Video-telephony and video-conferencing provide video services using ISDN (Integrated Services Digital Network). CCITT Recommendation H.261 is a video coding standard for these video services. This standard is also referred to as the px64 standard since the Video Codec (coder and decoder) operates at a rate on the communication channel p times 64 kbit/s (kilobits per second), where p is a positive integer no larger than 30. For p=1 or 2, a low quality video signal for picture phone and desktop face-to-face visual communication can be encoded and transmitted in real time with minimum delay. For a larger p (no less than 6), high quality pictures for video conferencing can be transmitted.
