Vocallo Video
Vocallo supports applications such as 3G-324M, video phones, video-conferencing and video-enabled services with capabilities such as real-time video transcoding, video transrating and conferencing. Vocallo's media API integrates H.263, MPEG-4 and H.264 codecs and several real-time video processing functions. Access to uncompressed native YUV video bitmaps enables developers to integrate their own video processing algorithms along with Vocallo's software.

Network Video Support
Vocallo video codecs have been designed to address the unique challenges to deliver quality video on error-prone and bandwidth-constrained wireless networks. All codecs include error resilience and concealment techniques to minimize the effects of packet loss. The bit rate controller uses an advanced Variable Bit Rate (VBR) mode, which optimizes the trade-off between quality and bit rate allowing more channels to be carried on a given link. The unique integration of voice and video allows frame rate control that can gracefully reduce frame rates to manage network congestion while ensuring fluid playback and maintaining perfect A/V synchronization.
