Network Based Outdoor Media Player

The client was interested in designing small form factor network based media player which can support local playback as well as network playback with very less boot time.

AIM OF THE PROJECT

Productization of small form factor secured network media player with HDMI output. Player support playback on HDMI output to LCD/LED based TVs. The video files can be either stored on a local storage (USB Drive, MMC/SD) or streamed over the network. This media player supports HD resolution videos playback. The player has no user interaction except remote to play/pause/skip the current video. The player has to boot in less than a minute and the delay between the playing of 2 files should be less than 2 seconds.

THE CHALLENGE

It was a bit difficult to obtain less latency in video playback from the network. Even, to achieve less than a minute boot time was a challenging task in this project.
