Techniques are disclosed for managing media playback among an ad hoc group of playback devices. Such techniques may involve building a session among the playback devices in which playback devices communicate information regarding their playback capabilities. Based on the playback capabilities of the devices, playback mode may be derived for the session. Playback operations may be synchronized among the devices that are members of the session, in which devices receive identification of asset(s) to be rendered pursuant to the playback operation and timing information of playback of the asset. The devices may stream the playback assets directly from media sources when they are capable of doing so. In this manner, communication resources are conserved.

A system and method for remunerating a display of a cognate substitute image sequence is disclosed. Images sequences in received video content are examined for sequences that are cognate to known image sequences. When detected, such sequences are replaced with cognate substitute image sequences to create a modified video image stream that is displayed on a display screen. A reasonable remuneration for displaying the cognate substitute image is automatically calculated. This monetary charge reflects the nature of the image sequence, the time it was displayed for, the time at which was displayed and the number of electronic devices within viewing range of the display at the time of display. This remuneration is accumulated, and equivalent digital assets automatically transferred between client and provider accounts at an appropriate time.

In a system for broadcasting video programs to a user including a display, a system and method for providing program information or a copy of at least a portion of a program to the user. In one embodiment, a controller receives an input signal representing a request for summary information concerning a program, the program having a beginning and the input signal generated at a time during the broadcast. The controller provides via the display a summary of the program from the program beginning to the input signal time in response to the input signal. A controller may alternatively monitor a period of time during which the display is tuned to a broadcast of a program, the period starting during the broadcast. The controller is used to provide via the display a copy of at least a portion of the program when the period exceeds a predetermined threshold time.

An ad in a movie can be a static ad having a position in the movie that cannot be moved, or a dynamic ad having a position in the movie that can be changed. When a viewer wishes to skip a portion of the movie containing the ad, the playback system determines whether the ad is static or dynamic. If the ad is static, only the portion of the movie preceding the static ad can be skipped; the ad is unskippable. This technique is referred to as “bounceback” since the end of the skip bounces back to the start of the static ad. If the ad is dynamic, it is moved to after the end of the skip. This technique is referred to as “slip-ad” since the ad slips to later in the movie. When a movie has multiple ads, some can be static and some can be dynamic.

A method of acquiring access rights to conditional access content. The method comprises receiving an access right on a first terminal through a first communication channel; storing said access right in said first terminal; sending a request for said conditional access content to a content provider, said request containing at least an identifier of an account to which said first terminal is associated, an identifier of the requested content and a piece of information concerning said access right; verifying, by said content provider, the authenticity of said access right using said piece of information concerning the access right; and when there has been a successful verification, marking said access right as used, and sending said conditional access content to at least one terminal linked to said account. The first terminal using near field communication technology (NFC) during at least one transfer of said access rights.
