摘要:
The invention provides a novel method for enhancing user experiences, especially when changing channels, in digital video broadcasting systems. The invention provides a mechanism to show a low resolution version of the contents immediately after the channel change, and then automatically switch to the high resolution content once the new GOP is started, thus the user will not see blank screen during the waiting period.

A method and system for preventing skipping the playback of a special content section of a digital media stream is provided. The method comprises a method for providing a digital media stream on the providing side, and a method for playing back a digital media stream as provided by the above providing method on the playing back side. The providing method comprises: decoding an encoded special content section of a digital media stream; generating an encryption key based on the decoded data of the special content section; encrypting a normal content section of the digital media stream using the encryption key; and providing the digital media stream comprising the encoded special content section and the encrypted normal content section. The playback method comprises: receiving the digital media stream; decoding the special content section of the digital media stream; generating an encryption key based on the decoded data of the special content section by using the same method for generating the encryption key in providing the digital media; decrypting the normal content section of the digital media stream using the encryption key; and playing back the special content section and normal content section of the digital media stream.

The present invention provides a multimode communication terminal which contains at least a first separate channel module and a second separate channel module. The multimode communication terminal can be configured to communicate by using the first channel module and/or the second channel module. The channel modules communicate according to different communication protocols. The multimode communication terminal further comprises: channel switch layer means for switching the first channel module to have parameter characteristics consistent with those of the second channel module, so that the multimode communication terminal enables the MIMO operation mode by using the first channel module and the second channel module at the same time. The present invention further provides a method for enabling a MIMO operation mode in a multimode communication terminal. By using a relatively small number of RF communication modules, the present invention implements a wireless mobile multimode communication terminal which enables various operation modes including the MIMO operation mode. Compared with the existing solutions, the present invention greatly reduces the size required by the terminal.

A method for enabling a MIMO operation mode in a multimode communication terminal includes switching a first channel module to have parameter characteristics consistent with those of a second channel module, so that the multimode communication terminal enables the MIMO operation mode by using the first channel module and the second channel module at the same time. The method also includes extracting corresponding parameters from the second channel module and configuring the first channel module to be switched with the extracted parameters, such that the first channel module and second channel module enable the multimode communication terminal to perform MIMO communication. The method further includes issuing, upon determination of a switch, notification instructions to means in channel switch layer means and changing a data channel associated with the first channel module, such that the first channel module and second channel module can be adapted to the MIMO operation mode.

摘要:
A device and method for compensating for delays of a plurality of communication channels, provides signals with a certain frequency range, wherein the signals form standing waves in the plurality of communication channels; calculates phase differences between the plurality of communication channels according to the signal frequencies at the peak values of the standing waves; and determines the delay of each communication channel according to the above phase differences. The device and method may be applied to the communication channels of high speed parallel connection to eliminate the delays of the communication channels and realize length matching. Since the device and method determine the delays of communication channels by means of the phase differences, even when the delay difference exceeds a clock cycle, it can calculate the phase differences properly.
