TS Stream decoding process:
1. Get Pat in ts
2. Obtain PMT From ts
3. You can know the video (audio) type (h264), corresponding PID, and pcr pid transmitted in the current network based on PMT.
4. Set the video filter of the Demux module to the PID and stream type of the corresponding video.
5. the payload data in the ts data packet obtained from the video Demux filter is one piece of PES. The ts header contains the number of p
equivalent to knowing the corresponding noise distribution of each image, and we are able to generate the image we want by selecting specific noise.2nd, this is not only the advantages of generating networks, but also has some limitations, which is to generate the network through the process of confrontation to distinguish between "real" pictures and "fake" pictures, but the resulting picture is just as true as possible, but this does not guarantee that the content of the picture is what we wan

Seq2seq
In the two models of many to many, the above figure can see that the fourth and fifth are different, the classical RNN structure of the input and output sequence must be equal length, its application scenario is relatively limited. And the fourth kind of it can be the input and output sequence is not long, this model is the SEQ2SEQ model, namely Sequence to Sequence. It implements the conversion from one sequenc

What kind of platform is capable of H.264 decoding
H.264 encoded files are usually used in the same way as MPEG-4 files. avi format, some also use the suffix name such as. tp or. ts, and you need to install the correct decoder and playback software to play it properly. For PC users, H.264 encoded video files will undoubtedly mea

What I do is a graduation design topic system, now in the familiar code. I know which function is implemented by which code, but I am very vague about the specific meaning of the code. Looking for a master to help me in the next note in the rear ~ ~
Since my project is old based on modifying some of the added features, it is sometimes necessary to add
Extract ($_post);Or
Extract ($_request);To run some features, what does that mean?
Also, I have to follow a few sentences behind every code that e
hierarchies are used as the key attribute of a dimension, you can still improve the performance by creating an index for Attribute members.
If the Attribute Hierarchy is disabled, these attributes are not applied.
In tasks within this topic, the Social Security numbers and other attributes in the "employees" dimension that are not used for browsing are disabled. The customer name and zip code attribute hierarchies in the customer dimension are hidden. A large number of attribute members
chip are supplied. This disturbance is called synchronous switch noise (SSN, simultaneous switching noise; SSO, simultaneous switching output noise) or Delta I noise in the power supply.When the PMOS tube is closed at the time t3, this action will not lead to the generation of pulse noise, because the PMOS tube has been in the open state and no current flow. At the same time, enable the NMOS tube. At this time, the transmission line, the ground plane

5. Addressing routing of SCCP:
The SCCP layer encoding function includes two aspects:
Ø address decoding
Ø select a reachable destination. The destination can be a subsystem of a certain signaling point or only a signaling point.
SCCP layer addressing routing method:
Ø DPC + SSN
Ø GT

The global title (GT) is a global name that makes sense globally

It has a return value of object, so you need to convert it to the appropriate data type.To demonstrate how serialization works in Java, I'll use the employee class mentioned in the previous tutorial, assuming we define the following employee class, which imple

deserializing an object.
Public final object readobject () throws ioexception, classnotfoundexception
This method retrieves the next object stream and deserializes it. The returned value belongs to the object type, so you need to convert it to the appropriate data type.
Let's take a look at an example. Here I will not translate it, but it will be displayed in English:

Oracle transparent data encryption (TDE) real-world use analysis, oracletde
Since the R2 version of Oracle Database 1Og, a feature called TDE makes data encryption extremely easy. All we need to do is to declare a column as encrypted, and the rest is done by Oracle. When a user inputs data, the column value is intercepted and encrypted, and then saved in the encrypted format. Then, when this column is queried, the column value is automatically decrypted, And the decrypted text (plaintext) is ret
