Abstract: A video encoding and decoding method, device and system is disclosed, wherein the method includes: after using a standard encoding algorithm to complete encoding a luminance component in a current image, judging, based on refreshing images preset by an encoding device, whether there is a need to encode a chrominance component in the current image in accordance with the standard encoding algorithm or not, and encoding the corresponding chrominance component in accordance with the standard encoding algorithm if the current image is any one of the refreshing images preset by the encoding device, otherwise, not encoding the corresponding chrominance component in accordance with the standard encoding algorithm, wherein an encoding reconstruction of the chrominance component is obtained by copying a corresponding chrominance component in a reference image of luminance component, so that a finally output code stream does not comprise information of the corresponding chrominance component.

Abstract: The disclosure discloses a method for sharing a frequency spectrum between a GSM system and a LTE system. The method includes: avoiding fixed channels of the LTE system of a current cell when allocating frequency points of the GSM system to the current cell and a neighbor cell interfering with the current cell; frequency domain resources allocated to users and indicated by Physical Downlink Share Channels (PDSCHs) and Physical Uplink Share Channels (PUSCHs) of the LTE system are not located on same frequency resources with frequency points of the GSM system of the current cell and the neighbor cell interfering with the current cell.

Abstract: The disclosure discloses a signal processing method for a Long Term Evolution (LTE) base station side, wherein the method includes the following steps: in a downlink signal direction, filtering downlink signals at a baseband side to remove high frequency sub-carrier components, and extracting signals from the filtered signals with an extracting frequency fsd, wherein fw?fsd<(128/75)*fw, and fw is the frequency spectrum bandwidth of the LTE; in an uplink signal direction, first performing interpolation on uplink signals to increase the signal frequency, and then filtering the signals to add high frequency sub-carrier components. The method of the disclosure can effectively reduce the transmission rate of a baseband radio frequency interface without increasing the complexity of a radio frequency side.

Abstract: The present invention discloses a method for analyzing data, which comprises: judging whether the read of each multiplexing block in a media unit has been completed according to the total length of the media unit and the length of the multiplexing block when reading the multiplexing blocks in the media unit; the media unit is a video unit, an audio unit or a data unit. The present invention imposes the structural features of multiplexing blocks, when the receiving quality of the mobile media broadcasting terminal is well, which dispenses with judging whether the multiplexing block is the beginning multiplexing block or the ending multiplexing block according to the beginning ID code and the ending ID code, analyzing with type and data unit type field, and CRC. Therefore, the multiplexing block analyzer steps and the procedure of data process of the receiver are predigested. It performs quick analyzing.
