Abstract: Decoder retrieval timing information, ROI information and tile identification information are conveyed within a video data stream at a level which allows for an easy access by network entities such as MANEs or decoder. In order to reach such a level, information of such types are conveyed within a video data stream by way of packets interspersed into packets of access units of a video data stream. In accordance with an embodiment, the interspersed packets are of a removable packet type, i.e. the removal of these interspersed packets maintains the decoder's ability to completely recover the video content conveyed via the video data stream.

Abstract: Intelligently downloading content to user devices is described herein. According to an embodiment, a user request for content is received. In response to the request, a low quality version of the content is downloaded and played to the user. Then, a higher quality version of the content is downloaded (this may occur during or after the download or playback of the low quality version of the content). Playback of the low quality version is discontinued. Then, playback of the higher quality version begins at the point where playback of the low quality version was discontinued. In some embodiments, the low quality version and the higher quality version of the requested content (among all the versions of the requested content) are identified via crowdsourcing.

Abstract: Methods and systems are provided for streaming a media asset with an adaptive bitrate transcoder. A server receives, from a client device, a first request for a first portion of the plurality of portions to be transcoded at a first bitrate. The server then starts to transcode the plurality of portions at the requested first bitrate to generate a plurality of corresponding transcoded portions. The server updates a header of a transcoded portion to include: 1) a transcode latency value; and 2) a count value indicating a number of available pre-transcoded portions of the media asset at the time the first request was received. The server then transmits the transcoded portion to the client. The client device then determines a second bitrate based on the transcode latency value included in the header of the transcoded portion corresponding to the first portion.

Abstract: Techniques for selecting TV user interface (UI) transition characteristics are described. In accordance with various embodiments, a transition characteristics selection method is performed at a device (e.g., a cloud UI engine on a server) with one or more processors and a non-transitory memory. The UI engine receives a request for transitioning from a first screen to a second screen on a client device while in a real-time content presentation mode. In response to receiving the request and while in the real-time content presentation mode, the UI engine obtains one or more presentation conditions of the client device and selects one or more transition characteristics for transitioning from the first screen to the second screen based on costs associated with the one or more transition characteristics and the one or more presentation conditions.

Abstract: Systems and methods for quick start-up of playback in accordance with embodiments of the invention are disclosed. Media content may be encoded in a plurality of alternative streams and a quick start-up stream. The quick start-up stream may include media content that is encoded at a lower quality that the alternative streams and may be encrypted with a different, less secure encryption process than that of the alternative streams. During a start-up of playback, the playback device streams the media content from a quick start-up stream until a metric, such as a decryption key for the alternative streams is met. The device then streams the media content from the alternative streams in response to the metric being met.

Abstract: A conversion method for converting luminance of a video, including a luminance value in a first luminance range, to be displayed on a display apparatus includes: acquiring a first luminance signal indicating a code value obtained by quantization of the luminance value of the video; and converting the code value indicated by the acquired first luminance signal into a second luminance value determined based on a luminance range of the display apparatus, the second luminance value being compatible with a second luminance range with a maximum value smaller than a maximum value of the first luminance range and larger than 100 nit. This provides the conversion method capable of achieving further improvement.

Abstract: A broadcast receiving includes a broadcast receiver that receives a broadcast wave of a digital broadcasting service; a separator that separates coded program video data, program-cooperation data, and screen layout control information, from the broadcast wave; a video decoder that decodes the coded program video data to reproduce program video information; a cooperation information generator that interprets the program-cooperation data to generate program-cooperation information; and a control unit that, when an instruction to display a given screen is input while the presentation processor divides video display region into sub-regions based on the screen layout control information, places the program video information in one of the sub-regions, places the program-cooperation information in another sub-region, and outputs the data of the video display region as the video information, outputs information of the given screen as the video information without dividing the video display region based on the screen layout control information.
