We consider the organization of the information in video sequences for transmission over an integrated wireless access network carrying a wide variety of services at different bit rates. The access network employs direct-sequence code-division multiple access at bandwidths of 5 or 15 MHz. Video calls at 64 kb/s or voice calls at a peak rate of 8 kb/s are admitted on demand depending on the existing interference profile within a cell and its neighborhood. The transmission of QCIF resolution video sequences at 10 frames/sec has been simulated. The video information is packetized into two priority layers, a high priority layer and a discardable enhancement layer. In addition to FEC, we employ an ARQ protocol with retransmission time-out set at 1 frame interval or 100 ms. With transmission power appropriate to bit error rates of 10-4, picture loss rates of less than one per hour can be achieved.
