Page 2: About Digital Video
CAYIN SMP Player Video Playback Guide 1. About Digital Video Video, also called motion picture, comprises a series of still images displayed in rapid succession at a constant rate. As digital video is getting popular nowadays, it has become a new and crucial technology to compress and store digital video files into digital media. Digital video has the following attributes:  Number of frames per second (frame/sec, or fps): Also called frame rate, this is the number of still images that are displayed per second. Generally, a higher frame rate will bring smoother and better video quality while ...
Page 3 CAYIN SMP Player Video Playback Guide players to deal with various codecs. Please refer to the following sections for a more detailed introduction and the codec information supported by CAYIN’s SMP player.  Bit Rate (bps): Video is usually saved after compression. If we divide compressed data size (in bit/s) by video length (in seconds), we will get bit rate (bits per second or bps) for this video. Take a 30‐second video file, for example. The file size is 6M bytes (=48M bits). If we don’t count the data size occupied by the file header and audio, we can say that the bit rate of this video file is about 1.6M bps (48/30=1.6). If we use the same compression method (codec), usually the higher the bit rate is, the ...

MPEG/MPG/VOB: MPEG Program Stream (MPEG‐PS) and MPEG Transport Stream (MPEG‐TS). MPEG‐PS is usually used for MPEG‐2 files or DVD. MPEG‐TS is a standard digital broadcasting format for digital TV and also is used in CAYIN’s CMS server’s RTB function. ...
Page 5 CAYIN SMP Player Video Playback Guide  MP4: MPEG‐4 Part 14, formally ISO/IEC 14496‐14: 2003, is the container format created with MPEG‐4 ISO.  WMV/WMA: Microsoft’s container format (with the same name as codec WMV/WMA) packs video information for WMV. This format can pack A/V data created by non‐WMV codec, but it is rarely used in this way.  AVI: An early release container format from Microsoft that is still widely used now Copyright @ CAYIN Technology Co., Ltd. 5 ...
Page 6: Compression Method (Codec)
CAYIN SMP Player Video Playback Guide 3. Compression Method (Codec) Compression is a very complicated but key process for reducing the size of video data. From early VCD (MPEG‐1) to DVD (MPEG‐2) and the latest blue‐ray disc (MPEG‐2 or H.264), video compression technology is constantly developed to lower bit rate but at the same time ...
Page 7 CAYIN SMP Player Video Playback Guide When a media player decodes any kind of codec format, the algorithm that codec uses plays an important role in system resource consumption of the media player (such as CPU, memory and graphics). Generally speaking, on the premise of the same bit rate, system loading of the four popular codecs MPEG‐2, MPEG‐4, WMV and H.264 will be as follows: H.264 > WMV > MPEG‐4 > MPEG‐2 With the same bit rate, the video quality after compression will follow the same order as above. Since the system resource consumptions are not the same, different bit rate limits will apply to the SMP media player based on the codec of video files. NOTE! Please refer to the appendix or the SMP user manual for suggested codec and bit rate. Patent Licensing: Most video/audio codec is protected by patent. CAYIN TECHNOLOGY is an official member of MPEG‐LA, Audio‐MPEG and Sisvel, which guarantee the legal usage of CAYIN’s products. Copyright @ CAYIN Technology Co., Ltd. 7 ...
Page 8: Other Factors To Influence The Media Player
CAYIN SMP Player Video Playback Guide 4. Other Factors to Influence the Media Player While reading video files or receiving network streaming, a media player needs to decode it first and then display it on a screen. The process is very complicated and requires the right combination of resources, including hardware, software and system capabilities. For example, the CPU is responsible for decoding and other operations, while memory provides the storage spaces needed before and after the decode. Graphic chips support the draw to the screen ...
Page 9 CAYIN SMP Player Video Playback Guide In portrait (rotation) mode, the system needs to map the actual desktop memory with the graphic output whenever the SMP player refreshes the screen.  Other Playback Elements The SMP media player does not play video only. In the application of digital signage, the SMP will play video files and other media contents at the same time, such as Flash, HTML, Ticker and Image. In these cases, hardware resources will be shared by all relevant media, influencing one another inevitably. For example, Flash is a powerful content creation tool, but, on the other hand, Flash content designers may not know the resource consumption of CPU, DRAM and graphics corresponding to the complexity of different Flash animation. Thus, when users play a Flash file with video and other programs simultaneously, sometimes it may reduce the ...

 PowerPoint (ppt) to Video Converter: “Wondershare PPT to Video” is an easy and simple PowerPoint to video file converter. Please refer to CAYIN’s “How to Convert PowerPoint to a Video for SMP Series” documentation for detailed information. Office 2010 can export PPT to WMV video directly.  Video LAN (VLC): A kind of multi‐platform playback software, the VLC player (Windows version) can be ...
Page 11: Faq - Regarding Video Playback
CAYIN SMP Player Video Playback Guide 6. FAQ – Regarding Video Playback  Video will stop or does not play smoothly. Usually this is because the video file exceeds the maximum limit of this SMP player, or the SMP player is playing other elements at the same time (such as Flash). We suggest you check the video content or other relative components. If video bit rate is too high, other components’ performance (such as Ticker) will be influenced as well. Try to find out which content reduces the overall play performance (i.e., uses the most player capabilities). If you play more than one video file at the same time (SMP‐WEBPLUS, ...
