The invention relates to a DVB condition receiving device integrating descrambling of basic data and normal data. The DVB condition receiving device comprises a demultiplexer, a controller, an unpacking module and a descrambling module, transport stream TS steam received by the demultiplexer comprises basic data and normal data which have different collection rates and the same program contents, the demultiplexer, the unpacking module and the descrambling module sequentially carry out demultiplexing, unpacking and descrambling operations on the received transport stream, wherein the controller is connected with the demultiplexer and receives a user priority level to start a basic data descrambling operation or a normal data descrambling operation according to different user priority levels. By adopting the DVB condition receiving device provided by the invention, two data contents with different resolutions can be received at a receiving end, two descrambling methods with different complexity can be integrated at the receiving end, and the two data contents and the two descrambling methods are respectively correspondent to adapt to watching demands of different users on digital television programs.

The invention discloses method and equipment for adjusting brightness and contrast. The method comprises the following steps of: acquiring a pixel value of a brightness section in a column diagram of an input signal, judging whether the brightness of the input signal meets an adjusting condition or not according to the relationship between the pixel value of the brightness section in the column diagram and a preset threshold value; and when the brightness of the input signal meets the adjusting condition, adjusting the brightness of the input signal; acquiring a pixel value of a contrast adjusting section in the column diagram of the input signal, acquiring the contrast of the input signal according to a configured contrast acquiring formula, and adjusting the contrast of the input signal. The invention realizes an adaptive adjustment of the brightness and the contrast of a television signal received by a PCTV.

The present invention relates to applications of an ecological protective apparatus for concrete dam tops and dam slopes belonging to the field of dam body protection. The applications herein comprise the following steps: firstly determining a location for disposing a plant pipe based on the size and features of a concrete dam; then preparing a plurality of single-unit plant pipes, opening pores on the pipe wall every 30-40 cm, wherein for horizontal layout of a pipeline, circular pores of5-10 cm pore diameter may be opened, and for longitudinal layout, a recessed cut opening of 5-8 cm may be opened; casting organic soil to a single-unit plant pipe 5; combining single-unit plant pipes which are filled with organic soil to form a plant pipe channel at the places whereat a pipeline needs arrangement; planting or sowing seeds at the openings of the plant pipes which have been installed; greenizing the concrete dam tops and dam slopes through plant growth. The applications of the present invention achieve greening of the dam body, and at the same time do not impose influence on the safety of dam body.

The invention provides a screen refreshing method according to a preset frame rate and a device. The method particularly includes that writing operation states of a plurality of frame buffers are preset to be idle states, expected time for refreshing a frame of data of a screen is calculated according to the preset frame rate, writing operation of the frame buffers in the idle states is carried out, one of the frame buffers in the idle states is selected to be used as a reading frame buffer, the writing operation state of the reading frame buffer is refreshed to be a busy state, reading operation of the reading frame buffer is carried out, read frame data are transmitted to an image display to be displayed, a reading operation time interval between a previous reading frame buffer and a next reading frame buffer is not shorter than the expected time, and the state of the reading frame buffer is refreshed to be the idle state after the reading operation is completed. The screen refreshing method and the device are used for reducing bandwidth of a system in a screen refreshing procedure.

A method for selectively culturing the specific cockscomb by chromosome chimera principle includes such steps as using automutation to generate chimeric plant as mother plant; treating the seeds of the said mother plant by gamma ray; selectively culturing the stable chimera of specific cockscomb; free crossing and collecting seeds at particular position; and targeted hybridization. The resultant varieties of cockscomb features different colours on its same inflore scence, flower, stem and leaf.

The invention discloses a method for improving the flowering quality of Begonia Audaita, and relates to the technical field of plant flowering regulation. The method comprises the following steps: (1) using kinetin at a suitable concentration to spray the leaf surface of the Begonia stalked Begonia seedlings in the flower bud differentiation stage; (2) timely weeding and preventing rust on the Begonia stalked Begonia during the growth period of the Begonia stalked Begonia ; Pour antifreeze water once before the flowering period, and it is advisable to freeze at night; (3) During the flowering period of Aoda Begonia, put the potted Begonia seedlings into the artificial climate room for warming and cultivation. The invention can not only increase the flowering rate, the total number of flowering and the number of flowers in the inflorescence, effectively prevent the phenomenon of dumb buds, but also can reduce the color difference between the inner and outer circles of the petals, improve the color saturation of the flowers, solve the problem of the deterioration of the flower color, and improve the quality of the begonia with big stems. Flowering quality and improving the utilization of Begonia flower resources have good promotion and application value.

The present invention relates to a novel railway ballast greening device and application thereof, and belongs to the railway ballast greening field. Cultivation pipes are arranged at outer sides of a concrete sleeper in a manner of being parallel with a rail, holes are formed in one side of the cultivation pipes, sections of the cultivation pipes are connected together through direct joints, multiple sections of the cultivation pipes are connected together to form one cultivation pipe unit, end ports of the cultivation pipes at a tail end of each cultivation pipe unit are sealed through end caps, end caps are provided with small holes, one end of each cultivation pipe unit is connected with a water inlet pipe while the other end is connected with a water discharge pipe, a water pool is provided with a water outlet, the water outlet is connected with the water outlet pipe and is used for providing water for the cultivation pipes, the water outlet is provided with a water inlet valve, the water discharge pipe is provided with a water discharge valve, support anchor bars are installed on pipelines where cultivation pipes are required for arrangement, the cultivation pipes are placed on the support anchor bars, the side of the cultivation pipes with the holes faces upwards, and the cultivation pipes are fixed through fixing rings. With adoption of the greening device and the application thereof, greening of railway ballasts is realized, no influences on stability of the railway ballasts are not caused.

The invention relates to a DVB (Digital Video Broadcasting) condition receiving device capable of descrambling integrated basic data and normal data. The DVB condition receiving device comprises a demultiplexer, a controller, an unpacking module and a descrambling module, wherein a transport stream TS received by the demultiplexer comprises basic data and normal data with different acquisition rates and the same program content, and the demultiplexer, the unpacking module and the descrambling module sequentially carry out the demultiplexing, unpacking and descrambling operation on the received transport stream; and the controller is connected with the descrambling module and receives user priorities so as to start up the basic data descrambling operation or normal data descrambling operation according to different user priorities.
