  • Publication number: 20210227272
    Abstract: A channel playing method and a related device, to collect statistics on channel playing information of a terminal and update a mosaic channel bitstream and a played image based on a statistical result. In this way, subchannels of a mosaic channel are updated based on the playing information of the terminal, and the terminal device plays an adapted mosaic channel. The method performed by a video server includes: obtaining channel playing statistical information of a terminal; updating subchannels of a mosaic channel based on the channel identifiers in the channel playing statistical information; and sending a channel generation instruction to a mosaic generator to instruct the mosaic generator to generate a mosaic channel bitstream that includes the updated subchannels and channel identifiers of the updated subchannels, and the channel generation instruction includes the channel identifiers of the updated subchannels.

  • Patent number: 7339063
    Abstract: The present invention relates to compounds of quinolyl organic germanium ester having the following Formula 1 and the synthesis methods thereof. R1 and R2 are defined in the specification. Organic germanium acyl chloride and 8-hydroxylquinoline were used as the starting raw materials. Displacement reaction was carried out at 0-40° C., followed by hydrolysis reaction and then by changing the solvent, water soluble quinolyl organic germanium ester was finally obtained. The quinolyl organic germanium ester possesses better water solubility and fat solubility.

Displacement reaction was carried out at 0-40° C., followed by hydrolysis reaction and then by changing the solvent, water soluble quinolyl organic germanium ester was finally obtained. The quinolyl organic germanium ester possesses better water solubility and fat solubility. Due to the existence of both drug active group (organic germanium part) and drug recognizing group (quinoline part) in the structure of the quinolyl organic germanium ester, the compound is expected to develop a novel kind of anti-tumor drug.
