This invention discloses a kind of reliable data transmission method based on hidden Markov model that specific to video transmission quality enhancement over lossy satellite links. It uses HMM model to forecast retransmission rate and adopts the network packet loss rate to reflect the network performance. The underlying network packet loss rate is used as the hidden state of HMM model and the retransmission rate is used as the observation state. By analyzing the historically transmitted data sessions, APRT establishes the relationship between the hidden state transition probability and the emission probability. Then, a robust and efficient retransmission rate prediction is obtained. This invention takes into full consideration of high BER in satellite network channels and adjusts the reliable level according to the satellite network channel characteristics so as to make tradeoff between instantaneity and quality. Consequently, it guarantee the QoS and QoE of video stream.

Embodiments are directed towards remotely generating encoding metadata at a remote content distributor for use by a local user computing device. The remote content distributor receives and encodes content. During or after the encoding process, the remote content distributor generates encoding metadata that indicates how the content was encoded by the remote content distributor. The remote content distributor provides the encoding metadata to the user computer device. The user computing device receives the content and the encoding metadata and encodes the content based on the encoding metadata. The user computing device can then provide the encoded content to another computing device for decoding and presentation to a user.

Disclosed is a tuner device including an input terminal, a separator, a first amplifier, a second amplifier, and a tuner. The input terminal receives an input of a reception signal of satellite digital broadcasts. The separator is connected to the input terminal and adapted to frequency-separate a first signal and a second signal. The first signal is in a low-frequency domain of the reception signal, and the second signal is in a high-frequency domain of the reception signal. The first and second amplifiers respectively amplify the first and second signals. The tuner receives an input of output signals from the first and second amplifiers.
