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.

Various embodiments of the present invention relate to a device and a method for detecting a black bar in video content in an electronic device. An electronic device comprises a display device, a processor, and a memory automatically connected with the processor, wherein the memory, when executed, can store instructions for allowing the processor to: play video content on the basis of a request relating to the playing of the video content; acquire, on the basis of the request relating to the playing of the video content, time information relating to the detection period of a black bar included in the video content; detect, on the basis of the time information, the black bar by using at least one image frame of the video content included in the detection period, when the detection period arrives while the video content is played; and adjust, on the basis of the black bar included in the video content and the resolution of the display device, the size of an image area of the video content being played. Other embodiments are also possible.

To allow subtitle bitmap data to be favorably superimposed onto video data on the reception side. A video stream having progressive video data is generated. A subtitle stream having progressive subtitle bitmap data is generated. A container including the video stream and the subtitle stream, in a predetermined format is transmitted. For example, the progressive subtitle bitmap data divided into top-field subtitle bitmap data and bottom-field subtitle bitmap data or not divided is present in the subtitle stream.

A stream playout and distribution system and method for disparate live media output stream playout and broadcast distribution are provided. The system generates a plurality of disparate live media output stream manifests, which comprises at least one of an index of a plurality of pre-encoded media assets or a plurality of live input streams, based on playout schedule and content viewing demographics. The system further generates a new version of at least one disparate live media output stream manifest based on insertion of a segment of at least one of a pre-encoded media asset or a live input stream into the disparate live media output stream manifest. Each segment corresponds to a different quality level and a different content encryption mode. The system further retrieves one or more broadcast content segments encoded in first encoding format of the new version, and converts retrieved broadcast content segments to second encoding format.

A stream playout and distribution system and method for disparate live media output stream playout and broadcast distribution are provided. The system generates a broadcast content schedule based on broadcast content parameters associated with programming content scheduled for a broadcast channel. The system further receives, encodes, and packages broadcast content to generate a plurality of encoded broadcast content segments. The system further generates a playout schedule based on insertion of a schedule for non-programming content in the broadcast content schedule, and then generates a plurality of disparate live media output stream manifests. The system further receives a disparate live media output stream manifest of the plurality of disparate live media output stream manifests, retrieves broadcast content segments encoded in a first encoding format, and converts the broadcast content segments to a second encoding format, wherein the second encoding format is in accordance with one or more broadcasting protocols.

A system and method for rendering a video stream for display on a display device, which may comprise receiving the video stream by streaming and generating display data defining a visible display area to be displayed by the display device, wherein said generating of the display data comprises rendering the video stream in a sub-area of the visible display area. A selection mechanism may be provided by which a version of the video stream may be selected for streaming having a spatial resolution and/or a bitrate which is selected based on a size of the sub-area. Thereby, the video stream may be adapted in terms of visual quality to the effective spatial resolution provided by the sub-area. For a smaller sub-area, it may be avoided to stream a version of the video stream which contains spatial detail which cannot be perceived when the video stream is rendered in the sub-area but which may incur more technical cost, e.g., in terms of required network bandwidth, decoding capabilities and decoding resource allocation, etc., than a video stream which has a lower resolution and/or lower bitrate and is thereby adapted to the size of the sub-area.

A method and apparatus, device, and storage medium for generating an image processing model and processing images based on the generated image processing model. The method includes generating an initial model for an image resolution processing, the initial model comprising an input layer, an output layer, and an intermediate layer; obtaining a training image comprising a first image and a second image, the first image being obtained by performing a resolution reduction processing on the second image; inputting image data of the first image into the intermediate layer from the input layer for a convolution calculation, and obtaining result data based on the convolution calculation, the result data comprising channel output data of N * N channels; and performing a parameter update on convolution kernel parameters in the intermediate layer based on the result data and the second image, and generating the image processing model according to the initial model.

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.

The present principles generally relate to methods, systems and apparatus for electronic program listing processing and/or display. In particular, the present principles relate to providing (330) an electronic program listing (400; 500) or the like which is capable of indicating to viewers programs with different resolutions of content by using different resolutions, or degrees of sharpness or blurriness of graphical representations (401, 402, 403, 404, 405, 406, 407, 408, 409; 510, 520, 530, 540) corresponding to the plurality of programs on the electronic program listing (400; 500). This way, a viewer is able to recognize easily and quickly which of the programs are, e.g., ultra high definition (UHD), high definition (HD), or standard definition (SD), just by glancing at the electronic program listing (400; 500).
