Evaluation of Angda 720P HD VX555HD in the world of Xiao Tian Tian

"IT 168 evaluation center

Just yesterday, we evaluated OnStar's most amazing MP4 player VX797HD, because it is equipped with a huge 7.0-inch screen, and we also compared it with other OnStar MP4 products, one of which is VX555HD to be tested today. The contrast between VX555HD and VX797HD is quite large, because the screen size of VX555HD is only 3.0 inches. However, VX555HD still supports 10M bit rate 720P HD (1280? 720 resolution) live broadcast of RMVB/AVI movies.

In the official materials of Onda Electronics, we can see that Onda commented on VX555HD in this way: in addition to the comprehensive functional settings such as live broadcast of mainstream HD MP4 720P video, decoding of 10M stream and full fluency of colorless blocks, it will also launch an ultra-low price of 8GB/399 yuan, which is unprecedented in the history of HD? . Indeed, the price of 399 yuan is really ultra-low for a 720P player with 8GB of memory, but the 3.0-inch screen is too small to fully display the high-definition effect of 720 p.

"Small body, excellent workmanship:

The size of the screen can determine the size of the fuselage, which is a rule, so the Onda VX555HD with a 3.0-inch screen also has a small appearance, which is comparable to the early MP4 player. In terms of material, VX555HD implements the choice of Onda MP4 player, using advanced plastic material, while the frame design is sharper and more masculine. Most notably, the laser texture around the speaker on the back of the VX555HD fuselage gives the VX555HD a handicraft temperament.

The compact VX555HD can't carry two speakers, and the designed single speaker is small. Therefore, the volume of the speaker is not loud enough to play accurate sound effects. Of course, the sound we hear through headphones is very good, which can be verified by playing the preset songs of Devil's Seat and the songs of Hotel California and Ferry we added ourselves. Stereo surround sound is also very good, the restoration of human voice and instrumental sound is more accurate, and the heavy bass part is also very good.

On the right side of the screen of Onda VX555HD, the commonly used menu buttons are simply designed, which are responsible for calling menus or determining functional applications. The Micro SD memory card slot is designed on the lower side of the fuselage to support the expansion of large-capacity memory cards.

Onda VX555HD has a mini USB interface, a 3.5 mm headphone jack and a 3.5 mm video signal jack on the right side of the fuselage. There are multimedia buttons on the upper side of the fuselage, such as volume increase and decrease, fast forward/next song, play pause button, back/previous song, etc., which has good overall maneuverability.

"Accessories include:

Onda VX555HD also supports video output and is equipped with two video output lines. The video cable works very well and can effectively ensure the transmission of video signals. In addition, VX555HD provides accessories such as USB data cable, stereo earphone, rag, silicone sleeve, power adapter and instruction manual. Stereo headphones are common EP50 headphones of Onda, and the sound quality is good. Of course, friends who don't like it can also change other headphones with better sound quality.

"Disk reading and writing speed measurement, battery life:

Onda 3-inch 720P VX555HD

In the process of disk speed measurement, we still use ATTO speed measurement software to test Onda VX555HD. The test results show that the highest writing speed of VX555HD is 5.550MB/ s, and the highest reading speed is 6.396MB/ s, which keeps the level of VX535HD, VX797HD and other models. In addition, the battery capacity of VX555HD is unknown, but after playing two movies intermittently (about 4 hours) and playing 1 hour of music, the power consumption is about 40%, which shows that the power consumption of small screen is really much less.

"Main menu:

Onda 3-inch 720P VX555HD

The main menu of Onda VX555HD adopts a simple and intuitive design, and the screen content can be divided into two parts, the left part is the function option, and the right part is the corresponding function icon. From the menu, we know that VX555HD supports music, video, picture browsing, recording, radio, e-books, resource manager and setting functions.

"Video playback function:

In terms of video function, Onda VX555HD supports breakpoint playback, normal, full-screen and full-screen display modes, and supports two TV output types: high-definition output and normal output. At the same time, it can directly play video files in RM/RMVB, ASF, AVI, MP4, 3GP, MPG and other formats, and support 10M bit rate 720P HD (1280? 720 resolution) RMVB/AVI movie playback.

"720P video playback measurement:

Onda 3-inch 720P VX555HD

In the actual measurement of 720P movie broadcast, we downloaded several 720P RMVB and AVI movies from the Internet, including several video coding formats such as RealVideo 4, h264, MPEG-4 Visual, etc. The specific movies include Fantasy Companion Animation Series, Xie Anqi's Zhu Yingtai MTV, New York Gangster, Handsome Guy and Banquet, and VX555HD Body for testing.

During the test, we found that VX555HD can't play movies in h264 encoding format, but it can support two encoding formats, RealVideo 4 and MPEG-4 Visual. For example, when the playback bit rate is 1 147 Kbps, the width is 1280 pixels, the height is 720 pixels, the display ratio is 16: 9, and the frame rate is 24FPS, the movie will be smoother and more comfortable. In addition, users only need to copy the movie into VX555HD memory and play it smoothly without any conversion.

When playing a movie, VX555HD supports calling up the real-time control interface (as shown in the figure below), and can output the video to an external monitor (an external monitor needs a cable). In addition, because all the films we tested and played have detailed film information, we put these information together with the screen shots of the films, which intuitively proves the playback ability of VX555HD. (as shown in the figure below)

"IT 168 assessment center view:

After reading our evaluation reports on Onda VX797HD and VX555HD continuously, it is not difficult to find that VX555HD is a reduced version of VX797HD. Because the screen has dropped from 7.0 inches in VX797HD to 3.0 inches in VX555HD, they all support 10M bit rate 720P HD (1280? 720 resolution) live broadcast of RMVB/AVI movies. And the actual playback ability is the same, even the pictures, e-books and system settings are similar.

In addition, the price of Onda VX555HD is also a reduced version of VX797HD, because the listing price of VX797HD is 799 yuan (8GB version), while the listing price of VX555HD is 399 yuan (8GB version), which is different from 400 yuan. On the other hand, 799 yuan can buy two VX555HD, and you can also get change. However, the visual effect of VX555HD is far less than that of VX797HD, so friends who want to buy VX555HD should think carefully.
