Abstract: Various schemes for realizing efficient in-loop filtering are described, manifested in low latency and reduced hardware cost for an in-loop filter comprising at least two filtering stages. An apparatus receives pixel data of a current block of a picture and one or more neighboring blocks thereof, based on which the apparatus performs a filtering operation and generates a filtered block that includes completely filtered sub-blocks and partially filtered sub-blocks. The apparatus further outputs an output block that includes the completely filtered sub-blocks as well as a respective portion of each of the partially filtered sub-blocks, wherein the respective portion is adjacent to one of the completely filtered sub-blocks.

Abstract: A VoIP terminal, which supports to make a phone call through both PSTN and Internet is disclosed. A local subscriber may choose to have a conversation through PSTN or Internet on his own. Besides, by reference to a switch such as a relay, the VoIP terminal is able to establish a PSTN connection under some special cases, such as the terminal power off or Internet shutdown.

Abstract: A voice speed adjusting system of VoIP phone and the method therefor are provided. When the parameter for adjusting the voice playing speed of IP phone is set to a setting module at a receiving end, an adjusting module is used to adjust the voice data stored in a cache accordingly. The adjusted voice data are processed and encoded/decoded by a CPU. An output module is used for outputting the adjusted voice data according to the speed parameter. A prompting module at the sending end displays that the receiving end is adjusting the voice speed. That is, a conversation can be conducted at an appropriate speed and the sending end can also receive a message of voice speed adjustment at the receiving end.
