through one or more LCT channels, and parsing signaling information used for acquiring segments corresponding to the first component of the DASH content included in the LCT packets; and a decoder for decoding the acquired segments.
TRANSMITTING DEVICE, TRANSMITTING METHOD, RECEIVING DEVICE, AND RECEIVING METHOD
The present invention enables a receiving side to easily recognize a high-quality format corresponding to encoded image data included in an extended video stream. Two video streams including a basic video stream including encoded image data of basic format image data, and an extended video stream including encoded image data of high-quality format image data of one type selected from a plurality of types are generated. A container of a predetermined format including the basic video stream and the extended video stream is transmitted. Information indicating a high-quality format corresponding to the encoded image data included in the extended video stream is inserted into the extended video stream and/or the container.
DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA
The present invention relates to a digital broadcasting system for transmitting/receiving a digital broadcasting signal and a method of processing data. In one aspect of the present invention provides a method of processing data, the method including receiving a broadcasting signal in which mobile service data and main service data are multiplexed, demodulating the received broadcasting signal, obtaining an identifier indicating that data frame of the broadcasting signal includes service guide information, decoding and storing the service guide information from the data frame; and outputting a service included in the mobile service data according to the decoded service guide information.
METHOD FOR TRANSMITTING BROADCAST SIGNALS AND METHOD FOR RECEIVING BROADCAST SIGNALS
A method for transmitting broadcast signals by an apparatus for transmitting broadcast signals, the method includes encoding service data according to a 16200 bit codeword and a 11/15 code rate based on addresses in a parity check matrix, wherein the encoded service data comprises information bits and parity bits; building at least one signal frame by mapping the encoded service data; modulating data in the built signal frame by an Orthogonal Frequency Division Multiplexing (OFDM) scheme; and transmitting broadcast signals having the modulated data, wherein the encoding of the service data comprises: initializing the parity bits, adding the information bits to the parity bits of which addresses are based on values of entries in each row of the parity check matrix, wherein a row of the parity check matrix corresponds to a 360 bit group of the information bits.
Method and device for adapting the video content decoded from elementary streams to the characteristics of a display
The present disclosure relates to a method and device for adapting a video content decoded from elementary streams to the characteristics of a display from at least one type of metadata giving information regarding said elementary streams. Such a method comprises:—obtaining (102) an additional information (HDR DESCR.) indicating the presence of one particular type of metadata;—determining if said video content decoded from elementary streams is display-able on said display (11) from said additional information (HDR DESCR.) and the characteristics of the display (EDID); and—if said video content decoded from elementary streams is determined as being displayable, selecting (105) a process from said additional information and the characteristics of the display and adapting (106) the video content according to the selected process.
Signaling for addition or removal of layers in scalable video
In one embodiment, a method of signaling individual layers in a transport stream includes: determining a plurality of layers in a transport stream, wherein each layer includes a respective transport stream parameter setting; determining an additional layer for the plurality of layers in the transport stream, wherein the additional layer enhances one or more of the plurality of layers including a base layer and the respective layer parameter settings for the plurality of layers do not take into account the additional layer; and determining an additional transport stream parameter setting for the additional layer, the additional transport stream parameter setting specifying a relationship between the additional layer and at least a portion of the plurality of layers, wherein the additional transport stream parameter setting is used to decode the additional layer and the at least a portion of the plurality of layers.
