中國移動13日於「2010（第四屆）移動互聯網國際研討會」上聯合大唐電信、聯想、海爾、創毅視訊、CYWEE、華碩、三星、LG、Siliconimage、Mavell、博通、ATHEROS等12家廠商，共同１啟動了WiMo技術與產業合作。
所謂的WiMo（WirelessMobileMultimediaTransmitting），是指移動終端無線多媒體傳送技術的開發。此技術可支援移動終端與大螢幕設備之間無線、即時、高清音視頻資訊傳輸，可實現以移動終端為核心的多屏共用互動。也就是說，消費者可藉由WiMo技術，透過WIFI網路將手機裡的視頻內容同步傳輸到電視機等其他大螢幕終端。
中國移動研究院終端所副所長郭曉岩表示，目前中國移動已聯合合作夥伴完成了基於WiMo技術的可支援480P的晶片，並將在2011年推出支援1080P的晶片。預期在晶片推出之後，基於WiMo技術的終端研發將成為下一個突破點，中國移動更將與華碩合作推出一款可支持1080P體驗的OPhone終端。
在應用方面，中國移動研究院終端所則將與中國移動遊戲基地完成遊戲適配，並將與其他合作夥伴研發與WiMo技術相匹配的多媒體應用，預計分三階段進行：第一階段快速引入一批高品質的WiMo遊戲，第二階段豐富遊戲種類，第三階段與國內外合作夥伴合作設計全線的適合WiMo技術的遊戲。

TAIFATECH PC TO TV
TF-680 is a single chip HD streaming SoC that includes HD video codec and up to 7.1 channels
audio. TF-680 supports network connectivity via SDIO, USB or Ethernet interface that enables the
different connection methods. TF-680 compresses video and audio data and transmits them to
Ethernet or WiFi. It can also decompress video and audio data from WiFi or Ethernet and display
them on a TV. Image engine in TF-680 compresses video into MJPEG format and the support
resolution of video can be up to HDTV resolution. It decompresses MJPEG files and delivers video to
a display. Comparing with other compression methods such as MPEG1/2/4 and H.264, MJPEG
delivers very low latency bidirectional interactive mechanism which is the best solution for interactive
applications. Lip sync mechanism also designed in the TF-680 guarantees video and audio are in
sync.
TF-680 embeds scalar engine that can scale down the captured pictures and then transmits them into
network under limited network bandwidth.
Two UART, one I2C and one DDC are used for control purpose. Either AC’97 controller or I2S
controller are dedicated for audio input and I2S interface supports up to 7.1 channels audio. The ICE
interface provides the easiest way for software engineer to develop firmware and debug it. Ethernet
MAC is included in TF-680.
TF-680 has one IR which can be receivers or transmitters. TF-680 has two embedded PLL, one is to
generate different timing for different resolution display requirements and the other one is dedicated
for SDRAM high performance operations.
