| 20090144582 | ANTI-VIRUS METHOD BASED ON SECURITY CHIP - An anti-virus method based on a security chip according to the present invention is provided. The method comprises the following steps: a hash value obtained by a hashing operation for a computer key file and a system control program are stored in a memory of the security chip, and a backup file of the computer key file is stored in a backup storage area. When power up, the integrity of the system control program is verified by using the hash value of the system control program stored in the memory of the security chip. If the system control program is integral, a control is executed by the system control program, and the system control program verifies the integrity of the computer key file using the hash value of the computer key file stored in the memory of the security chip. If all the computer key files are integral, the operating system is started; on the contrary, if any of the computer key file is not integral, it will be restored using the backup file of the computer key file stored in the backup storage area. | 06-04-2009 |
| 20090276686 | METHOD TO SUPPORT FORWARD ERROR CORRECTION FOR REAL-TIME AUDIO AND VIDEO DATA OVER INTERNET PROTOCOL NETWORKS - A method and apparatus are described for protecting real time media including receiving media packets, generating media bit strings from the media packets, applying a forward error correcting code across the generated media bit strings to generate at least one forward error correcting bit string and generating at least one forward error correcting packet from the at least one forward error correcting bit string. Also described are a method and apparatus for recovering from losses of real time media packets including forming media bit strings from received media packets, forming forward error correcting bit strings from received forward error correcting packets, decoding the formed media bit strings and forward error correcting bit strings to obtain recovered media bit strings and recover lost media packets from the recovered media bit strings. Further described is a data structure for a forward error correcting header on computer readable media. | 11-05-2009 |
| 20090319846 | ADAPTIVE ERROR CORRECTION METHOD FOR DATA TRANSMISSION AND DEVICES THEREOF - An adaptive error correction method for data transmission and the devices thereof are disclosed. By comparing the announced recovery data and data requested for error correction, no redundant join messages will be sent if the recovery data have been announced before. This will greatly reduce the number messages and save the band width of transmission. | 12-24-2009 |
| 20090325526 | Method and apparatus for reporting state information - A method for reporting state information is provided. The receiver device receives a service, which is encoded in at least two layers over a communication channel, through a subset of said at least two layers; it measures a channel quality parameter; and in response to the channel quality parameter reaching a predetermined threshold value, it receives the service through a modified subset of the at least two layers as a function of the measured channel quality parameter and transmitting state information of the receiver device. Thus, the signal overhead is reduced. | 12-31-2009 |
| 20100058406 | SYSTEM AND METHOD FOR CONTENT COMMUNICATION - A system such as a multicast VOD system communicates content, e.g., delivers content or receives content, responsive to a user request for content and according to a schedule adapted to a user-specified acceptable latency for content delivery. The schedule may be modified to minimize initiation of delivery of content in response to the user's request. The schedule may also be modified to delay delivery of subsequent portions of the content as late as possible to allow subsequent requests to share a content stream while not exceeding the acceptable latency parameter specified by the user. | 03-04-2010 |
| 20100095181 | ADAPTIVE AND SCALABLE PACKER ERROR CORRECTION APPARATUS AND METHOD - An adaptive and scalable packet error correction apparatus and method in a wireless multicast network is provided. Each retransmission request from a receiver contains a round number and the number of repairs sent in that round. At each receiver, there are two counters for counting the rounds sent out on the network and the number of repairs that have been required. A receiver on the wireless multicast network listens to the ARQ requests sent by other receivers to update the two counters and determines whether its request should be suppressed or be sent out. | 04-15-2010 |
| 20100098108 | METHOD AND SYSTEM FOR TRANSMITTING IN TDM MODE - A method for transmitting data in TDM mode is provided to solve the problem in the prior art that the data processing between a transmitter side and a receiver side could not be real time and the delay time during data transmitting would be longer. The method comprises: packaging TIME DIVISION MULTIPLEXING (TDM) frame head information and data to be sent into a TDM frame at a transmitter side, and transmitting the TDM frame to a receiver side; receiving the TDM frame at the receiver side. With the solution according to the present invention, it is possible to perform real time data processing between the transmitter side and the receiver side and shorten the delay time during data transmitting. | 04-22-2010 |
| 20100279678 | DISTRIBUTION METHOD, OPERATION METHOD AND SYSTEM OF APPLICATION SYSTEM IN MOBILE COMMUNICATION NETWORK - A distribution method and an operation method and system of application system in mobile communication network are disclosed. The methods are adapted to mobile information field, which include: a mobile communication terminal establishes connection with an application system distribution platform through a mobile communication network; the mobile communication terminal uses the application system by an application system human-computer interaction module installed on the application system distribution platform; the application system and the human-computer interaction module run; an output process module of the application system distribution platform obtains a screen display image data of the human-computer interaction module, and sends it to the mobile communication terminal; the mobile communication terminal displays the screen display image of the human-computer interaction module, and sends an input information to the human-computer interaction module; step C and step E are repeated until the mobile communication terminal exit from the operation of the application system. The present invention can make an application system distributed on a mobile communication terminal, therefore, the network requirement is little, and the experience of the user is high. | 11-04-2010 |
| 20100318695 | ADAPTIVE KEYBOARD LAYOUT MAPPING - A method for processing keystrokes is described herein. A first keystroke representing a symbol for a first operating system may be received on a first computer. The first keystroke may be translated to a second keystroke representing the symbol for a second operating system on a second computer. The second operating system is different from the first operating system. The second keystroke may be sent to the second computer. | 12-16-2010 |
| 20110075599 | METHOD AND APPARATUS FOR MULTICAST GROUP MANAGEMENT - It provides a method for multicast group management. The apparatus determines a request for joining a multicast service derived during establishment of a connection for carrying multicast service between a first device and a second device, and it sends a message indicative of joining said multicast service based on the request for joining if the multicast service is not available in said network device. As a consequence, it reduces the messages exchanged in unreliable wireless connection so as to reduce the probability of service interruption. | 03-31-2011 |
