The emergence of live TV once shocked the public’s senses, but now web live broadcasts once again let people feel the magic of electronic digital technology, and any type of live broadcast requires the use of low-cost and high-quality HD and SD encoders, but want to make To play a better role and effect of high-definition encoder, it is necessary to know the following aspects when using it.

使用高标清编码器需要关注哪些方面

1. Pay attention to the access frequency of the encoder


The resolution and frequency used in video and audio live broadcasts are different, so not any kind of live broadcast can be performed with the same type of HD and SD encoders, and if the HD and SD encoders with the wrong frequency are connected, it will cause This live program or video and audio cannot be played smoothly. Even a reliable HD and SD encoder cannot solve the problem of frequency access errors and complete the live broadcast. Therefore, when using a HD and SD encoder, you must pay attention to the frequency that the encoder is connected to. .


2. Pay attention to the code rate format of the encoder


The unsuitable access frequency of the HD and SD encoder is the first reason that the live video and audio cannot be played. If the bit rate format of the selected HD and SD encoder does not meet the requirements, this situation will also cause the live broadcast to fail to play. This is because different encoders can recognize different formats, which is like our commonly used playback software. Only similar formats can recognize each other. Therefore, when using high-definition and standard-definition encoders, you must pay attention to whether their bit rate formats match.


Three, pay attention to the application environment of the encoder


Although the scope of use of HD and SD encoders is similar to that of ordinary encoders, from the point of view of its own characteristics, this encoder is more suitable for use in some TV live broadcasts, because some are used in web live broadcasts and recorded program playback. The playback software is relatively low in synchronization requirements. Therefore, the use of high-definition and standard-definition encoders must pay attention to where the environment is used, and where is the application in the playback state.


It is true that HD and SD encoders are more advantageous than old-fashioned encoders from their use effects to their actual playback operation methods. However, if you want to give full play to its performance, you must pay attention to the access of the encoder. Frequency, pay attention to the code rate format of the encoder, pay attention to the application environment of the encoder and other aspects.
