An Implementation of Rate-Adaptive IPTV System on DSP

Yen-Jen Chen, Chih-Chung Wang, and Jr-Jen Huang
Abstract—This paper proposes an implementation of rate-adaptive IPTV system on DSP. The system has a client-server based architecture. The server-side and client-side are communicated with network socket connection. The server-side hosting on the DSP platform encodes the video signal from the TV cable. The client-side using JavaScript Language decodes and plays the multimedia video of DSP server-side instantly. The video quality mechanism is controlled by network bandwidth detection to improve the video play quality. The client-side detects the used bandwidth of the video stream from the server-side. The bandwidth utilization information is sent to the server-side to adjust the video encoding rate. The DSP platform used for this work is TMS320DM6437 EVM, produced by TI, implementing H.264 and AAC Encoders. The Encoder program uses the codec source code wrapped by TI, which conforms to the xDAIS (eXpress DSP Algorithm Interoperability Standard), and it is integrated with TI DSP network developer's kit and TV tuner to implement a TV over the Internet with the channel selection control.

Index Terms—IPTV, H.264, AAC, DSP, Javascript, Tuner.
