1. s60 uses a multimedia framework (MMF) for video and audio playback and recording. It has a plug-in architecture and can use multiple types of plug-ins for media playback and recording, for example, the RealPlayer engine is a plug-in for the MMF controller and supports video and audio playback and stream. 2. The s60 built-in player uses the RealPlayer engine. HTTP streaming media is not supported, because

Transplant sem600i (m608c) problem

-->The Chinese version is called m608c, a new business mobile phone, with touch screen, and most of the touchscreen phone is different, it does not have a quartet of keys and soft keys, but there are a bunch of letter keys, each button press the left and right half of the key values are not the same, the program needs to note that both key values must be captured. In addition to the left side of the phone has a knob, in the game to achieve the role of the upper and lower direction keys, because

How MongoDB stores data (reproduced)

memory data, write back to the swap partition, if not write back to the disk. MongoDB's storage model With memory-mapped files, the data to be accessed seems to be in memory, simplifying the logic of MongoDB accessing and modifying data MongoDB reads and writes only deals with virtual memory, leaving all the OS to take care of Virtual Memory size = All file size + some other overhead (connection, stack) If journal is turned on, the virtual memory size is almost doubled Benefits of using

HDU-2604 queuing (matrix fast power)

DescriptionQueues and Priority Queues are data structures which are known to most computer scientists. The queue occurs often in our daily life. There are getting people lined up at the lunch time. Now we define that 'F' is short for female and 'M' is short for male. if the queue's length is l, then there are 2L numbers of queues. for example, if l = 2, then they are FF, mm, FM, MF. if there exists a subqueue as FMF or fff, we call it o-queue else it is a e-queue. Your task is to calculate the

. HDCSFTTD, a European-branded German Rosenberg, offers a holistic approach to the profession. Body In the current mainstream building wiring system, the backbone of the network data transmission is composed by the optical cable, no matter what horizontal wiring scheme is used, there is no substantial difference in the trunk, and as the wiring scheme of the FTTD, the main difference lies in the horizontal wiring system that is from the floor distribution between the IDF through horizontal wiri

How to Apply multi-mode optical fiber connection in a data center (1)

) requirements specified by the transmission standard. The maximum channel distance of a Multimode Optical Fiber depends on the bandwidth performance parameter and the maximum insertion loss budget of the allowed Channel. For example, for a 300 m 10GBase-SR link using an 850nm OM3 optical fiber, the maximum insertion loss allowed is 2.6 decibels. In this 2.6 decibels budget, 1.1 decibels are used for the inherent loss of the optical fiber itself, and

How do I select single-mode or multi-mode optical fiber in the Integrated Wiring project?

How do I select single-mode or multi-mode optical fiber in the Integrated Wiring project? With the development of the times, copper cables will gradually exit the market and optical fiber cables will gradually become dominant. However, the types of optical fiber are single-mode optical fiber and multi-mode optical fiber. They share the advantages of optical fiber, but also have some differences. What are their advantages and disadvantages? What kind of optical fiber will we choose during integ
