Mpeg2-ts audio and Video synchronization principle

First, Introduction The MPEG2 system is used for AV synchronization and time labels for system clock recovery in the 3 levels of es,pes and TS respectively. On the TS layer, the TS header information contains the program Clock Reference PCR (Programme clock Reference), It is used to recover the system timing clock STC, which is consistent with the encoder end. In the PES layer, the PES header information contains a timestamp of PTS (Presentation time Stamp) and Decode Timestamp

Compilation of device tree on Ubuntu

[SQL Server] database migration between SQL server computers

inconsistent, SQL Server may reject the user's access to the database. This issue is called isolated users. If you use the SQL Server 2000 DTS transmission login function to transmit the login and password, isolated users may be generated. In addition, access to the integrated Login Account of the target server in different domains with the source server may also lead to isolated users. 1. Search for isolated users. Open the query analyzer on the tar

However, after about one minute, you can open the DBF table, indicating that the analyzer will shut down the table after a period of time. -- You can export only a few fields.Select

First, the concept of PTS (presentation time stamps), DTS (decoder timestamps), CTS (Compositiontime): pts: The time that the receiver displays this frame on the display. The unit is 1/90000 seconds.

am335x (tq335x) study notes--touch screen driver writing

Several of the previous articles have been ported by configuring DTS for multiple drives, and then we are addressing tq335x's touch-driven issues. For various reasons, tq335x touch screen drive is provided by the module, and the Linux official kernel also does not have the drive source code with the touchscreen, the simple configuration of DTS is unable to complete the tq335x touch-driven porting work, ther

The mipi screen can display the logo on the kernel, but the u-boot cannot display the logo.

The mipi screen can display the logo on the kernel, but the u-boot cannot display the logo. Platform: rk3288 U-boot version: u-boot-2014.10 Kernel version: 3.10 Mipi screen model: LQ079L1SX01 Author: fulinux * ***** This article allows reprinting, but please note the Source: http://blog.csdn.net/fulinus **** Problem: The use of the mipi screen can display the logo in the kernel, but the kernel can display. Analysis: If the kernel can be used normally, it indicates that the hardware is correct.

How to use SQL Server Data Transformation Services to upsize an Access database

This article details how to use SQL Server Data Transformation Services to upsize an Access database Developers often use Access as a prototype or access to develop applications that are not critical. However, as the company's business grows, the problems to be solved become more complex and the access environment may not meet your needs. Currently, Access 2002 's. mdb and. adp files limit the length of a database to 2 GB. This means that almost every access and SQL Server developer will eventu

Version 0.9 ". The document is available at: 4 Device Tree Compilation because the kernel only recognizes a flat device tree in binary format, a special device tree compiler "DTC" is required to compile the device tree source file (. dts) binary file (. dtb). The DTC compiler checks the input file for syntax and semantics and checks the nodes and attributes according to the requirements of the Linux kernel, compiling the binary (. dtb) of the dev

Linux Device Tree Syntax detailed

Tags: address SCI Linux Data custom keyword need one of the relationshipsThe Linux kernel introduces the concept of the device tree starting from 3.x, which is used to separate the driver code from the device information . Before the device tree appears, all specific information about the device is written in the drive, and once the peripheral device changes, the driver code is rewritten. After the introduction of the device tree, the driver code is only responsible for processing the driver log

Understanding of the timer in item

The client initiates a contrast request to the server, and the request contains the thumbprint of the data that the client subscribes to The server checks whether the client's fingerprint matches the latest data If matched, the service side holds the connection If there are no related data changes within 30 seconds, the service side holds the connection for 30 se

ES, TS, and PS streams

, and its length varies, the Transfer Stream TS can construct a stream of multiple programs based on one or more time identifiers. The transfer stream is suitable for scenarios with many errors. The advantage of data packet transmission is that the information in the network can occupy different connection lines and be saved temporarily. Multiple Data streams are reused into a new data stream through data packet interlace. This facilitates the decoder to flexibly sort data packets in the appropr
