In general, in an aspect, second look advertising is enabled. During an original advertisement selection process at a network infrastructure, original-selection advertisements are selected for play back with a streaming format video on a viewer device. After the original advertisement selection process, the streaming format video is presented on the viewer device together with advertisements that are provided by a helper process and can include the original-selection advertisements or other advertisements or both.

The present invention relates to an apparatus and a method for configuring a control message in a broadcasting system for supporting a multimedia service based on an internet protocol. To this end, control information to be recorded in a payload of a control message to be configured is generated based on a table selected from among a plurality of tables for defining the information related to the generation and consumption of a hybrid content when a message type of the control message to be configured is determined to be a type for providing information related to the generation and consumption of a hybrid content. In addition, the information related to the type of the selected table is recorded in an optional field of the control message to be configured.

A media presentation and distribution system communicatively coupled to a client device is provided. The client device receives a media stream from the media presentation and distribution system via a network. The media stream includes media content and one or more tags. The client device further identifies in the received media content, the one or more tags, which corresponds to the overlay-graphic items. The client device further identifies candidate time-periods in the media content based on the one or more tags in the media content. At least one presentation attribute for the overlay-graphic items is identified based on the one or more tags in the media content. The client device further presents the overlay-graphic items at the candidate time-periods on the media content based on a degree of correlation between the identified tag in the media content and a corresponding context for the media content at the candidate time-period.

In some implementations, a device includes one or more processors and a non-transitory memory. In some implementations, a method includes determining that a video frame to be presented at a client device includes a portion that corresponds to a particular playback position within a video content item. In some implementations, the method includes obtaining audio data that corresponds to the particular playback position within the video content item. In some implementations, the method includes transmitting the audio data to the client device separate from the video frame.

Disclosed are a smart screen reverse projection method, a system, a device, a smart screen and a readable storage medium. The smart screen reverse projection method includes: connecting to a television (TV) device through a wireless network after the TV device is started; sending a reverse projection instruction to the TV device, and establishing a reverse projection transmission link with the TV device; and receiving a real-time video stream sent by the TV device according to the transmission link, decoding and playing the real-time video stream. The video picture played on the display screen can be reversely projected to the smart screen in real time, such that the user can continue to watch the video played on the display screen after leaving the TV device by using the smart screen, to improve the user's experience.

Optimizing media distribution of a media steam performed by at least one processor, is provided, including: receiving immersive media data for an immersive presentation from a content source; acquiring asset information corresponding to media assets in a set of scenes included in the immersive media data; analyzing characteristics of the media assets, from the asset information, used in the set of scenes to determine whether a respective media asset is unique among the media assets; and generating metadata information that uniquely identifies the respective media asset for reusing the respective media asset in the set of scenes, based on determining that the respective media asset is not unique among the media assets in the set of scenes included in the immersive media data for the immersive presentation.
