A system that stores plural reference measures, each reference measure corresponding to measured transitions of one or more video objects of plural successive pictures corresponding to a video scene, receives first and second measures of plural successive pictures corresponding to a first video scene received from a remote device, the first and second measures corresponding to measured transitions of a video object of the first video scene, compares the first and second measures with the stored plural reference measures, and indicates to the remote device whether a threshold percentage match exists between the first and second measures and one of the stored plural reference pictures.

In one embodiment, a method dynamically configures a BL bandwidth in a conference based on bandwidth capabilities in the video conferencing network. In one embodiment, the conference may include any combination of endpoints characterized as BL endpoints and SVCL endpoints. The method includes determining one or more bandwidth capabilities for a plurality of endpoints participating in a conference. The bandwidth capabilities for each respective endpoint may be based on its video decoding capability, the maximum bit-rate it can accept, the video encoding capability of the other endpoints, or a bandwidth constraint manifestation in a portion of the network, etc.

The invention can be viewed as a system for providing media information to a user via an interactive media services client device coupled to a programmable television services server device. A method of the preferred embodiment of the present invention includes receiving user input and excluding one or more media titles from a media title list based on the user input.

A system manages the allocation and storage of media content instance files in a hard disk of a storage device of a media client device in a subscriber television system. In one embodiment among others, the system includes a memory for storing logic, a buffer space in the hard disk for buffering media content instances as buffered media content instance files, and a processor configured with the logic to track the size of permanent media content instance files and the buffered media content instance files to provide an indication of available free space, such that the indication is independent of the buffer space.

The present invention provides a method for an interactive media services system to provide media to a user through an interactive media services client device. The client device is coupled to a programmable media services server device. The method includes the step of implementing an interactive media guide. Additionally, the client device is implemented to present the interactive media guide to the user. A system operator is provided an interface to the programmable media services server. Control options are provided within the interface to allow the system operator to configure a plurality of rental options available to the user. Finally the interactive media service system is implemented such that the plurality of rental options can be executed by the user in a requested active media session.

The present invention provides a method and system for accessing services in a television system. In one implementation, a DHCT presents a user a menu containing a plurality of selectable link representations corresponding to separate services or applications offered by the cable television system. The user navigates the menu with a remote device and selects a desired service by choosing the selectable link representation corresponding to the desired service or application. The DHCT receives the user input, translates the selectable link command into an executable call, and activates the service or application corresponding to the selected link representation from the menu chosen by the user.
摘要:
The present invention provides a system for providing alternative services in a television system. In one implementation, a subscriber is provided an alternative service upon attempting to access an unauthorized service, thereby providing a framework for efficient control of conditional access and enhanced services. In addition, in one implementation, user device limitations or variations are handled conveniently through the same multi-purpose system for providing alternative services.
