  • Patent number: 9344476
    Abstract: A technique is disclosed for controlling data packet transmissions from a server to a client having a client buffer in accordance with a waiting mode and a dynamic mode. The waiting mode is performed before packets containing data encoded subject to a current bit rate have reached the client buffer; the dynamic mode is performed otherwise. In the waiting mode, down-switches to lower bit rates are allowed but up-switches to higher bit rates are disabled. In the dynamic mode, up-switches and down-switches are both allowed, with adjustments in the bit rate of packets controlled based, in part, on the amount of data contained within the client buffer when packets containing data encoded subject to the current bit rate first reached the client buffer. The two modes help avoid unnecessary rate switches.
