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.
