| 20080307472 | Moving Image Viewing Apparatus - A moving image viewing apparatus or system automatically records on memory all available broadcast programs simultaneously on air even if power switch off. A list of the broadcast programs simultaneously on air is displayed for selection with the power switch on. The system retrieves the selected broadcast program from the memory during the preceding part of the same broadcast program is being recorded. Such an incomplete broadcast program as recorded on the way or given up in midstream is disposed not to be retrieved. The system allows the memory to automatically overwrite the recorded broadcast program with a new one after the recorded broadcast program has been retrieved to the end. Also unselected broadcast program is allowed to be automatically overwritten with a new one after the on air of the broadcast program is over. The overwriting can be inhibited if a user wants to save the broadcast program. | 12-11-2008 |

| 20090094652 | Methods and Apparatus for Simultaneous Uploading and Streaming of Media - A method for a computer system includes receiving a request for a video file, determining whether the video file is currently being uploaded from a video source and stored in a memory, and when the video file is currently being uploaded, the method includes determining a size of the video file that is currently being uploaded, providing the size of the video file to a video consumer, retrieving a portion of the video file that is stored in the memory, and providing the portion of the video file to the video consumer, when the video file is not currently being uploaded, the method includes determining whether the video file is in the memory, and providing the video file to the video consumer if the video file is in the memory, wherein the video file is transcoded to an appropriate format prior to being uploaded. | 04-09-2009 |
| 20090106803 | IPTV APPLICATION SYSTEM AND METHOD AND SYSTEM FOR PLAYING NEAR VoD PROGRAMS - An IPTV application system and a method and system for playing near video on demand (NVoD) programs. The system for playing NVoD programs includes: an IPTV application system, adapted to create NVoD channels and generate an NVoD channel table that contains attribute information indicating whether NVoD channels support time-shifting operations; an NVoD server that intercommunicates with the IPTV application system, adapted to play a program specified by an operator in a multicast and/or unicast mode following a scheduled timetable according to control of the IPTV application system. The present invention implements time-shifting under the NVoD state and adds to user experience under the NVoD state, and in addition, provides a new channel for operators to sell on-demand programs. | 04-23-2009 |
| 20090217331 | EFFICIENT NVOD SERVICE METHOD FOR VARIOUS CLIENT ENVIRONMENTS AND APPARATUS THERE-FOR - An efficient near video on demand (NVOD) service for various client environments is provided. The NVOD service method for transmitting video data including moving pictures to a plurality of clients in a network includes identifying a relative network bandwidth “m” of a client with respect to a video playout bandwidth, dividing the video data into data segments having different sizes according to the relative network bandwidth “m” and transmitting the data segments to the client through a plurality of channels. | 08-27-2009 |
| 20100043038 | SYSTEM AND METHOD FOR EFFICIENT VIDEO AND AUDIO INSTANT REPLAY FOR DIGITAL TELEVISION - A digital television system that includes an RF tuner, a transport stream demultiplexer, an audio decoder, a video decoder, a non-persistent memory, and at least one processor. The non-persistent memory is used to store audio and video packetized elementary stream (PES) packets demultiplexed by the transport stream demultiplexer based upon a broadcast signal received and demodulated by the RF tuner. During the process of decoding and presenting audio, video, and audio-video content on a display device of the television system, the at least one processor generates video records corresponding to each video PES packet and audio records corresponding to each audio PES packet. The video and audio records establish a one to one correspondence between each video PES packet and each audio PES packet and permits each video PES packet and each audio PES packet stored in the memory to be located, decoded, and re-displayed on the display device on the television system. | 02-18-2010 |

According to another embodiment a subscriber requests that broadcast programming be saved for the subscriber upstream from the subscriber in a television distribution system, and wherein the subscriber may request the programming be saved for later viewing by the subscriber between the time the programming was broadcast and a later point in time. | 10-03-2013 |
| 20130276043 | METHOD AND APPARATUS FOR REMOTELY TUNING CHANNELS USING DLNA DMS SERVICE - A particular implementation correlates a broadcast media item, which has a metadata element containing either a station call sign or channel number for a program, to a specific broadcast frequency and a virtual channel that a service provider broadcasts the program on. A command string is algorithmically defined to encode the frequency and physical channel, and is presented to the tuner hardware for locking onto and decoding the signal. A URL including the command string can then be generated. Consequently, a DLNA client device can engage a media renderer to play the broadcast media item through the exchange of a URL and a control interface. | 10-17-2013 |
