The setting module is configured to configure prompt information of the videophone and the duration of a timer; the detecting module is configured to detect the terminal working state of videophone user in real time; the timing module is configured to perform timing; the transmitting module is configured to transmit the prompt information to the surroundings; the control module is configured to read the duration of timer and prompt information configured by setting module according to the terminal working state detected by detecting module, then to control the timing of timing module according to the read duration of the timer, and to start the transmitting module to transmit the read prompt information.

Abstract: An apparatus and method for generating a delta file reflecting changes between a prior version of a firmware and a new version of the firmware are provided. The method includes disassembling a binary file of the prior version and a binary file of the new version, identifying old basic blocks in the disassembled prior version, identifying new basic blocks in the disassembled new version, matching the new basic blocks with the old basic blocks, simulating an operation of an updater of a mobile terminal based on results of the matching, identifying differences between the simulation result and the new version, and generating the delta file based on the results of the matching and the identified differences between the simulation result and the new version.

Abstract: The present invention provides a method and apparatus for implementing automatic answering and recording in videophone services. The method comprises: when a video call is coming, a called terminal automatically answering the call and playing a prerecorded automatic answering prompting message to a calling user; and the called terminal recording audio and video of the calling user and ending the call after the recording is completed. The present invention has solved the problem that a videophone has no automation answering and recording function in prior art. Thus, the user can answer selectively video calls at anytime and anywhere, important video calls can be automatically recorded, and video calls which are inconvenient to be answered can be answered automatically by choosing various videos.

Abstract: A terminal and a method for prompting service failure in the video telephone service are disclosed, and the terminal comprises a processing module, a storing module and a setting module which are connected orderly. Said terminal sets and stores the corresponding relationship between different failure prompt information and prompting modes according to the user's command, and when the terminal receives a video telephone call request and the called user performs the failure prompting operation, the terminal generates a call failure prompt message according to the preset failure prompt information and the prompting mode corresponding to said failure prompt information and sends it to the calling user. After the calling user terminal receives said call failure prompt message, it analyzes and acquires the failure prompt information and the corresponding prompting mode, and displays and/or plays the failure prompt information to the calling user according to the prompting mode.

Abstract: A method for implementing information exchange is disclosed in the present invention, and the method comprises: a calling user terminal sending information to be sent to a called user terminal by carrying the information in a user-to-user signaling (UUS) field of a call message; the called user terminal sorting out the information carried in the UUS field from the call message after receiving the call message, and feeding back a message other than an acknowledge message to the calling user terminal; the calling user terminal terminating this call after receiving the message fed back by the called user terminal. The simplicity and the easy transformation of the software update of user terminals are fully utilized in the present invention; therefore the present invention can enable a user terminal to have the information exchange function only by properly modifying the software of the user terminal.

Abstract: The present invention provides a method and system for verifying a user alias. The method comprises: a calling terminal inserting a set alias and a calling user's own number into calling information when calling a called terminal; after the called terminal receives the calling information, when the calling terminal registers calling number display restriction or when the calling terminal cancels the calling number display restriction and the calling number of the calling is inconsistent with a calling user number stored locally in the called terminal, determining whether the calling user's own number matches successfully with the calling user number stored locally in the called terminal to display in different modes when the matching is successful and unsuccessful, respectively.

Abstract: A method of monitoring one or more central processing units in real time is disclosed. The method may include monitoring state data associated with the one or more CPUs in real-time, filtering the state data, and at least partially based on filtered state data, selectively altering one or more system settings.

Abstract: This disclosure provides intelligent frame skipping techniques that may be used by an encoding device or a decoding device to facilitate frame skipping in a manner that may help to minimize quality degradation due to the frame skipping. In particular, the described techniques may implement a similarity metric designed to identify good candidate frames for frame skipping. In this manner, noticeable reductions in the video quality caused by frame skipping, as perceived by a viewer of the video sequence, may be reduced relative to conventional frame skipping techniques. The described techniques advantageously operate in a compressed domain.

Abstract: The present invention provides a method and apparatus for a new interleaver adaptation scheme that achieves “error free” and zero delay (interleaving—triangular) or near zero delay variation (interleaving—GCI), and with easier implementation but no additional memory required. The dummy insertion methods and systems embodiments of the invention provide an effective dummy byte insertion scheme for applications that require seamless on-line rate changes, e.g., SRA (seamless rate adaptation), DRR (dynamic rate repartitioning) and adaptive INP (impulse noise protection).
