This document specifies the end-to-end protocols and procedures for support of Packet Switched Video Telephony (PSVT) Services over cdma2000 networks. This document defines the end-to-end PSVT service and architecture. The Stage 1 requirements for the PSVT Service are specified in [42]. The end-to-end system design is described in [43].

PSVT provides support of one-to-one conversational video services between a PSVT Terminal and another PSVT Terminal or a video terminal on the Internet. The procedures specified in this document are based upon procedures in [1][2][3][4][6][7][8][9][10][12][13][17][18][19]. If there is a conflict between the procedures in this document and those in the above referenced standards, the procedures in the referenced standards take precedence.

In this document, several key words are used to signify the requirements. The key words "shall", "shall not", "should", "should not" and "may" are to be interpreted as described in [20] and the TIA Engineering Style Manual.
