    摘要: 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.

    摘要: 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.

    摘要: 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.
