1. VOD VOD (Video On Demand) video-on-demand technology is one of the new business hotspots launched on the network in recent years (originally originated in Japan, the central computer system directly transmits movies or video programs to the family's home according to the user's on-demand demand Entertainment system. In the future, video-on-demand is expected to enter other interactive TV services, including games, banking and personal finance, shopping and education services). Divided into TVOD (True VOD referred to as VOD) and NVOD (Near VOD) two ways. For each TVOD request, TVOD must output a corresponding video stream, which requires very large network bandwidth. NVOD can support on-demand requests from any number of users. Although the bandwidth problem is solved, each user may have to wait for a long time to get the corresponding service. Three characteristics of TVOD: 1. Based on two-way network 2. Click and release 3. The number of concurrent streams is limited, the number of supported users is limited, and the cost per user is high Second, NVOD NVOD (Near Video On Demand) quasi-video on demand is one of the value-added services of the one-way digital TV system. It uses a video server to delay a digital TV program in several digital channels. The user can watch the program completely after waiting for a while while ordering the program. Five characteristics of NVOD: 1.NVOD broadcast control system software features: Graphical interface Program scheduling uses an intuitive graphical interface to distinguish different playback states with different colors Simple and clear operation Support mouse drag and drop selection, support to add programs in batch, easy to add and delete Automatic allocation of channel resources The system can automatically calculate and allocate the number of channels according to the program length and program interval Automatic detection of channel bandwidth Separation of programming and broadcasting For database operations. Program separation and broadcast separation can be achieved Program upload function support Program stream of local hard disk can be uploaded to video server Print function support Program schedule can be printed out, support print preview Automatically calculate the sum of the program bandwidth of all digital channels at the same frequency point during the program scheduling process, if the maximum value is exceeded (38Mbps in QAM64), a prompt message will be given 2.NVOD program form generation software features: Automatically extract data from the programming database to generate NVOD program forms Use MPEG-2 Private Segment (Private secTIon) for package transmission A single PID structure can be sent to the multiplexer for multiplexing output The program list is dynamically refreshed as the program schedule changes The TS stream is generated and output in memory, no files are generated, reducing the loss of the hard disk and increasing the TS stream generation speed The program form data contains the system real-time clock information of the front-end server, which is used to synchronize the set-top box clock with the front-end clock 3.NVOD (Near VOD) transmission network: based on broadcast network 4.NVOD advantages: no number of users, low unit cost 5. NVOD disadvantages: long waiting time (10-15 minutes)

Product Description
How to Select the Best Grow Light for your Greenhouse?
The plant needs light to thrive cause the light is essental for photosynthesis.without it,plants can not make food.but light can also be too intense,too hot or last too long for growing healthy plants.plant growth accelerates with abundant light because more of the plant`s leaves have exposure,which means more photosynthesis.in the winter,days are not long enough,but many plants still need 12 hours or more of light per day.

Now,adding LED Grow Lights to your greenhouse is an nice choice if you live in the north, and can not get enough daylight in winter.you might be take HID into consideration,cause it has high output and cover a wide area.but now,we providing you some dfferent.the newest type of grow lights use LED technology.
Provides Maximum Light Density and optimizing spectrum(410nm-740nm,white)
as we know that the plants need more light from the blue side of the spectrum during their seedling stage and when developing foliage and require light from the orange to red side of the spectrum while inblooming and fruiting phases. We adopting lastest intergrated COB technology, white , more red and blue PAR(410-740nm) per Watt than any other lighting fixture for the best color uniformity.
the Led grow lights feature selectable VEG and BLOOM light spectrums to deliver maximum performance from seeding through the flower stage and finally harvest.
Increase yields and potency
using high quality lense that hyper-focus the lights on your canopy.the photons are beamed directly to the plants.this gives growers the ability to get greatest possible crop yield.
Reduce your costs with energy efficiency
energy-efficient cannabis grow lights cost between 40%-60% less to operate compared to HID lam year.
Led Grow Light also eliminate the needs for ballasts and reflectors while they minimize the cooling systems,accelerating your payback.you will see the electrical bills trimmed by approximately half,year after year.
