An improved approach to tracking media playback includes tracking logic that is based on abandonment indicators. An abandonment indicator is detected during media playback, such as a user interaction with a computing device that is detected prior to ceasing playback of the media content. Tracking messages are reduced, suppressed, or suspended until an abandonment indicator is detected. After an abandonment indicator is detected, the system quickens, releases, or restart sending tracking messages to a collection system.

Disclosed are an audio information transmission system, method, and apparatus, and a corresponding two-wheeled vehicle and helmet. The system includes a media control apparatus and an audio switching apparatus connected to the media control apparatus. The audio switching apparatus is connected to a mobile terminal and the helmet and is configured to receive first audio information transmitted by the mobile terminal and transmit same to the media control apparatus. The media control apparatus is configured to receive and mix second audio information generated by the two-wheeled vehicle with the first audio information, to generate mixed audio information. The audio switching apparatus transmits the mixed audio information to the helmet. In the present application, the audio information transmitted by the mobile terminal and information such as navigation voices, alarms emitted by the two-wheeled vehicle are mixed. The mixed audio information is transmitted to the helmet, so that the user can obtain both the audio information transmitted by the user terminal and the navigation voices transmitted by the electric vehicle, without switching between the audio information from the mobile terminal and the navigation voices emitted by the electric vehicle. The user's driving safety is improved and the user experience is enhanced.

The present disclosure relates to a method and device for transmitting and receiving video content including three-dimensional (3D) data. The method of transmitting video content through a plurality of assets includes identifying whether content transmitted through an asset is a sub-picture; when the content transmitted through the asset is the sub-picture, generating sub-picture asset information comprising information about other sub-pictures constituting a composition picture together with the sub-picture; and transmitting the sub-picture asset information and the content.

A computer-implemented method/system of providing video clip playback, including: (i) receiving a video feed; (ii) converting the video feed into a compressed format structure; (iii) uploading the compressed format structure to a first server; (iv) receiving an electronic edit decision list defining how to manipulate the compressed format structure; (v) saving the electronic edit decision list to a server; (vi) receiving a request to provide to a user terminal a video clip playback corresponding to a video clip defined by the compressed format structure and the electronic edit decision list; (vii) sending to the user code executable to provide the video clip defined by the compressed format structure and the electronic edit decision list, and (viii) responding to requests from the code when executed, to provide content corresponding to the compressed format structure stored, in accordance with the electronic edit decision list, to provide the decision list video clip playback.

A method is provided for managing key rotation (use of series of keys) and secure key distribution in over-the-top content delivery. The method provided supports supplying a first content encryption key to a content packaging engine for encryption of a first portion of a video stream. Once the first content encryption key has expired, a second content encryption key is provided to the content packaging engine for encryption of a second portion of a video stream. The method further provides for notification of client devices of imminent key changes, as well as support for secure retrieval of new keys by client devices. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.
